UT8MR8M8-EVB 64Megabit Non-
Volatile MRAM Evaluation Board
User Manual
July 2012
www.aeroflex.com/memories
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.

5.0 FEATURES AND GENERAL OPERATION
The Aeroflex 64Megabit Non-Volatile MRAM Evaluation Board provides the user with a flexible means to
configure, control, access, and read/write data to the UT8MR8M8 device. Power to the board may be provided
through the J9 connector on the GR-UT699 CPCI Development Board or through the 100 mil connector J8 on the
UT8MR8M8-EVB. Only one power source should be used at a time.
5.1 Power
5.1.1 External Power
Power to the UT8MR8M8-EVB may be provided externally using 3.3V if using in a bench top only
configuration.
Figure 2. External Power Jumper Configuration Settings

5.1.2 Aeroflex Gaisler Board Power
Power to the UT8MR8M8-EVB is also provided from the J9 connector on the GR-CPCI-UT699 LEON3-
FT CPCI Development Board. J7, the 120 pin connector, is located on the back side of the EVB.
Use caution when mating the 64Megabit Non-Volatile MRAM Evaluation Board to the LEON-3FT
evaluation board. Ensure that the mating connectors are lined up and that the power is removed from the
GR-cPCI-UT699 eval board prior to plugging in the MRAM evaluation board.

5.7 Deep Sleep Power Down (ZZ)
ZZ controls the sleep mode operation. Enabling sleep mode causes all other inputs to be do not cares. ZZ
places all die into internal low power even while system power is still applied to VDD. Pin 12 on the
UT8MR8M8 are routed to a three pin header J2. The center pin on the three pin J2 header is tied to the ZZ
pin, the other pins are tied to VDD and VSS. Please refer to the UT8MR8M8 datasheet for further
information.

The open drain MBE pin drives low when ECC logic detects two bit errors during the current read cycle. It
allows for wired-or of multiple MBE signals when using multiple MRAMs. The MBE signal is routed to
the one pin J6 header. This pin can be monitored if the user chooses to do so.
