A9 Serial Interface
The A9 ECU Interface product is a high-speed ECU interface that efficiently communicates to an ECU over the processor’s DAP interface. To use the A9, a simple plug-and-play gigabit Ethernet interface can be connected directly to a PC or standard LAN, eliminating any need for expensive interface boxes. Hardware IEEE-1588 PTP time synchronization ensures accurate correlation to other acquired data
- Calibrate, DAQ, and Flash ECUs with a single product
- Wide -40 to +105°C operating temperature range
- Automotive surge tolerant wide operating voltage of 5 to 36VDC
- Plug and play direct Ethernet connection to PC
- 1Gbps Ethernet w/IEEE-1588 PTP time sync
- ECU cold start capability for instantaneous data acquisition at ECU power-up
- Dynamic data rates allow real-time reconfiguration of acquired data items
- Support for 125,000 unique data items
- Any DAQ item addressable within the ECU
- DAP interface up to 160MHz with auto-sense speed and multiphase receive
