MSM2300 (Mobile Station Modem 2300) was a fourth generation family of 16-bit x86 mobile system on chips with CDMA/FM modem capabilities designed by Qualcomm and introduced in 1997. MSM2300 was backwards compatible with their previous chip and offered additional enhancements such as significant power savings.

Overview

By the fourth generation, Qualcomm MSM2300 have evolved into a fully fledged system on a chip. MSM2300 incorporated a CDMA modem, digital FM processor (DFM), Codebook-Excited Linear Prediction (CELP), and an Intel 80186 processor core. The MSM2300 is pin-compatible with MSM2 as well as almost entirely code-compatible as well making it an ideal drop-in replacement upgrade.

In June 30 1998 Qualcomm introduced the MSM2310, an enhanced derivative of the original MSM2300. The chip was also pin-compatible allowing it to be a drop-in replacement. The new chip added support for Enhanced Variable Rate CODEC (EVRC), the technology that replaced CELP.
