Data Sheets:
The Microchip AT28BV256 is a high-performance
256Kbit 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.
