MSM2 (Mobile Station Modem 2) was a third generation family of 16-bit x86 mobile system on chips with CDMA modem capabilities designed by Qualcomm and introduced in 1995.

Overview

The MSM2 is a dual-mode (CDMA/AMPS) and digital processor system on chip. The chip incorporated a CDMA processor, a digital FM processor (DFM), Qualcomm's codebook-excited linear prediction (CELP), and an Intel 80186 processor core. The MSM2 works tightly with a number of support chips that provide facilities for handling everything from FM to audio.
