Example:

M48T

–100

Device type

M48T

Supply voltage and write protect voltage

08(1) = VCC = 4.75 to 5.5 V; VPFD = 4.5 to 4.75 V

The M48T08/18 part is offered with the PCDIP28 (e.g., CAPHAT™) package only.

18/08Y = VCC = 4.5 to 5.5 V; VPFD = 4.2 to 4.5 V

Speed

–100 = 100 ns

–150 = 150 ns

–10 = 100 ns (M48T08Y)

Package

PC(1) = PCDIP28

MH(2) = SOH28

The SOIC package (SOH28) requires the SNAPHAT® battery/crystal package which is ordered separately

under the part number “M4TXX-BR12SH” in plastic tube or “M4TXX-BR12SHTR” in tape & reel form (see

Table 17). The M48T08Y part is offered in the SOH28 (SNAPHAT) package only.

Temperature range

1 = 0 to 70 °C
