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
ALOGEN ^FR
LEA _{D F REETM}
I Sequential read
I Program enable (PE) pin
I 1,000,000 Program/erase cycles
I 100 year data retention
I Commercial, industrial and automotive
temperature ranges
I RoHS-compliant packages
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.

Note: When the ORG pin is connected to VCC, the x16 organiza-
tion is selected. When it is connected to ground, the x8 pin is
selected. If the ORG pin is left unconnected, then an internal pullup
device will select the x16 organization.
