PART NUMBERING

Table 20. Ordering Information Scheme

Note: 1. The 28-pin SOIC package (SOH28) requires the battery/crystal package (SNAPHAT®) which is ordered separately under the part

number “M4TXX-BR12SHX” in plastic tube or “M4TXX-BR12SHXTR” in Tape & Reel form.

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

battery.

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