Introduction

The MR0A16A is a 1,048,576-bit magnetoresistive

random access memory (MRAM) device

organized as 65,536 words of 16 bits. The

MR0A16A is equipped with chip enable (E), write

enable (W), and output enable (G) pins, allowing

for significant system design flexibility without bus

contention. Because the MR0A16A has separate

byte-enable controls (LB and UB), individual bytes

can be written and read.

MRAM is a nonvolatile memory technology that

protects data in the event of power loss and does

not require periodic refreshing. The MR0A16A is

the ideal memory solution for applications that

must permanently store and retrieve critical data

quickly.

The MR0A16A is available in a 400-mil, 44-lead

plastic small-outline TSOP type-II package with an

industry-standard center power and ground SRAM

pinout.

The MR0A16A is available in Commercial (0˚C to
