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 VCC and 128/256/512 words of 8 bits
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 ± 10%, 2.7V to 5.5V and 2.5V to 5.5V ver-
sions.

*NOTICE:
Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age to the device. This is a stress rating only and
functional operation of the device at these or any
other conditions beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect
device reliability
Note: 1. When the ORG pin is connected to VCC, the x 16 organization is selected. When it is connected to ground, the x 8 organiza-
tion is selected. If the ORG pin is left unconnected, then an internal pullup device will select the x 16 organization.
