Description

Block Diagram
The AT28C64 is accessed like a Static RAM for the read
or write cycles without the need for external components.
During a byte write, the address and data are latched in-
ternally, freeing the microprocessor address and data bus
for other operations. Following the initiation of a write cy-
cle, the device will go to a busy state and automatically
clear and write the latched data using an internal control
timer. The device includes two methods for detecting the
end of a write cycle, level detection of RDY/BUSY (unless
pin 1 is N.C.) and DATA POLLING of I/O
7
. Once the end
of a write cycle has been detected, a new access for a
read or write can begin.
The CMOS technology offers fast access times of 120 ns
at low power dissipation. When the chip is deselected the
standby current is less than 100
μ
A.
Atmel’s 28C64 has additional features to ensure high
quality and manufacturability. The device utilizes error cor-
rection internally for extended endurance and for im-
proved data retention characteristics. An extra 32-bytes of
E
2
PROM are available for device identification or tracking.
