Wear leveling is required since flash memory has a finite lifetime based on the number of writes and erasures to each individual block. The wear leveling algorithm in the VCX CFast 200 Series moves data to distribute block erases and writes across the available block population. The VCX CFast 200 Series uses flash devices to enhance endurance, retention and reliability Mean Time in Between Failures Using the Telcordia SR-332 specification at a temperature of 25 C, the Mean Time in Between Failures (MTBF) is calculated to be greater than three million hours. 4.3 Power Requirements 3.3V (±10%) single power supply operation 7

13 6.2 Device Configuration B1h The Individual Device Configuration Overlay command B1h is augmented by an additional command placed in the feature register. The subcommands are listed in Table 9. Value Table 11: Device Configuration Feature Field Values Commands C0h C1h C2h C3h Device Configuration Restore Device Configuration Freeze Lock Device Configuration Identify Device Configuration Set DEVICE CONFIGURATION RESTORE (B1h/C0h) The DEVICE CONFIGURATION RESTORE command provides a method for a host to restore any setting previously changed by a DEVICE CONFIGURATION SET command and to restore the content of the IDENTIFY DEVICE data, IDENTIFY PACKET DEVICE data, and other feature settings in a device to their factory default settings. The results of this action are indicated by the data returned from the Input Data of a DEVICE CONFIGURATION IDENTIFY command. DEVICE CONFIGURATION FREEZE LOCK (B1h/C1h) The DEVICE CONFIGURATION FREEZE LOCK command provides a method for the host to prevent accidental modification of a device's DCO settings. After a device has completed a DEVICE CONFIGURATION FREEZE LOCK command without error, the device shall return command aborted for all DEVICE CONFIGURATION SET, DEVICE CONFIGURATION FREEZE LOCK, DEVICE CONFIGURATION IDENTIFY, and DEVICE CONFIGURATION RESTORE commands until after the device processes a power-on reset. A device shall be in the factory_config state or the reduced_config state after processing a power-on reset. A device shall not exit the DCO_Locked state as the result of processing a hardware reset or a software reset. DEVICE CONFIGURATION IDENTIFY (B1h/C2h) The DEVICE CONFIGURATION IDENTIFY command causes a device to return a 512-byte data structure. The content of this data structure indicates the selectable commands, modes, and feature sets that the device is capable of disabling or modifying through processing of a DEVICE CONFIGURATION SET command. If a DEVICE CONFIGURATION SET command reducing a device's capabilities has completed without error, then: a) The response by a device to an IDENTIFY DEVICE, IDENTIFY PACKET DEVICE, and other commands, except the DEVICE CONFIGURATION IDENTIFY command, shall reflect the reduced set of capabilities; and b) The response to a DEVICE CONFIGURATION IDENTIFY command reflects the entire set of selectable capabilities. The phrase is changeable indicates that the feature may be disabled by the host using a DEVICE CONFIGURATION SET command. If the feature is not changeable then the device may support the feature but the DEVICE CONFIGURATION SET command shall not affect support of the feature. DEVICE CONFIGURATION SET (B1h/C3h) The DEVICE CONFIGURATION SET command allows a host to reduce the set of optional commands, modes, or feature sets supported by a device as indicated by a DEVICE CONFIGURATION IDENTIFY command. The DEVICE CONFIGURATION SET command may modify the data returned by IDENTIFY DEVICE or IDENTIFY PACKET DEVICE. When the IDENTIFY DEVICE data or IDENTIFY PACKET DEVICE data is changed, the device shall respond in a manner consistent with the new data. If a bit is set to one in the DEVICE CONFIGURATION SET data transmitted to the device that is not set in the DCO data received from a DEVICE CONFIGURATION IDENTIFY command, no action is taken for that bit. 13

14 Modifying the maximum LBA of the device also modifies the LBA value returned by a READ NATIVE MAX ADDRESS or READ NATIVE MAX ADDRESS EXT command.

DF (Device Fault) shall be set to one if a device fault has occurred. DRQ shall be cleared to zero. ERR shall be set to one if an Error register bit is set to one. Prerequisites: DRDY set to one. Description: This command is used by the host to request the device to flush the write cache. If there is data in write cache, that data shall be written to the CFast. The BSY bit shall remain set to one until all data has been successfully written or an error occurs. 6.5 Identify Device ECh Table 19: Identify Device Command Inputs Features Device Obs Obs DEV Command ECh 18

Normal Outputs: Table 20: Identify Device Command Normal Outputs Error Device Obs Obs DEV Status BSY DRDY DF DRQ ERR DEV specifies the selected device, Obs shows obsolete, shows Not Applicable. DF (Device Fault) shall be cleared to zero. DRQ shall be cleared to zero. ERR shall be cleared to zero. Prerequisites: DRDY set to one. Description: The IDENTIFY DEVICE command enables the host to receive parameter information from the device. When the command is issued, the device sets the BSY bit to one, prepares to transfer the 256 words of device identification data to the host, sets the DRQ bit to one, clears the BSY bit to zero, and asserts an interrupt if interrupts are enabled. The host may then transfer the data by reading the Data register. Table 8 defines the arrangement and meaning of the parameter words in the buffer. All reserved bits or words shall be zero. Some parameters are defined as a 16-bit value. A word that is defined as a 16-bit value places the most significant bit of the value on signal line DD15 and the least significant bit on signal line DD0. Some parameters are defined as 32-bit values (e.g. words (61:60)). Such fields are transferred using two successive word transfers. The device will first transfer the least significant bits, bits (15:0) of the value, on signal lines DD (15:0) respectively. After the least significant bits have been transferred, the most significant bits, bits (31:16) of the value, shall be transferred on DD (15:0) respectively. Some parameters are defined as a string of ASCII characters. 19
