CMS32F033QN32 32‑Bit MCU Microcontroller QFN32 for consumer electronics

The CMS32F033 series is a line of enhanced MCUs based on the ARM Cortex-M0 core, launched by Cmsemicon. Key specifications include a maximum operating frequency of 64 MHz, an operating voltage range of 2.1V–5.5V, 32 KB of Flash memory, and 8 KB of SRAM. The series features up to 30 GPIOs, a built-in 32-bit hardware multiplier/divider, a high-speed 12-bit ADC, PWM, comparators, programmable gain amplifiers (PGAs), operational amplifiers (op-amps), and a wide range of communication interfaces.
