Frequently Asked Questions
What is the CC2540F256RHAT and what protocol does it support?
The CC2540F256RHAT is a Texas Instruments 2.4 GHz System-on-Chip supporting Bluetooth Low Energy (BLE) 4.0 and IEEE 802.15.4. It integrates an 8051 MCU at 32 MHz, 256 KB flash, 8 KB RAM, and a USB 2.0 Full-Speed controller, making it a complete wireless MCU solution in a VQFN-48 package.
What is the operating temperature range of the CC2540F256RHAT?
The CC2540F256RHAT operates over an industrial temperature range of -40 to +85 degrees C, making it suitable for outdoor IoT sensors, industrial automation, and consumer electronics requiring broad environmental tolerance.
What are common applications for the CC2540F256RHAT?
Common applications include USB Bluetooth dongles, wireless HID peripherals (keyboards, mice), fitness trackers, remote controls, smart home sensors, and battery-powered IoT nodes. The integrated USB controller simplifies dongle designs while BLE enables low-power operation.
What package is the CC2540F256RHAT in and how many pins does it have?
The CC2540F256RHAT comes in a VQFN-48 package (48 pins, 7x7 mm body). The RHA suffix in the part number denotes this VQFN package with tape and reel packaging for automated SMT assembly.
What are compatible or alternative parts for the CC2540F256RHAT?
Compatible alternatives include the CC2541F256RHAT (BLE + ANT protocol, same pinout), CC2640R2FRHBT (ARM Cortex-M3, BLE 5.0, pin-compatible upgrade), and the nRF51822-QFAC (Nordic Semiconductor, BLE 4.0, QFN-48). The CC2640R2F is the recommended upgrade path for new designs.
