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.
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:
(VPFD = power-fail deselect voltage)
– M48Z512A:
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
■ 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
standalone 128K x8 LPSRAM (SNAPHAT® top to be ordered separately
■ PMDIP32 is an ECOPACK package
