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.
