for Execute in Place (XIP) operation.

• MSL Level 3.

16-SOIC

24-BGA

DESCRIPTION

The MR10Q010 is the ideal memory solution for applications that must store and retrieve data and programs quickly

using a small number of pins, low power, and choice of a 24-ball BGA or a 16-pin SOIC package. The four I/O’s in Quad

SPI mode allow very fast reads and writes, making it an attractive alternative to conventional parallel data bus inter-

faces in next generation RAID controllers, server system logs, storage device buffers, and embedded system data and

program memory.

Using Everspin’s patented MRAM technology, both reads and writes can occur randomly in memory with no delay

between writes.

Standard Serial Peripheral Interface (SPI), Quad SPI and Quad Peripheral Interface (QPI) modes are supported at a clock

rate up to 104MHz. XIP operation is supported for Read commands in all three modes.

The MR10Q010 Quad SPI MRAM is organized as 131,072 words of 8 bits.
