MR20H40 - 4Mb SPI Interface MRAM

General Description

MR2xH40 is a family of 4,194,304-bit magnetoresistive random access memory (MRAM) devices organized as 524,288 words of 8 bits.

They are the ideal memory solution for applications that must store and retrieve data and programs quickly using a small number of I/O pins.

Key Features

  •   No write delays.
  •   Unlimited write endurance.
  •   Data retention greater than 20 years.
  •   Automatic data protection on power loss.
  •   Fast, simple SPI interface, up to 50 MHz clock rate with MR20H40.
  •   3.0 to 3.6 Volt power supply range.
  •   Low-current sleep mode.
  •   Industrial (-40 to 85°C), Extended (-40 to 105°C), and AEC-Q100 Grade 1 (-40 to 125°C) temperature range options.
  •   Available in 8-pin DFN or 8-pin DFN Small Fl.
