DESCRIPTION
The M40Z300/W NVRAM Con troller is a self-con­tained device which converts a standard low-pow­er SRAM into a non-volatile memory. A precision voltage reference and comparator monitors the V
CC
input for an out-of-tolerance condition.

When an invalid VCC condition occurs, t he condi­tioned chip enable outputs (E1
CON
to E4
CON
) are forced inactive to write-protect the st ored data in the SRAM. During a power failure, the SRAM is switched from the V
CC
pin to the lithium cell within the SNAPHAT to provide the energy required for data retention. On a subsequent power-up, the SRAM remains write protect ed until a valid power condition returns.
The 28 pin, 330 mil SOIC provides sockets with gold plated contacts for direct connection to a sep­arate 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 im­proper insertion. This unique design allows the SNAPHAT battery p acka ge t o b e m ount ed o n t op of the SOIC package after the c ompletion of the surface mount process which greatly reduces the board manufacturing process complexity of either directly soldering or inserting a battery into a sol­dered holder. Providing non-volatility becomes a "SNAP".
The 16 pin SOIC provides battery pins for an ex­ternal user supplied battery.

OPERATION
The M40Z300/W, as shown in Figure 4, can c on­trol up to four (eight, if placed in parallel) standard low-power SRAMs. These SRAMs must be config­ured 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 conditioned chip enable (E1
CON
to E4
CON
) output
pins follow the chip enable (E
) input pin with timing
shown in Table 7. An internal switch connects V
CC
to V
OUT
.
This switch has a vol tage drop of less than 0.3V (I
OUT1
).
When V
CC
degrades during a power failure,
E1
CON
to E4
CON
are forced inactive inde pendent
of E
. In this situation, the SRAM is unconditionally
write protected as V
CC
falls below an out-of-toler-
ance threshold (V
PFD
). For the M40Z300 the pow-
er fail detection value associated with V
PFD
is selected by the Threshold Select (THS) pin and is shown in Table 6A. For the M 40Z300W, the THS pin selects both the supply vo ltage and V
PFD
as
shown in Table 6B. Note: In either case, THS pi n must b e connected
to either V
SS
or V
OUT
.
If chip enable access is in progress during a power fail detection, that memory cycle continues to com­pletion before the memory is write protected. I f the memory cycle is not terminated within time t
WPT
,
E1
CON
to E4
CON
are unconditionally driven high, write protecting the SRAM. A power failure during a write cycle may corrupt data at the currently ad­dressed location, but does not jeopardize the rest of the SRAM’s contents. At voltages below V
PFD
(min), the user can be assured the memory will be write protected within the Write Protect Time (t
WPT
) provided the VCC fall time exceeds tF (See
Table 7). As V
CC
continues to degrade, the internal switch
disconnects V
CC
and connects the internal battery
to V
OUT
. This occurs at the switchover voltage
(V
SO
). Below the VSO, the battery provides a volt-
age V
OHB
to the SRAM and can supply current
I
OUT2
(see Table 6A/6B).
When V
CC
rises above VSO, V
OUT
is switched
back to the supply voltage. Outputs E1
CON
to
E4
CON
are held inactive for t
CER
(120ms maxi-
mum) after the power supply has reached V
PFD
,
independent of the E
input, to all ow fo r proces sor
stabilization (see Figure 6).

DATA RETENTION LIFETIME CALCULATION
Most low power SRAMs on the market today can be used with the M40Z300/W NVRAM Cont roller. There are, however some criteria which should be used in making the final choice of which S RA M to use. The SRAM must be designed in a way where the chip enable input disables all other inputs to the SRAM. This allows i nputs to the M40Z 300/W and SRAMs to be Don’t Care once V
CC
falls below
V
PFD
(min). The SRAM should also guarantee
data retention down to V
CC
= 2.0V. T he chip en­able 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 V
OUT
.
If data retention lifetime is a critical parameter f or the system, it is importa nt to re view the dat a reten­tion current specifications for the particular SRAMs being evaluated. M ost SRAMs specify a data retention current at 3.0V. Manufacturers gen­erally specify a typical condition for room temper­ature along with a worst case condition (generally at elevated temperatures). The system level re­quirements will determine the choice of which val­ue to use. The data retent ion current val ue of the SRAMs can then be added to t he I
CCDR
value of
the M40Z300/W to de termine the t otal current re­quirements for data retention. The available bat­tery capacity for the SNAPHAT of your choice can then be divided b y this current to determine the amount of data retention available (see Table 8).
CAUTION: Take care to avoid inadvertent dis­charge through V
OUT
and E1
CON
-E4
CON
after bat-
tery has been attached. For a further more detailed review of lifetime cal-
culations, please see Application Note AN1012.

POWER-ON RESET OUTPUT
All microprocessors have a reset input which forc­es them to a known state when starting. The M40Z300/W has a reset output (RST
) pin which is
guaranteed to be low within t
WPT
of V
PFD
(See Ta­ble 7). This signal is an open drain conf iguration. An appropriate pull-up resistor should be chosen to control the rise time. This signal will be valid for all voltage conditions, even when V
CC
equals VSS.
Once V
CC
exceeds the power failure detect volt-
age V
PFD
, an internal timer keeps RST low for
t
REC
to allow the power supply to stabilize.
TWO TO FOUR DECODE
The M40Z300/W includes a 2 input (A, B) decoder which allows the control of up to 4 independent SRAMs. The Truth Table for these inputs is shown in Table 3.

BATTERY LOW PIN
The M40Z300/W automatically performs battery voltage monitoring upon power-up, and at factory­programmed time intervals of at least 24 hours. The Battery Low (BL
) pin will be a sserted if the battery voltage is f ound to be less than approxi­mately 2.5V. The BL
pin will remain asserted until completion of battery replacement and subse­quent 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 se­quence, 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.
If a battery low indication is generated during the 24-hour interval check, this indicates that the bat­tery is near end of life. However, data is not com­promised due to the fact that a nominal V
CC
is supplied. In order to insure data integrity during subsequent periods of bat tery back-up m ode, the battery should be replaced. SNAPHAT top should be replaced with valid V
CC
applied to the device.
The M40Z300/W only monitors the battery when a nominal V
CC
is applied to the device. Thus appli­cations which require extensive durations in the battery back-up mode should be powered-up peri­odically (at least once every few months) in order for this technique to be beneficial. Additionally, if a battery low is indicated, data integrity should be verified upon power-up via a checksum or other technique. The BL
pin is an open drain output and
an appropriate pull-up resistor to V
CC
should be
chosen to control the rise time.

VCC NOISE AND NEGATIVE GOING TRANSIENTS
I
CC
transients, including those produced by output switching, can produce voltage fluctuations, re­sulting in spikes on the V
CC
bus. These transients can be reduced if capacitors are used to store en­ergy, which stabilizes the V
CC
bus. The energy stored in the bypass capacitors will be released as low going spikes are generated or energy will be absorbed when overshoots occur.
A ceramic bypass capacitor value of 0.1µF (as shown in figure 8) is recommended in order to pro­vide the needed filtering.
In addition to transients that are caused by normal SRAM operation, power cycling can generate neg­ative voltage spikes on V
CC
that drive it to values
below V
SS
by as much as one volt. These negative spikes can cause data corruption in the SRAM while in battery backup mode. To protect from these voltage spikes, STMicroelectronics recom­mends connecting a schottky diode from V
CC
to
V
SS
(cathode connected to VCC, anode to VSS). Schottky diode 1N5817 is recommended for through hole and MBRS120T3 is recommended for surface mount.
