1 / 71 page  Data Sheet © 2024-2025 Microchip Technology Inc. and its subsidiaries DS70005557C - 1 Introduction The WILCS02IC is a single chip 2.4 GHz and IEEE 802.11b/g/n-compliant solution with integrated High Power Amplifier (HPA), Low-Noise Amplifier (LNA) and Radio Frequency (RF) switches for TX/RX control. It is a Link Controller IC with a hardware-based security accelerator. The WILCS02 is a fully RF and Wi-Fi Alliance®-certified wireless module based on the WILCS02IC. The device provides Secure Digital Input Output (SDIO) or Serial Peripheral Interface (SPI) to interface with the host controller. The WILCS02IC and WILCS02 Module operates at a single supply voltage VDD and VDDIO (3.3V typical). The WILCS02 Module is available with either an on-board Printed Circuit Board (PCB) antenna or U.FL connector for an external antenna. Note: The WILCS02IC must be programmed with the appropriate Link Controller firmware version to meet the specification described in the data sheet. WILCS02IC and WILCS02 Module Features • IEEE 802.11 b/g/n, Single Stream (1x1) 20 MHz Bandwidth WLAN Link – Compatible with Wi-Fi® 6/7 2.4 GHz band • Protected Management Frame (PMF) Handled in Hardware, WPA3 Support • Integrated Power Amplifier (PA), TX/RX Switch and Power Management • Internal Flash Memory (Up to 2 MB) to Store Firmware • Immutable Secure Boot with Hardware Root of Trust • Supports Host-Assisted Firmware Side-Loading • Hardware-Based IEEE 802.15.2 Compliant Three-Wire Packet Traffic Arbitration (PTA) Interface for Wi-Fi/ Bluetooth® Coexistence(2) • SDIO or SPI (SDIO Based SPI; SDIO-SPI) Host Interface on a Supported Linux Host System • Secure Device Firmware Upgrade (DFU) Security • Hardware-Accelerated Security Modes (CryptoMaster) with Built-in Direct Memory Access (DMA) Support – Encryption engines (Advanced Encryption Standard (AES) and Triple Data Encryption Standard (TDES) with different NIST modes of operation): • Modes – Electronic Code Book (ECB), Cypher Block Chaining (CBC), Counter Mode (CTR), Cypher Feedback Mode (CFB) and Output Feedback Mode (OFB) • AES key sizes: 128b, 192b and 256b – Authentication engines: • SHA-1 and SHA-2 www.microchip.com Product Pages: WILCS02IC, WILCS02PE, WILCS02UE WILCS02 Family Data Sheet WILCS02IC and WILCS02 Family |
