The 28 pin, 330 mil SOIC provides sockets with
gold plated contacts for direct connection to a sep-
arate SNAPHAT housing containing the battery.
The SNAPHAT housing has gold plated pins
which mate with the sockets, ensuring reliable
connection. The housing is keyed to prevent im-
proper insertion. This unique design allows the
SNAPHAT battery package to be mounted on top
of the SOIC package after the completion of the
surface mount process which greatly reduces the
board manufacturing process complexity of either
directly soldering or inserting a battery into a sol-
dered holder. Providing non-volatility becomes a
"SNAP".

OPERATION
If chip enable access is in progress during a power
fail detection, that memory cycle continues to com-
pletion before the memory is write protected. If the
The M40Z300/W, as shown in Figure 4, can con-
trol up to four (eight, if placed in parallel) standard
low-power SRAMs. These SRAMs must be config-
ured to have the chip enable input disable all other
input signals. Most slow, low-power SRAMs are
configured like this, however many fast SRAMs
are not. During normal operating conditions, the

DATA RETENTION LIFETIME CALCULATION
Most low power SRAMs on the market today can
be used with the M40Z300/W NVRAM Controller.
There are, however some criteria which should be
used in making the final choice of which SRAM to
use. The SRAM must be designed in a way where
the chip enable input disables all other inputs to
the SRAM. This allows inputs to the M40Z300/W

data retention down to V

able access time must be sufficient to meet the
system needs with the chip enable propagation
delays included. If the SRAM includes a second
Chip Enable pin (E2), this pin should be tied to
the M40Z300/W to determine the total current re-
quirements for data retention. The available bat-
tery capacity for the SNAPHAT of your choice can
then be divided by this current to determine the
amount of data retention available (see Table 8).

OUT
If data retention lifetime is a critical parameter for
the system, it is important to review the data reten-
tion current specifications for the particular
SRAMs being evaluated. Most SRAMs specify a
data retention current at 3.0V. Manufacturers gen-
erally specify a typical condition for room temper-
ature along with a worst case condition (generally
at elevated temperatures). The system level re-
quirements will determine the choice of which val-
ue to use. The data retention current value of the

The M40Z300/W automatically performs battery
voltage monitoring upon power-up, and at factory-
programmed time intervals of at least 24 hours.
The Battery Low (BL) pin will be asserted if the
battery voltage is found to be less than approxi-
mately 2.5V. The BL pin will remain asserted until
completion of battery replacement and subse-
quent battery low monitoring tests, either during
the next power-up sequence or the next scheduled
24-hour interval.
If a battery low is generated during a power-up se-
quence, this indicates that the battery is below
2.5V and may not be able to maintain data integrity
in the SRAM. Data should be considered suspect,
and verified as correct. A fresh battery should be
installed.

Note: 1. The SOIC package (SOH28) requires the battery package (SNAPHAT) which is ordered separately under the part number
“M4Zxx-BR00SH1" in plastic tube or "M4Zxx-BR00SH1TR" in Tape & Reel form.
2. Delivery may include either the 2-pin version of the SOIC/SNAPHAT or the 4-pin version of the SOIC/SNAPHAT. Both are function-
ally equivalent (see package drawing section for details).
Caution: Do not place the SNAPHAT battery package "M4Zxx-BR00SH1" in conductive foam since will drain the lithium button-cell battery.
For a list of available options (Speed, Package, etc...) or for further information on any aspect of this de-
vice, please contact the ST Sales Office nearest to you.
