MN63121 1K-Bit EEPROM Overview Pin Assignment 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
CS VCC
fo sy ac ing mic rop roces so microcontrollers: chip select (CS), serial clock (SCK), SCK RDY/BUSY data input (DI), data output (DO), reset (RESET), and busy (RDY/BUSY). It includes a built-in timer for use in DI RESET automatically erasing and writing data during data up- date operations. DO GND The memory organization is 64 × 16 bits. The chip in- dicates the end of a write operation with either the RDY/
