Small Form Factor Bluetooth Low Energy (BLE) Reference Design

TIDA-00358

Design files

Overview

This design showcases the CC254x family of Bluetooth® low energy (BLE) wireless microcontrollers (MCUs) + a meandered F antenna in a compact form factor that can be soldered to an existing PCB. This reference design provides access to all I/Os of the BLE wireless MCU allowing the evaluation of BLE connectivity in existing systems. This design is compatible with Texas Instrumentss royalty-free BLE stack that include example applications for faster evaluation.

Features
  • Automotive-qualified CC2541-Q1 available (Note: There is a slight pinout change from CC2541)
  • Provides reference design for Bluetooth Low Energy (BLE) antenna design- leveraging low cost trace antenna
  • Antenna performance provided in the test data
  • 22 Pin Functions are available
  • 2 SPI ports/ UART ports
  • I2C port
  • 2 GPIO ports with 20mA drive capability
  • 21 multiplex GPIOs
  • 8 ADC channels
  • 32 KHz-based sleep timer
  • BLE firmware and iOS app software is free of charge when used with TI radios or similar to help customers get to market faster
