Product details
Overview
CC3200R1M2RGCR from Texas Instruments is a Wi-Fi CERTIFIED single-chip wireless MCU integrating an ARM Cortex-M4 core (80 MHz), dedicated Wi-Fi network processor, 256KB RAM, hardware crypto engine (AES-256, SHA2, TLS/SSL), and support for Station/AP/Wi-Fi Direct modes - enabling secure cloud-connected IoT endpoints in home automation and industrial control.
For engineers reviewing the CC3200R1M2RGCR datasheet, CC3200R1M2RGCR pinout, CC3200R1M2RGCR application, or CC3200R1M2RGCR equivalent, key selection criteria include integrated TCP/IP stack, dual-band Wi-Fi throughput (13 Mbps TCP / 16 Mbps UDP), low-power hibernate mode (4 µA), QFN-64 package with 9 mm × 9 mm footprint, and on-chip ROM bootloader with peripheral drivers.
Technical Context
The CC3200R1M2RGCR implements a dual-subsystem architecture: an applications MCU subsystem (ARM Cortex-M4 @ 80 MHz) handles user firmware and peripherals (UART, SPI, I2C, ADC, McASP, SD/MMC), while a fully autonomous Wi-Fi network processor subsystem (dedicated ARM core) executes Wi-Fi MAC/baseband, 802.11 b/g/n radio, TCP/IP, TLS/SSL, and supplicant stacks entirely in ROM - eliminating host MCU intervention during Wi-Fi operations.
Power management integrates DC-DC converters supporting 2.1–3.6 V VBAT input, with hibernate (4 µA), LPDS (250 µA), and active RX/TX current profiles (59 mA / 229 mA at 54 OFDM). Clocking uses a 40-MHz crystal for WLAN and optional 32.768-kHz RTC crystal, with all digital I/Os configurable for 2/4/6 mA drive strength and 10-µA pull-up/down.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M4 running at 80 MHz - enables real-time sensor processing and protocol stack execution without external MCU. |
| Wi-Fi Compliance | Wi-Fi CERTIFIED™ 802.11 b/g/n - guarantees interoperability and regulatory compliance for global deployment. |
| RAM Capacity | 256KB embedded SRAM - sufficient for concurrent application code, Wi-Fi buffers, and TLS handshake state storage. |

| Package | 64-pin QFN, 9 mm × 9 mm, 0.5-mm pitch - supports compact PCB layout with thermal pad for RF stability. |
| Operating Temp | –40°C to +85°C ambient - qualified for industrial and consumer environments without derating. |
| Low-Power Mode | Hibernate current ≤4 µA with RTC active - enables battery-powered sensors with multi-year operation. |
Pinout & Package
CC3200R1M2RGCR is housed in a 64-pin QFN package (9 mm × 9 mm, 0.5-mm pitch) with exposed thermal pad. Pin functions are highly multiplexed; configuration is controlled via register settings and hardware reset states. All digital I/Os support programmable drive strength (2/4/6 mA) and 10-µA pull-up/down.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| nRESET | Global master reset input | Active-low asynchronous reset; must be held low until VBAT is stable to prevent unintended boot. |
| FLASH_SPI_CLK/DIN/DOUT/CS | Dedicated serial flash interface | Fixed-function pins for external SPI flash boot - no software reconfiguration required. |
| WLAN_XTAL_P/N | 40-MHz WLAN crystal connection | Differential input for primary RF clock; requires external 40-MHz crystal with load capacitance matching. |
| RTC_XTAL_P/N | 32.768-kHz RTC crystal interface | Supports low-power real-time clock operation during hibernate with external crystal or CMOS clock source. |
| ANTSEL1/ANTSEL2 | Antenna selection control | Digital outputs for RF front-end antenna switching - enables diversity or dual-band antenna configurations. |
| VDD_PA_IN / DCDC_PA_OUT | PA power supply path | Separate analog rail for power amplifier; supports internal DC-DC conversion from VBAT for optimized RF efficiency. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Wi-Fi Network Processor | Dedicated ARM MCU offloads full 802.11 b/g/n MAC, TCP/IP, TLS/SSL, and supplicant - frees main CPU for application logic. |
| Secure Boot & Firmware Validation | ROM-based bootloader verifies signed firmware images using SHA256 and RSA-2048 before execution - prevents unauthorized code injection. |
| Parallel Camera Interface | 8-bit pixel clock and data lines (pCLK, pHS, pVS, pDATA[0:7]) - enables direct connection to CMOS image sensors without external bridge IC. |
| Multi-Protocol Connectivity | Simultaneous support for 8 TCP/UDP sockets and 2 TLS/SSL sockets - allows concurrent cloud MQTT, HTTP, and local BLE-to-Wi-Fi bridging. |
| Smart Provisioning | SmartConfig™, AP mode, and WPS 2.0 - simplifies Wi-Fi credential setup for end users without exposing SSID/password in firmware. |
Applications
| Home Automation Gateway | Industrial Wireless Sensor Node |

Equivalent & Alternatives
The following parts are listed as comparable options for similar wireless MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESP32-WROOM-32 | 2.4 GHz dual-core Xtensa LX6, 4MB flash, no integrated crypto accelerator for TLS - relies on software stack. | Higher raw throughput but higher active current (80 mA RX); lacks Wi-Fi CERTIFIED status and ROM-based secure boot. | Prefer CC3200R1M2RGCR when regulatory certification, hardware crypto, or deterministic low-power hibernate is mandatory. |
| RTL8720DN | ARM Cortex-M23 @ 200 MHz, 2MB flash, supports 802.11 b/g/n + Bluetooth 5.0, but no dedicated network processor - Wi-Fi stack shares CPU resources. | Lower cost and smaller QFN-48 package, but TLS handshake latency varies with application load due to shared CPU. | Prefer CC3200R1M2RGCR when deterministic Wi-Fi timing, guaranteed hibernate current, or TI's long-term industrial support is required. |
Compared with ESP32-WROOM-32 and RTL8720DN, the CC3200R1M2RGCR delivers predictable low-power behavior through its isolated Wi-Fi subsystem and hardware crypto, making it suitable for safety-critical or battery-constrained deployments where stack interference or certification gaps are unacceptable.

FAQ
What is the maximum TCP throughput achievable with the CC3200R1M2RGCR?
The CC3200R1M2RGCR achieves up to 13 Mbps TCP throughput under standard 54 OFDM conditions, as measured per TI application note SWAS032F. This performance is enabled by the dedicated Wi-Fi network processor and hardware TCP/IP stack - no host MCU involvement is required during data transfer, preserving CPU cycles for application tasks.
Does the CC3200R1M2RGCR support WPA2 Enterprise security?
Yes, the CC3200R1M2RGCR supports WPA2 Enterprise security including EAP-TLS and PEAP-MSCHAPv2 authentication protocols. This capability is implemented in ROM within the Wi-Fi network processor subsystem, ensuring consistent, certified behavior without requiring application-layer implementation or patching.
Can the CC3200R1M2RGCR operate from a single 3.3-V supply?
No - the CC3200R1M2RGCR requires a 2.1–3.6 V VBAT supply, with VIO internally tied to VBAT. It does not accept a fixed 3.3 V rail directly; instead, it uses integrated DC-DC converters to generate internal analog and digital voltages. External LDOs or buck regulators must comply with the recommended operating conditions in Section 4.4 of SWAS032F.
How many general-purpose I/O pins does the CC3200R1M2RGCR provide?
The CC3200R1M2RGCR provides up to 27 individually programmable, multiplexed GPIO pins (GPIO0–GPIO32, excluding reserved/NC pins). Each supports configurable drive strength (2/4/6 mA), 10-µA pull-up/down, and wakeup capability from hibernate - verified in Table 3-1 of the official datasheet SWAS032F.
Is external serial flash memory required for CC3200R1M2RGCR operation?
Yes - external serial flash is mandatory for storing application firmware, file system, and certificates. The CC3200R1M2RGCR boots from external SPI flash via dedicated FLASH_SPI_* pins; internal ROM contains only the bootloader and peripheral drivers, not user application code.
