BCM43903 Preliminary Data Sheet
Standards Compliance
Features
The BCM43903 supports the following features:
• ARM Cortex-R4 clocked at 160 MHz (in 1× mode) or up to 320 MHz (in 2× mode).
• 1 MB of SRAM and 640 KB ROM available for the applications processor.
• One high-speed 4-wire UART interface with operation up to 4 Mbps.
• Two low-speed 2-wire UART interfaces multiplexed on general purpose I/O (GPIO) pins.
• One dedicated BSC1 interface.
Note: Another BSC interface can be defined by reconfiguring GPIOs. See Table 10: “Pin
Multiplexing,” on page 52.
• One SPI master/slave interface with operation up to 24 MHz.
Note: In addition to the dedicated BSC interface, the SPI interface can be used as a BSC master
interface.
Note: Another SPI interface can be defined by reconfiguring GPIOs. See Table 10: “Pin
Multiplexing,” on page 52.
• One SPI master interface for serial flash.
• Six dedicated PWM outputs.
• 17 GPIOs.
• IEEE 802.11 b/g/n 1×1 2.4 GHz radio.
• Single- and dual-antenna support.
