Texas Instruments CC430F6147IRGCT

Overview

CC430F6147IRGCT from Texas Instruments is a true ultra-low-power system-on-chip (SoC) integrating an MSP430 16-bit RISC microcontroller core, a CC1101-based sub-1 GHz RF transceiver, 32 KB flash, 4 KB RAM, 10-bit ADC with 8 external inputs, hardware AES-128 encryption, and integrated LCD driver supporting up to 96 segments - designed for battery-powered wireless sensor nodes in smart metering and industrial telemetry.

For engineers reviewing the CC430F6147IRGCT datasheet, CC430F6147IRGCT pinout, CC430F6147IRGCT application, or CC430F6147IRGCT equivalent, key selection criteria include its LPM4.5 shutdown current (0.3 µA), RF sensitivity (–117 dBm at 0.6 kBaud, 315 MHz), integrated RTC with calendar mode, 44 GPIOs, and VQFN-64 package compatibility with space-constrained wireless endpoint designs.

Technical Context

The CC430F6147IRGCT implements a tightly coupled SoC architecture where the MSP430 CPUXV2 core directly controls the CC1101-derived RF subsystem via dedicated memory-mapped registers and DMA channels. Its unified clock system uses an FLL with internal REFO and external XT1/XT2 oscillators to synchronize MCU timing, RF synthesizer operation, and ADC sampling without external clock sources.

RF packet handling is offloaded by on-chip hardware: sync word detection, address filtering, CRC generation/verification, automatic clear channel assessment (CCA), and digital RSSI output are all executed autonomously - reducing CPU wake-ups and enabling sub-µA average system current in listen-before-talk sensor networks.

FAQ

What is the maximum RF output power supported by the CC430F6147IRGCT?

The CC430F6147IRGCT supports programmable RF output power up to +12 dBm across all supported frequency bands (300–348 MHz, 389–464 MHz, 779–928 MHz). This is achieved using the integrated CC1101-derived RF core with optimized PATABLE settings - enabling reliable communication in dense urban or shielded indoor environments without external power amplifiers. The CC430F6147IRGCT maintains this output level while drawing typical TX current of 27.5 mA at 915 MHz.

Does the CC430F6147IRGCT support hardware AES encryption?

Yes, the CC430F6147IRGCT includes a dedicated 128-bit AES security coprocessor that performs encryption and decryption operations independently of the CPU. This allows secure firmware updates and payload encryption for protocols like Wireless M-Bus EN 13757‑4:2005 without consuming CPU cycles or increasing active power - a key differentiator of the CC430F6147IRGCT in regulated utility applications.

How many analog inputs does the 10-bit ADC in the CC430F6147IRGCT support?

The CC430F6147IRGCT features a 10-bit ADC with eight external analog input channels plus internal temperature and battery voltage sensors. This configuration enables direct connection of multiple external sensors (e.g., thermistors, pressure transducers) without external multiplexers - a capability confirmed in the device comparison table and functional block diagram for the CC430F614x series. The CC430F6147IRGCT ADC also includes sample-and-hold and autoscan features for efficient multi-channel acquisition.

What package type and dimensions does the CC430F6147IRGCT use?

The CC430F6147IRGCT is packaged in a 64-pin VQFN (RGC) with body dimensions of 9 mm × 9 mm and an exposed thermal pad. This package is explicitly listed in the Device Information table of the SLAS555B datasheet and matches the pin diagram in Figure 4-1. The RGC variant supports 44 GPIOs and integrates the full feature set of the CC430F614x family, distinguishing it from the smaller 48-pin RGZ package used by CC430F514x devices.

Can the CC430F6147IRGCT operate from a single 2-cell alkaline battery?

Yes, the CC430F6147IRGCT operates across a wide supply range of 1.8 V to 3.6 V - fully covering the discharge curve of two AA or AAA alkaline batteries (nominal 3.0 V, down to ~2.0 V under load). Its ultra-low-power modes - including 0.3 µA in LPM4.5 shutdown and 1.0 µA in RTC-only LPM3.5 - ensure multi-year operation on primary cells without voltage regulation losses, a core design objective validated in TI's application notes for smart metering endpoints using the CC430F6147IRGCT.
