你好。我在制作一个核辐射设备。
我想问一下,一个脉冲可以唤醒DSP的最短时间是多少,是哪种型号?
我看见5系列唤醒的时间为33.5us。

其他,如C5501,以3.33-ns Instruction Cycle Time for300-MHz Clock Rate的速率来算,时间都要比上面长。
To take the 5501 (including the internal oscillator) out of the idle 3 state, execute the following procedure:
1. External interrupt or NMI occurs (as specified in the WKEN register) and program flow begins after
41,032 reference clock cycles.
2. CPU wakes up.
