BCM43907 Preliminary Data Sheet
Standards Compliance
Features
The BCM43907 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.
• Two dedicated BSC¹ interfaces.
• Two SPI master/slave interfaces with operation up to 24 MHz.
Note: Either or both of the SPI interfaces can be used as BSC master interfaces. This is in addition
to the two dedicated BSC interfaces.
• One SPI master interface for serial flash.
• Six dedicated PWM outputs.
• Two I²S interfaces.
• 17 GPIOs.
• IEEE 802.11 a/b/g/n 1×1 2.4 GHz and 5 GHz radio.
• Single- and dual-antenna support.
