The GMF03x series microcontrollers(GMF03x MCU or GMF03x), with ARM® Cortex®-M0 core, is a MCU product with high performance and low power consumption. The standby power consumption is as low as 2 µA. The GMF03x MCU is embedded with 4 Kbytes of SRAM and 32 Kbytes of Flash, and high-precision RC oscillators, with the supported operating frequency up to 48MHz. The GMF03x MCU also supports abundant peripheral interfaces, including push-pull/open-drain GPIOs, serial peripheral interface(SPI), I2C with Fast-mode Plus(Fm+), universal synchronous/asynchronous receiver/transmitter(USART), inter-IC sound interface(I2S). It also has 12-bit ADC with the conversion rate up to 1Msps, 5 timers supporting comparison and capture functions, a high-precision RTC with clock self-calibration, 24-channel of touch sensor controllers (TSC) and 2 independent operational amplifiers (OPAMP).
All of these make the GMF03x MCU an ideal choice for electric bicycle controllers, air quality monitors, smart traffic/city/home devices and consumer devices with touch keys.
