M4Z28-BR00SH M4Z32-BR00SH ZEROPOWER SNAPHAT battery Datasheet - production data Description The M4Zxx-BR00SH SNAPHAT top is a detachable lithium power source for STs non- volatile ZEROPOWER surface-mount SOIC 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 SNAPHAT battery process. Features Provides battery backup power for non-volatile ZEROPOWER SRAM 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 M4Z32-BR00SH = 120 mAh Keyed insertion to insure proper assembly Removable for replacement and proper disposal Pb-free package Available in ECOPACK packages, tubes February 2014 DocID013124 Rev 4 1/16 This is information on a product in full production. www.st.comContents M4Z28-BR00SH, M4Z32-BR00SH Contents 1 Device overview 5 2 Mechanical information 6 2.1 Battery characteristics 7 2.2 UL recognition 7 2.3 Battery life . 7 2.4 General notes . 7 3 Maximum ratings 9 4 DC and AC parameters 10 5 Package mechanical data 11 6 Part numbering 13 7 Environmental information . 14 8 Revision history . 15 2/16 DocID013124 Rev 4
