The gaming mechanical keyboard is a high-end game peripheral. Each key is controlled to close by an independent switch. With a clear key range and high sensitivity, it is suitable for game, office, and other scenarios.

In recent years, the global electronic sports industry has developed rapidly. Electronic sports fans are keen to "pay" for professional game peripherals such as high-performance keyboard and mouse, headset phonetic equipment, and high-resolution curved screen. Among them, the gaming mechanical keyboard is highly sought after by professional players with its high-quality operation hand feeling, and gaming experience. According to the Huajing Industrial Research Institute, the mechanical keyboard market size in 2014-2018 with a compound annual growth rate of 26.7%, from RMB 570 million to RMB 1.46 billion, is expected to reach RMB 2.11 billion in 2021.

APM32F072xB Series MCU Gaming Mechanical Keyboard Solution

Geehy 32-bit industrial-grade extended APM32F072xB series MCU has high integration, low power, and strong extended control function. The operating frequency is 48MHz, the voltage range is 2.0V~3.6V, the Flash is 64-128KB and SRAM is 16KB. The operating temperature is -40℃~+105℃. QFN48 and LQFP48/64/100 packages can be provided.

APM32F072xB can provide the following functions for peripheral devices of electronic games such as mechanical keyboard/mouse/controller.

Fast Response & Easy Development

Compared with the traditional 8-bit MCU keyboard solution, the APM32F072xB series based on Arm® Cortex®-M0+ core can realize a more complex user-defined programming algorithm and support real-time response control with a high return rate and no delay. At the same time, it has excellent portability and can provide a convenient general development environment, which helps to reduce the workload of engineers, and accelerate the development and marketing of application schemes.

Intelligent Anti-Shake & Efficient Operation

 TSC function is added, and it can be used for proximity, touch key, linear or rotary sensors. It supports power-on/power-down reset. A programmable voltage monitor is built in. VBat supports RTC and backup register power supply and supports up to 87 I/Os, all of which can be mapped to external interrupt vectors, which helps to collect a large number of key signals, reduce the amplitude of waveform oscillation, and realize the intelligent anti-shake of the game mechanical keyboard.

Full-speed USB module supports operation without an external crystal oscillator, thus reducing the system cost.

 The embedded full-speed USB2.0 interface supports BCD and LPM. The customer does not need to consider the external crystal oscillator application circuit in the design, which is conducive to saving component cost and PCB space, improving pin utilization, and avoiding problems in the processing process (The cost-sensitive customers can select the tailored APM32F071xB and APM32F070xB series).

Certified USB-IF, which effectively guarantees no worry about the export of end products

 The built-in 7-channel DMA controller, five 16-bit general-purpose timers, and one 16-bit advanced timer are used for infrared control decoding or DAC control, and can easily realize LED light strips, RGB full-color backlight, and other light modes. At the same time, this series of chips have passed the compatibility test, meet the quality requirements of USB devices, certified the USB-IF, and meet the export needs of customer terminal products.
