INTRODUCTION

The MR0D08B is a dual power supply 1,048,576-bit magnetoresistive random access memory (MRAM) de-

vice organized as 131,072 words of 8 bits. It supports I/O voltages from +1.65 to +3.6 volts. The MR0D08B

offers SRAM compatible 45ns 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 pre-

vent writes with voltage out of specification. The MR0D08B is the ideal memory solution for applications

that must permanently store and retrieve critical data and programs quickly.

The MR0D08B is available in small footprint 8 mm x 8 mm, 48-pin ball grid array (BGA) package with 0.75

mm ball centers.

The MR0D08B provides highly reliable data storage over a wide range of temperatures. The product is of-

fered with commercial temperature (0 to +70 °C).
