Description
The AT28HC256 is a high-performance Electrically Erasable and Programmable
Read Only Memory. Its 256K of memory is organized as 32,768 words by 8 bits.
Manufactured with Atmel’s advanced nonvolatile CMOS technology, the AT28HC256
offers access times to 70 ns with power dissipation of just 440 mW. When the
AT28HC256 is deselected, the standby current is less than 5 mA.
The AT28HC256 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 al low writing of up to 64-bytes simultaneously. During a write
cycle, the address and 1 to 64-bytes of data are internally latched, freeing
the addresses and data bus for other operations. 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 28HC256 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 inadvertent writes.
The device also includes an extra 64-bytes of E2PROM for device identification
or tracking.
