TI公司的CC2640R2F是SimpleLink™ Bluetooth®蓝牙低功耗无线MCU,包括32位ARM®Cortex®-M3核,主处理器运行在48MHz,具有丰富的外设备特性包括独特的超低功耗传感器控制器,主要用在家庭和建筑物自动化,工业领域如物流和生产自动化,健康和医疗,销售,运动和健身以及HID.本文介绍了CC2640R2F主要特性,框图,差分和单端应用电路,以及参考设计TIDA-01624主要特性,框图和主要指标,电路图,材料清单和PCB设计图.

The CC2640R2F device is a wireless microcontroller (MCU) targeting Bluetooth® 4.2 and Bluetooth 5 lowenergyapplications.

The device is a member of the SimpleLink™ ultra-low power CC26xx family of cost-effective, 2.4-GHz RFdevices. Very low active RF and MCU current and low-power mode current consumption provide excellentbattery lifetime and allow for operation on small coin cell batteries and in energy-harvesting applications.

The SimpleLink Bluetooth low energy CC2640R2F device contains a 32-bit ARM® Cortex®-M3 core thatruns at 48 MHz as the main processor and a rich peripheral feature set that includes a unique ultra-lowpower sensor controller. This sensor controller is ideal for interfacing external sensors and for collectinganalog and digital data autonomously while the rest of the system is in sleep mode. Thus, the CC2640R2Fdevice is great for a wide range of applications where long battery lifetime, small form factor, and ease ofuse is important.

The power and clock management and radio systems of the CC2640R2F wireless MCU require specificconfiguration and handling by software to operate correctly, which has been implemented in the TI-RTOS.

TI recommends using this software framework for all application development on the device. The completeTI-RTOS and device drivers are offered in source code free of charge from

Bluetooth low energy controller and host libraries are embedded in ROM and run partly on an ARM®Cortex®-M0 processor. This architecture improves overall system performance and power consumptionand frees up significant amounts of flash memory for the application.

This reference design demonstrates highly-accuratesensing of skin temperature using the TMP117 highprecisiondigital temperature sensor with theCC2640R2F wireless MCU. This users guide providesdesign guidance for skin temperature measurement inmedical and wearable applications along with anevaluation software and smart device application.

With the need to integrate sensors into newer wireless and cloud applications, the Bluetooth-enabled,high-accuracy skin temperature measurement flex patch provides a wireless solution for receiving highaccuracy skin temperature measurements on a Bluetooth-capable device, such as a smartphone or tablet.Through direct contact with the skin,the TMP117 high-accuracy, low-power, digital temperature sensorcan send 16-bit digital output data through the I²C to a CC2640R2F SimpleLink™ Bluetooth low energy (BLE) wireless microcontroller (MCU). After collecting this data, the CC2640R2F can use Bluetoothprotocol to transmit the data to a Bluetooth-connected device.

The patch operates on a 3-V, flexible thin-film battery, which is made possible due to the very low powerconsumption of the design components. For testing and demonstration purposes, the designer can usethe large contact pads of the device to receive external power from other sources when a battery is notconnected.

There are two primary modes of operation for the patch: active and inactive mode. When the patch isinactive, the CC2640R2F enters a complete shutdown state and the TMP117 is powered down. Thismode allows a 3-year shelf life for the patch without a significant depletion of stored energy in the battery.

When the designer presses the wake-up switch, the flex patch enters active mode and the TMP117begins reading and auto-advertising temperature data the CC2640R2F BLE device can receive.

When the designer uses the software as designed, the only way to return the patch from active modeback to inactive mode is to remove and reapply the device power. In healthcare applications, reuse orextended use of monitoring patches may pose risks to patient health due to hygiene concerns. Thesoftware for this patch was created with the intent to make the design disposable so that each patch canonly be used once. An alternative for temperature-monitoring systems is to use a removable covering thatcan be disposed of after use. This is common in designs of probe-type thermometers for oral temperaturemeasurements. If this method is used, the system and these covers must be characterized as the finaldesign. For probes, the designer can modify the software to move between active and inactive mode, butan MCU must be in the probe to use Bluetooth communication protocol under this modification.
