General Description

The M50FW080 is a 8 Mbit (1Mb 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 in production lines an optional 12V power supply can be used to reduce the programming and the erasing times.

Key Features

  • e stress ratings only and operation of the device at these or any other conditions above those indicated in the.
