R5F64189PFD Equivalent & Substitute Parts

Part Overview

The R5F64189PFD is a 16/32-bit microcontroller from Renesas Electronics Corporation based on the R32C/100 core architecture. This device integrates 1MB of Flash program memory, 63KB of RAM, and 8KB of EEPROM within a 144-LQFP surface mount package. The microcontroller supports multiple connectivity interfaces including CANbus, I2C, UART/USART, and EBI/EMI, making it suitable for industrial and embedded control applications.

The R5F64189PFD is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for systems currently deployed or in development phases.

Substitute Part Grouping Explanation

Substitute parts for the R5F64189PFD are identified based on strict parametric equivalence across the following critical criteria:

• Core processor architecture (R32C/100)
• Core size (16/32-Bit)
• Operating speed (50MHz)
• Program memory capacity and type (1MB FLASH)
• RAM and EEPROM sizes (63K x 8 and 8K x 8 respectively)
• Supply voltage range (3V ~ 5.5V)
• Operating temperature range (-40°C ~ 85°C)
• Package type and pin count (144-LQFP, 20x20)
• I/O count (120 pins)
• Connectivity interfaces (CANbus, EBI/EMI, I2C, IEBus, UART/USART)
• Peripheral set (DMA, LVD, PWM, WDT)
• Data converter specifications (A/D 34x10b, D/A 2x8b)

Substitute parts must maintain full compatibility across all these parameters to ensure functional and electrical interchangeability without design modifications.

Parameter Comparison

Engineering Selection Recommendations

Both R5F64179DFD#2B and R5F64189PFD#UB are parametrically equivalent to the R5F64189PFD across all critical electrical and mechanical specifications. Selection between these alternatives should be based on the following factors:

R5F64189PFD#UB is the preferred substitute. This part carries the same base product number (R5F64189) as the original device and maintains active product status. It is ROHS3 compliant with Moisture Sensitivity Level 1 (unlimited storage), indicating superior handling characteristics and long-term reliability. REACH compliance is confirmed.

R5F64179DFD#2B is an alternative equivalent based on the M16C/R32C/100/117 series variant. This part is also active and ROHS3 compliant but carries Moisture Sensitivity Level 3 (168 hours), requiring controlled storage conditions. REACH compliance is confirmed. This option is suitable for applications where the series variant difference does not impact system requirements.

Both substitutes support identical core functionality, memory configuration, connectivity interfaces, and peripheral sets. Design integration requires no modifications to PCB layout, firmware, or system architecture when transitioning from the obsolete R5F64189PFD to either active substitute.

Frequently Asked Questions (FAQ)

Q: Can R5F64179DFD#2B and R5F64189PFD#UB be used interchangeably with R5F64189PFD?

A: Both parts are parametrically equivalent across all critical specifications including core processor, memory configuration, operating speed, supply voltage, temperature range, package type, and peripheral set. They are electrically and mechanically interchangeable without design modifications.

Q: What is the difference between the M16C/R32C/100/117 and M16C/R32C/100/118 series variants?

A: The provided data specifies series designations but does not detail functional differences between these variants. Both maintain identical electrical and mechanical parameters relevant to substitution. Consult Renesas Electronics technical documentation for series-specific feature variations if required.

Q: Why is R5F64189PFD#UB recommended over R5F64179DFD#2B?

A: R5F64189PFD#UB shares the same base product number (R5F64189) as the original part, maintaining design lineage. Its Moisture Sensitivity Level 1 rating provides unlimited storage capability compared to the 168-hour limitation of R5F64179DFD#2B, reducing supply chain handling complexity and risk.

Q: Are there compliance or certification differences between the substitutes?

A: Both substitutes are ROHS3 compliant and REACH unaffected. R5F64189PFD#UB includes ECCN and HTSUS classifications. Moisture sensitivity differs: R5F64189PFD#UB (MSL 1) versus R5F64179DFD#2B (MSL 3). Verify compliance requirements for your specific application and region.

Q: What is the package compatibility between these parts?

A: All three parts use identical 144-LQFP (20x20) surface mount packaging with 120 I/O pins. PCB footprints, solder reflow profiles, and assembly processes require no modification.

Q: Is firmware compatibility guaranteed?

A: All parts share the R32C/100 core processor architecture and identical peripheral configuration. Firmware compiled for R5F64189PFD executes without modification on both substitute parts.
