4.2 MCU Selection and Requirements for Integration Architecture

This integration method is diverse. The charging inlet control system can be integrated in the OBC combo in physics. Deeper integration is achieved by using the same MCU with the DCDC and host subsystems. This form of integration is highly customized and seen in the global market where the charging standard is relatively simple and there are fewer functional safety requirements (especially prevalent in the Chinese market). In these instances, achieving integration is easier.

The resources required for the MCU are increasing. The MCU requires a higher number of ADC channels to sense multiple high-voltage and low-voltage signals for safety monitoring and DCDC control. The DCDC and host subsystems require redundant sensing, lock-step cores, and communication interfaces with end-to-end safing to meet the functional safety standard requirements for ASIL B through ASIL D. Additionally, the MCU requires higher computing power to meet the increased demand for DCDC high-frequency control resulting from increases of system power density.

The F29x series of C2000™ MCUs are an excellent choice for meeting the sufficient sensing resources and high-level functional safety requirements by providing:

  • High-performance real-time control with the latest C29 core running at 200MHz. The C29 core currently delivers real-time performance (in cycles) that is four times faster than the Arm® Cortex®-M7 CPU with 480MHz frequency.
  • The lockstep CPU core offers hardware-automated thread isolation and comprehensive memory protection to help meet functional safety standard requirements.
  • Three 12b ADC converters and two 16b ADC converters with safety redundancy support, up to 80 channels.
  • Systematic and random hardware capabilities that achieve the ISO 26262 standard of requirements up to ASIL D.
  • Evita-full HSM with hardware accelerators to help meet the automotive security requirements of ISO 21434.

For systems with high integration and functional safety requirements, the AM263P and AM263P-SIP are options with increased memory, up to 8MB of flash memory.
