Product Summary

The AT28BV64B20SI is a high-performance electrically erasable programmable read only memory (EEPROM). Its 64K of memory is organized as 8,192 words by 8 bits. Manufactured with Atmel advanced nonvolatile CMOS technology, the AT28BV64B20SI offers access times to 200 ns with power dissipation of just 54 mW. When the device is deselected, the CMOS standby current is less than 20 μA. The AT28BV64B20SI is accessed like a static RAM for the read or write cycle without the need for external components. The device contains a 64 byte page register to allow writing of up to 64 bytes simultaneously.
