INTRODUCTION
The MR0A08B is a 1,048,576-bit magnetoresistive random access
memory (MRAM) device organized as 131,072 words of 8 bits. The
MR0A08B offers SRAM compatible 35 ns read/write timing with unlim-
ited endurance.
RoHS
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 (The 32-SOIC package options is obsolete and no longer available for new orders.)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).

ELECTRICAL SPECIFICATIONS
Absolute Maximum Ratings
This device contains circuitry to protect the inputs against damage caused by high static voltages or electric
fields; 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 fields. Precautions should be taken o avoid
application of any magnetic field more intense than the maximum field intensity specified in the maximum
1
ratings.

2. All voltages are referenced to V .

Power Up and Power Down Sequencing
The MRAM is protected from write operations whenever V is less than V . As soon as V exceeds
DD
WI
DD
V
(min), there is a startup time of 2 ms before read or write operations can start. This time allows memory
DD
power supplies to stabilize.
The E and W control signals should track V on power up to V - 0.2 V or V (whichever is lower) and
DD
DD
IH
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 V goes below V , writes are protected and a startup time must be
DD
WI
observed when power returns above V (min).

1. All write occurs during the overlap of E low and W low. Power supplies must be properly grounded and decoupled and bus
contention conditions must be minimized or eliminated during read and write cycles. If G goes low at the same time or after
W goes low, the output will remain in a high impedance state. After W or E has been brought high, the signal must remain
in steady-state high for a minimum of 2 ns. The minimum time between E being asserted low in one cycle to E being as-
serted low in a subsequent cycle is the same as the minimum cycle time allowed for the device.
2. All write cycle timings are referenced from the last valid address to the first transition address.

1. All write occurs during the overlap of E low and W low. Power supplies must be properly grounded and decoupled and bus
contention conditions must be minimized or eliminated during read and write cycles. If G goes low at the same time or
after W goes low, the output will remain in a high impedance state. After W or E has been brought high, the signal must re-
main in steady-state high for a minimum of 2 ns. The minimum time between E being asserted low in one cycle to E being
asserted low in a subsequent cycle is the same as the minimum cycle time allowed for the device.
2. All write cycle timings are referenced from the last valid address to the first transition address.
3. If E goes low at the same time or after W goes low, the output will remain in a high-impedance state. If E goes high at the
same time or before W goes high, the output will remain in a high-impedance state.

Notes:
1. All write occurs during the overlap of E low and W low. Power supplies must be properly grounded and decoupled and bus
contention conditions must be minimized or eliminated during read and write cycles. If G goes low at the same time or
after W goes low, the output will remain in a high impedance state. After W, or E has been brought high, the signal must re-
main in steady-state high for a minimum of 2 ns. The minimum time between E being asserted low in one cycle to E being
asserted low in a subsequent cycle is the same as the minimum cycle time allowed for the device.
2. All write cycle timings are referenced from the last valid address to the first transition address.
3. If E goes low at the same time or after W goes low the output will remain in a high impedance state. If E goes high at the
same time or before W goes high the output will remain in a high impedance state. E must be brought high each cycle.
