MN63112S
2K-Bit EEPROM
Overview
The MN63112S is a 2K-bit EEPROM supporting se-
rial I/O and operating on a single power supply with a
voltage between 1.8 and 5.5 V. It provides the following
pins for easy interfacing to microprocessors or
microcontrollers: chip select (CS), serial clock (SK), data
input (DI), and data output (DO). It includes a built-in
timer for use in automatically erasing and writing data
during data update operations.
The ORG pin provides a choice of two memory orga-
nizations: 256
脳
8 bits when ORG is connected to ground
and 128
脳
16 bits when ORG is connected to V
CC
. An
internal pull-up resistor makes the latter the default con-
figuration.
Conversion of peripheral circuits to CMOS realizes
great reductions in power consumption. Use of floating
gate memory cells and a built-in error correction circuit
ensures reliable operation for 10
5
write cycles.
