10.7. Intel® Cyclone® 10 GX器件的上电排序考量

The Intel® Cyclone® 10 GX devices require a specific power-up and power-down sequence. This document describes several power management options and discusses proper I/O management during device power-up and power-down. Design your power supply solution to properly control the complete power sequence.

The requirements in this document must be followed to prevent unnecessary current draw to the FPGA device. Intel® Cyclone® 10 GX devices do not support 'Hot-Socketing' except under the conditions stated in the table below. The tables below also show what the unpowered pins can tolerate during power-up and power-down sequences.

表 96.  Pin Tolerance – Power-Up/Power-Down'√' is Acceptable; '-' is Not Applicable.
  Power-Up Power-Down
Pin Type 三态 Drive to GND Drive to VCCIO Driven with < 1.1 Vp-p 三态 Drive to GND Drive to VCCIO Driven with < 1.1 Vp-p
3VIO banks - - - - -
LVDS I/O banks 31 - 31 -
Differential Transceiver pins - -
31 器件未上电或上电/掉电条件= 10 mA时,允许通过任意LVDS I/O bank管脚的最大电流(请参阅“未上电FPGA管脚的LVDS I/O管脚指导”)。
