Microcontrollers in the GD32F5 series from GigaDevice are equipped with 7.5 Mbytes of on-chip flash and 1 Mbyte of SRAM, both supporting ECC verification. Up to 2 Mbytes of code flash can be configured for zero-wait-state operation, improving processing speed and efficiency. A maximum of 2 Mbytes of memory is also available for read-while-write OTA updating. Additionally, the MCUs accommodate a variety of external memories.
The GD32F5 series of MCUs is based on an Arm Cortex-M33 processor. This 32-bit core operates at up to 200 MHz and delivers a performance rating of 3.31 CoreMark/MHz. An integrated 12-bit successive approximation ADC module can sample analog signals from 16 external channels and 2 internal channels, plus the battery voltage channel. MCUs also feature two DACs and multiple timers. Connectivity resources include UART/USART, I2C, SPI, I2S, SDIO, USB, CAN-FD, and Ethernet.
A set of built-in system security features offers protection for both firmware and device private data, as well as service execution assurance. The general-purpose MCUs operate with a supply voltage of 1.71 V to 3.6 V and have 5-V tolerant I/Os. The lineup comprises 10 variants in a choice of packages, including BGA and LQFP.
