Safety Bus Interface Chips from Freescale


Freescale Semiconductor
September 10, 2008

The MC33781 master interface device and MC33784 slave interface from Freescale Semiconductor, Austin, TX, are designed for airbag safety systems that use the Distributed Systems Interface (DSI) standard to connect remotely placed sensors to the main airbag electronic control unit. The MC33781 features 4 independent differential DSI channels with a pseudo bus switch on channel 0, 200 Kbps full duplex per channel, dual SPI, enhanced bus fault performance, an enhanced register set with addressable buffer, 8- to 16-bit messages with 0–8 bits of CRC, and independent frequency spreading for each channel. The MC33784 satellite sensor slave interface features a 2-channel 10-bit ADC, 3 pins configurable as logic inputs or outputs, a regulated 5 V output, single-ended or differential receiver, high- and low-side bus switches for improved common-mode noise rejection, 10 MHz internal clock with dithering, DSI daisy chain device, and under-voltage detection.
