MSM1 (Mobile Station Modem 1) was a second generation family of mobile system on chips with CDMA modem capabilities designed by Qualcomm and introduced in 1993. This chip is based on their first generation which was an R&D version only.

Overview

MSM1 was designed as a complete solution for portable or mobile cellular telephones implementing CDMA. The chip is a combined design of what was originally three independent integrated circuits that were fabricated in 1.2 µm. MSM1 supported full-duplex voice and data communication
