The GD32A513VBT3 from GigaDevice Semiconductor is an EV ECU that is ideal for BCM, HVAC, battery management systems, on-board chargers, automotive radar, automotive vision, DC-DC converters, and in-vehicle infotainment applications. It requires an input voltage of 2.7-5.5 V and has a power dissipation of 441 mW. This microcontroller unit (MCU) incorporates a 32-bit ARM Cortex-M33 processor with 128 KB flash, 48 KB SRAM, 12-bit A/D converters, a D/A converter, a comparator, 16-bit timer, basic timers, pulse width modulated (PWM) timers, and interfaces. The ARM 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 (DSP).

This EV ECU can perform multiple functions via special interfaces such as trigger selection controller (TRIGSEL), DMA request multiplexer, and multi-function communication interface (MFCOM). It can be communicated and controlled with an external host device through SPI, I2C, USART, I2S, and CAN interfaces. This MCU supports several power-saving modes to provide the flexibility for maximum optimization between wakeup latency and power consumption, essential for low-power applications. It is available in an LQFP100 surface-mount package that measures 16.20 x 16.20 x 1.60 mm.
