Product details
Overview
CC1110F32RHHR from Texas Instruments is a low-power sub-1 GHz system-on-chip (SoC) integrating an enhanced 8051 MCU, 32 kB flash, 4 kB RAM, and a CC1101-based RF transceiver operating at 315/433/868/915 MHz ISM bands. It delivers −110 dBm sensitivity at 1.2 kBaud, supports up to 500 kBaud data rate, and achieves 0.3 µA in PM3 sleep mode-ideal for battery-powered wireless sensor nodes and AMR endpoints.
For engineers reviewing the CC1110F32RHHR datasheet, CC1110F32RHHR pinout, CC1110F32RHHR application, or CC1110F32RHHR equivalent, key selection considerations include its QFN-36 package, 21 GPIO capability, integrated AES-128 coprocessor, dual USARTs, and RF performance across 300–928 MHz with programmable output power up to +10 dBm.
Technical Context
The CC1110F32RHHR implements a mixed-signal SoC architecture with separate analog (RF front-end, ADC, crystal oscillators), digital (8051 core, DMA, timers), and mixed-signal (I2S, USB PHY interface) domains. Its radio subsystem uses a fully integrated frequency synthesizer with no external VCO or filter requirements, supporting 2-FSK, GFSK, MSK, ASK, and OOK modulation formats.
Power management includes four distinct operating modes (PM0–PM3), with hardware-controlled transitions between active and ultra-low-power states. The 32.768 kHz crystal oscillator enables precise sleep timer operation, while the high-speed 26 MHz crystal (or 13.5 MHz RC oscillator) serves the CPU and RF sections-mandatory for radio activation.

FAQ
What is the maximum RF output power supported by CC1110F32RHHR?
The CC1110F32RHHR supports programmable RF output power up to +10 dBm across all supported frequency bands (300–348 MHz, 391–464 MHz, and 782–928 MHz). This value is confirmed in the SWRS033H datasheet Section 6.3 and enables flexible range vs. regulatory compliance tuning. The CC1110F32RHHR achieves this using its integrated PA without external matching components beyond the balun.
Does CC1110F32RHHR include a USB interface?
No, CC1110F32RHHR does not include a USB interface. It belongs to the CC1110Fx variant family, which lacks the full-speed USB 2.0 controller found only in CC1111Fx devices. The CC1110F32RHHR provides UART, SPI, I2S, and USB-free GPIO interfaces. If USB connectivity is required, the CC1111F32RHHR is the functionally equivalent USB-enabled counterpart.
What crystal oscillator frequencies are required for CC1110F32RHHR operation?
The CC1110F32RHHR requires a 26 MHz fundamental-mode crystal connected to XOSC_Q1/XOSC_Q2 for full RF and CPU operation. A 32.768 kHz watch crystal may optionally be used for the sleep timer. The high-speed RC oscillator (13.5 MHz) can serve as a backup clock source but cannot drive the RF section-crystal operation is mandatory when the transceiver is active.
How many ADC input channels does CC1110F32RHHR support, and what is the resolution range?
The CC1110F32RHHR supports eight single-ended or differential ADC input channels (P1_0 through P1_7), with configurable resolution from 7 to 12 bits. This is documented in SWRS033H Sections 6.10 and 12.10. The ADC integrates programmable gain and reference selection, enabling direct interfacing with thermistors, current shunts, and other analog sensors without external signal conditioning.
Is CC1110F32RHHR pin-compatible with CC2510F32RHHR?
Yes, CC1110F32RHHR is pin-compatible with CC2510F32RHHR and shares identical QFN-36 packaging, GPIO mapping, and peripheral register layout. As stated in SWRS033H Section 2.1 and the CC2510 datasheet (SWRS052), both devices maintain software compatibility at the HAL and driver layer, enabling drop-in replacement in 2.4 GHz-to-sub-GHz migration paths where RF band change is acceptable.
