描述 Description

The NXP? MC33793 is designed to be used with a sensor or actuator at a location that is remote from a centralized MCU.
Provides power, measurement, local logic I/O and communications between the remote sensor and the centralized MCU over a DSI bus
Sensors can be powered from the regulated output of the device and the resulting analog value can be converted from an analog level to a digital value for transmission over the DSI bus in response to a query from the MCU
Four I/O lines can be configured by the central MCU over the DSI bus
Replaces MCU and supporting hardware in remote measurement and control applications, resulting in a significant cost reduction

特性 Features

? Four channel 8 bit A-to-D converter
? Four pins configurable as analog or logic inputs or as logic outputs
? Provides regulated +5.0 V output for sensor power from bus
? Additional high-drive logic output
? On-board clock (no external elements required)
? Field programmable address
? Default and field programmable as a DSI daisy chain device
? Recognizes reverse initialization for open bus fault tolerance
