blank = ECOPACK® package, tubes

Caution:

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® battery package which is ordered

separately under the part number “M4TXX-BR12SH” (see Table 17 on page 25).

4. Temperature grade 6 (–40 to +85 °C) devices are not for new design. Contact ST sales office

for availability.

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

ST sales office nearest you.
