Product Introduction：

The PY32F040 microcontrollers incorporate the high-performance ARM® 32-bit Cortex®-M0+ core operating at up to 72 MHz frequency, embedded memories with up to 128 KB Flash and 16 KB SRAM, andcontains various products in different package types. The chip integrates multi-channel I2C, SPI, USARTand other communication peripherals, one 12-bit ADC, 13 timers, two comparators, two operational amplifiers, and one LCD driver.The PY32F040 microcontrollers operate in the temperature range from -40 to 85 °C or -40 to 105 °C, andthe operating voltage range is 1.7 ~ 5.5 V. Two low-power operating modes, namely Sleep mode and Stopmode are provided, which can meet different low-power applications.These features make the PY32F040 microcontrollers suitable for a wide range of applications such ascontrollers, portable devices, PC peripherals, gaming and GPS platforms, industrial applications.
