Frequently Asked Questions
What is the maximum clock frequency of AC78013?
The AC78013 features ARM Cortex-M0+ processor running at up to 48MHz. This frequency provides adequate performance for typical body control applications including HVAC control, lighting management, and door module control. The core includes single-cycle multiplier for efficient arithmetic operations. For applications requiring higher processing performance, consider the AC781x series with Cortex-M3 core at 72MHz or AC7840x series with Cortex-M4F at 120MHz.
48MHz is sufficient for most body control applications. Contact LiTong for performance analysis of your specific application.
Does AC78013 support CAN-FD communication?
Yes, the AC78013 includes CAN-FD (Controller Area Network with Flexible Data-rate) interface supporting both classical CAN and CAN-FD protocols. CAN-FD allows higher data rates up to 5 Mbps and larger payload up to 64 bytes per frame, enabling faster communication for modern vehicle networks. The CAN controller includes hardware message filtering and FIFO buffers for efficient message handling. This feature makes AC78013 suitable for integration into modern vehicle communication networks.
AC78013 CAN-FD support makes it ideal for modern automotive networks requiring high-speed communication.
What ADC resolution does AC78013 provide?
The AC78013 includes a 12-bit Successive Approximation Register (SAR) ADC with up to 16 external input channels. The ADC supports single-shot and continuous conversion modes with programmable sampling times. Conversion time is approximately 1 microsecond per sample. The ADC includes internal voltage reference and temperature sensor channel. For applications requiring higher resolution, external ADCs can be interfaced via SPI.
12-bit resolution is sufficient for most automotive sensor applications. Contact LiTong for high-precision measurement requirements.
What development tools are available for AC78013?
AutoChips provides comprehensive development tools for AC78013 including AC7801x SDK with peripheral drivers and example code, support for Keil MDK and IAR Embedded Workbench IDEs, JTAG/SWD debug interface support, and Flash programming tools. The SDK includes AUTOSAR MCAL drivers for automotive applications. AutoChips also provides evaluation boards and reference designs to accelerate development.

Is AC78013 suitable for functional safety applications?
The AC78013 is designed for QM (Quality Managed) applications and does not include specific hardware safety features for ASIL compliance. For applications requiring ASIL-B or ASIL-D functional safety, consider the AC7840x series which includes dual-core lockstep, ECC memory, and comprehensive safety features. AC78013 can be used in safety-related systems when combined with external safety monitoring and appropriate software safety mechanisms.
Use AC78013 for non-safety-critical applications. Contact LiTong for ASIL-compliant MCU recommendations.
