256 Mbit parallel NOR Flash in 56-TSOP
The Micron MT28EW256ABA1LJS-0SIT is a 256 Mbit parallel NOR Flash memory in a 56-TSOP surface-mount package. It is organized as 32 M x 8 or 16 M x 16, and operates from a 2.7 V to 3.6 V supply. The parallel interface provides direct random access for execute-in-place (XIP) code storage, with a 75 ns access time and a 60 ns write cycle time per word or page. Rated for the -40°C to 85°C industrial temperature range, it is suited for embedded systems requiring reliable non-volatile code storage in outdoor telecom, factory automation, and motor-drive environments.
