Product Introduction：

The PY32L020 incorporates the high-performance ARM® 32-bit Cortex®-M0+ core operating at up to 48MHz frequency,embedded memories with up to 24 KB Flash and 3 KB SRAM, available in multiple packageoptions. The PY32L020 integrates I2C, SPI, USART and other communication peripherals, one 12-bit ADC,two 16-bit timers, and two comparators.The PY32L020 operates in the -40 - 85°C or -40 - 105 °C temperature ranges from a 1.7 to 5.5 V powersupply. The PY32L020 provides Sleep/Stop/Deep_stop low-power operating modes for different low-powerapplications.These features make the PY32L020 suitable for a wide range of applications such as controllers, portabledevices, PC peripherals, gaming and GPS platforms, as well as industrial applications.
