The PALCE6V8 is executed in a 20-pin 300-mil molded DIP, a 300-mil cerdip, a 20-lead square ceramic leadless chip carrier, and a 20-lead square plastic leaded chip carrier. The device provides up to 6 inputs and 8 outputs. The PALCE6V8 can be electrically erased and reprogrammed. The programmable macrocell enables the device to function as a superset to the familiar 20-pin PLDs such as 6L8, 6R8, 6R6, and 6R4. The PALCE6V8 features 8 product terms per output and 32 input terms into the AND array. The first product term in a macrocell can be used either as an internal output enable control or as a data product term. There are a total of 8 architecture bits in the PALCE6V8 macrocell; two are global bits that apply to all macrocells and 6 that apply locally, two bits per macrocell. The architecture bits determine whether the macrocell functions as a register or combinatorial with inverting or noninverting output. The output enable control can come from an external pin or internally from a product term. The output can also be permanently enabled, functioning as a dedicated output or permanently disabled, functioning as a dedicated input. Feedback paths are selectable from either the input/output pin associated with the macrocell, the input/output pin associated with an adjacent pin, or from the macrocell register itself. Configuration Table Power-Up Reset All registers in the PALCE6V8 power-up to a logic LOW for predictable system initialization. For each register, the associated output pin will be HIGH due to active-low outputs. Electronic Signature An electronic signature word is provided in the PALCE6V8 that consists of 64 bits of programmable memory that can contain user-defined data. Security Bit A security bit is provided that defeats the readback of the internal programmed pattern when the bit is programmed. Low Power The Cypress PALCE6V8 provides low-power operation through the use of CMOS technology, and increased testability with Flash reprogrammability. Product Term Disable Product Term Disable (PTD) fuses are included for each product term. The PTD fuses allow each product term to be individually disabled.

The leakage current is due to the internal pull-up resistor on all pins. 6. Not more than one output should be tested at a time. Duration of the short circuit should not be more than one second. V OUT = 0.5V has been chosen to avoid test problems caused by tester ground degradation. 7. Tested initially and after any design or process changes that may affect these parameters.
