Texas Instruments CC2510F32RHHR

Overview

CC2510F32RHHR from Texas Instruments is a low-power 2.4 GHz system-on-chip (SoC) integrating an enhanced 8051 MCU, 32 kB flash, 4 kB RAM, and a CC2500-based RF transceiver. It operates in the 2400–2483.5 MHz ISM band with −103 dBm sensitivity at 2.4 kBaud, 17.1 mA RX current, and supports wireless keyboard/mouse and low-power telemetry applications.

For engineers reviewing the CC2510F32RHHR datasheet, CC2510F32RHHR pinout, CC2510F32RHHR application, or CC2510F32RHHR equivalent, this page delivers verified technical context, package mapping, real-world use cases, and validated alternative options for embedded 2.4 GHz wireless designs requiring compact size, ultra-low power (0.3 µA in PM3), and integrated MCU+RF functionality.

Technical Context

The CC2510F32RHHR implements a fully integrated 2.4 GHz transceiver derived from the CC2500 core, supporting 2-FSK, GFSK, and MSK modulation with programmable data rates up to 500 kBaud and output power up to +1 dBm. Its RF section includes digital RSSI/LQI, automatic CRC handling, and hardware-accelerated packet parsing.

It pairs the RF subsystem with an optimized 8051 MCU running at up to 26 MHz, backed by 32 kB flash and 4 kB SRAM, DMA controller, two USARTs, 7–12-bit ADC (8-channel), 128-bit AES coprocessor, and 21 GPIO pins - all operating from a 2.0–3.6 V supply with four configurable power modes including 0.3 µA PM3.

FAQ

What is the maximum data rate supported by CC2510F32RHHR?

The CC2510F32RHHR supports programmable data rates up to 500 kBaud using 2-FSK, GFSK, or MSK modulation schemes. At 2.4 kBaud, it achieves −103 dBm receiver sensitivity; at higher rates like 500 kBaud, sensitivity decreases but remains suitable for short-range, high-throughput applications such as wireless audio streaming or firmware updates. The CC2510F32RHHR does not support Bluetooth or IEEE 802.15.4 MAC layer features - its data rate flexibility is intended for custom protocol implementation.

Does CC2510F32RHHR include a USB controller?

No, CC2510F32RHHR does not include a USB controller. That feature is exclusive to the CC2511Fx variant (e.g., CC2511F32RHHR). The CC2510F32RHHR provides two USARTs supporting UART and SPI modes, I2S for audio, and a 7–12-bit ADC - but no USB PHY or endpoint FIFO. Engineers requiring USB connectivity must select the CC2511Fx family or add an external USB-UART bridge when using CC2510F32RHHR.

What crystal oscillator frequency is required for RF operation in CC2510F32RHHR?

The CC2510F32RHHR requires a 24–27 MHz fundamental-mode crystal connected to XOSC1/XOSC2 pins for RF operation. A 26 MHz crystal is commonly used and specified in TI reference designs. The high-speed crystal oscillator must be active during radio transmit/receive - the internal RC oscillator cannot meet RF phase-noise or stability requirements. The optional 32.768 kHz crystal supports low-power sleep timer operation but plays no role in RF functionality.

How many GPIO pins does CC2510F32RHHR provide, and are they 5V-tolerant?

The CC2510F32RHHR provides 21 configurable GPIO pins across Ports 0–2. These pins operate at the core supply voltage (2.0–3.6 V) and are **not 5V-tolerant** - applying voltages above VDD + 0.3 V risks permanent damage per Absolute Maximum Ratings (Table 2). External level-shifting is required for interfacing with 5V peripherals. All GPIOs support interrupt-on-change and can be configured as inputs with weak pull-ups or outputs with slew-rate control.

Is CC2510F32RHHR RoHS compliant and what is its package type?

Yes, CC2510F32RHHR is RoHS compliant and classified as a "green package" - containing no antimony or bromine. It uses a 36-pin QFN (Quad Flat No-lead) package measuring 6 mm × 6 mm with 0.5 mm pin pitch and an exposed thermal pad. This compact footprint supports high-density PCB layouts in space-constrained applications such as wireless mice and remote controls. The RHHR suffix explicitly denotes this QFN-36 package variant.
