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[edit]
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
