Product Description

AT28HC64B-12JU IC EEPROM 64KBIT PARALLEL 32PLCC Microchip Technology

Product Details



The AT28HC64B is a high-performance electrically-erasable and programmable readonly 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 55 ns with power dissipation of just 220 mW. When the device is deselected, the CMOS standby current is less than 100 µA.
