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

extended temperature (-40 to +105

... MRAM is protected from write operations whenever V exceeds V , there is a startup time before read or write operations can start. DDmin This time allows memory power supplies to stabilize. The /E and /W control signals should track V on power 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 ...
