The WG228 wifi module is a low-power consumption IEEE 802.11 b/g/n IoT (Internet of Things) module, which is specifically optimized for low power IoT applications. This module features small form factor (21.7mm x14.7mm x 2.1mm) while fully integrating Power Amplifier (PA), Low Noise Amplifier (LNA), Transmit/Receive(T/R), switch, power management, and PCB antenna. With advanced security, it is interoperable with various vendors using IEEE 802.11b/g/n Access Points in wireless LAN. The module provides Serial Peripheral Interface (SPI) and Secure Digital Input Output (SDIO) to interface with the host controller.
Features：
◆Compliant with IEEE 802.11 b/g/n 20 MHz (1x1) solution
◆ Supports Single spatial stream in 2.4 GHz ISM band
◆Integrated Power Amplifier (PA) and Transmit/Receive (T/R) switch
◆ Superior sensitivity and range through advanced PHY signal processing
◆Advanced equalization and channel estimation
◆Advanced carrier and timing synchronization
◆Wi-Fi Direct® and Soft-AP support
◆ Supports IEEE 802.11 WEP, WPA, WPA2 and WPA2-Enterprise security
◆ Superior Medium Access Control (MAC) throughput through hardware accelerated twolevel A- MSDU/A-MPDU frame aggregation and block acknowledgement
◆On-chip memory management engine to reduce the host load
◆ SPI and SDIO host interfaces
◆ Operating temperature ranges from -40°C to +85°C
◆Input/Output operating voltage of 1.8V to 3.6V
• Power-save modes:
– <1µA Power-Down mode typical at 3.3V I/O
– 380µA Doze mode with chip settings preserved (used for beacon monitoring)
– On-chip low power Sleep oscillator
– Fast host wake-up from Doze mode by a pin or the host I/O transaction
◆Wi-Fi Alliance® certified for connectivity and optimizations
