The CC1110F32RHHR is a microcontroller and radio frequency (RF) system-on-chip (SoC) designed and manufactured by Texas Instruments. This SoC operates in the sub-1GHz frequency band and integrates the TI MSP430 MCU core with 16kB of flash memory, for an ultra-low power, low cost solution. It has an Enhanced ShockBurst low power RF protocol, on-chip transmit/receive packet handling, and an integrated RX/TX data FIFO, making it ideal for battery powered applications such as sensors, smart grids, wearables, and other wireless applications with a limited physical size. The CC1110F32RHHR includes an 8051 compatible MCU core with 16-bit, 20-bit, or 23-bit instruction encoding, and it supports up to 32 general-purpose I/O pins for digital and analog interface extension. The integrated RF transceiver supports very low data rate communication, with 6 dBm output power, 15.5 dBm sensitivity for 1 Mbps mode, and 19.5 dBm sensitivity for 250 Kbps mode. The CC1110F32RHHR is supplied in plastic LQFP-32 package.
