TI CC2745R10 Automotive Grade BLE 6.0 Module with Channel Sounding
In the wave of automotive intelligence, applications such as digital keys, passive entry, battery management systems (BMS), and in-vehicle diagnostics demand wireless connectivity with high reliability, Độ trễ thấp, precise positioning, and ultra-low power consumption. Ordinary consumer-grade Bluetooth modules can no longer meet the stringent requirements of automotive-grade scenarios.
Feasycom introduces the FSC-BT2004TV automotive grade BLE module, based on the TI CC2745R10-Q1 chipset. It supports the Bluetooth 6.0 core specification and integrates Channel Sounding technology, delivering both precision ranging and secure connectivity for digital car keys, PEPS, BMS, và hơn thế nữa.
Automotive-Grade Certification
The core chipset of FSC-BT2004TV is T CC2745R10, which is AEC-0100 Grade 2 qualified, and the module is designed to meet automotive-grade standards.
- Wide temperature range: -40oC đến +85oC
- High ESD protection: HBM ±2000V (except ANT pin), ANT pin ±1000V
- Ultra-low standby current: ≤3μA (standby), ≤160nA (Deep sleep) – ideal for coin-cell powered car keys
For Tier 1 suppliers and OEMs, choosing an automotive-grade module reduces project risk and shortens DV/PV validation cycles.
Bluetooth 6.0
The breakthrough of Bluetooth 6.0 is Channel Sounding, a high-precision distance measurement technology based on phase-based ranging. FSC-BT2004TV natively supports this feature, bringing two key benefits:
Centimeter-level positioning accuracy: Unlike traditional RSSI ranging, Channel Sounding is more resilient to multipath interference, achieving sub-meter distance estimation. This enables the core experience of digital keys: “unlock as you approach, lock as you leave”.
Relay attack protection: The encrypted round-trip ranging protocol effectively defends against man-in-the-middle attacks such as signal amplifiers, meeting CCC security requirements.
Balancing Low Power and High Performance
FSC-BT2004TV strikes an ideal balance between power consumption and processing capability:
| Parameter | Typical Value |
| Core | Arm Cortex-M33, 96MHz |
| RX current | ≤6.1mA |
| TX current @0dBm | ≤7.7mA |
| TX current @10dBm | ≤24.5mA |
| Active mode (MCU@96MHz) | 6.8MA |
| Deep sleep | ≤160nA |
Rich Interfaces for Flexible Integration
The module comes in a 13mm × 26.9mm stamp-hole package, providing up to 23 GPIOs and:
- Uart (default 115200bps, up to 921600bps)
- I2c (up to 400kHz)
- SSI/SPI (master/slave, up to 4MHz)
- CAN-FD controller (ISO16845-1:2016 certified)
- 8-channel capacitive touch sensor
- Cảm biến nhiệt độ tích hợp
Whether used as a standalone Bluetooth MCU or as a co-processor in an automotive system, it offers flexible adaptation.
- Key Application Scenarios
| Domain | Specific Applications |
| Automotive Digital Key | Phone-as-a-Key (PaaK), PEPS, RKE, car-sharing authorization |
| In-vehicle Diagnostics & Configuration | OBD Bluetooth adapters, aftermarket diagnostic tools |
| Smart Cockpit Peripherals | Bluetooth game controllers, rear-seat entertainment headphones, in-car beacons |
| IoT công nghiệp | Asset tracking, AGV dispatching, automotive-grade sensor nodes |
