A9 SERIAL INTERFACE
High-speed serial debug port interface for ECU calibration, data acquisition and flashing
The A9 Serial Interface is ATI’s next-generation high-speed ECU interface designed for demanding calibration, rapid prototyping, flashing, and data acquisition applications. By communicating directly through the ECU processor’s DAP interface, the A9 delivers dramatically higher throughput than traditional CAN or CAN FD based acquisition methods while minimizing ECU processor overhead.
Built for automotive development environments, the A9 combines high-speed ECU access, Gigabit Ethernet connectivity, IEEE-1588 PTP synchronization, and dynamic acquisition capabilities into a compact plug-and-play platform.

Modern ECU development programs demand more data, faster acquisition rates, and lower processor impact than traditional CAN-based interfaces can provide.
The A9 Serial Interface addresses these challenges by communicating directly with the ECU processor through the DAP interface. This architecture enables significantly faster acquisition and calibration performance while reducing communication overhead on vehicle networks.
Unlike conventional interfaces that rely on CAN bandwidth limitations, the A9 provides direct high-speed memory access to support demanding calibration and validation workflows, including transient calibration, debugging, rapid prototyping, and synchronized data acquisition.
The result is faster development cycles, improved data visibility, and more efficient ECU validation.
Why A9
Acquire More Data at Higher Speeds
The A9 supports up to 125,000 unique data items and communicates directly with ECU memory through the processor debug interface. Engineers can access more signals at faster rates than CAN or CAN FD based acquisition approaches.
Reduce ECU Processor Impact
By using the processor debug interface rather than communication buses for acquisition, the A9 reduces processor overhead while leaving CAN bandwidth available for diagnostics and additional vehicle communication tasks.
Simplify Calibration & Flashing
The A9 combines ECU calibration, high-speed DAQ, and flash programming into a single platform. Intelligent flashing algorithms help reduce programming time while protecting ECU memory regions.
Enable Accurate Time Correlation
Integrated IEEE-1588 PTP synchronization allows precise correlation between ECU data and additional acquired measurements throughout the vehicle or test environment.
Improve Development Efficiency
Dynamic data rates and real-time reconfiguration reduce setup time and allow engineers to adapt acquisition strategies during testing without rebuilding configurations.
Support Demanding Automotive Environments
Designed for automotive applications, the A9 supports a wide 5 to 36 VDC operating range and −40°C to +105°C operating temperatures.
Accelerate ECU Development
The A9 streamlines the entire ECU development process by combining calibration, high-speed data acquisition, and flash programming into a single, high-performance interface. By communicating directly with the ECU processor through the DAP interface, engineers can move quickly between development tasks without changing hardware or interrupting their workflow.
Real-Time Calibration
Adjust ECU parameters in real time while communicating directly with processor memory. Direct DAP access provides higher throughput than traditional CAN-based interfaces, allowing engineers to work more efficiently during calibration and validation.
High-Speed Data Acquisition
Acquire up to 125,000 unique data items directly from ECU memory using dynamic acquisition rates that can be adjusted as testing evolves. This provides the flexibility needed for transient calibration, diagnostics, and complex development programs while reducing processor overhead.
Intelligent Flash Programming
Program updated ECU software using optimized flashing algorithms designed to reduce programming time during repeated development cycles. Features such as reserved memory protection, enhanced checksum handling, and brain-dead flashing help improve reliability while safeguarding ECU memory.
Direct Processor Access
The A9 communicates directly with the ECU processor through the DAP interface, providing significantly higher throughput than traditional CAN-based interfaces while reducing processor overhead. With support for DAP speeds up to 160 MHz, engineers can access ECU memory quickly for demanding calibration, measurement, and validation tasks.
Precision Time Synchronization
Integrated IEEE-1588 Precision Time Protocol (PTP) hardware synchronization keeps ECU measurements accurately aligned with other synchronized devices. Accurate timestamps simplify correlation between ECU data and external instrumentation, improving confidence during vehicle, laboratory, and test cell testing.
Dynamic Overlay Support
Gigabit Ethernet Connectivity
Native Integration with ATI VISION
The A9 is designed to work seamlessly with ATI VISION Calibration and Data Acquisition Software, creating a streamlined workflow from ECU connection through calibration, measurement, and flashing. Once connected over Gigabit Ethernet, engineers can configure the interface, access ECU memory, acquire high-speed measurements, calibrate parameters, and program new software without switching between multiple tools.
By combining the A9's direct processor access with VISION's calibration and measurement environment, engineers can spend less time configuring hardware and more time developing, validating, and optimizing ECU performance.
Typical Workflow
1. Connect
Connect the A9 to the ECU through the processor's DAP interface and to the development PC using a standard Gigabit Ethernet connection.
2. Configure
VISION automatically communicates with the A9, allowing engineers to configure the interface, establish ECU communication, and prepare calibration and acquisition settings.
3. Calibrate & Acquire Data
Perform real-time ECU calibration while simultaneously collecting high-speed measurement data directly from ECU memory. Dynamic acquisition rates and direct processor access provide the performance needed for demanding development and validation programs.
4. Flash & Validate
Program updated ECU software using the A9's intelligent flashing capabilities, then immediately verify changes through synchronized measurements and additional calibration without changing hardware or interrupting the workflow.
