Nrf24l01 Connection?

[azmi42]

Hello,

My sck frequency will be 5Mhz.

Accordingly, nrf24l01 + mcu and SPI parameters as Rpull = 10kohm and Cload = 50pF
How should I connect pins and which pins ( (ce,csn,sck,mosi,miso,irq)) do I need to connect according to the SPI time parameter?

This just show the worst case timing with "heavy" load/impedance on the pins(simulated with 50pF load and 10kohm pull). This is not something you really need to consider if you plan to use 5MHz, just connect the pins as shown in the reference layout to your MCU (do not add the load and pull-up resistor shown in figure 26).

Do you think my nrf is original?

The person I bought says it's original.

Can you please check it?

The marking looks good, but to be sure you would likely need to ship it here for analysis.

Best regards,
