MN63121
1K-Bit EEPROM
Overview
The MN63121 is a 1K-bit EEPROM supporting serial
I/O and operating on a single power supply with a volt-
age between 1.8 and 5.5 V. It provides the following pins
for easy interfacing to microprocessors or
microcontrollers: chip select (CS), serial clock (SCK),
data input (DI), data output (DO), reset (RESET), and
busy (RDY/BUSY). It includes a built-in timer for use in
automatically erasing and writing data during data up-
date operations.
The memory organization is 64 × 16 bits. The chip in-
dicates the end of a write operation with either the RDY/
BUSY pin or the state of the DO pin after the status out-
put mode has been set.
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 10⁵ write cycles.
