Block Diagram
The AT28C256 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 writ-
ing 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 opera-
tions. Following the initiation of a write cycle, the device
will automatically write the latched data using an internal
control timer. The end of a write cycle can be detected by
DATA POLLING of I/O7. Once the end of a write cycle has
been detected a new access for a read or write can begin.
Atmel’s 28C256 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
protection mechanism is available to guard against inad-
vertent writes. The device also includes an extra 64-bytes
of E
2
PROM for device identification or tracking.
