Introduction

The MR1A16A is a 2,097,152-bit magnetoresistive random access memory (MRAM) device organized as

131,072 words of 16 bits. The MR1A16A offers SRAM compatible 35 ns read/write timing with

unlimited endurance. Data is always non-volatile for greater than 20-years. Data is automatically

protected on power loss by low-voltage inhibit circuitry to prevent writes with voltage out of

specification. The MR1A16A is the ideal memory solution for applications that must permanently store

and retrieve critical data and programs quickly.

The MR1A16A is available in small footprint 400-mil, 44-lead plastic small-outline TSOP type-II package

or 8 mm x 8 mm, 48-pin ball grid array (BGA) package with 0.75 mm ball centers. These packages are

compatible with similar low-power SRAM products and other non-volatile RAM products.

The MR1A16A provides highly reliable data storage over a wide range of temperatures. The product is

∘

offered with commercial temperature (0 to +70 C), industrial temperature (-40 to +85 C), and

∘

extended temperature (-40 to +105 C) range options.

Electrical Specifications

Absolute Maximum Ratings

This device contains circuitry to protect the inputs against damage caused by high static voltages or

electric fields; however, it is advised that normal precautions be taken to avoid application of any

voltage greater than maximum rated voltages to these high-impedance (Hi-Z) circuits.

The device also contains protection against external magnetic fields. Precautions should be taken

to avoid application of any magnetic field more intense than the maximum field intensity specified

in the maximum ratings.

Power Up and Power Down Sequencing

MRAM is protected from write operations whenever V

is less than V

. As soon as V

exceeds V

DDmin

, there is a startup time of 2 ms before read or write operations can start.

This time allows memory power supplies to stabilize. The /E and /W control signals should

track V

on power up to V

-0.2v or V

(whichever is lower) and remain high for the

startup time. In most systems, this means that these signals should be pulled up with a

resistor so that signal remains high if the driving signal is Hi-Z during power up. Any logic

that drives /E and /W should hold the signals high with a power-on reset signal for longer

than the startup time. During power loss or brownout where V

goes below V

, writes are

protected and a startup time must be observed when power returns above V

DDmin
