FAQ

What is the maximum operating frequency of the SPC5604BK0VLQ6R?

The SPC5604BK0VLQ6R operates at a maximum frequency of 64 MHz, achieved via its integrated Frequency-Modulated Phase-Locked Loop (FMPLL). This clock speed supports deterministic real-time execution of AUTOSAR-based software stacks and meets timing requirements for CAN 2.0B and LIN 2.x communication protocols in automotive body electronics applications. The FMPLL also supports spread-spectrum modulation to reduce electromagnetic interference.

Does the SPC5604BK0VLQ6R support functional safety standards like ISO 26262?

Yes, the SPC5604BK0VLQ6R is designed for ASIL-B compliance per ISO 26262. It includes hardware safety mechanisms such as ECC on flash and SRAM, a memory protection unit (MPU) with 8 region descriptors, lockstep-capable peripherals (e.g., FlexCAN CRC checking), and built-in self-test (BIST) support via the ECSM module. These features enable safe partitioning of software components and detection of memory corruption-key requirements for automotive body control applications.

How many CAN interfaces does the SPC5604BK0VLQ6R support, and what protocol versions are compatible?

The SPC5604BK0VLQ6R supports up to six FlexCAN modules, each compliant with the CAN 2.0B specification and capable of bit rates up to 1 Mbps. While not natively supporting CAN FD, its flexible message buffer architecture and programmable timing registers allow implementation of CAN FD-compatible physical layer interfaces when paired with external CAN FD transceivers. All six modules support automatic retransmission, error confinement, and hardware filtering-essential for multi-node automotive networks.

What debug interface does the SPC5604BK0VLQ6R provide, and is it production-ready?

The SPC5604BK0VLQ6R integrates a Nexus 2+ development interface compliant with IEEE-ISTO 5001-2003 Class Two Plus, supporting real-time trace, non-intrusive debugging, and run-control features. It uses dedicated MDO0–MDO3, MCKO, and EVTO pins and remains fully functional in production firmware-enabling field diagnostics, calibration updates, and failure analysis without requiring additional debug hardware or pin multiplexing compromises.

Is the SPC5604BK0VLQ6R pin-compatible with other members of the SPC560x family?

No, the SPC5604BK0VLQ6R is not pin-compatible with other SPC560x variants due to differences in package type and pin assignment. It uses a 144-pin LQFP (20 × 20 mm), whereas alternatives like SPC5604PK0MLL6R use 100-pin LQFP and SPC5602BK0MLH6R use 64-pin LQFP. Pin mappings for peripherals, power, and debug signals differ across packages-even within the same family-requiring unique PCB layouts for each variant.
