Product details
Overview
CC430F5137IRGZ from Texas Instruments is an ultra-low-power System-on-Chip (SoC) microcontroller integrating a sub-1 GHz RF transceiver core (CC1101), 16-bit MSP430 CPUXV2, 32 KB flash, 4 KB RAM, 12-bit ADC with six external inputs plus internal temperature/battery sensors, and dual USCI modules supporting UART/I²C/SPI. It operates from 1.8 V to 3.6 V and targets battery-powered wireless sensor nodes.
For engineers reviewing the CC430F5137IRGZ datasheet, CC430F5137IRGZ pinout, CC430F5137IRGZ application, or CC430F5137IRGZ equivalent, key selection considerations include its 48-pin VQFN package, integrated RF transceiver with programmable data rates up to 500 kBaud, −117 dBm sensitivity at 0.6 kBaud, AES-128 security coprocessor, and support for EN 300 220 and FCC Part 15 compliance.
Technical Context
The CC430F5137IRGZ implements a tightly coupled SoC architecture where the MSP430 CPUXV2 core interfaces directly with the CC1101-derived RF subsystem via dedicated packet-handling logic and shared memory-mapped registers. Its unified clock system uses an FLL with multiple crystal and internal sources-including separate 32 kHz RTC and 26 MHz RF oscillator domains-to enable independent low-power operation of MCU and radio blocks.
It supports five low-power modes (LPM0–LPM4) with wake-up from standby in under 6 µs, and integrates hardware accelerators including a 32-bit multiplier, 3-channel DMA, and CRC16 engine. The RF front end features differential RF_P/RF_N I/O, programmable output power up to +12 dBm, digital RSSI, carrier sense, and automatic clear channel assessment (CCA) for listen-before-talk protocols.
