CAT93C86/D
CAT93C86
16 Kb Microwire Serial
EEPROM
NOT Recommended for New Designs:
Replace with CAT93C86B
Description
The CAT93C86 is a 16 Kb 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
ON Semiconductor’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.

, the x16 organization
is selected. When it is connected to ground, the x8 pin is selected. If
the ORG pin is left unconnected, then an internal pull−up device will
select the x16 organization.
