BCM5356x Family

802.11b/g and Single-Stream 802.11n 2.4-GHz Router

The BCM5356 processor is Broadcom's lowest cost and most integrated entry level router. It incorporates IEEE 802.11b/g and single-stream IEEE 802.11n MAC and baseband and a 2.4GHz radio transceiver to achieve data rates of up to 150 Mbps. Also on chip is a powerful 333-MHz MIPS 74K CPU core with 32-KB instruction cache and a 32K data cache and an optimized memory subsystem architecture that delivers system performance of over 100Mbps TCP throughput.

In addition, the BCM5356 integrates a highly reliable 2.4 GHz power amplifier that delivers the equivalent performance as external power amplifiers. The BCM5356 includes a variety of components on chip, thereby reducing the Bill of Materials (BOM), and enabling smaller form factor and lower cost PCB solutions. The BCM5356 is implemented in 65nm CMOS technology that enables lower overall power consumption compared to previous generations. Further, it implements a Green Wi-Fi mode that dynamically switches off components of the chip thereby reducing active power consumption.

This solution comes with two options which include:

BCM5356: Single-chip 2.4G single stream IEEE 802.11n retail router

BCM5356U: Single-chip 2.4G single stream IEEE 802.11n retail router with USB support
