M4Z28-BR00SH Datasheet PDF - ST Microelectronics

●Description

●The M4Zxx-BR00SH SNAPHAT® top is a detachable lithium power source for ST’s non volatile 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.
