General Description

The M50FW016 is a 16 Mbit (2Mb x8) non-volatile memory that can be read, erased and reprogrammed.

These operations can be performed using a single low voltage (3.0 to 3.6V) supply.

For fast programming and fast erasing, an optional 12V power supply can be used to reduce the programming and the erasing times.

Key Features

  • e pins do not have assigned functions in this revision of the part.
