Package

PC = PCDIP28

MH(2) = SOH28

PM = PMDIP28 (NND)(3)

Temperature Range

1 = 0 to 70°C

6 = –40 to 85°C(4)

Shipping Method

For SOH28:

blank = Tubes (Not for New Design - Use E)

E = ECOPACK Package, Tubes

F = ECOPACK Package, Tape & Reel

TR = Tape & Reel (Not for New Design - Use F)

For PCDIP28:

blank = ECOPACK Package, Tubes

Note: 1. The M48T35 part is offered with the PCDIP28 (e.g., CAPHAT) package only.

2. The SOIC package (SOH28) requires the SNAPHAT® battery package which is ordered separately under the part number “M4TXX-

BR12SH” in plastic tube or “M4TXX-BR12SHTR” in Tape & Reel form (see Table 18.).

3. This package is not to be used for New Design.

4. Available in SOIC package only.

Caution: Do not place the SNAPHAT battery package “M4TXX-BR12SH” in conductive foam as it will drain the lithium button-cell bat-

tery.

For other options, or for more information on any aspect of this device, please contact the ST Sales Office
