Advance Information
ISO Serial Link Interface
The MC33290 is a serial link bus interface device designed to provide
bi–directional half–duplex communication interfacing in automotive
diagnostic applications. It is designed to interface between the vehicle’s
on–board microcontroller and systems off–board the vehicle via the special
ISO K line. The MC33290 is designed to meet the “Diagnostic Systems
ISO9141” specification. The device’s K line bus driver’s output is fully
protected against bus shorts and over temperature conditions.
The MC33290 derives it’s robustness to temperature and voltage
extremes from being built on a SMARTMOSprocess, incorporating CMOS
logic, bipolar/MOS analog circuitry, and DMOS power FETs. Though the
MC33290 was principally designed for automotive applications, it is suited for
other serial communication applications. It is parametrically specified over an
ambient temperature range of –40°C TA 125°C and 8.0 V VBat 18 V
supply. The economical 8 pin DIP and SO–8 surface mount plastic packages
make the MC33290 very cost effective.
Designed to Operate Over Wide Supply Voltage of 8.0 to 18 V
Ambient Operating Temperature of –40°C to 125°C
Interfaces Directly to Standard CMOS Microprocessors
ISO K Line Pin Protected Against Shorts to Ground
Thermal Shutdown with Hysteresis
Maximum Transmission Speeds in Excess of 50 k Baud
ISO K Line Pin Capable of High Currents
ISO K Line can be Driven with up to 10 nF of Parasitic Capacitance
8.0 kV ESD Protection Attainable with Few Additional Components
Standby Mode: No VBat Current Drain with VDD at 5.0 V
Low Current Drain during Operation with VDD at 5.0 V
