Description
The AT59C11/22/13 provides 1024/2048/4096 bits of serial EEPROM (Electrically
Erasable Programmable Read Only Memory) organized as 64/128/256 words of 16
bits each, when the ORG Pin is connected to V
each when it is tied to ground. The device is optimized for use in many industrial and
commercial applications where low power and low voltage operation are essential.
The AT59C11/22/13 is available in space saving 8-pin PDIP and 8-pin EIAJ SOIC
packages.
The AT59C11/22/13 is enabled through the Chip Select pin (CS), and accessed via a
4-wire serial interface consisting of Data Input (DI), Data Output (DO), and Clock
(CLK). Upon receiving a READ instruction at DI, the address is decoded and the data
is clocked out serially on the data output pin DO, the WRITE cycle is completely self-
timed and no separate ERASE cycle is required before WRITE. The WRITE cycle is
only enabled when the part is in the ERASE/WRITE ENABLE state. Ready/Busy sta-
tus can be monitored upon completion of a programming operation by polling the
Ready/Busy pin.
The AT59C11/22/13 is available in 5.0V
sions.
