FAQ

What is the maximum operating frequency of the SPC5604BK0MLH6R?

The SPC5604BK0MLH6R operates at a maximum frequency of 64 MHz, achieved through its Frequency-Modulated Phase-Locked Loop (FMPLL). This speed is validated across the full industrial temperature range (−40°C to 125°C) and supports deterministic real-time execution for automotive body control tasks. The e200z0h core maintains consistent performance due to its single-issue pipeline and VLE-optimized instruction fetch.

Does the SPC5604BK0MLH6R support AUTOSAR-compliant timing services?

Yes, the SPC5604BK0MLH6R supports AUTOSAR timing services via its System Timer Module (STM) and six Periodic Interrupt Timers (PIT) with 32-bit resolution. These peripherals provide precise, jitter-free timing events required for OS tick generation, schedule table management, and time-triggered communication - all accessible through standardized AUTOSAR MCAL drivers provided by NXP.

How many CAN interfaces does the SPC5604BK0MLH6R integrate, and what protocol versions are supported?

The SPC5604BK0MLH6R integrates six independent FlexCAN modules, each supporting CAN 2.0A/B protocol with configurable message buffers and flexible acceptance filtering. All six modules operate concurrently and support bit rates up to 1 Mbps, enabling multi-domain vehicle networking such as separate CAN buses for door, seat, and lighting subsystems without external CAN controllers.

What debug interface does the SPC5604BK0MLH6R provide, and is it production-ready?

The SPC5604BK0MLH6R features a Nexus 2+ development interface compliant with IEEE-ISTO 5001-2003 Class Two Plus, supporting real-time trace, complex breakpoints, and memory watchpoints. This interface remains fully functional in production firmware and is used for both development and field diagnostics - no hardware disablement is required for release builds.

Is the SPC5604BK0MLH6R pin-compatible with other members of the MPC5604B/C family?

Yes, the SPC5604BK0MLH6R shares identical pinout and electrical characteristics with other MPC5604B/C variants in the 144-pin LQFP package, including MPC5604BK0MLH6 and MPC5604CK0MLH6R. Differences are limited to flash configuration, peripheral enablement, and qualification grade - allowing shared PCB designs across functional variants in the same package footprint.
