The MN6311S is a 2048-bit, bit sequential EEPROM with a built-in address counter. It sequentially increments the address with the clock input to produce serial output. It includes a built-in charge pump circuit and timer for automatically erasing, writing, and modifying data using only a single 3 volt power supply. To reduce write times, it includes a block write function for writing up to 32 bits at a time. This function makes it possible to rewrite the contents of all 2048 bits within 1 second (typ.).
