High Performance M1004204/M1008204/M1016204 Serial MRAM Memory M3004204/M3008204/M3016204 Description Features Mxxxx204 is a magneto-resistive random-access memory Interface (MRAM). It is offered in density ranging from 4Mbit to 16Mbit. Serial Peripheral Interface QSPI (4-4-4) MRAM technology is analogous to Flash technology with SRAM Single Data Rate Mode: 108MHz compatible read/write timings (Persistent SRAM, P-SRAM). Data is Double Data Rate Mode: 54MHz always non-volatile. Technology 40nm pMTJ STT-MRAM MRAM is a true random-access memory allowing both reads and writes to occur randomly in memory. MRAM is ideal for applications Virtually unlimited Endurance and Data Retention (see that must store and retrieve data without incurring large latency Endurance and Data Retention specification on page 38) penalties. It offers low latency, low power, virtually infinite Density endurance and retention, and scalable non-volatile memory 4Mb, 8Mb, 16Mb technology. Operating Voltage Range VCC: 1.71V 2.00V Mxxxx204 is available in small footprint 8-pad DFN (WSON) and 8- VCC: 2.70V 3.60V pin SOIC packages. These packages are compatible with similar low-power volatile and non-volatile products. Operating Temperature Range Industrial: -40C to 85C Mxxxx204 is offered with industrial (-40C to 85C) and industrial Industrial Plus: -40C to 105C plus (-40C to 105C) operating temperature ranges. Packages 8-pad DFN (WSON) (5.0mm x 6.0mm) 8-pin SOIC (5.2mm x 5.2mm) Typical Applications Data Protection Ideal for applications that must store and retrieve data Hardware Based: Write Protect Pin (WP ) without incurring large latency penalties.
