ATA6847T-3333E/NHX

Overview

The ATA6847T-3333E/NHX is a high-performance automotive transceiver IC designed for robust communication in demanding environments. It integrates a CAN FD controller, a LIN controller, and a high-speed CAN transceiver with integrated ESD protection. The device supports flexible baud rates up to 5 Mbit/s for CAN FD and 20 kbit/s for LIN. It features a 32-bit ARM Cortex-M0 core for local processing and protocol handling. The IC includes extensive diagnostic capabilities, including bus fault detection and thermal shutdown. It operates within an extended temperature range of -40°C to +125°C and is housed in a compact HTSSOP-48 package.

• Provides comprehensive hardware-based diagnostics and error handling mechanisms
• Features integrated electrostatic discharge (ESD) protection on communication lines

Applications

• Automotive body control modules
• Gateway units for vehicle network integration
• Door control electronics
• Seat adjustment systems

Procurement Notes

Verify the specific suffix 'NHX' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with required operating voltage levels and interface protocols before procurement. Cross-reference the component revision level to guarantee silicon errata compliance for your specific design implementation.

Selection Notes

Select this component when simultaneous CAN FD and LIN connectivity is required within a single package. It is suitable for applications needing local processing power via the embedded MCU to reduce host CPU load. Consider its diagnostic features for safety-critical systems requiring detailed fault reporting. Evaluate the pin count and package size against available PCB real estate constraints.

Part Context

This part belongs to Microchip's ATA68xx family of automotive transceivers. These devices are engineered to simplify complex vehicle network architectures by combining multiple communication interfaces into one chip. The family targets the growing demand for efficient, diagnostic-rich nodes in modern automotive electronic control units.

Replacement Considerations

Check for direct pin-to-pin replacements within the same ATA68xx series that may offer updated firmware support or different packaging options. Verify functional equivalence regarding CAN FD timing parameters and LIN synchronization capabilities before substitution.
