TI CC2745R10 0

 

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, нізкая затрымка, 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, і многае іншае.

 

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: -40℃ да +85 ℃
  • 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, 96МГц
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:

  • Уарт (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
  • Убудаваны датчык тэмпературы
