Internal Weak Pull-Up and Weak Pull-Down Resistor Table 11. Internal Weak Pull-Up and Weak Pull-Down Resistor Values for Cyclone 10 DevicesAll I/O pins have an option to enable weak pull-up except the configuration, test, and JTAG pins. The weak pull-down feature is only available for ...
weak pull up和weak pull down是什么意思啊? 一个输入引脚,想在库里找一个合适的pad,发现了一种PIC pad和PICD pad,PICD pad好象就是多加了一个NMOS管,具有weak pull down功能,可以在输入为RL(resistive low)时让输出为0,我有点不太清楚。 RL是什么意思呢,这样的一个weak pull down具体有什么功能呢?

I'd like to add weak pull-down resistors for used input I/O pins on cyclone V. However, I can only find an optional programmable pull-up resistor for each I/O pin in handbook. Is there any way to add a weak pull-down resistor for used input I/O pi...

Part Number: DP83848K Would you let me know the range of resistance values for the weak internal pull-down of PHYAD1 to PHYAD4? If there is no nominal value,
There are weak pull-down for REF input and all outputs of Cypress clock buffers that can be checked in respective datasheets. One do not need to
- Weak pull-up with weak pull-down (Q1)Could you tell us about the "Resistance value" for each of the above weak pull-up and strong pull-up? Regarding the following description "3 Pinouts" on Page8 of the CCG3PA Data-Sheet.
pullup、pulldown看做是门级原语,assign语句看做是RTL。 SystemVerilog接口不允许门级原语。如果是用来写ip,应该使用assign语句。 一些工具,像静态时序分析,期望用门级原语建模,而不是RTL,这时应该使用pullup、pulldown来代替。 pullup、pulldown默认的驱动强度是pull,assign语句默认的驱动强度是strong。
