HOW DOES IT WORK?
SPI Isolator 5 Click is based on the DCL541A01, a high-speed quad-channel digital isolator from Toshiba Semiconductor. The DCL541A01 stands out with its exceptional performance capabilities, made possible by leveraging Toshiba's advanced CMOS technology and a magnetic coupling structure. Not only does it meet the stringent safety standards of UL 1577 certification, but it also boasts an impressive withstand voltage rating of 5kVrms. Furthermore, its operating range spans from 2.25V to 5.5V, enabling seamless integration with lower voltage systems and facilitating voltage translation functionality across isolation barriers. With its versatility, this Click board™ is well-suited for various applications, including industrial automation systems, motor control, inverters, and more.
SPI Isolator 5 Click communicates with an MCU using the SPI serial interface with a maximum data rate of 150Mbps. The isolated lines are divided into two groups with the same lines. The first group comes in the form of 5 screw terminals, while the second forms a classic male 5-header row for easier jumper wire usage. Both groups of connectors have the same functions. You can distinguish the power VDD2 and GND2 lines from the data lines, which are CS2, SCK2, SDI2, SDO2, and DIS2. The DIS and DIS2 pins have the same function: to disable the lines from the side of the isolator on which they are located. By setting the DIS pin to a high logic level, the input signals are disabled, and by setting it to a low logic level, they are enabled. The isolator can work with external supply voltages from 2.25V up to 5.5V, and the existence of an external power supply is easily visible using the PWR2 LED indicator.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL switch. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
