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.
The device has a thermal pad on the bottom, which should be connected to a heat sink or a thermal plane on the PCB. Ensure good thermal conductivity and follow the recommended thermal design guidelines to prevent overheating.
The maximum clock frequency is 70 MHz, but it's recommended to operate at a frequency below 60 MHz to ensure reliable operation and minimize power consumption.
To configure the device for low-power operation, use the Power-Down Mode (PD) and Idle Mode (IDLE) features. These modes can be controlled through the device's control registers and can significantly reduce power consumption.
Follow the recommended layout and routing guidelines in the datasheet, including keeping the clock signal traces short and away from noisy signals, and using a solid ground plane to reduce noise and EMI.
