The 33SA0528 is a third generation SMARTMOS standalone, dual-channel distributed system interface (DSI) master device.

Each of the two independent channels contain a differential driver and a dual adder receiver. The embedded DSI protocol engine converts the DSI data between the physical interface and the two redundant SPI interfaces. The MCU can control and configure the 33SA0528 and extract all of the slaves transceivers data from it via the dual SPI.

To ensure the communication reliability, the 33SA0528 uses an on-chip band gap reference regulator to monitor all of the supply voltages, and uses an on-chip oscillator to monitor the PLL clock for the external clock error detection.

Features

•Two independent DSI master channels

•Supports command and response mode for slave configuration

•Supports periodic data collection mode (PDCM) for periodic slave data transfers

•Supports discovery mode for slave physical address self-programming

•10 MHz 32-bit dual SPI: main SPI for device configuration and DSI operation, and redundant SPI for safety purposes

•Point-to-point, parallel, daisy chain bus topologies

•Various diagnostic features

Applications

•Automotive airbag and safety

•Industrial systems

•Sense and trigger applications
