AT28C64B General Description
The AT28C64B is a high-performance electrically-erasable and programmable read only memory (EEPROM). Its 64K of memory is organized as 8,192 words by 8 bits. Manufactured with Atmel's advanced nonvolatile CMOS technology, the device offers access times to 150 ns with power dissipation of just 220 mW. When the device is deselected, the CMOS standby current is less than 100 A. (continued)
