Notes: 1. The M48T58 part is offered with the PCDIP28 (i.e. CAPHAT) package only.

2. The SOIC package (SOH28) requires the battery/crystal package (SNAPHAT) which is ordered separately under the part number

"M4T28-BR12SH1" in plastic tube or "M4T28-BR12SH1TR" in Tape & Reel form.

Caution: Do not place the SNAPHAT battery/crystal package "M4T28-BR12SH1" in conductive foam since this will drain the lithium

button-cell battery.

For a list of available options (Speed, Package, etc...) or for further information on any aspect of this device,

please contact the STMicroelectronics Sales Office nearest to you.
