Altera FPGA IO口驱动电流的理解
请高手指点:Altera FPGA Cyclone II Devices Handbook 第314页,即图片内容疑问:
(1)per power pair :是指芯片每个VCCI 还是芯片总电源?
(2)There is a current limit of 240 mA per 12 consecutive output side (left and right) pins per power pair;left and right是指PQFP封装芯片的意思吗?
There is a current limit of 240 mA per eight consecutive output top and bottom pins per power pair;top and bottom是指BGA封装芯片的意思吗?
其次连续最大输出电流240mA是FPGA芯片所有IO口最大同时能输出这么大电流还是针对一个VCCI来的电流?
