MR4A16B 1M x 16 MRAM FEATURES +3.3 Volt power supply Fast 35 ns read/write cycle SRAM compatible timing Unlimited read & write endurance Data always non-volatile for >20 years at temperature RoHS-compliant small footprint BGA and TSOP2 package All products meet MSL-3 moisture sensitivity level BENEFITS One memory replaces FLASH, SRAM, EEPROM and BBSRAM in systems for simpler, more efficient designs Improves reliability by replacing battery-backed SRAM INTRODUCTION The MR4A16B is a 16,777,216-bit magnetoresistive random access memory RoHS (MRAM) device organized as 1,048,576 words of 16 bits. The MR4A16B offers SRAM compatible 35 ns read/write timing with unlimited endurance. Data is always non-volatile for greater than 20 years. Data is automatically pro- tected on power loss by low-voltage inhibit circuitry to prevent writes with voltage out of specification. To simplify fault tolerant design, the MR4A16B includes internal single bit error correction code with 7 ECC parity bits for every 64 data bits. The MR4A16B is the ideal memory solution for applications that must permanently store and retrieve critical data and programs quickly. The MR4A16B is available in a small footprint 48-pin ball grid array (BGA) package and a 54-pin thin small outline package (TSOP Type 2). These packages are compatible with similar low-power SRAM products and other nonvolatile RAM products. The MR4A16B provides highly reliable data storage over a wide range of temperatures. The product is offered with commercial temperature (0 to +70 C), and industrial temperature (-40 to +85 C) operating temperature options. CONTENTS 1.
