产品概述
描述
L99BM1T is a general purpose SPI to isolated SPI transceiver intended to create a communication bridge between devices located into different voltage domains.
L99BM1T is able to transfer communication data incoming from a classical 4-wire based SPI interface to a 2-wire isolated interface (and viceversa).
The transceiver supports both transformer and capacitive isolation.
The device can be configured either as Slave or as Master of the SPI bus and supports any protocol made of SPI frames 8 to 64 bit long.
SPI peripheral can work up to 10 MHz when configured as Slave. SPI clock frequency can be programmed among (250 kHz; 1 MHz; 4 MHz; 8 MHz) when configured as Master.
Isolated SPI peripheral features two different operating modes: slow @333 kbps and fast @2.66 Mbps.
The asynchronicity between the two sides is internally managed, allowing all possible configuration frequencies on both peripherals to be used in application.
The device is natively compatible with L99BM114 isolated SPI, allowing its usage in the BMS applications.
L99BM1T is compatible with both 3.3 V and 5 V logics.
