MSM3000 (Mobile Station Modem 3000) was a fifth generation family of 32-bit ARM mobile system on chips with IS-95 (cdmaOne) capabilities designed by Qualcomm and introduced in 1998. This chip marked a significant departure from all their previous generation of chips by switching to an ARM-based (ARM7TDMI) core. Previously Qualcomm was using an embedded 80186 by Intel. This family was developer in parallel to the MSM5000 family which was based on the CDMA2000 standard.
Overview
In mid-1998 Qualcomm announced that they've acquired a license for ARM7TDMI. The switch upgraded their SoC from a 16-bit (which was previous based on Intel's 80186) to a 32-bit ARM (implementing the ARMv4 instruction set). The switch had big impact on the chip - die size was decreased, power consumption was significantly reduced, and performance was increased. MSM3000 offered data rates of up to 86 Kibit/s
