1. The M48T35 part is offered only in the PCDIP28 (i.e. CAPHAT™) package.
2. The M48T35Y is available only in the SOH28 (i.e. SNAPHAT SOIC) package.
3. The SOIC package (SOH28) requires the SNAPHAT
4. Temperature grade 6 (–40 to +85 °C) devices are not for new design. Contact ST sales office
Do not place the SNAPHAT battery package “M4TXX-BR12SH” in conductive foam as it will
drain the lithium button-cell battery.
For other options, or for more information on any aspect of this device, please contact the
