# WINCS02 & RNWF02 — Firmware, Drivers & Tools

Microchip **WINCS02** and **RNWF02** are Wi-Fi network controller devices available via [microchip.com](https://www.microchip.com).

This repository is the central hub for the latest firmware and programming resources:

- [**Firmware Release Packages**](https://github.com/MicrochipTech/WINCS02-RNWF02-Releases/releases) — GitHub releases containing firmware binaries and release notes
- [**Tools**](./tools/) — Tools for programming and updating firmware and files on the devices
- [**Host Driver**](./WINCS02/driver/) — The standalone driver for host MCUs to interface to the **WINCS02** device

## Device Summary
**WINCS02** and **RNWF02** are Wi-Fi network controller devices that offload Wi-Fi and networking from the host MCU or terminal. The host communicates with the module over a simple serial interface — SPI for WINCS02 or UART for RNWF02 — while the module handles 802.11 connectivity, TCP/IP, TLS, MQTT, HTTP, OTA updates, and more.

**WINCS02** and **RNWF02** devices differ from each other in terms of their host interface:

| | WINCS02 | RNWF02 |
|---|---|---|
| **Host Interface** | SPI | UART |
| **Protocol** | Binary TLV (via nc_driver) | ASCII AT Commands |

## Device Features
**WINCS02** and **RNWF02** provide the following features:

- **Wi-Fi:** 802.11 b/g/n, station and soft-AP modes, WPA2/WPA3 Personal & Enterprise, simple roaming
- **TCP/IP Stack:** IPv4/IPv6, TCP, UDP, DHCP client/server, DNS client
- **TLS:** TLS 1.2 client/server
- **MQTT:** MQTT v3.1.1 / v5.0 client with TLS support
- **HTTP/S:** HTTP client for REST APIs and cloud connectivity
- **SNTP:** Network time synchronization
- **Low Power:** Wi-Fi and system level power-save modes
- **Bypass Mode:** Layer 2 raw packet send/receive with unicast/broadcast/multicast filtering
- **Coexistence:** BLE/Wi-Fi coexistence arbiter
- **Internal Flash Memory:** Active and rollback firmware images, per-device calibration data, 60KB on-chip file system
- **File System:** Access to on-chip flash file system (FLFS) for TLS certificates, keys, and configuration files
- **Firmware Programming Options:**
  - **Device Firmware Update (DFU):** Firmware programming of a non-running device
  - **Over-the-air (OTA):** Firmware updates of a running device
- **Secure Boot:** Immutable secure boot with hardware root of trust
- **Anti Rollback:** Protection from historically vulnerable firmware

## Firmware Programming and Updating
Firmware can be programmed or updated on non-running **WINCS02** and **RNWF02** devices:
- via the [DFU tool](./tools/dfu/); or
- via a host application that implements the DFU process described in the application developer guide.

Firmware can be updated on running **WINCS02** and **RNWF02** devices:
- via the [NVM Update tool](./tools/nvm_update/); or
- via a host application that implements OTA as described in the API specification.
