for simpler, more eﬃcient designs

RoHS

• Improves reliability by replacing battery-backed SRAM

INTRODUCTION

The MR256DL08B is a 262,144-bit magnetoresistive random access memory (MRAM) device organized as

32,768 words of 8 bits. It supports I/O voltages from +1.65 to +3.6 volts. The MR256DL08B 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 prevent writes

with voltage out of speciﬁcation. The MR256DL08B is the ideal memory solution for applications that

must permanently store and retrieve critical data and programs quickly.

The MR256DL08B is available in small footprint 8 mm x 8 mm, 48-pin ball grid array (BGA) package with

0.75 mm ball centers.

The MR256DL08B provides highly reliable data storage over a wide range of temperatures. The product is

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