GENERAL DESCRIPTION
The device is offered in a 56-pin SSOP package. A 12.0-volt VPP or 5.0 VCC is not required for program or erase operations. The device can also be programmed in standard EPROM programmers. The device offers access times of 65, 70, 90, and 120 ns, allowing high speed microprocessors to operate without wait states. To eliminate bus contention the device has separate chip enable (CE#), write enable (WE#) and output enable (OE#) controls. before executing the erase operation. During erase, the device automatically times the erase pulse widths and verifies proper cell margin. The host system can detect whether a program or erase operation is complete by observing the RY/BY# pin, or by reading the DQ7 (Data# Polling) and DQ6 (toggle) status bits. After a program or erase cycle has been completed, the device is ready to read array data or accept another command. The sector erase architecture allows memory sectors to be
