The GD32A503RDT3 from GigaDevice Semiconductor is a Microcontroller that is ideal for on-board chargers, BCM, HVAC, battery management systems, automotive radar, automotive vision, DC-DC converter, and in-vehicle infotainment applications. It requires a clock speed of up to 100 MHz. This microcontroller unit (MCU) consists of a 32-bit ARM Cortex-M33 core with 384 KB flash and 48 KB SRAM, 12-bit A/D converters, D/A converter, a comparator, 16-bit timer, basic timers, pulse width modulation (PWM) timers, and interfaces. The built-in processor is based on the ARMv8 architecture and can perform scalable instruction set computations, including general data processing I/O control tasks, advanced bit field manipulations, and digital signal processing.

This MCU also provides various other functions such as trigger selection, DMA memory request multiplexer, and multi-function communication via special interfaces – SPI, I2C, UART, USART, I2S, and CAN. It supports power-saving modes to optimize power between wakeup latency and power consumption, which is an essential factor for low-power applications. This microcontroller is available in a surface-mount package that measures 12.2 x 12.2 mm.
