Features
■
Integrated, ultra low power SRAM, power-fail
control circuit, and battery
■
Conventional SRAM operation; unlimited
WRITE cycles
■
10 years of data retention in the absence of
power
■
Automatic power-fail chip deselect and WRITE
protection
■
Two WRITE Protect voltages:

■
Battery internally isolated until power is applied
■
Pin and function compatible with JEDEC
standard 512K x 8 SRAMs
■
SOIC package provides direct connection for a
SNAPHAT top which contains the battery
■
SNAPHAT housing (battery) is replaceable
■
Equivalent Surface-Mount (SMT) solution
requires a 28-pin M40Z300/W and a stand-
alone 128K x8 LPSRAM (SNAPHAT
top to be
ordered separately
■
PMDIP32 is an ECOPACK package
Description
The M48Z512A/Y/V ZEROPOWER
RAM is a
non-volatile, 4,194,304-bit Static RAM organized
as 524,288 words by 8 bits. The devices combine
an internal lithium battery, a CMOS SRAM and a
control circuit in a plastic, 32-pin DIP Module.
For Surface-Mount environments ST provides an
equivalent SMT solution consisting of a 28-pin,
330mil SOIC NVRAM Supervisor (M40Z300/W)
and a 32-pin, (Type II TSOP, 10 x 20mm) 4Mb
LPSRAM. Both 5V and 3V versions are available
(see
Table 2 on page 7
).
The unique design allows the SNAPHAT
battery
package to be mounted on top of the SOIC
package after the completion 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 SNAPHAT housing
is keyed to prevent reverse insertion.
The SNAPHAT battery package is shipped
separately in plastic anti-static tubes or in Tape &
Reel form. The part number is “M4Z32-BR00SH1.
