9 / 68 page TC58FVM7(T/B)2AFT(65/80) 2002-10-24 9/68 Command Write The TC58FVM7T2A/B2A uses the standard JEDEC control commands for a single-power supply E2PROM. A Command Write is executed by inputting the address and data into the Command Register. The command is written by inputting a pulse to WE with CE = VIL and OE = VIH ( WE control). The command can also be written by inputting a pulse to CE with WE = VIL ( CE control). The address is latched on the falling edge of either WE or CE . The data is latched on the rising edge of either WE or CE . DQ0~DQ7 are valid for data input and DQ8~DQ15 are ignored. To abort input of the command sequence use the Reset command. The device will reset the Command Register and enter Read Mode. If an undefined command is input, the Command Register will be reset and the device will enter Read Mode. Software Reset Apply a software reset by inputting a Read/Reset command. A software reset returns the device from ID Read Mode or CFI Mode to Read Mode, releases the lock state if automatic operation has ended abnormally, and clears the Command Register. Hardware Reset A hardware reset initializes the device and sets it to Read Mode. When a pulse is input to RESET for tRP, the device abandons the operation which is in progress and enters Read Mode after tREADY. Note that if a hardware reset is applied during data overwriting, such as a Write or Erase operation, data at the address or block being written to at the time of the reset will become undefined. After a hardware reset the device enters Read Mode if RESET = VIH or Standby Mode if RESET = VIL. The DQ pins are High-Impedance when RESET = VIL. After the device has entered Read Mode, Read operations and input of any command are allowed. Comparison between Software Reset and Hardware Reset ACTION SOFTWARE RESET HARDWARE RESET Releases ID Read Mode or CFI Mode. True True Clears the Command Register. True True Releases the lock state if automatic operation has ended abnormally. True True Stops any automatic operation which is in progress. False True Stops any operation other than the above and returns the device to Read Mode. False True /Word Mode BYTE is used select Word Mode (16 bits) or Byte Mode (8 bits) for the TC58FVM7T2A/B2A. If VIH is input to BYTE , the device will operate in Word Mode. Read data or write commands using DQ0~DQ15. When VIL is input to BYTE , read data or write commands using DQ0~DQ7. DQ15/A-1 is used as the lowest address. DQ8~DQ14 will become High-Impedance. BYTE |
