MN63121

The MN63121 is a 1K-bit EEPROM supporting serial I/O and operating on a single power supply with a voltage between 1.8 and 5.5 V. MN63121 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 updateoperations.

The memory organization is 64 ´ 16 bits. The MN63121 chip indicates the end of a write operation with either the RDY/ BUSY pin or the state of the DO pin after the status output 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.
