QFP44 adapter for ET7190 programming which is an Ehanced vehicle network communication protocol controller

This chip (QFP44 package) is full-functional vehicle network communication protocol controller, with built-in enhanced CAN2.0B Active module, J1850 (VPW 10.4KP and PWM 41.6KB) controller, and enhanced EUART controller. These three modules can simultaneously receive and send data at a high speed, which can be applied to vehicle diagnosis, signal control, vehicle gateway, bus data monitoring analysis,etc.

It is the popular device for the Ehanced vehicle network communication protocol controller.

So it have much more programming demand.

The TQFP44 QFP44 programming socket is also required.

ET7190 Support Protocol

1. J1850VPW 10.4kbps
2. J1850PWM 41.6kbps

ET7190 Advantages in comparison with other chips

1. High speed, ET7190 can deal with full load on CAN/J1850/UART bus. Support any application of other industry.
2. EUART/J1850/CAN three modules can simultaneously receive and send data at a high speed。
3. J1850 IFR1/IFR2/IFR3,No-error arbitration transmit and receive, automatic hardware synchronization in transmiting.
4. Enhanced EUART Controller,support any UART-based communication on vehicle.
5. ET7190 is not just a OBD2 diagnostic chip, it's function is unlimited
6. EUART supports 3 channel bus, CAN supports 2 channel bus. Switch via internal electronic switch 
7. EUART Fault Protection。
8. All bus drived by Specail Transceiver . Security, stability, specification .
