General Description

The M50LPW080 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

  • n of the Top Block (Block 15). Write Protect, WP, must be set prior to a Program or B.
