Overview
The GD32E502 product series incorporates an Arm® Cortex®-M33 32-bit processor core operating at up to 100 MHz. It provides up to 384 KB Flash and 48 KB SRAM. A wide range of enhanced I/Os and peripherals are connected to two APB buses.
The series features two 12-bit ADCs, one DAC, one comparator, one general-purpose 16-bit timer, two basic timers, and four advanced PWM timers. It also supports a comprehensive set of communication interfaces, including up to two SPIs, two I2Cs, three USARTs, one I2S, and two CANs. Additional peripherals such as the Trigger Selection Controller (TRIGSEL), Multi-Function Communication Interface (MFCOM), and DMA Request Multiplexer (DMAMUX) further enhance system flexibility.
The GD32E502 product series operates from a 2.7 V to 5.5 V power supply and –40 °C to +125 °C temperature range. Multiple power-saving modes provide flexibility to optimize the trade-off between wakeup latency and power consumption, making the series well suited for low-power applications.
These features make the GD32E502 product series suitable for a wide range of applications, including industrial control, motor drives, user interfaces, power monitoring, alarm systems, consumer and handheld devices, GPS equipment, e-bikes, optical modules, and more.
