Substitute Part Grouping Explanation

Substitution eligibility for the SPC5644AF0MLU1 is determined by strict alignment of the following core parameters:

• Processor Architecture: e200z4 core (required match)
• Memory Configuration: 4MB FLASH, 192KB RAM (required match)
• Clock Speed: 150MHz (required match)
• Package Format: 176-LQFP (24x24) surface mount (required match)
• Temperature Range: -40°C to 125°C (required match)
• Environmental Compliance: ROHS3 Compliant (required match)

The substitute part SPC564A80L7CFAR meets all mandatory electrical and mechanical criteria for functional equivalence. Both devices share identical core processor architecture, memory capacity, operating frequency, and physical packaging specifications. Differences in supply voltage range, I/O count, and data converter specifications do not preclude substitution when system design accommodates these variations.

Parameter Comparison

Engineering Selection Recommendations

Both the SPC5644AF0MLU1 and SPC564A80L7CFAR are active production devices with ROHS3 compliance and equivalent core functionality. The SPC564A80L7CFAR carries automotive-grade qualification (AEC-Q100) and is suitable for applications requiring automotive reliability standards.

Selection between these parts should account for the following provided specifications:

• Supply Voltage Range: The SPC5644AF0MLU1 supports 1.14V to 5.25V, while the SPC564A80L7CFAR operates within 1.14V to 1.32V. System power supply design must align with the selected device's voltage specification.
• I/O Pin Count: The SPC564A80L7CFAR provides 118 I/O pins compared to 84 on the SPC5644AF0MLU1. Applications requiring additional I/O capacity benefit from the substitute part.
• Data Converter Configuration: The SPC5644AF0MLU1 includes 40 analog-to-digital converter channels (12-bit), while the SPC564A80L7CFAR provides 34 channels. System designs dependent on specific ADC channel counts must account for this difference.

Both devices maintain identical package geometry, thermal characteristics, and core processing capability, enabling direct substitution in applications where the noted parameter variations are compatible with system requirements.

Frequently Asked Questions (FAQ)

Q: Can SPC564A80L7CFAR replace SPC5644AF0MLU1 in existing designs?

A: Direct substitution is possible when system design accommodates the differences in supply voltage range (1.14V–1.32V vs. 1.14V–5.25V), I/O pin count (118 vs. 84), and analog converter channels (34 vs. 40). The core processor, memory configuration, clock speed, and physical package are identical.

Q: What are the critical parameters that must match for substitution?

A: The e200z4 processor core, 4MB FLASH memory, 192KB RAM, 150MHz clock speed, 176-LQFP package format, and -40°C to 125°C operating temperature range must remain constant. These parameters define functional equivalence.

Q: Are there connectivity differences between these parts?

A: Both devices support CANbus, EBI/EMI, LINbus, SCI, and SPI connectivity with identical peripheral support (DMA, POR, PWM, WDT). Connectivity specifications are equivalent.

Q: What is the significance of the AEC-Q100 qualification on the substitute part?

A: The SPC564A80L7CFAR carries automotive-grade qualification, indicating compliance with automotive reliability and quality standards. This certification is provided in the part specifications and may be relevant for automotive applications.

Q: How do the packaging and moisture sensitivity specifications compare?

A: Both parts use 176-LQFP (24x24) surface mount packaging with identical Moisture Sensitivity Level (MSL) rating of 3 (168 hours). Handling and storage requirements are equivalent.

Q: What should be verified before implementing a substitution?

A: System design must confirm compatibility with the substitute part's supply voltage range, I/O pin availability, and analog converter channel count. Physical PCB layout remains unchanged due to identical package geometry.
