BCM10703UA2KFFB1G

Overview

The BCM10703UA2KFFB1G is a wireless connectivity solution from Broadcom Limited, integrating a Bluetooth Low Energy (BLE) radio with an ARM Cortex-M3 microcontroller. It operates in the 2.4 GHz ISM band and supports BLE protocol standards. The device utilizes an FCBGA-49 package for surface mount installation. Key electrical parameters include a supply voltage range of 1.2 V to 3.3 V and an operating temperature range typically spanning -40°C to +85°C. It features integrated program memory and data RAM suitable for embedded applications requiring low power consumption and compact form factors.

Feature Summary

Integrates a Bluetooth Low Energy transceiver with an ARM Cortex-M3 processor core
Supports IEEE 802.15.4 and Bluetooth Smart protocols for wireless communication
Designed for low-power operation in portable and battery-driven devices

Applications

Wearable electronics and health monitoring devices
Smart home sensors and actuators
Asset tracking tags and beacons

Procurement Notes

Verify the specific suffix '1G' against official Broadcom documentation to confirm pinout, tape-and-reel specifications, and RoHS compliance status. Ensure compatibility with the intended PCB footprint and reflow profile requirements before procurement.

Selection Notes

Select this component when a combined MCU and BLE radio is required to reduce board space and bill of materials count. Consider the available GPIO count and memory size relative to application firmware complexity. Verify that the FCBGA-49 package is supported by the manufacturing assembly capabilities.

Part Context

This part belongs to the Broadcom BCM2070x series of single-chip Bluetooth solutions. These components are designed to replace discrete Bluetooth modules by combining RF and baseband processing with general-purpose computing resources on a single die.

Replacement Considerations

Check for direct pin-to-pin replacements within the BCM2070x family, such as the BCM20703 or BCM20706 variants, ensuring software compatibility and feature parity. Confirm availability of updated engineering samples if transitioning from older revisions.
