Product details
Overview
CC3220MODSF12MOBR from Texas Instruments is a FCC/CE/SRRC-certified Wi-Fi® wireless MCU module integrating dual Arm® Cortex®-M4 and network processor subsystems, 1MB on-board SPI Flash, 256KB RAM, and hardware crypto acceleration for TLS 1.2 and WPA3 security-designed for secure, low-power IoT edge nodes requiring embedded web server and RESTful API support.
For engineers reviewing the CC3220MODSF12MOBR datasheet, CC3220MODSF12MOBR pinout, CC3220MODSF12MOBR application, or CC3220MODSF12MOBR equivalent, key selection factors include integrated Flash memory size, QFM-63 industrial-grade packaging, dual-MCU architecture with autonomous Wi-Fi stack offload, and certified 2.4-GHz 802.11b/g/n operation with IPv4/IPv6 dual-stack support.
Technical Context
The CC3220MODSF12MOBR implements physically isolated execution environments: an 80-MHz Arm® Cortex®-M4 MCU for user applications and a dedicated ROM-based network processor handling Wi-Fi MAC/PHY, TCP/IP (IPv4/IPv6), TLS/SSL, and HTTP(S) server logic-enabling concurrent application execution and network processing without software co-scheduling.
Its power-management subsystem integrates a DC/DC converter supporting 2.3–3.6 V input, delivering 1 µA shutdown, 5 µA hibernate, and 135 µA LPDS modes with 256KB RAM retention-while RF performance delivers –95.0 dBm RX sensitivity at 1 DSSS and 17.0 dBm TX output at same modulation.

Pinout & Package
CC3220MODSF12MOBR uses a 63-pin QFM package (20.5 mm × 17.5 mm, 1.27-mm pitch) with exposed thermal pad. All pins are surface-mount compatible and designed for reflow assembly on standard FR-4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1,2,16,27,28,30,32,38,43) | Ground reference | Multiple dedicated ground pins ensure low-impedance return paths for analog, digital, and RF sections |
| VBAT1 (Pin 37), VBAT2 (Pin 40) | Main power supply | 2.3–3.6 V input pins-must be connected to common system rail; internal DC/DC converter supplies all internal domains |
| RF_BG (Pin 31) | 2.4-GHz RF I/O | Primary antenna interface-requires 50-Ω matched trace to external antenna or RF connector |
| nRESET (Pin 35) | Active-low reset input | Asynchronous hard reset; internal 100-kΩ pull-up to VBAT_RESET-connect VBAT_RESET to VBAT if host cannot guarantee defined state |

Equivalent & Alternatives
The following parts are listed as comparable options for similar wireless MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CC3220MODASF12MONR | Same CC3220SF12ARGK die but includes integrated PCB antenna and larger 25.5 mm × 20.5 mm footprint | Eliminates external antenna design and matching network; suited for space-constrained consumer devices | Select when antenna integration and reduced BOM outweigh PCB area increase |
| ESP32-WROVER-E | 2.4 GHz Wi-Fi + Bluetooth 4.2/5, dual-core Xtensa LX6, 4MB PSRAM + 4MB Flash, no built-in crypto acceleration for TLS 1.2+ or secure boot | Requires external security co-processor or software TLS stack; higher peak current (240 mA TX) limits battery use | Select when Bluetooth coexistence or lower unit cost is prioritized over regulatory certification and hardware security |
Compared with CC3220MODASF12MONR, CC3220MODSF12MOBR offers smaller PCB area and external antenna flexibility; versus ESP32-WROVER-E, it delivers pre-certification, hardware-accelerated WPA3/TLS, and ultra-low 135 µA LPDS-making it superior for secure, battery-operated industrial edge nodes.

FAQ
What is the primary function of the CC3220MODSF12MOBR in an IoT system?
The CC3220MODSF12MOBR serves as a self-contained wireless MCU module that executes both application firmware and full Wi-Fi/Internet protocol stacks independently-enabling IoT edge devices to connect securely to cloud services, run local web servers, and manage sensors without external host processors or radio components. Its dual-MCU architecture ensures deterministic real-time response while maintaining robust network connectivity.
Does the CC3220MODSF12MOBR require an external antenna?
Yes, the CC3220MODSF12MOBR requires an external 2.4-GHz antenna connected to the RF_BG pin (Pin 31). Unlike the CC3220MODASF12MONR variant, it does not integrate a PCB antenna-allowing designers to select optimized antennas (e.g., chip, ceramic, or u.FL-compatible) based on mechanical constraints and RF performance targets.
How does the CC3220MODSF12MOBR support secure firmware updates?
The CC3220MODSF12MOBR supports secure over-the-air (OTA) updates through its hardware-accelerated crypto engine, secure boot validation, and encrypted file system. Firmware images are authenticated using SHA2-256 and decrypted with AES-256 before loading-ensuring integrity and confidentiality. The CC3220MODSF12MOBR also provides APIs for signed image verification and rollback protection during update sequences.
What power supply voltage range is supported by the CC3220MODSF12MOBR?
The CC3220MODSF12MOBR operates from a single 2.3 V to 3.6 V supply applied to VBAT1 (Pin 37) and VBAT2 (Pin 40). Its integrated DC/DC converter regulates internal voltages, enabling stable operation across this range-making it compatible with lithium coin cells, Li-ion batteries, and regulated 3.3-V rails. The module draws only 1 µA in shutdown mode, ideal for energy-harvesting or long-life battery applications.
Can the CC3220MODSF12MOBR operate as both a Wi-Fi station and access point simultaneously?
No, the CC3220MODSF12MOBR supports station, access point, and Wi-Fi Direct® modes-but not concurrently. It can function as a station connecting to an upstream router, or as an AP hosting up to four client stations, or as a Wi-Fi Direct group owner. Mode selection is configured at runtime via the SimpleLink SDK; switching between modes requires a soft reset and reinitialization of the Wi-Fi subsystem.
