兆易创新GD32 ARM Cortex-M33微控制器GD32 ARM Cortex-M33 Microcontrollers
The GD32E5 series is based on the Arm® Cortex®-M33 core from the latest Armv8-M architecture. System frequency supports up to 180MHz, includes a built-in hardware multiplier/divider, DSP instruction set and single-precision floating-point unit (FPU).
GD32E50x系列器件是基于Arm® Cortex®-M33处理器的32位通用微控制器。Cortex®-M33处理器基于Armv8架构,处理器主频高可达180MHz,支持强大的可扩展指令集,包括通用数据处理I/O控制任务、增强的数据处理位域操作、DSP和浮点运算器(FPU).
It is also equipped with a new hardware trigonometric math unit (TMU) that supports vector, sine and cosine, exponent, square root, common logarithm and other mathematical trigonometric operations, reducing the burden on the CPU and improving the processing efficiency. Additionally, it has a built-in memory protection unit (MPU) for task isolation, improving system’s reliability.
GD32E5还配备了全新的硬件三角函数加速器(TMU),可支持矢量、正余弦、指数、平方根、常用对数等数学三角运算,以减轻CPU负担并提高处理效率,还内置了用于任务隔离的内存保护单元(MPU)用于提高系统可靠性。
The devices operate from a 1.7V to 3.6 V power supply, the I/O port can support 5V voltage levels and are available in –40°C to +85°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.
