PIN CONFIGURATION
DIP Package (P, L)
SOIC Package (J,W)
CMOS EEPROM floating gate technology. The devices
are designed to endure 1,000,000 program/erase cycles
and have a data retention of 100 years. The devices are
available in 8-pin DIP, 8-pin SOIC or 8-pin TSSOP
packages.
DESCRIPTION

C46/56/57/66/86 are 1K/2K/2K/4K/16K-bit
Serial EEPROM memory devices which are 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 93
L
C46/56/

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.
