1. Product overview
HM-WF8266WiFi module, developed by HOPERF Microelectronics Co., Ltd., provides a highly
integrated Wi-Fi SoC solution with low power consumption, compact design and high stability
to meet the needs of users.
HM-WF8266WiFi module has a complete and self-contained Wi-Fi network function, which can
be used independently and run as a slave plane mounted on other host MCUs. When
HM-WF8266 is used independently, it can be booted directly from external flash.
HM-WF8266WiFi module,built-in high-speed buffer memory is conducive to improving system
performance and optimizing storage system. In addition, HM-WF8266 can be used as Wi-Fi
adapter only through SPI/SDIO interface or I2C/UART interface, and can be applied to the
design of any microcontroller.
HM-WF8266 WiFi module integrates antenna switch, radio frequency balun, power amplifier,
low noise amplifier, filter and power management module. This compact design requires very
few external circuits and minimizes the size of the PCB.
HM-WF8266 also integrates an enhanced version of the Tensilica's L106 diamond series 32-bit
core processor, with on-chip SRAM main frequency support of 80 MHz and 160 MHz, and RTOS
support. HM-WF8266 can use GPIO external sensors and other devices to achieve the
minimum system resources in the early development and operation.
Advanced Features
1.Quickly switch between sleep mode and wake-up mode in the power-saving status. It has the
characteristics of adaptive radio bias, front-end signal processing, fault removal and
coexistence of radio system. Avoid interference from cellular/Bluetooth/DDR/LVDS/LCD.
2.Multiple sleeping mode to switch to adapt the different low-consumption environments
3.Perfect peripheral circuit, 4-layers, good impedance matching and better signal output;
remarkable in terms of stability and anti-jamming ability;the PCB antenna tested & certificated
by professional Labs and RoHS approved.
4.Customized design and support further developments based on customer needs, such as:
Docking different cloud servers,design special solutions for customers, change Flash storage to
4M/8M/16M, etc.
