Product details
Overview
CC2652R1FRGZR from Texas Instruments is a multiprotocol 2.4 GHz wireless microcontroller featuring a 48 MHz Arm® Cortex®-M4F core, 352 kB flash, 80 kB ultra-low-leakage SRAM with parity, -105 dBm Bluetooth 5.2 LE Coded PHY sensitivity, and +5 dBm RF output power. It enables concurrent Thread/Zigbee/Bluetooth 5.2 operation in battery-powered building security sensors and HVAC controllers.
For engineers reviewing the CC2652R1FRGZR datasheet, CC2652R1FRGZR pinout, CC2652R1FRGZR application, or CC2652R1FRGZR equivalent, key selection criteria include its 0.94 µA standby current with full RAM retention, autonomous 4 kB sensor controller, integrated DC/DC converter, 31 GPIOs in VQFN48, and compliance with FCC Part 15, EN 300 328, and ARIB STD-T66.
Technical Context
The CC2652R1FRGZR integrates a dedicated Arm® Cortex®-M0 radio controller for flexible PHY layer handling, enabling simultaneous Bluetooth 5.2 LE, IEEE 802.15.4, and Thread/Zigbee MAC/PHY execution without CPU intervention. Its dual-clock system uses RCOSC_LF/XOSC_LF for RTC and RCOSC_HF for active-mode MCU operation.
Hardware-accelerated cryptography includes AES-128/256, ECC/RSA, SHA2 (up to SHA-512), and TRNG, while the sensor controller operates independently at 2 MHz (30.1 µA) or 24 MHz (808 µA) to offload ADC sampling, capacitive sensing, and environmental monitoring from the main CPU.

FAQ
What wireless protocols does the CC2652R1FRGZR natively support in ROM?
The CC2652R1FRGZR includes Bluetooth® 5.2 Low Energy controller, IEEE 802.15.4 MAC, and TI-RTOS in ROM. Full protocol stacks for Thread, Zigbee®, and TI 15.4-Stack are delivered via the SimpleLink™ LOWPOWER F2 SDK. The CC2652R1FRGZR's Dynamic Multiprotocol Manager enables time-sliced concurrent operation of these protocols on the same hardware without external host processor involvement.
How does the sensor controller in the CC2652R1FRGZR reduce system power consumption?
The CC2652R1FRGZR's autonomous sensor controller runs independently of the main CPU with its own 4 kB SRAM and RISC engine. It can execute low-power sensing tasks-such as 1 Hz ADC sampling-at just 30.1 µA in low-power mode, allowing the Cortex-M4F to remain in deep sleep. This architecture reduces average system current in battery-operated devices like smoke detectors, where the CC2652R1FRGZR achieves 1 µA effective current for periodic sensing.
What are the critical power supply requirements for the CC2652R1FRGZR's VDDR and VDDR_RF rails?
The CC2652R1FRGZR requires tightly regulated 1.68 V supplies on VDDR (digital core) and VDDR_RF (RF section), derived exclusively from the internal DC/DC converter or LDO-no external voltage sources are permitted. These rails must be decoupled per TI's layout guidelines, and VDDR/VDDR_RF must be shorted together on the PCB. Failure to meet this requirement causes unstable RF operation and MCU resets, as confirmed in the CC2652R1FRGZR's power domain specification table.
Can the CC2652R1FRGZR achieve FCC Part 15 certification without custom RF tuning?
Yes-the CC2652R1FRGZR's RF subsystem is pre-characterized for compliance with FCC Part 15, EN 300 328, and ARIB STD-T66 when used with TI-recommended reference layouts and matching networks. Its -105 dBm sensitivity and +5 dBm output meet conducted emission and radiated performance limits out-of-box. However, final system-level certification still requires antenna integration testing, as RF performance depends on board-level parasitics and enclosure effects.
What debugging interfaces does the CC2652R1FRGZR support, and are they accessible in all power modes?
The CC2652R1FRGZR supports 2-pin cJTAG and standard JTAG via pins JTAG_TMSC (24) and JTAG_TCKC (25), both rated for high-drive operation. Debug access remains functional in Active, Idle, and Standby modes but is disabled in Shutdown mode (150 nA). The device also supports SWD over cJTAG, enabling energy-efficient debug sessions during low-power development using tools like TI's XDS110 emulator and Code Composer Studio.
