Maxim provides a recommended PCB layout in the application note AN1911, which includes guidelines for signal routing, power supply decoupling, and thermal management to ensure optimal performance and minimize EMI.
The DS80C310 can use an external clock source or an internal oscillator. For a reliable clocking scheme, use a high-quality external clock source, such as a crystal oscillator, and ensure that the clock signal is properly terminated and decoupled. Additionally, consider using a clock buffer or repeater to ensure signal integrity.
The DS80C310 has a maximum junction temperature of 150°C. To ensure reliable operation, provide adequate heat sinking, such as a thermal pad or heat sink, and ensure good airflow around the device. Additionally, consider using thermal interface materials to improve heat transfer.
To troubleshoot JTAG issues, check the JTAG signal integrity, ensure that the JTAG clock frequency is within the recommended range, and verify that the JTAG pins are properly connected and terminated. Additionally, use a JTAG analyzer or logic analyzer to debug the JTAG signal.
The DS80C310 requires a specific power sequencing to ensure reliable operation. The recommended power sequencing is to power up the VCC supply first, followed by the VDD supply, and then the VPP supply. Ensure that the power supplies are properly decoupled and filtered to minimize noise and transients.
