4 Mbit (512 Kbit x 8) ZEROPOWER® SRAM
Features
â–  Integrated, ultra low power SRAM, power-fail
control circuit, and battery
â–  Conventional SRAM operation; unlimited
WRITE cycles
â–  10 years of data retention in the absence of
power
â–  Automatic power-fail chip deselect and WRITE
protection
â–  Two WRITE Protect voltages:
(VPFD = power-fail deselect voltage)

VCC = 4.75 to 5.5V, 4.5V ≤ VPFD ≤ 4.75V
– M48Z512AY:
VCC = 4.5 to 5.5V, 4.2V ≤ VPFD ≤ 4.5V
– M48Z512AV:
VCC = 3.0 to 3.6V, 2.8V ≤ VPFD ≤ 3.0V
â–  Battery internally isolated until power is applied
â–  Pin and function compatible with JEDEC
standard 512K x 8 SRAMs
â–  SOIC package provides direct connection for a
SNAPHAT top which contains the battery
â–  SNAPHAT housing (battery) is replaceable
â–  Equivalent Surface-Mount (SMT) solution
requires a 28-pin M40Z300/W and a stand-
alone 128K x8 LPSRAM (SNAPHAT® top to be
ordered separately
â–  PMDIP32 is an ECOPACK package

PMDIP32 (PM)
Module
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.
