STMicroelectronics provides a recommended PCB layout for the ST62T20B6/HWD in the application note AN4965, which includes guidelines for thermal pad connection, thermal vias, and copper pouring to ensure optimal thermal performance.
The power-up sequence for the ST62T20B6/HWD is critical to ensure proper operation. The recommended power-up sequence is to first apply VCC, then VPP, and finally the clock signal. This sequence is described in the datasheet, but it's essential to follow it carefully to avoid damage to the device.
While the datasheet specifies the recommended operating voltage range for VPP, it's essential to note that the maximum allowed voltage on the VPP pin is 13.2V. Exceeding this voltage can damage the device.
A reliable reset circuit is crucial for the ST62T20B6/HWD. A recommended implementation is to use a resistor-capacitor (RC) network with a diode to ensure a clean reset signal. The application note AN4965 provides a detailed example of a reset circuit implementation.
When designing with the ST62T20B6/HWD, it's essential to consider EMI and EMC. This includes using a solid ground plane, minimizing trace lengths, and using shielding or filtering to reduce electromagnetic radiation. STMicroelectronics provides guidelines for EMI and EMC in the application note AN4965.
