HOW DOES IT WORK?
DIGI Isolator Click is based on two DCL540C01, high-speed, quad-channel digital isolators from Toshiba Semiconductor. Toshiba used the magnetic coupling structure and CMOS technology to achieve high reinforced isolation. The isolated lines are divided into two electrically connected groups. The first group comes in the form of 8 screw terminals, while the second forms a classic male 10-header row for easier jumper wire usage. Both groups of connectors have the same functions and are labeled the same. You can distinguish the power VDD2 and GND2 lines from the data lines: four SPI, UART TX/RX, and two digital IO lines. The isolator can work with supply voltages from 2.25 up to 5.5V.
DIGI Isolator Click uses standard 4-Wire SPI serial interface lines, standard UART TX/RX interface lines, and two additional GP lines from the mikroBUS™ socket as an insulated extension, marked D2 and D1, respectively. The SPI and UART pins are labeled according to the standard interface markings. These eight lines go through the DCL540C01s to the terminals and headers, thus isolating the host MCU from the connected device.
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. This Click board™ is equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
