Holtek's HT32F52331 is a LQFP-48_7x7x05P RoHS integrated circuit. It is a 32-bit ARM® Cortex™-M4 based MCU, using a memory-mapped architecture that allows microcontrollers to read and write data to specific memory addresses. It features a wide operating frequency range, a large Flash memory, and multiple communication interfaces. It is suitable for automotive, healthcare, and industrial applications. The device comes with a rich set of analog peripherals, including a 16-channel 10-bit ADC, a PWM controller, an encoding timer, and multiple voltage comparators. It also has a DMA controller for handling large data movements efficiently. The HT32F52331 operates from 0 to 48MHz and supports power-saving modes, with a power-down current as low as 20uA. It also has built-in clock and power management, allowing for lower power consumption and higher system integration.
