Substitute Part Grouping Explanation

Substitution eligibility for the SPC5644AF0MLU1R is determined by strict alignment of the following critical parameters:

• Core Processor Architecture: e200z4 processor required for instruction set compatibility
• Memory Configuration: 4MB FLASH and 192KB RAM minimum specifications
• Package Form Factor: 176-LQFP (24x24) surface mount package for PCB layout compatibility
• Core Clock Speed: 150MHz operational frequency
• Connectivity Interfaces: CANbus, EBI/EMI, LINbus, SCI, and SPI support
• Temperature Range: -40°C to 125°C operating specification
• Compliance Standards: RoHS3 compliance and automotive-grade qualification

The SPC564A80L7CFAR qualifies as a direct substitute based on matching all core electrical and mechanical parameters within the allowed tolerance specifications for this microcontroller category.

Parameter Comparison

Engineering Selection Recommendations

Both the SPC5644AF0MLU1R and SPC564A80L7CFAR maintain Active product status with full RoHS3 compliance and identical moisture sensitivity specifications. The SPC564A80L7CFAR carries automotive-grade qualification with AEC-Q100 certification, providing additional assurance for safety-critical applications. Selection between these parts should be based on supply availability, lead time requirements, and specific application voltage supply constraints. The SPC564A80L7CFAR operates within a narrower supply voltage range (1.14V ~ 1.32V) compared to the main part (1.14V ~ 5.25V), requiring verification of system power delivery specifications before substitution.

Frequently Asked Questions (FAQ)

Q: Are these parts pin-compatible? A: Both parts use the 176-LQFP (24x24) package with identical pin count and layout. Physical PCB compatibility is confirmed.

Q: What are the differences in I/O count? A: The SPC564A80L7CFAR provides 118 I/O pins compared to 84 on the SPC5644AF0MLU1R. This represents additional available I/O resources on the substitute part.

Q: Can the SPC564A80L7CFAR replace the SPC5644AF0MLU1R in existing designs? A: Substitution is feasible for applications operating within the 1.14V ~ 1.32V supply voltage range. Designs requiring the full 1.14V ~ 5.25V range of the main part require voltage supply redesign.

Q: What is the difference in analog-to-digital converter specifications? A: The main part includes 40 channels of 12-bit ADC, while the substitute provides 34 channels of 12-bit ADC. Application requirements for analog input channels must be verified.

Q: Are both parts suitable for automotive applications? A: The SPC564A80L7CFAR carries explicit AEC-Q100 automotive qualification. The SPC5644AF0MLU1R maintains Active status and RoHS3 compliance suitable for industrial applications.

Q: What is the packaging format for the substitute part? A: The SPC564A80L7CFAR is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, supporting both manual and automated assembly processes.
