MN63112S
MN63112S is 2K-Bit EEPROM manufactured by Panasonic.
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 VCC. 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 105 write cycles.
