PIN CONFIGURATION

DIP Package (P, L)

SOIC Package (J,W)

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,

8-pin TSSOP and 8-pad TDFN packages.

DESCRIPTION

The CAT93C86 is a 16K-bit Serial EEPROM memory

device which is configured as either registers of 16 bits

register can be written (or read) serially by using the

DI (or DO) pin. The CAT93C86 is manufactured using

SOIC Package (S,V)

SOIC Package (K,X)

FUNCTIONAL SYMBOL

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.
