Product details
Overview
CC3135RNMRGKR from Texas Instruments is a dual-band Wi-Fi® network processor IC that offloads 802.11a/b/g/n connectivity (2.4 GHz and 5 GHz) and full TCP/IP stack (IPv4/IPv6) from host MCUs. It integrates an Arm® Cortex®-M3 core, hardware crypto engines (AES, SHA, RSA), FIPS 140-2 Level 1 certification, and supports 16 secure TLS v1.2 sockets - enabling secure, low-power IoT edge nodes in HVAC systems and video doorbells.
For engineers reviewing the CC3135RNMRGKR datasheet, CC3135RNMRGKR pinout, CC3135RNMRGKR application, or CC3135RNMRGKR equivalent, key selection criteria include dual-band RF performance (–96 dBm RX sensitivity @ 2.4 GHz), ultra-low hibernate current (4 µA), integrated DC/DC regulators for 2.1–3.6 V operation, and antenna selection GPIO support for optimized RF layout.
Technical Context
The CC3135RNMRGKR implements a dedicated Wi-Fi subsystem with separate execution environments for networking and security, isolating host MCU firmware from protocol stack vulnerabilities. Its RF architecture includes dual-band transceivers with integrated diplexer/SPDT switch control, BLE coexistence signaling via dedicated DIOs, and configurable antenna selection using 13 GPIOs.
Power management is hardware-assisted: integrated DC/DC converters supply VDD_PA_IN, VDD_DIG1, and VDD_ANA1 rails; low-power modes include shutdown (1 µA), hibernate (4 µA), and LPDS (120 µA) with retained RAM and secure context. The device boots from internal ROM and executes Wi-Fi firmware independently of host MCU timing.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Wi-Fi network processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CC3235SFARGKR | Integrated 1 MB flash and 256 KB RAM; adds secure boot, file system security, and cloning protection not present in CC3135RNMRGKR. | Required when application firmware must run directly on Wi-Fi SoC instead of external MCU; unsuitable for host-processor-offload architecture. | Select CC3235SFARGKR only if migrating from network processor to wireless MCU model with self-contained application execution. |
| ESP32-WROVER-E | No FIPS 140-2 certification; lacks hardware-accelerated TLS 1.2; uses external flash; 2.4 GHz only; no 5 GHz support. | Suitable for cost-sensitive consumer IoT where regulatory security validation is not required and dual-band operation is unnecessary. | Choose ESP32-WROVER-E for prototyping or non-regulated applications where BOM cost is prioritized over certification and 5 GHz performance. |
Compared with CC3235SFARGKR, CC3135RNMRGKR offers lower system-level power consumption and simpler host integration but requires external flash and lacks on-chip application memory.

FAQ
What is the primary function of the CC3135RNMRGKR in an embedded system?
The CC3135RNMRGKR serves as a dedicated Wi-Fi network processor that offloads all 802.11a/b/g/n protocol stack, TCP/IP (IPv4/IPv6), TLS encryption, and internet application layers (HTTPs, mDNS, DNS-SD) from the host MCU. In a typical implementation, the host MCU communicates with CC3135RNMRGKR via SPI or UART to initiate connections, send/receive data through BSD sockets, and manage security credentials - freeing the host to focus on application logic.
Does the CC3135RNMRGKR support both 2.4 GHz and 5 GHz Wi-Fi bands simultaneously?
Yes, the CC3135RNMRGKR supports simultaneous dual-band operation per IEEE 802.11a/b/g/n: 2.4 GHz (802.11b/g/n) and 5 GHz (802.11a/n). It can operate as Station (STA), Access Point (AP), or Wi-Fi Direct® (2.4 GHz only) on either band. The RF architecture includes separate A-band (5 GHz) and BG-band (2.4 GHz) paths with integrated diplexer and SPDT switch control, allowing concurrent or selective band usage based on environmental conditions and application needs.
What power-saving features does the CC3135RNMRGKR offer for battery-powered designs?
The CC3135RNMRGKR provides multiple hardware-managed low-power states: shutdown (1 µA), hibernate (4 µA with full context retention), and low-power deep sleep (LPDS) at 120 µA with RAM retention. Its integrated DC/DC converters optimize efficiency across 2.1–3.6 V input, and the "always," "intermittent," and "tag" power profiles allow fine-grained control over wake intervals and radio duty cycling. These features enable multi-year operation on coin-cell or Li-SOCl₂ batteries in applications like wireless sensors and smart locks.
How is security implemented in the CC3135RNMRGKR beyond standard WPA2/WPA3?
Beyond WPA2/WPA3 Personal and Enterprise, the CC3135RNMRGKR implements multilayered security including FIPS 140-2 Level 1–certified hardware crypto engines (AES, SHA, RSA), secure boot with signature verification, unique per-device key pair generation, software tamper detection, certificate signing request (CSR) support, and online certificate status protocol (OCSP) validation. It enforces separate execution environments for networking and application code, isolates device identity and keys in protected memory, and supports initial secure programming during manufacturing - meeting stringent requirements for medical, grid, and industrial IoT.
What interfaces does the CC3135RNMRGKR use to communicate with a host microcontroller?
The CC3135RNMRGKR supports two primary host interfaces: SPI (HOST_SPI_CLK, HOST_SPI_MOSI, HOST_SPI_MISO, HOST_SPI_nCS) and UART (UART1_RX, UART1_TX, UART1_nCTS, UART1_nRTS). SPI is the recommended interface for production systems due to higher throughput (up to 20 MHz) and deterministic timing; UART is typically used for development, debugging, and Flash programming. Both interfaces are managed by TI's slim host driver, which is portable across 8-/16-/32-bit MCUs and OS-agnostic.
