Microcontrollers Procurement Notes

Verify the specific suffix BK0VLU1 against the official NXP datasheet to confirm the exact memory configuration, clock speed, and temperature grade. Ensure the LQFP-176 package type matches the target PCB footprint requirements. Cross-reference the manufacturing date code and RoHS compliance status with current distributor listings to guarantee component authenticity and regulatory adherence for automotive production lines.

Microcontrollers Selection Notes

Select this model when an 80 MHz performance level with 1.5 MB Flash and 128 kB RAM is sufficient for the application logic. The e200z4d core architecture is suitable for complex control algorithms requiring robust interrupt handling. Consider the 147 available I/Os and extensive peripheral set for system integration needs. Validate that the +125°C maximum operating temperature aligns with the thermal environment of the intended deployment zone.

Microcontrollers Part Context

This component belongs to the MPC564xB family of 32-bit MCUs designed by NXP Semiconductors. The series targets automotive markets with integrated safety features and diverse communication interfaces. It shares architectural similarities with other MPC564x variants but differs in specific memory sizes, clock frequencies, and core configurations such as the single e200z4d core found in this part.

Microcontrollers Replacement Considerations

SPC5644CAVLU1 offers similar specifications but operates at 120 MHz with 192 kB RAM and uses dual cores (e200z0h, e200z4d). Verify pin compatibility and software migration efforts before substitution due to differences in clock speed and memory resources.
