Miscellaneous:
The Microchip AT28HC64B is a high-performance
64Kbit Parallel EEPROM offering access times to 55ns with power dissipation of
220mW. Deselected, CMOS standby current is less than 100μA. Accessed 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.
