Substitute Part Grouping Explanation

Substitution eligibility for the M30843FJGP#U5 is determined by strict alignment across the following critical parameters:

Core Functional Parameters:

• Processor architecture (M32C/80 core)
• Memory configuration (512KB FLASH, 24KB RAM, 4KB EEPROM)
• Clock speed (32MHz)
• Supply voltage range (3V ~ 5.5V)
• Peripheral set (CANbus, I2C, IEBus, SIO, UART/USART, DMA, PWM, WDT)
• Data converter specifications (A/D 26x10b, D/A 2x8b)

Physical & Environmental Parameters:

• Package type (100-LQFP)
• Mounting method (Surface Mount)
• Operating temperature range (-20°C ~ 85°C)
• Compliance certifications (ROHS3, REACH Unaffected)

The M30843FJGP#35 qualifies as a manufacturer-recommended substitute based on identical core processor, memory architecture, clock speed, connectivity, peripheral configuration, and package specifications. The primary distinction is product status transition from Obsolete to Active, indicating continued manufacturing and supply availability.

Parameter Comparison

Engineering Selection Recommendations

The M30843FJGP#35 is the manufacturer-recommended substitute for the obsolete M30843FJGP#U5. Both devices share identical core processor architecture, memory configuration, clock frequency, supply voltage specifications, and peripheral integration. The M30843FJGP#35 maintains Active product status, ensuring continued manufacturing support and supply chain availability.

The M30843FJGP#35 provides two additional I/O pins (87 versus 85), which represents a functional enhancement without introducing incompatibility. Both parts maintain REACH Unaffected compliance status. The substitute part is suitable for direct replacement in applications currently using the M30843FJGP#U5, with no modifications to firmware, PCB layout, or system architecture required.

Frequently Asked Questions (FAQ)

Q: Can the M30843FJGP#35 directly replace the M30843FJGP#U5 in existing designs?

A: Yes. Both parts share identical core processor, memory architecture, clock speed, supply voltage range, connectivity options, and peripheral configuration. The 100-LQFP package and Surface Mount specifications are identical. The M30843FJGP#35 provides two additional I/O pins, which does not create incompatibility with existing PCB designs.

Q: What is the significance of the product status change from Obsolete to Active?

A: The M30843FJGP#U5 is classified as Obsolete, indicating discontinued manufacturing and limited supply availability. The M30843FJGP#35 carries Active status, confirming ongoing production and reliable supply chain access. This transition is the primary reason for substitution in new procurement and long-term system support scenarios.

Q: Are there compliance or certification differences between these parts?

A: Both parts maintain REACH Unaffected status. The M30843FJGP#U5 is explicitly ROHS3 Compliant. RoHS compliance status for the M30843FJGP#35 is not specified in the provided data. Compliance verification should be confirmed with the manufacturer or authorized distributor before final component selection.

Q: How do the I/O pin counts differ, and does this affect compatibility?

A: The M30843FJGP#U5 provides 85 I/O pins, while the M30843FJGP#35 provides 87 I/O pins. This represents a functional enhancement. Existing designs utilizing 85 I/O pins will operate without modification. The additional pins on the M30843FJGP#35 remain available for future expansion or enhanced functionality without creating backward compatibility issues.

Q: Are there any firmware or software modifications required when switching to the M30843FJGP#35?

A: No firmware modifications are required. Both parts implement the identical M32C/80 core processor architecture, instruction set, memory organization, and peripheral interface specifications. Existing firmware compiled for the M30843FJGP#U5 will execute without modification on the M30843FJGP#35.
