DS89C450-ENG+ Frequently Asked Questions (FAQ)
-
The recommended power-up sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures proper initialization and prevents latch-up or damage to the device.
-
When using the DS89C450-ENG+ in a system with multiple clock domains, it's essential to ensure that the clock signal is properly synchronized and buffered to prevent clock domain crossing issues. Use a clock buffer or a clock domain crossing circuit to synchronize the clock signal.
-
The maximum allowed capacitance on the VCC and VDD pins is 10nF. Exceeding this value can cause power supply noise and affect the device's performance.
-
A reliable reset circuit can be implemented using a voltage supervisor IC, such as the ADM691, which provides a reset signal to the DS89C450-ENG+ during power-up or brownout conditions.
-
To minimize EMI and noise, it's recommended to follow a star-topology layout, keep the clock signal traces short and away from analog signals, and use a solid ground plane. Additionally, use a low-ESR capacitor for power supply decoupling and place it close to the device.
