Preliminary Data Sheet

BCM43907

WICED™ IEEE 802.11 a/b/g/n SoC with an

Embedded Applications Processor

GENERAL DESCRIPT ION

FEATURES

The Broadcom® Ltd. BCM43907 embedded wireless

system-on-a-chip (SoC) is uniquely suited for

Internet-of-Things applications. It supports all rates

specified in the IEEE 802.11 a/b/g/n

specifications.The device includes an ARM Cortex-

based applications processor, a single stream IEEE

802.11n MAC/baseband/radio, a dual-band 5 GHz

and 2.4 GHz transmit power amplifier (PA), and a

receive low-noise amplifier (LNA). It also supports

optional antenna diversity for improved RF

performance in difficult environments.

The BCM43907 is an optimized SoC targeting

embedded Internet-of-Things applications in the

industrial and medical sensor, home appliance, and

embedded audio markets. Using advanced design

techniques and process technology to reduce active

and idle power, the device is designed for embedded

applications that require minimal power consumption

and a compact size.

The device includes a PMU for simplifying system

power topology and allows for direct operation from a

battery while maximizing battery life.

FEATURES

Application Processor Features

• ARM Cortex-R4 32-bit RISC processor.

• 1 MB of on-chip SRAM for code and data.

• An on-chip cryptography core

• 640 KB of ROM containing WICED SDK

components such as RTOS and TCP/IP stack.

• 17 GPIOs supported.

• Q-SPI serial flash interface to support up to 40

Mbps of peak transfer.

• Support for UART (3), SPI or BSC master (2),

BSC-only (2), and I2S (2) interfaces. (Broadcom

Serial Control (BSC) is an I2C-compatible

interface.)

• Dedicated fractional PLL for audio clock (MCLK)

generation.

• USB 2.0 host and device modes.

• SDIO 3.0 host and device modes.

Key IEEE 801.11x Features

• IEEE 802.11n compliant.

• Single-stream spatial multiplexing up to

150 Mbps.

• Supports 20/40 MHz channels with optional SGI.

• Full IEEE 802.11 a/b/g legacy compatibility with

enhanced performance.

• TX and RX low-density parity check (LDPC)

support for improved range and power efficiency.

• On-chip power and low-noise amplifiers.

• An internal fractional nPLL allows support for a

wide range of reference clock frequencies.

• Integrated ARM Cortex-R4 processor with tightly

coupled memory for complete WLAN subsystem

functionality, minimizing the need to wake up the

applications processor for standard WLAN

functions (to further minimize power consumption

while maintaining the ability to upgrade to future

features in the field).

• Software architecture supported by standard

WICED SDK allows easy migration from existing

discrete MCU designs and to future devices.

• Security support:

– WPA and WPA2 (Personal) support for

powerful encryption and authentication.

– AES and TKIP in hardware for faster data

encryption and IEEE 802.11i compatibility.

– Reference WLAN subsystem provides

Cisco Compatible Extensions (CCX, CCX 2.0,

CCX 3.0, CCX 4.0, and CCX 5.0).

– Wi-Fi Protected Setup and Wi-Fi Easy-Setup

• Worldwide regulatory support: Global products

supported with worldwide design approval.

General Features

• Supports battery voltage range from 3.0V to 4.8V

with an internal switching regulator.

• Programmable dynamic power management.

• 6 Kb OTP memory for storing board parameters.

• 316-bump WLCSP

(4.583 mm × 5.533mm, 0.2mm pitch).
