The M4Z28-BR00SH1 is a part of M4Z28 series Battery Backed SRAM.It has an operating temperature ranging from -40 °C to +85 °C and it comes in SOIC Packaging.

The M4Zxx-BR00SH SNAPHAT® top is a detachable lithium power source for ST’s nonvolatile ZEROPOWER® surface-mount SOIC (MH) package (28-pin).

The SNAPHAT top contains a lithium battery and is designed to be "snapped on" after the SOIC is surface mounted on the PC board. The two-piece solution prevents the battery from being exposed to the high temperatures of the surface mount process.

Features:

• Provides battery backup power for non-volatile ZEROPOWER® and supervisor devices in the 28-pin SNAPHAT® SOIC package
• Removable battery avoids heat associated with surface-mount process
• Snaps directly onto surface-mounted SNAPHAT® SOIC
• Choice of battery capacities
• M4Z28-BR00SH = 48 mAh
• Keyed insertion to insure proper assembly
• Removable for replacement and proper disposal
• Pb-free package
• Available in tubes or tape & reel
