HOLTEK HT32F57352-64LQFP

This series of microcontrollers are 32-bit high-performance, low-power MCUs based on the Arm Cortex-M0+ processor core. The Cortex-M0+ is a next-generation processor core that tightly integrates the Nested Vectored Interrupt Controller (NVIC), SysTick Timer, and advanced debug support.

This series of MCUs can operate at frequencies up to 60 MHz, leveraging a Flash accelerator for enhanced performance. They provide up to 128 KB of embedded Flash memory for program/data storage and up to 16 KB of embedded SRAM for system operations and application use. This series of MCUs features a wide range of peripherals, including USB2.0 FS, PDMA, AES-128, hardware divider DIV, SPI, I2S, USART, UART, SCI, I2C, GPTM, PWM, SCTM, BFTM, CRC-16/32, RTC, WDT, ADC, CMP, DAC, LCD, and SW-DP (Serial Wire Debug Port). Several power-saving modes are provided, offering optimized flexibility in terms of wake-up latency and power consumption — a key consideration for low-power applications.
