Description:The M4TXX-BR12SH SNAPHAT top is a detachable lithium power source for ST’s non-volatile TIMEKEEPER surface-mount SOIC (MH) package (28- and 44-pin). The SNAPHAT top contains both the battery and crystal and is designed to be “snapped on” after the SOIC is surface mounted on the PC board. Thus the two piece solution prevents the battery and crystal from being exposed to the high temperatures of the surface mount process. Features 1. Provides battery backup power for serial realtime lock, non-volatile TIMEKEEPER and supervisor devices in the 28- or 44-pin SNAPHAT SOIC package |
