My customers are testing ESD on their board using MSP430F6726A. We have seen the following document.
■MSP430 System ESD Troubleshooting Guide
3.3 Hardware Troubleshooting Guidelines
Figure 2. Recommended SBW Circuit for MSP430 MCUs
Since MSP430 resets during ESD testing, they want to change the pull-up resistor value of the reset pin to 4.7kΩ. They thought the increased current would make it more robust to noise.
Is it okay?
