7 / 35 page  This Data Sheet may be revised by subsequent versions ©2003 Eon Silicon Solution, Inc., www.essi.com.tw or modifications due to changes in technical specifications. 7 EN29F002A / EN29F002AN Rev. A, Issue Date: 2003/03/26 the Device Code can be read as 7F, 92 (hex) for EN29F002AT or as 7F, 97 (hex) for EN29F002AB (See Table 4). All identifiers for manufacturer and device codes possess odd parity with the DQ7 defined as the parity bit. Write Mode Write is used for device programming and erase through the command register. This mode is selected with CE = WE = L and OE = H. The contents of the command register are the inputs to the internal state machine. The command register is a set of latches used to store the commands along with the addresses and data information needed to execute that command. Address latching occurs on the falling edge of WE or CE (whichever occurs later) and data latching occurs on the rising edge of WE or CE (whichever occurs first). Temporary Sector Unprotect Mode EN29F002A allows protected sectors to be temporarily unprotected for making changes to data stored in a protected sector in system (n/a for EN29F002AN). To activate the temporary sector unprotect, the RESET pin must be set to a high voltage of VID (11V). In this mode, protected sectors can be programmed or erased by selecting the sector addresses. Once the high voltage, VID, is removed from RESET pin, all previously protected sectors will revert to their protected state. RESET Hardware Reset Mode (not available on EN29F002AN) Resetting the EN29F002A device is performed when the RESET pin is set to VIL and kept low for at least 500ns. The internal state machine will be reset to the read mode. Any program/erase operation in progress during hardware reset will be terminated and data may be corrupted. If the RESET pin is tied to the system reset command, the device will be automatically reset to the read mode and enable the system’s microprocessor to read the boot-up firmware from the FLASH memory. COMMAND DEFINITIONS The operations of the EN29F002A are selected by one or more commands written into the command register to perform Read/Reset Memory, Read ID, Read Sector Protection, Program, Sector Erase, Chip Erase, Erase Suspend and Erase Resume. Commands are made up of data sequences written at specific addresses via the command register. The sequences for the specified operation are defined in the Command Table (Table 5). Incorrect addresses, incorrect data values or improper sequences will reset the device to the read mode. |
