As being the industries highest-performance Cortex®-M4 microcontroller, the GD32F450 delivers ultra-high computing performance, with a maximum processor clock speed of 200MHz, and provides a complete DSP instruction set, parallel computing power, and dedicated floating- FPU to meet advanced computing requirements. At the maximum frequency the performance of the GD32F450 is up to 250 DMIPS, and in the CoreMark® test he has achieved with 673 points an outstanding performance. The Cortex®-M4 is 10% -20% more efficient than the Cortex®-M3 and offers over 40% performance improvement over the Cortex®-M3.
GD32F450 is equipped with 512KB to 3072KB of on-chip flash and 256KB to 512KB of SRAM, dual-block (dual-bank) flash memory allows synchronous read and write operations, thus facilitating the security program upgrades, updating software without affecting application performance. Using industry-leading low-power 55nm manufacturing process the GD32 series MCU continues the high level of integration features and to ensure product price control. GD32F450 is using 2.6V-3.6V power supply, and the I/O port can withstand 5V.
The built-in power management unit supports advanced power management and provides three power-saving modes, operating at 500μA / MHz at full peripheral speed in all peripherals for excellent energy efficiency. But also for the first time with the voltage adjustment function. When the frequency decreases, CPU voltage can also be reduced, what will minimize the dynamic power consumption level. The standby current is as low as 2μA so that the device can be used also for battery application.
