3.1 Clock sources
Three different clock sources can be used to drive the system clock (SYSCLK):
(1) HSI oscillator clock
(2) HSE oscillator clock
(3) PLL clock
(4) Interconnect global clocks(FPGA Core)
The devices have the following two secondary clock sources:
(1) 40 kHz low speed internal RC (LSI), which drives the independent watchdog and optionally the RTC used for Auto-wakeup from Stop/Standby mode.
(2) 32.768 kHz low speed external crystal (LSE crystal), which optionally drives the real-time clock (RTCCLK)
Each clock source can be switched on or off independently when it is not used, to optimize power consumption.

核心Features:
内置2K CPLD逻辑单元,可当纯CPLD用,2K Luts;
如当纯MCU用,就跟ST完全 Pin to Pin;
性价比高;
工业级温度范围;
300M主频(实测);
外设跟封装无关,即便是48Pin或者32Pin,也可以通过CPLD配置。这是目前为止同类厂商(含外资厂商)不具备的。
