The MR256A08B offers SRAM compatible 35ns read/write timing with unlimited 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 MR256A08B is the ideal memory solution for applications that must permanently store and retrieve critical data and programs quickly. The MR256A08B is available in a small footprint 400-mil, 44-lead plastic small-outline TSOP type-2 package, or an 8 mm x 8 mm, 48-pin ball grid array (BGA) package. (The 32-SOIC package options is obsolete and no longer available for new orders.) All package footprints are compatible with similar low-power SRAM products and other non-volatile RAM products. The MR256A08B 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) range options.

The device also contains protection against external magnetic fields. Precautions should be taken to avoid application of any magnetic field more intense than the maximum field intensity specified in the maximum ratings. 1 Table 3 - Absolute Maximum Ratings Parameter Symbol VDD Supply voltage 2 Value Unit -0.5 to 4.0 V Voltage on an pin 2 VIN -0.5 to VDD + 0.5 V Output current per pin IOUT 20 mA Package power dissipation 3 PD 0.600 W -10 to 85 C Temperature under bias MR256A08B (Commercial) MR256A08BC (Industrial) TBIAS -45 to 95 Storage Temperature Tstg -55 to 150 C Lead temperature during solder (3 minute max) TLead 260 C Maximum magnetic field during write Hmax_write 2000 A/m Maximum magnetic field during read or standby Hmax_read 8000 A/m Notes: 1. Permanent device damage may occur if absolute maximum ratings are exceeded. Functional operation should be restricted to recommended operating conditions. Exposure to excessive voltages or magnetic fields could affect device reliability. 2. All voltages are referenced to VSS. 3. Power dissipation capability depends on package characteristics and use environment.

There is a 2 ms startup time once VDD exceeds VDD,(min). See "Power Up and Power Down Sequencing Timing Diagram". 2. VIH(max) = VDD + 0.3 VDC ; VIH(max) = VDD + 2.0 VAC (pulse width 10 ns) for I 20.0 mA. 3. VIL(min) = -0.5 VDC ; VIL(min) = -2.0 VAC (pulse width 10 ns) for I 20.0 mA. Copyright (c) 2018 Everspin Technologies 7 MR256A08B Rev. 6.5 3/2018 MR256A08B Power Up and Power Down Sequencing The MRAM is protected from write operations whenever VDD is less than VWI. As soon as VDD exceeds VDD(min), there is a startup time of 2 ms before read or write operations can start. This time allows memory power supplies to stabilize. The E and W control signals should track VDD on power up to VDD- 0.2 V or VIH (whichever is lower) and remain high for the startup time. In most systems, this means that these signals should be pulled up with a resistor so that signal remains high if the driving signal is Hi-Z during power up. Any logic that drives E and W should hold the signals high with a power-on reset signal for longer than the startup time. During power loss or brownout where VDD goes below VWI, writes are protected and a startup time must be observed when power returns above VDD(min).
