Introduction：

PY32T020 Series are based on a 32-bit ARM® Cortex®-M0+ core and operates at up to 48 MHz with a wide voltage range. It integrates up to 32 KB Flash and 4 KB SRAM, available in multiple package options. The device integrates I2C, SPI, UART and other communication peripherals. It has one 12-bit ADC, two 16-bit timers, two comparators and 26-channel low-power dual-mode capacitive touch circuit (in Stop mode).The PY32T020 microcontrollers operate across a temperature range of -40 to 105 °C and a standard voltage range of 1.8 - 5.5 V, providing

Sleep/Stop/Deep_stop/Hibernate low-power operating modes for different low-power applications.The PY32T020 series feature excellent touch button characteristics. Coupled with its outstanding antiinterference performance, it can be adapted in various solutions. Its applications span smart appliances, controllers, handheld equipment, PC peripherals, gaming/GPS platforms, and industrial systems.
