MRAM - SPI

General Description

The device is a Spin-Transfer-Torque Magneto-resistive Random Access Memory (STT-MRAM). It features a SPI bus interface, XIP(execute-in-place) functionality, and hardware/software-based data protection mechanisms. SPI (Serial Peripheral Interface) is a synchronous serial communication interface with command, address and data signals. It requires fewer pin counts than parallel interface and is easy to be configured on the system. The device can replace Flash, FRAM or (nv)SRAM with same functionality and non-volatility.

 Features

Supports Serial Peripheral Interface with Mode 0 and Mode 3- Single SPI (1-1-1, 1-1-2, 1-2-2, 1-1-4, 1-4-4) - Dual SPI (2-2-2) - Quad SPI (4-4-4)
