STMicroelectronics AEK-COM-ISOSPI1 SPI to Isolated SPI Dongle
STMicroelectronics AEK-COM-ISOSPI1 SPI to Isolated SPI Dongle is based on an L9963T transceiver. This dongle converts SPI signals into isolated SPI signals and reduces the number of wires from 4 to 2. The ISOSPI protocol features differential communication to help higher noise immunity and robustness for long-distance communications. The AEK-COM-ISOSPI1 dongle hosts the L9963T transceiver, which can be configured as a slave or master of the SPI bus and supports 8-bit to 64-bit SPI frames. This dongle can be connected via SPI with SPC5, Stellar, and STM32 microcontroller families. The AEK-COM-ISOSPI1 is used in Battery Management Systems (BMS) and isolated communication over SPI protocol.
Features
- Hosts the L993T transceiver
- Master/slave configuration through GPIOs or jumpers
- 4 configurable pins for the SPI protocol
- 2 configurable pins for the amplitude and frequency of the converted signal (ISOSPI)
- 85mm x 30mm dimensions
- Included in the AutoDevKit ecosystem
Applications
- Battery Management System (BMS)
- Isolated communication over SPI protocol
