Description
The AT93C86A provides 16384 bits of serial electrically erasable programmable read
only memory (EEPROM), organized as 1024 words of 16 bits each when the ORG pin
is connected to V
CC
and 2048 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 operations are essential. The AT93C86A is available in space
saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead MAP, and 8-lead TSSOP packages.

AT93C86A [Preliminary]
3408D–SEEPR–04/04
The AT93C86A is enabled through the Chip Select pin (CS), and accessed via a 3-wire
serial interface consisting of Data Input (DI), Data Output (DO), and Shift Clock (SK).
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. When CS is brought
“high” following the initiation of a WRITE cycle, the DO pin outputs the READY/BUSY
status of the part. The AT93C86A is available in a 2.7V to 5.5V version.
Block Diagram
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 and the application does not load the input beyond the capability of the
internal 1 Meg ohm pullup, then the x 16 organization is selected. This feature is not available on the 1.8V devices.
