M48Z35, M48Z35Y
The M48Z35/35Y is a non-volatile pin and function equivalent to any JEDEC standard 32K x8 SRAM. It also easily fits into many ROM, EPROM, and EEPROM sockets, providing the non-volatility of PROMs without any requirement for special write timing or limitations on the n umber of writes that can be performed. The 28 pin 600mil DIP
CAPHAT™ houses the M48Z35/35Y silicon with a long life lithium button cell in a single package.
The 28 pin 330mil SOIC provides sockets with gold plated contacts at both ends for direct con-
nection to a separate SNAPHAT housing cont ain­ing the battery. The 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. Insertion of the SNAPHAT housing after reflow prevents potential battery damage due to the high temperatures required for device surface-mounting. The SNAPH AT housing is keyed to prevent reverse insertion.

The SOIC and battery packages are shipped sep­arately in plastic anti-static tubes or in Tape & Reel form.
For the 28 lead SOIC, the battery package (i.e. SNAPHAT) part number is "M4Z28-BR00SH1".
The M48Z35/35Y also has its own Power-fail De­tect circuit. The control circuitry constantly moni­tors the single 5V supply for an out of tolerance condition. When V
CC
is out of tolerance, the circuit write protects the S RAM, p roviding a high degree of data security in the midst of unpredictable s ys­tem operation brought on by low V
CC
. As VCC falls below approximately 3V, the control circuitry con­nects the battery which maintains data until valid power returns.
READ MODE
The M48Z35/35Y is in the Read Mode whenever W
(Write Enable) is high, E (Chip Enable) is low. The device architecture allows ripple-through ac­cess of data from eight of 264,144 locations in the static storage array. Thus, the unique address specified by the 15 Address Inputs defines which one of the 32,768 bytes of data is to be accessed. Valid data will be available at the Data I/O pins within Address Access time (t
AVQV
) after the last address input signal is stable, providing that the E and G access times are also satisfied. If the E and G
access times are not met, valid data will be available after the latter of the Chip Enable Access time (t
ELQV
) or Output Enable Access time
(t
GLQV
).
The state of the eight three-s tate Da ta I/O si gnals is controlled by E
and G. If the outputs are activat-
ed before t
AVQV
, the data lines will be driven to an
indeterminate state until t
AVQV
. If the Ad dres s In-
puts are changed while E
and G remain active, output dat a will rem ain v alid for Outp ut Dat a Hold time (t
AXQX
) but will go indeterminate until the next
Addr e ss Access.
WRITE MODE
The M48Z35/35Y is in the Write Mode whenever W
and E are low. The start of a write is referenced
from the latter occurring f alling edge of W
or E. A write is terminated by the earlier rising edge of W or E. The addresses must be held valid throughout the cycle. E
or W must return high for a minimum
of t
EHAX
from Chip Enable or t
WHAX
from Write En­able prior to the initiation of another read or write cycle. Data -in must be vali d t
DVWH
prior to the end
of write and remain valid for t
WHDX
afterward. G should be kept high during write cycles to avoid bus contention; although, if the output bus has been activated by a low on E
and G, a low on W
will disab le the ou t pu t s t
WLQZ
after W falls.

DATA RETENTION MODE
With valid V
CC
applied, the M48Z35/35Y operates as a conventional BYTEWIDE™ static RAM. Should the supply voltage decay, the RAM will au­tomatically power-fail deselect, write protecting it­self when V
CC
falls within the V
PFD
(max),
V
PFD
(min) window. All outputs become high im-
pedance, and all inputs are treated as "don't care." Note: A power failure during a write cycle may cor-
rupt data at the currently addressed location, but does not jeopardize the rest of the RAM's content. At voltage s below V
PFD
(min), the user can be as­sured the memory will be in a write protected state, provided the V
CC
fall time is not less than tF. The M48Z35/35Y may respond to transient noise spikes on V
CC
that reach into the deselect window
during the time the device is sampling V
CC
. There-
fore, decoupling of the power supply lines is rec­ommended.
When V
CC
drops below VSO, the control circuit switches power to the internal battery which pre­serves data. The internal button cell will maintain data in the M48Z35/35Y for an accumulate d peri­od of at least 10 years (at 25°C) when V
CC
is less
than V
SO
.
As system power returns and V
CC
rises above
V
SO
, the battery is disconn ected, and the power
supply is switched to external V
CC
. Write protec-
tion continues until V
CC
reaches V
PFD
(min) plus
t
REC
(min). Normal RAM operation can resume
t
REC
after VCC exceeds V
PFD
(max).

POWER SUPPLY DECOUPLING and UNDERSHOOT PROTECTION
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 by-
pass capacitor value of 0.1µF (as shown in Figure
9) 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 VCC 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, it is recommended to con­nect a schottky diode from V
CC
to VSS (cathode
connected to V
CC
, anode to VSS). Schottky diode 1N5817 is recommended for through hole and MBRS120T3 is recommended for surface mount.

3. 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 equival ent (see package drawing section for details).
4. Industrial temperature grade available in SOIC package (SOH28) only.
Caution: Do not pl ace the SNAPHAT batt ery packa ge "M4Z28-B R00SH1" in conductive foam sinc e will drain the lithium but ton-cell battery.
