The EN29F002A / EN29F002AN is a 2-Megabit, electrically erasable, read/write non-volatile flash memory. Organized into 256K words with 8 bits per word, the 2M of memory is arranged in seven sectors (with top/bottom configuration), including one 16K Byte Boot Sector, two 8K Byte Parameter sectors, and four main sectors (one 32K Byte and three 64K Byte). Any byte can be programmed typically at 10s. The EN29F002A / EN29F002AN features 5.0V voltage read and write operation. The access times are as fast as 45ns to eliminate the need for WAIT states in high-performance microprocessor systems.
