Description

The Intersil HIP7010, J1850 Byte Level Interface Circuit, is a member of the Intersil family of low-cost multiplexed wiring ICs. The integrated functions of the HIP7010 provide the system designer with components key to building a “Class B” multiplexed communications network interface, which fully conforms to the VPW Multiplexed Wiring protocol specified in the SAE J1850 Standard.

Features

? Fully Supports VPW (Variable Pulse Width) Messaging Practices of SAE J1850 Standard for Class B Data Communications Network Interface - 3-Wire, High-Speed, Synchronous, Serial Interface

? Reduces Wiring Overhead

? Directly Interfaces with 68HC05 and 68HC11 Style SPI Ports

? 1MHz, 8-Bit Transfers Between Host and HIP7010 Minimize Host Service Requirements

? Automatically Transmits Properly Framed Messages

? Prepends SOF to First Byte and Appends CRC to Last Byte

? Fail-Safe Design Including, Slow Clock Detection Circuitry, Prevents J1850 Bus Lockup Due to System Errors or Loss of Input Clock

? Automatic Collision Detection

? End of Data (EOD), Break, Idle Bus, and Invalid Symbol (Noise/Illegal Symbols) Detection

? Supports In-Frame Responses with Generation of Normalization Bits (NB) for Type 1, Type 2, and Type 3 Messages

? Wait-For-Idle Mode Reduces Host Overhead During Non-Applicable Messages

? Status Register Flags Provide Information on Current Status of J1850 Bus

? Serial I/O Pins are Active Only During Transfers - Bus Available for Other Devices 95 of the Time

? TEST Pin Provides Built-in-Test Capabilities for In-System Diagnostics and Factory Testing

? High Speed (4X) Receive Mode for Production and Diagnostic Testing/Programming

? Operates with Wide Range of Input Clock Frequencies

? Power-Saving Power-Down Mode

? Full -40oC to +125oC Operating Range

? Single 3.0V to 6.0V Supply
