Product Overview

CS32F03X-RA series microcontrollers adopt the high-performance 32-bit ARM ® Cortex ®- M0 core and include the CS32F030-RA and CS32F031-RA series. They have 64 KB embedded flash and 8 KB SRAM, and maximum operating frequency of 48 MHz. The CS32F03X-RA series includes 20 to 48 pins and other products. The chip has standard communication interfaces (I2C, SPI, and USART), one 12-bit ADC, five 16-bit universal timers, and one enhanced control PWM timer. The operating temperature range of the CS32F03X-RA series microcontroller is -40 ℃~85 ℃, and the operating voltage range is 2 V~5.5 V. The chip provides several power operation modes to meet different low-power applications. The CS32F03X-RA series microcontrollers are used in a variety of application scenarios, such as smart homes, handheld devices, consumer electronics, industrial control, and GPS platforms.
