MR0A08B 128K x 8 MRAM FEATURES 3.3 Volt power supply Fast 35 ns read/write cycle SRAM compatible timing Native non-volatility Unlimited read & write endurance 48-ball FBGA Data always non-volatile for >20 years at temperature Commercial and industrial temperatures All products meet MSL-3 moisture sensitivity level RoHS-Compliant TSOP2 and BGA packages BENEFITS 44-pin TSOP2 One memory replaces FLASH, SRAM, EEPROM and MRAM in system for simpler, more efficient design Improves reliability by replacing battery-backed SRAM INTRODUCTION The MR0A08B is a 1,048,576-bit magnetoresistive random access memory (MRAM) device organized as 131,072 words of 8 bits. The RoHS MR0A08B offers SRAM compatible 35 ns read/write timing with unlim - ited endurance. Data is always non-volatile for greater than 20-years. Data is automatically protected on power loss by low-voltage inhibit circuitry to prevent writes with voltage out of specification. The MR0A08B is the ideal memory solution for applications that must permanently store and retrieve critical data and programs quickly. The MR0A08B is available in small footprint 400-mil, 44-lead plastic small-outline TSOP type-2 package, 8 mm x 8 mm, or a 48-pin ball grid array (BGA) package with 0.75 mm ball centers. (The 32-SOIC package options is obsolete and no longer available for new orders.) These packages are compatible with similar low-power SRAM products and other non-vola- tile RAM products. The MR0A08B provides highly reliable data storage over a wide range of temperatures. The product is offered with commercial temperature range (0 to +70 C) and industrial tempera - ture range (-40 to +85 C).
