Introduction:

The PY32T020-B series are based on a 32-bit ARM® Cortex®-M0+ core and operates at up to 48 MHzwith a wide voltage range. It integrates up to 32 KB Flash and 4 KB SRAM, available in multiple packageoptions.The PY32T020-B series integrate I2C, SPI, UART and other communication peripherals. It has one 12-bitADC, two 16-bit timers, two comparators and 26-channel low-power dual-mode capacitive touch circuit (inStop mode).The PY32T020-B microcontrollers operate across a temperature range of -40 to 105 °C and a standardvoltage range of 1.8 to 5.5 V. provides Sleep and Stop low power operating modes, which can meet differentlow-power applications.The PY32T020-B series feature excellent touch key controller. Coupled with its outstanding anti-interference performance, it can be adapted in various solutions. Its applications span smart appliances, controllers,handheld equipment,PC peripherals,gaming,GPS platforms, and industrial systems.
