Description
The STEVAL-BMS1T is a SPI to isolated SPI dongle, which allows converting SPI signals into isolated SPI signals, thus reducing the number of necessary wires from 4 to 2.The ISOSPI protocol features differential communication to ensure higher noise immunity and robustness for long-distance communications.The STEVAL-BMS1T is based on the L99BM1T general-purpose SPI to isolated SPI bidirectional transceiver, which can transfer communication data incoming from a classical 4-wire based SPI interface to a 2-wire isolated interface (and vice versa).The L99BM1T hosted on the STEVAL-BMS1T can be configured either as a slave or as a master of the SPI bus and supports any protocol of 8-to-64-bit SPI frames.The SPI peripheral can work up to 10 MHz when configured as a slave. The SPI clock frequency can be programmed (250 kHz, 1 MHz, 4 MHz, or 8 MHz) when the device is configured as a master.The transceiver is natively compatible with the L99BM114 isolated SPI, allowing its usage in battery management system (BMS) applications. The basic BMS analog front-end node board is the STEVAL-BMS114.From the microcontroller side, the STEVAL-BMS1T board can be connected via SPI with SPI enabled microcontrollers and in particular with STM32 microcontroller families.
Features
Hosts the L99BM1T general purpose SPI to isolated SPI bi-directional transceiverMaster/slave configuration through GPIOs or jumpers4 configurable pins for the SPI protocol2 configurable pins for amplitude and frequency of the converted signal (ISOSPI)Dimensions: 85mm x 30mm
Typical applications
- Energy generation and distribution
