1.0 INTRODUCTION
The Aeroflex 64Megabit Non-Volatile magnetoresistive random access memory (MRAM) is a high-
performance memory multichip module (MCM) compatible with traditional asynchronous SRAM
operations, organized as four individual 16,777,216 words by 8 bits. The MRAM is equipped with five
chip enables (/En), a single write enable (/W), and a single output enable (/G) pin, allowing for significant
system design flexibility without bus contention. Data is non-volatile for > 15 years at temperature and
data is automatically protected against power loss by a low voltage write inhibit.
The UT8MR8M8-EVB allows the user access to most all the features of the 64Mb MRAM via bench top
evaluation or using the UT699 LEON-3FT evaluation board.
2.0 SCOPE
This document describes the features and necessary steps to set-up and operate the Aeroflex Colorado Springs
64Megabit Non-Volatile MRAM Evaluation Board. Users must be familiar with the UT699 LEON-3FT Processor
and the 64Megabit Non-Volatile MRAM datasheets.
