QFN 5X5-32L

AW32F020QNR-Q1 is a chip designed specifically for automotive window motor controllers, which can improve the convenience of debugging automotive window controls. The AW32F020QNR-Q1 integrates a 32-bit MCU. The MCU provides superior computational performance and an efficient interrupt system, while the peripheral devices use a smaller number of pins and lower power consumption. AW32F020QNR-Q1 integrates 64KB FLASH memory with erase/write protection function. The LIN communication module is integrated to support the transceiver function of LIN communication. Integrated 12-bit ADC for LED junction voltage and temperature detection, supporting 13 channels, VREF voltage can be configured to 1.2V/2.4V/3.3V. Support 4 current sinks, the maximum current of each channel is up to 60mA. Support 16-bit PWM dimming, support 80Hz~250Hz dimming frequency. Two basic timers and one WDT are integrated. 12 general GPIO ports are integrated to support PWM mode and external LIN receiver interconnection. The SWD debug interface is integrated with built-in Power on Reset (POR) and Brown out Reset (BOR) functions to effectively protect the chip. AW32F020QNR-Q1 is packaged in WBQFN 5x5-32L.
