The Microchip AT28BV64B is a high-performance 64Kbit Parallel EEPROM offering access times to 200ns with 54mW power dissipation and 2.7V supply voltage. Deselected, CMOS standby current is less than 20µA. Access like static RAM for the read or write cycle without external components; it contains a 64-byte page register to allow writing of up to 64 bytes simultaneously. Optional Software Data Protection mechanism guards against inadvertent writes; and an extra 64 bytes of EEPROM enables device identification or tracking.
