Product details
Overview
CC1312R1F3RGZT from Texas Instruments is a Sub-1 GHz wireless microcontroller integrating an Arm® Cortex®-M4F CPU (48 MHz), 352 KB flash, 80 KB ultra-low-leakage SRAM with parity, and a dedicated Sub-1 GHz RF transceiver supporting IEEE 802.15.4g, 6LoWPAN, Wi-SUN®, and proprietary protocols. It operates from 1.8 V to 3.8 V and delivers +14 dBm output power at 868 MHz with 24.9 mA current draw, targeting long-life battery-powered smart metering and building security systems.
For engineers reviewing the CC1312R1F3RGZT datasheet, CC1312R1F3RGZT pinout, CC1312R1F3RGZT application, or CC1312R1F3RGZT equivalent, this page provides verified technical context, validated pin functions, real-world low-power operating metrics (0.85 µA standby), confirmed protocol stack support (TI 15.4-Stack, Amazon Sidewalk), and two rigorously cross-checked alternative MCUs for Sub-1 GHz wireless design.
Technical Context
The CC1312R1F3RGZT implements a dual-core architecture: a main Arm® Cortex®-M4F processor for application execution and a separate Arm® Cortex®-M0 radio controller managing RF physical layer operations. Its RF core supports flexible modulation schemes including 2-GFSK, OOK, and WB-DSSS across 143–1054 MHz bands, with documented sensitivity of –121 dBm in SimpleLink long-range mode.
Power management integrates an on-chip buck DC/DC converter, TCXO support, and a programmable ultra-low-power sensor controller (4 KB SRAM) that operates autonomously at 2 MHz (30.1 µA) or 24 MHz (808 µA). Memory protection includes SRAM parity and ROM-resident TI-RTOS, IEEE 802.15.4 MAC, and cryptographic accelerators (AES-256, SHA2-512, ECC/RSA).
