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.
