CC2640R2F-Q1 Automotive SimpleLink™ Bluetooth® Smart Wireless MCUs

Texas Instruments' CC2640R2F-Q1 are automotive qualified SimpleLink Bluetooth low energy wireless MCUs

Texas Instruments' SimpleLink Bluetooth low energy CC2640R2F-Q1 device is an AEC-Q100 compliant wireless microcontroller (MCU) targeting Bluetooth 4.2 and Bluetooth 5 low energy automotive applications. These applications include passive entry/passive start (PEPS), remote keyless entry (RKE), car sharing, piloted parking, cable replacement, and smartphone connectivity.

The device is a member of the SimpleLink ultra-low power family of cost-effective, 2.4 GHz RF devices. Very low active RF and MCU current and low-power mode current consumption provide excellent battery lifetime allowing for operation on small coin-cell batteries and a low power-consumption footprint for nodes connected to the car battery. Excellent receiver sensitivity and programmable output power provides industry leading RF performance that is required for the demanding automotive RF environment.

The CC2640R2F-Q1 wireless MCU contains a 32-bit Arm® Cortex®-M3 processor that runs at 48 MHz as the main application processor and includes the Bluetooth 4.2 low energy controller and host libraries embedded in ROM. This architecture improves overall system performance and power consumption and frees up significant amounts of Flash memory for the application.

Additionally, the device is AEC-Q100 qualified at the Grade 2 temperature range (-40°C to +105°C) and is offered in a 7 mm x 7 mm VQFN package with wettable flanks. The wettable flanks help reduce production-line cost and increase the reliability enabled by optical inspection of solder points.

The Bluetooth low energy software stack is available free of charge from Texas Instruments.
