I am designing a board based on the Atmega328P microcontroller. For this controller there is an ISP connector for programming. This connector has the following pins: MOSI / MISO / RST / SCK.
There is a task to protect this tire from electrostatic discharges.
To protect IO / I2C / UART, I use NUP4114.
It is designed to protect several IOs simultaneously.
Question: Is this circuit suitable for ISP / SPI line?
