Panasonic MN61113S, MN61113 Datasheet
EEPROMs
MN61113, MN61113S
2K-Bit EEPROMs
Overview
The MN61113 and MN61113S are 2048-bit, bit sequential EEPROMs with built-in address counters. They sequentially increment the address with the clock input to
produce serial output.
They include 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, they include 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.).
