PY32MD320K18U7TR

The PY32MD320 series microcontrollers feature a high-performance 32-bit ARM Cortex-M0+ core with a wide voltage operating range. Embedded with up to 64 Kbytes of flash and 8 Kbytes of SRAM, operating at a maximum frequency of 48 MHz. Multiple products are available in various package types. The MCU integrates multiple I2C, SPI, and USART communication peripherals, a 1-channel 12-bit ADC, 5 sixteen-bit timers, and 2 comparators. The PY32MD320 series microcontrollers operate over a temperature range of -40℃~105℃ and a supply voltage range of 1.7 V~5.5 V. The device provides sleep and stop low-power operating modes to meet various low-power application requirements.
