Frequently Asked Questions
What is the difference between AC78013 and AC78014?
The AC78014 is an enhanced version of AC78013 with double the Flash memory (256KB vs 128KB) and RAM (32KB vs 16KB). It also adds a second CAN-FD interface for gateway applications and includes a hardware security module. The AC78014 is ideal for more complex applications requiring additional memory, dual CAN networks, or security features. Both devices share the same Cortex-M0+ core and peripheral architecture, enabling easy software migration.
Select AC78014 for gateway applications or when additional memory is needed. Use AC78013 for cost-sensitive single-network applications.
What is the purpose of the hardware security module (HSM)?
The hardware security module provides cryptographic acceleration and secure key storage for automotive security applications. It supports secure boot, firmware authentication, and encrypted communication. The HSM protects against unauthorized firmware updates and ensures system integrity. This is essential for modern automotive ECUs that require cybersecurity compliance.
Use HSM features for applications requiring secure boot or firmware protection.
Can AC78014 operate in gateway applications?
Yes, the AC78014 is specifically designed for gateway applications with its dual CAN-FD interfaces. The two independent CAN controllers can operate on separate networks with different baud rates. The 256KB Flash provides space for protocol conversion software. The Cortex-M0+ core handles routing between networks efficiently. Gateway applications benefit from the hardware security features for secure communication.
AC78014 is ideal for gateway applications connecting multiple vehicle networks.
What development tools are supported for AC78014?
The AC78014 supports industry-standard ARM development tools including Keil MDK, IAR Embedded Workbench, and GCC-based toolchains. AutoChips provides device-specific drivers, example code, and application notes. The MCAL drivers support AUTOSAR integration. Debug support includes JTAG and SWD interfaces compatible with popular debuggers.
Use familiar ARM toolchain. AutoChips provides comprehensive software support.
What is the ECC protection and why is it important?
Error Correction Code (ECC) protection detects and corrects single-bit errors in Flash and RAM. This is critical for automotive safety applications where data integrity is essential. The ECC hardware automatically corrects errors without software intervention. This improves system reliability and helps meet functional safety requirements.
ECC protection is essential for safety-critical automotive applications.
