The GD32E502 product series incorporates the Arm^® Cortex^®-M33 32-bit processor core operating at up to 100 MHz frequency. It provides up to 384 KB on-chip Flash memory and up to 48 KB SRAM. An extensive range of enhanced I/Os and peripherals are connected to two APB buses. The product series offers two 12-bit ADCs, one DAC, one comparator, up to one general 16-bit timer, two basic timers, four PWM advanced timers, as well as standard and advanced communication interfaces: up to two SPIs, two I2Cs, three USARTs, one I2S, and two CANs. Additional peripherals such as trigger selection controller (TRIGSEL), multi-function communication interface (MFCOM), DMA request multiplexer (DMAMUX) are included.

The GD32E502 product series operates from a 2.7 to 5.5 V power supply and is available in a –40 to +125 °C temperature range. Several power-saving modes provide the flexibility for maximum optimization between wakeup latency and power consumption, an especially important consideration in low-power applications.

These features make the GD32E502 product series suitable for a wide range of applications, especially in areas such as industrial control, motor drives, user interfaces, power monitoring and alarm systems, consumer and handheld equipment, gaming and GPS, E-bikes, optical module and more.
