MN6311S
2K-Bit EEPROM
Overview
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.).
