The AT28C64B 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. During a write cycle, the
addresses and 1 to 64 bytes of data are internally latched,
freeing the address and data bus for other operations. Fol-
lowing the initiation of a write cycle, the device will automat-
ically write the latched data using an internal control timer.
The end of a write cycle can be detected by DATA POLL-
ING of I/O

. Once the end of a write cycle has been
detected, a new access for a read or write can begin.

’
s AT28C64B has additional features to ensure high
quality and manufacturability. The device utilizes internal
error correction for extended endurance and improved data
retention characteristics. An optional software data protec-
tion mechanism is available to guard against inadvertent
writes. The device also includes an extra 64 bytes of
EEPROM for device identification or tracking.
