... Description The AT28HC64B 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 with power dissipation of just 220 mW. When the device is deselected, the CMOS standby current is less than 100 µ ...

... The AT28HC64B is accessed like a Static RAM. When CE and OE are low and WE is high, the data stored at the memory location determined by the address pins is asserted on the out- puts. The outputs are put in the high-impedance state when either high. This dual line control gives designers flexibility in preventing bus contention in their systems ...

... Device Identification An extra 64 bytes of EEPROM memory are available to the user for device identification. By raising ±0.5 V and using address locations 1FC0H to 1FFFH, the additional bytes may be written to or read from in the same manner as the regular memory array. AT28HC64B 4 ® has incorporated both hardware and software features that will protect sense – ...
