DESCRIPTION
The CAT93C86 is a 16K-bit Serial EEPROM memory
device which is configured as either registers of 16
bits (ORG pin at V_CC) or 8 bits (ORG pin at GND).
Each register can be written (or read) serially by using
the DI (or DO) pin. The CAT93C86 is manufactured
using Catalyst’s advanced CMOS EEPROM floating
gate technology. The device is designed to endure
1,000,000 program/erase cycles and has a data
retention of 100 years. The device is available in 8-pin
DIP, 8-pin SOIC and 8-pad TDFN packages.

For Ordering Information details, see page 12.
Notes:
(1) When the ORG pin is connected to V_CC, x16 organization is
selected. When it is connected to ground, x8 pin is selected.
If the ORG pin is left unconnected, then an internal pull-up
device will select the x16 organization.
