Microcontrollers Procurement Notes

Verify the specific suffix KU2R against official NXP documentation to confirm the LQFP-176 package type and tape-and-reel shipping configuration. Ensure the order matches the exact part number variant, as suffixes define critical physical and logistical attributes distinct from the base MPC5746C model specifications.

Microcontrollers Selection Notes

Select this component when a 120 MHz operating frequency suffices for the application's computational load, distinguishing it from higher-speed variants like the 160 MHz models. The LQFP-176 package is suitable for designs prioritizing ease of assembly over extreme pin density. Confirm that the integrated 3 MB Flash and 384 kB RAM meet the software footprint requirements without external memory expansion.

Microcontrollers Part Context

This MCU belongs to the MPC574xC family, designed specifically for automotive powertrain and chassis applications. It utilizes the Power Architecture e200z4 core, providing single-precision floating-point operations and variable length encoding for code density. The series emphasizes functional safety compliance and secure boot capabilities essential for modern vehicle electronic control units.

Microcontrollers Replacement Considerations

SPC5746CK1MMJ6R offers identical core specifications but utilizes a MAPBGA-256 package instead of LQFP-176. Verify board layout compatibility before substitution. Other MPC5746C variants may differ in clock speed or interface availability; consult the datasheet for precise electrical and pinout comparisons.
