The GD32A513KBU3 from GigaDevice Corporation is a Microcontroller that is ideal for BCM, HVAC, BMS, on-board chargers, automotive radar, automotive vision, DC-DC converters, automobile instruments, and in-vehicle infotainment (IVI) applications. It requires an input voltage of 2.7-5.5 V. This microcontroller unit (MCU) incorporates a 32-bit ARM Cortex-M33 processor, 384 KB on-chip Flash memory, 48 KB SRAM, 2 12-bit A/D converters, a D/A converter, comparator, 16-bit timer, 2 basic timers, 4, pulse width modulation (PWM ) advanced timers, and serial/peripheral interfaces. The processor core offers low-cost debugging operations along with several power-saving modes to provide optimization between low interrupt latency and power consumption, making this MCU suitable for high-performance and low-power applications. 

The MCU’s core is based on the ARMv8 architecture that supports a powerful and scalable instruction set enabling advanced digital signal processing (DSP) and bit field manipulation. This microcontroller can be controlled via SPI, I2C, USART, I2S, and CAN interfaces and has a DMAMUX interface for multi-function communication. It has low-voltage and over-voltage detectors for monitoring the power supply to ensure safety during operation. This MCU is available in a surface-mount package 5 x 5 mm.
