MN63112S
2K-Bit EEPROM
Overview
The MN63112S is a 2K-bit EEPROM supporting serial 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 organizations: 256 × 8 bits when ORG is connected to ground
and 128 × 16 bits when ORG is connected to V
CC
. An
internal pull-up resistor makes the latter the default configuration.
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.
