802.11a/b/g Transceiver for SDIO and PCI Express®

The BCM4312 provides one-chip IEEE 802.11a/b/g MAC, baseband, and direct conversion dual-band radio functions for wireless LAN connectivity supporting data rates from 1 Mbps to 54 Mbps in the 2.4-GHz or 5-GHz bands.

Broadcom's revolutionary one-chip architecture implemented in a bulk CMOS process greatly reduces the external components typically required for IEEE 802.11a/b/g implementations, resulting in significant cost, power, and footprint savings. The extreme integration of the BCM4312 enables low rest-of-BOM (RBOM), singled-sided, two-layer PCB-based designs.
