Description

The AT28BV64 is a low-voltage, low-power Electrically Erasable and Programmable

Read Only Memory specifically designed for battery powered applications. Its 64K of

memory is organized 8,192 words by 8 bits. Manufactured with Atmel’s advanced

nonvolatile CMOS technology, the device offers access times to 200 ns with power

dissipation less than 30 mW. When the device is deselected the standby current is

less than 50 µA.

The AT28BV64 is accessed like a Static RAM for the read or write cycles without the

need for external components. During a byte write, the address and data are latched

internally, freeing the microprocessor address and data bus for other operations. Fol-
