Description

The AT59C11/22/13 provides 1024/2048/4096 bits of serial EEPROM (Electrically
Erasable Programmable R ead Only Mem ory) organ ized as 64/128 /256 words of 16
bits each, when the ORG Pin is connecte d to V
each when it is tied to ground. The devic e is optimiz ed for use in many in dustrial an d
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 Chi p S el ec t pi n (CS ) , a nd ac ces sed via a
4-wire serial interf ace consis ting of Data In put (DI), Data O utput (DO), a nd Clock
(CLK). Upon receiving a RE AD i nstr uc tion at DI, the a ddr ess is dec od ed an d th e dat a
is clocked out ser ially on th e data output pin DO, th e WR ITE cycl e is complet ely self­timed and no separate ERASE cycle is required before WRITE. The WRITE cycle is
only enabled when the p art is i n the ERASE/W RITE E NABLE state. Ready /Busy
tus can be monitored upon completion of a programm ing operation by polling th e
Ready/Busy

The AT59C11/22/13 is available in 5.0 V ± 10%, 2.7V to 5.5 V and 2.5V to 5.5V ver­sions.
