M29W160EB70N6

 Product Overview

The M29W160EB70N6 is a high-speed, low-power, 16-Mbit (16-megabit) parallel NOR Flash memory . It is a non-volatile memory that retains stored information even when power is removed, and it can be read, erased, and reprogrammed in-system . The device is organized as either 2M x 8 bits (byte-wide) or 1M x 16 bits (word-wide) to provide flexibility for different data bus widths . The "EB" in the part number denotes a Bottom Boot Block architecture, where the boot block sector is located at the lowest memory addresses . This is ideal for systems that require the boot code to reside in a protected, reliable memory region.
