The BCM2140 WCDMA (UMTS) baseband coprocessor enables a modular approach to mobile device design. The BCM2140 efficiently adds 3GPP WCDMA (UMTS) capability to a GSM/GPRS/(EDGE) host baseband processor using Broadcom's flexible standard SRAM memory Interface Figure on page 1 shows the BCM2140 integrated with Broadcom’s BCM2132 GSM/GPRS/EDGE baseband subsystem, which provides a complete multimode WCDMA and EDGE (WEDGE) solution. All WCDMA (UMTS) layer-1 functions are performed by the BCM2140 with layer-2 and higher protocol stack functions for WCDMA (UMTS) executing on the host GSM/GPRS/(EDGE) processor. The enhanced system performance of the BCM2140 relies on a hardware-centric architecture that retains flexibility via on-chip programmability. By Broadcom Corp.
