Key Parameters

Substitute Part Grouping Explanation

Substitution of the M30840SGP#U5 is determined by strict alignment of the following electrical and mechanical parameters:

• Core processor architecture (M32C/80)
• Core size (16/32-Bit)
• Operating frequency (32MHz)
• Package form factor (100-LFQFP, 14x14mm)
• Program memory type (ROMless)
• RAM capacity (10K x 8)
• Supply voltage range (3V ~ 5.5V)
• Operating temperature range (-20°C ~ 85°C)
• Connectivity protocols (CANbus, I2C, IEBus, SIO, UART/USART)
• Peripheral set (DMA, PWM, WDT)

The M30840SGP#35 qualifies as a direct substitute based on matching all core electrical specifications and package requirements. Differences in I/O count and A/D converter channels do not preclude substitution when the application does not require the full I/O or analog input capacity of the substitute part.

Parameter Comparison

Engineering Selection Recommendations

The M30840SGP#35 is the manufacturer-recommended substitute for the obsolete M30840SGP#U5. Both parts maintain identical core electrical specifications, package geometry, and peripheral architecture, ensuring direct functional compatibility at the system level.

The transition from M30840SGP#U5 to M30840SGP#35 is supported by:

• Active product status of M30840SGP#35, ensuring long-term availability and supply chain continuity
• Identical REACH compliance status, maintaining regulatory alignment
• Matching ROHS3 compliance framework
• Identical ECCN and HTSUS classifications, preserving export and import compliance
• Superset I/O and analog converter capacity, providing design flexibility without requiring architectural changes

Applications utilizing the full 45 I/O pins and 10 A/D channels of the M30840SGP#U5 will function with the M30840SGP#35 without modification, as the substitute part provides 123 I/O pins and 34 A/D channels. Designs utilizing a subset of available I/O and analog resources will operate identically on both parts.

Frequently Asked Questions (FAQ)

Q: Can M30840SGP#35 be used as a direct replacement for M30840SGP#U5 in existing designs?

A: Yes. Both parts share identical core processor architecture, operating frequency, package form factor, supply voltage range, and peripheral set. The M30840SGP#35 provides additional I/O and analog converter resources but does not require design modifications for compatibility.

Q: What is the significance of the different I/O counts (45 vs. 123)?

A: The M30840SGP#U5 provides 45 I/O pins, while the M30840SGP#35 provides 123 I/O pins. This difference reflects internal die variants within the same package. Designs utilizing fewer than 45 I/O pins will function identically on both parts. Designs requiring more than 45 I/O pins benefit from the expanded capacity of the M30840SGP#35.

Q: Are the A/D converter specifications compatible?

A: The M30840SGP#U5 integrates 10 A/D channels at 10-bit resolution, while the M30840SGP#35 provides 34 A/D channels at 10-bit resolution. Both parts maintain 10-bit resolution. Applications using fewer than 10 A/D channels will operate identically on both parts. Applications requiring additional analog input capacity benefit from the M30840SGP#35.

Q: Is the 100-LFQFP package identical between both parts?

A: Yes. Both parts use the 100-LFQFP package with 14x14mm dimensions, ensuring identical PCB footprint and assembly compatibility.

Q: What is the product status difference, and why does it matter?

A: The M30840SGP#U5 is classified as obsolete, indicating end-of-life status and limited availability. The M30840SGP#35 is active, ensuring ongoing manufacturing, supply chain availability, and long-term design support. For new designs or production continuity, the M30840SGP#35 is the recommended choice.

Q: Are compliance certifications maintained across both parts?

A: Yes. Both parts maintain identical ROHS3 compliance, REACH unaffected status, and matching ECCN and HTSUS classifications, ensuring regulatory and export compliance alignment.
