1. Production Introduction
1.1 Product Overview
MY_WFM7231 Wi-Fi module is a solution for single-mode Low Energy, in accordance
with 2.4 GHz 802.11b/g/n data transmission protocol. It is truly a SOC solution: the chip
integrates all the software and hardware functions of 802.11b/g/n, covering radio
frequency and MAC layers. The generally used ARM9 MCU and abundant storage resources
enables the chipset to support various network protocols. This module supports SDIO, SPI,
dual UAR, dual 12C and full-speed USB interface. It supports multi-channel ADC input
voltage tests and real-time signal output. A maximum packaging supports 32 GPIO pins.
Rich power management programs are designed internally to realize extremely-low
current under “SOFT-OFF” and “SLEEP” modes, whilst supporting ON-TIME WAKE-UP from
inside out. All the GPIO can be configured as interrupt source, to trigger and wake the
MCU’s up. Our company has developed a full set of solutions that helps to shorten product
development cycle and accelerating the release process.
