Product details
Overview
CC1352R1F3RGZT from Texas Instruments is a multiprotocol wireless microcontroller integrating Arm® Cortex®-M4F CPU (48 MHz), 352KB flash, 80KB SRAM with parity, dual-band Sub-1 GHz and 2.4 GHz RF transceiver, and autonomous ultra-low-power sensor controller. It supports Bluetooth 5.2 LE, Zigbee®, Thread, IEEE 802.15.4, and proprietary protocols for battery-powered building security and smart metering systems.
For engineers reviewing the CC1352R1F3RGZT datasheet, CC1352R1F3RGZT pinout, CC1352R1F3RGZT application, or CC1352R1F3RGZT equivalent, this page delivers verified technical context, validated pin functions, real-world power mode data, protocol stack compatibility, and direct alternative comparisons - all grounded in TI's official SWRS196I documentation and RGZ package specifications.
Technical Context
The CC1352R1F3RGZT integrates two independent processors: a 48-MHz Arm Cortex-M4F main CPU for application execution and protocol stacks, and a dedicated Arm Cortex-M0 RF core handling radio timing, modulation, and PHY layer operations. Its dual-band RF architecture supports concurrent Sub-1 GHz (143–1054 MHz) and 2.4 GHz operation with separate differential RF ports (RF_P_SUB_1GHZ/RF_N_SUB_1GHZ and RF_P_2_4GHZ/RF_N_2_4GHZ).
It features an autonomous ultra-low-power sensor controller with 4KB SRAM, capable of ADC sampling at 1 Hz with only 1 µA system current, operating independently of the main CPU. Power management includes integrated buck DC/DC converter, programmable brown-out detection, and multiple retention modes - including 0.85 µA standby with RTC and full 80KB RAM retention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar multiprotocol wireless MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CC2652R1F3RGZT | 2.4 GHz only (no Sub-1 GHz RF); identical M4F core, memory, and peripherals. | Limited to BLE/Zigbee/Thread in 2.4 GHz band; cannot support regional Sub-1 GHz deployments (EU 868 MHz, US 915 MHz). | Select when global Sub-1 GHz compliance is unnecessary and board space allows simplified RF front-end. |
| CC1352P1F3RGZT | Includes +20 dBm high-power amplifier; higher TX current (38 mA @ +20 dBm); same dual-band RF architecture. | Suitable for ultra-long-range (>5 km) point-to-multipoint networks where link budget exceeds CC1352R1F3RGZT's +14 dBm capability. | Choose when extended range justifies higher power consumption and added RF filtering complexity. |
Compared with CC1352R1F3RGZT, CC2652R1F3RGZT sacrifices Sub-1 GHz flexibility for lower cost and simpler layout, while CC1352P1F3RGZT trades battery life for raw RF range - making CC1352R1F3RGZT the optimal balance for globally deployable, battery-operated dual-band edge nodes.

FAQ
What wireless protocols does the CC1352R1F3RGZT natively support without external software?
The CC1352R1F3RGZT includes Bluetooth 5.2 Low Energy, IEEE 802.15.4 MAC, and protocol stacks for Thread and Zigbee preloaded in its 256KB ROM. These are fully functional out-of-box with TI's SimpleLink SDK. Additional protocols like Wi-SUN, MIOTY, and Amazon Sidewalk are supported via downloadable software libraries - no external MCU or co-processor required. The CC1352R1F3RGZT's ROM-resident stacks reduce flash usage and accelerate time-to-market.
Does the CC1352R1F3RGZT support concurrent Sub-1 GHz and 2.4 GHz radio operation?
Yes, the CC1352R1F3RGZT supports true concurrent dual-band operation using its Dynamic Multiprotocol Manager (DMM) driver. It can run Bluetooth 5.2 on 2.4 GHz while simultaneously transmitting on Sub-1 GHz using TI 15.4-Stack - enabled by physically separate RF paths (RF_P_SUB_1GHZ/RF_N_SUB_1GHZ and RF_P_2_4GHZ/RF_N_2_4GHZ) and independent RF core scheduling. This eliminates time-slicing latency and enables seamless gateway bridging.
What is the minimum supply voltage for full functionality of the CC1352R1F3RGZT?
The CC1352R1F3RGZT operates across 1.8 V to 3.8 V, but full RF performance (including +14 dBm Sub-1 GHz output) requires ≥2.1 V when using boost mode (VDDR = 1.95 V). At 1.8 V, the device remains functional in active and standby modes, but maximum transmit power is limited to +10 dBm in Sub-1 GHz and +3 dBm in 2.4 GHz. The brown-out detector triggers at 1.70 V (initial boot) and 1.77 V (normal operation), ensuring safe reset before logic corruption.
How does the sensor controller in the CC1352R1F3RGZT reduce system power consumption?
The CC1352R1F3RGZT's autonomous sensor controller executes low-power sensing tasks (e.g., 1-Hz ADC sampling) at 2 MHz while the main M4F CPU remains in deep sleep, drawing only 30.1 µA. It uses dedicated 4KB SRAM and programmable instruction set to process sensor data without waking the CPU - reducing average system current by up to 90% compared to polling-based architectures. This directly enables >10-year battery life in CR2032-powered endpoints.
Is the CC1352R1F3RGZT qualified for industrial temperature operation?
Yes, the CC1352R1F3RGZT is specified for –40°C to +105°C junction temperature and maintains 0.85 µA standby current with full RAM retention even at 85°C ambient. Its 80KB SRAM includes parity protection to prevent soft errors from radiation-induced bit flips - achieving <1 FIT failure-in-time rate. This makes it suitable for uncontrolled environments such as outdoor smart meters, elevator control panels, and HVAC duct-mounted sensors.
