INTRODUCTION
The MR4A16B is a 16,777,216-bit magnetoresistive random access memory
(MRAM) device organized as 1,048,576 words of 16 bits. The MR4A16B oers
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 specication. 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
oered with commercial temperature (0 to +70 °C), and industrial temperature (-40 to +85 °C) operating
temperature options.

2. ELECTRICAL SPECIFICATIONS
Absolute Maximum Ratings
This device contains circuitry to protect the inputs against damage caused by high static voltages or
electric elds; however, it is advised that normal precautions be taken to avoid application of any
voltage greater than maximum rated voltages to these high-impedance (Hi-Z) circuits.
The device also contains protection against external magnetic elds. Precautions should be taken
to avoid application of any magnetic eld greater than the maximum eld intensity specied
in the maximum ratings.

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
elds could aect device reliability.
2 All voltages are referenced to VSS. The DC value of VIN must not exceed actual applied VDD by more than
0.5V. The AC value of VIN must not exceed applied VDD by more than 2V for 10ns with IIN limited to less than
20mA.
3 Power dissipation capability depends on package characteristics and use environment.

1 There is a 2 ms startup time once VDD exceeds VDD,(min). See Power Up and Power Down Sequencing below.
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.
Table 2.2 Operating Conditions
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 resis-
tor so that a 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).
