Description

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.
