One icroamp Supply-Current, V to.v, 0kbps, RS- Transmitters/Receivers The Intersil ICLXX devices are.0v to.v powered RS- transmitters/receivers which meet ElA/TIA- and V.8/V. specifications, even at =.0V. Targeted applications are PDAs, Palmtops, and notebook and laptop computers where the low operational, and even lower standby, power consumption is critical. Efficient on-chip charge pumps, coupled with manual and automatic powerdown functions (except for the ICL), reduce the standby supply current to a µa trickle. Small footprint packaging, and the use of small, low value capacitors ensure board space savings as well. Data rates greater than 0kbps are guaranteed at worst case load conditions. This family is fully compatible with.v only systems, mixed.v and.0v systems, and.0v only systems. The ICLX are -driver, -receiver devices that provide a complete serial port suitable for laptop or notebook computers. Both devices also include noninverting alwaysactive receivers for wake-up capability. The ICL, ICL and ICL, feature an automatic powerdown function which powers down the on-chip power-supply and driver circuits. This occurs when an attached peripheral device is shut off or the RS- cable is removed, conserving system power automatically without changes to the hardware or operating system. These devices power up again when a valid RS- voltage is applied to any receiver input. Table summarizes the features of the devices represented by this data sheet, while Application Note AN98 summarizes the features of each device comprising the ICLXX V family.

9 Detailed Description ICLXX interface ICs operate from a single V to.v supply, guarantee a 0kbps minimum data rate, require only four small external capacitors, feature low power consumption, and meet all ElA RS-C and V.8 specifications. The circuit is divided into three sections: charge pump, transmitters and receivers. Charge-Pump Intersil s new ICLXX family utilizes regulated on-chip dual charge pumps as voltage doublers, and voltage inverters to generate ±.V transmitter supplies from a supply as low as.0v. This allows these devices to maintain RS- compliant output levels over the ±% tolerance range of.v powered systems. The efficient on-chip power supplies require only four small, external capacitors for the voltage doubler and inverter functions at =.V. See the Capacitor Selection section, and Table for capacitor recommendations for other operating conditions. The charge pumps operate discontinuously (i.e., they turn off as soon as the V and supplies are pumped up to the nominal values), resulting in significant power savings. Transmitters The transmitters are proprietary, low dropout, inverting drivers that translate TTL/COS inputs to EIA/TIA- output levels. Coupled with the on-chip ±.V supplies, these transmitters deliver true RS- levels over a wide range of single supply system voltages. Except for the ICL, all transmitter outputs disable and assume a high impedance state when the device enters the powerdown mode (See Table ). These outputs may be driven to ±V when disabled. All devices guarantee a 0kbps data rate for full load conditions (kω and 00pF),.0V, with one transmitter operating at full speed. Under more typical conditions of.v, R L =kω, and C L = 0pF, one transmitter easily operates at 900kbps. Transmitter inputs float if left unconnected, and may cause I CC increases. Connect unused inputs to for the best performance. Receivers All the ICLXX devices contain standard inverting receivers that three-state (except for the ICL) via the EN or FORCEOFF control lines. Additionally, the two ICLX products include noninverting (monitor) receivers (denoted by the R OUTB label) that are always active, regardless of the state of any control lines. All the receivers convert RS- signals to COS output levels and accept inputs up to ±V while presenting the required kω to 7kΩ input impedance (See Figure ) even if the power is off ( = 0V). The receivers Schmitt trigger input stage uses hysteresis to increase noise immunity and decrease errors due to slow input signal transitions. The ICL/// inverting receivers disable only when EN is driven high. ICL receivers disable during forced (manual) powerdown, but not during automatic powerdown (See Table ). ICLX monitor receivers remain active even during manual powerdown and forced receiver disable, making them extremely useful for Ring Indicator monitoring. Standard receivers driving powered down peripherals must be disabled to prevent current flow through the peripheral s protection diodes (See Figures and ). This renders them useless for wake up functions, but the corresponding monitor receiver can be dedicated to this task as shown in Figure. R XIN -V V RIN V kω Low Power Operation R XOUT V ROUT FIGURE. INVERTING RECEIVER CONNECTIONS These V devices require a nominal supply current of 0.mA, even at =.V, during normal operation (not in powerdown mode). This is considerably less than the ma to ma current required by comparable V RS- devices, allowing users to reduce system power simply by switching to this new family. Pin Compatible Replacements For V Devices The ICL// are pin compatible with existing V RS- transceivers - see the Features section on the front page for details. This pin compatibility coupled with the low Icc and wide operating supply range, make the ICLXX potential lower power, higher performance drop-in replacements for existing V applications. As long as the ±V RS- output swings are acceptable, and transmitter input pull-up resistors aren t required, the ICLXX should work in most V applications. When replacing a device in an existing V application, it is acceptable to terminate C to as shown on the Typical Operating Circuit. Nevertheless, terminate C to if possible, as slightly better performance results from this configuration. Powerdown Functionality (Except ICL) The already low current requirement drops significantly when the device enters powerdown mode. In powerdown, supply current drops to µa, because the on-chip charge pump turns off (V collapses to, collapses to ), and the transmitter outputs three-state. Inverting receiver outputs may or may not disable in powerdown; refer to Table for details. This micro-power mode makes these devices ideal for battery powered and portable applications. 9 FN80.

10 Software Controlled (anual) Powerdown ost devices in the ICLXX family provide pins that allow the user to force the IC into the low power, standby state. On the ICL and ICL, the powerdown control is via a simple shutdown (SHDN) pin. Driving this pin high enables normal operation, while driving it low forces the IC into its powerdown state. Connect SHDN to if the powerdown function isn t needed. Note that all the receiver outputs remain enabled during shutdown (See Table ). For the lowest power consumption during powerdown, the receivers should also be disabled by driving the EN input high (See next section, and Figures and ). The ICL, ICL, and ICL utilize a two pin approach where the FORCEON and FORCEOFF inputs determine the IC s mode. For always enabled operation, FORCEON and FORCEOFF are both strapped high. To switch between active and powerdown modes, under logic or software control, only the FORCEOFF input need be driven. The FORCEON state isn t critical, as FORCEOFF dominates over FORCEON. Nevertheless, if strictly manual control over powerdown is desired, the user must strap FORCEON high to disable the automatic powerdown circuitry. ICL inverting (standard) receiver outputs also disable when the device is in manual powerdown, thereby eliminating the possible current path through a shutdown peripheral s input protection diode (See Figures and ).

11 The INVALID output always indicates whether or not a valid RS- signal is present at any of the receiver inputs (See Table ), giving the user an easy way to determine when the interface block should power down. In the case of a disconnected interface cable where all the receiver inputs are floating (but pulled to by the internal receiver pull down resistors), the INVALID logic detects the invalid levels and drives the output low. The power management logic then uses this indicator to power down the interface block. Reconnecting the cable restores valid levels at the receiver inputs, INVALID switches high, and the power management logic wakes up the interface block. INVALID can also be used to indicate the DTR or RING INDICATOR signal, as long as the other receiver inputs are floating, or driven to (as in the case of a powered down driver). Connecting FORCEOFF and FORCEON together disables the automatic powerdown feature, enabling them to function as a manual SHUTDOWN input (See Figure ). POWERED DOWN UART Rx Tx V OUT = SHDN = CURRENT FLOW OLD RS- CHIP PWR GT LOGIC CPU FIGURE. CONNECTIONS FOR ANUAL POWERDOWN WHEN NO VALID RECEIVER SIGNALS ARE PRESENT With any of the above control schemes, the time required to exit powerdown, and resume transmission is only 0µs. A mouse, or other application, may need more time to wake up from shutdown. If automatic powerdown is being utilized, the RS- device will reenter powerdown if valid receiver levels aren t reestablished within 0µs of the ICLXX powering up. Figure illustrates a circuit that keeps the ICLXX from initiating automatic powerdown for 0ms after powering up. This gives the slow-to-wake peripheral circuit time to reestablish valid RS- output levels. POWER ANAGEENT UNIT I/O UART FORCEOFF FORCEON INVALID ICL// ASTER POWERDOWN LINE Ω FIGURE.

DISABLED RECEIVERS PREVENT POWER DRAIN ICL// FIGURE. CIRCUIT TO PREVENT AUTO POWERDOWN FOR 0ms AFTER FORCED POWERUP Automatic Powerdown (ICL// Only) Even greater power savings is available by using the devices which feature an automatic powerdown function. When no valid RS- voltages (See Figure ) are sensed on any receiver input for 0µs, the charge pump and transmitters powerdown, thereby reducing supply current to µa. Invalid receiver levels occur whenever the driving peripheral s outputs are shut off (powered down) or when the RS- interface cable is disconnected. The ICLXX powers back up whenever it detects a valid RS- voltage level on any receiver input. This automatic powerdown feature provides additional system power savings without changes to the existing operating system. FN80.

12 .7V 0.V -0.V -.7V FIGURE. DEFINITION OF VALID RS- RECEIVER LEVELS Automatic powerdown operates when the FORCEON input is low, and the FORCEOFF input is high. Tying FORCEON high disables automatic powerdown, but manual powerdown is always available via the overriding FORCEOFF input. Table summarizes the automatic powerdown functionality. Devices with the automatic powerdown feature include an INVALID output signal, which switches low to indicate that invalid levels have persisted on all of the receiver inputs for more than 0µs (See Figure 7). INVALID switches high µs after detecting a valid RS- level on a receiver input. INVALID operates in all modes (forced or automatic powerdown, or forced on), so it is also useful for systems employing manual powerdown circuitry. When automatic powerdown is utilized, INVALID = 0 indicates that the ICLXX is in powerdown mode.

AUTOATIC POWERDOWN AND INVALID TIING DIAGRAS INVALID } REGION PWR UP The time to recover from automatic powerdown mode is typically 0µs. Receiver ENABLE Control (ICL/// Only) Several devices also feature an EN input to control the receiver outputs. Driving EN high disables all the inverting (standard) receiver outputs placing them in a high impedance state. This is useful to eliminate supply current, due to a receiver output forward biasing the protection diode, when driving the input of a powered down ( = ) peripheral (See Figure ). The enable input has no effect on transmitter nor monitor (R OUTB ) outputs. Capacitor Selection The charge pumps require capacitors for.v operation. For other supply voltages refer to Table for capacitor values. Do not use values smaller than those listed in Table. Increasing the capacitor values (by a factor of ) reduces ripple on the transmitter outputs and slightly reduces power consumption. C, C, and C can be increased without increasing C s value, however, do not increase C without also increasing C, C, and C to maintain the proper ratios (C to the other capacitors). When using minimum required capacitor values, make sure that capacitor values do not degrade excessively with temperature. If in doubt, use capacitors with a larger nominal value. The capacitor s equivalent series resistance (ESR) usually rises at low temperatures and it influences the amount of ripple on V and. TABLE. REQUIRED CAPACITOR VALUES (V) C (µf) Power Supply Decoupling In most circumstances a bypass capacitor is adequate. In applications that are particularly sensitive to power supply noise, decouple to ground with a capacitor of the same value as the charge-pump capacitor C. Connect the bypass capacitor as close as possible to the IC. Operation Down to.7v ICLXX transmitter outputs meet RS- levels (±.7V), at full data rate, with as low as.7v. RS- levels typically ensure interoperability with RS- devices. Transmitter Outputs when Exiting Powerdown C, C, C (µf).0 to to to Figure 8 shows the response of two transmitter outputs when exiting powerdown mode. As they activate, the two transmitter outputs properly go to opposite RS- levels, with no glitching, ringing, nor undesirable transients. Each transmitter is loaded with kω in parallel with 00pF. Note that the transmitters enable only when the magnitude of the supplies exceed approximately V. FN80.

14 Interconnection with V and V Logic The ICLXX directly interface with V COS and TTL logic families. Nevertheless, with the ICLXX at.v, and the logic supply at V, AC, HC, and CD000 outputs can drive ICLXX inputs, but ICLXX outputs do not reach the minimum V IH for these logic families.
