Substitute Part Grouping Explanation

Substitution eligibility for the R5F564MFDDLC#21 is determined by strict parametric matching across the following critical criteria:

Core Architecture & Performance: The substitute part must maintain identical RXv2 core processor architecture, 32-bit single-core configuration, and 120MHz operating frequency to ensure software compatibility and performance parity.

Memory Configuration: Program memory must be 2MB FLASH, EEPROM must be 64K x 8, and RAM must be 552K x 8. These specifications are fundamental to application execution and cannot be altered without firmware modification.

Electrical Specifications: Supply voltage range must remain 2.7V ~ 3.6V. Operating temperature range must be -40°C ~ 85°C (TA).

Package & Mounting: The 177-TFLGA (8x8) package and surface mount configuration must be maintained for PCB compatibility and assembly process alignment.

Compliance & Certifications: RoHS3 compliance and active product status are required for regulatory and supply chain continuity.

The R5F564MFGDLC#21 meets all these criteria and qualifies as a parametric equivalent substitute.

Frequently Asked Questions (FAQ)

Q: Can R5F564MFGDLC#21 be used as a direct replacement for R5F564MFDDLC#21?

A: Yes. Both parts are parametric equivalents with identical core processor architecture, memory configuration, electrical specifications, package type, and operating characteristics. No design changes are required for substitution.

Q: Are there any differences in connectivity or peripheral support between these parts?

A: No. Both parts provide identical connectivity options (CANbus, EBI/EMI, Ethernet, I2C, LINbus, MMC/SD, SCI, SPI, SSI, UART/USART, USB) and peripheral support (DMA, LVD, POR, PWM, WDT).

Q: Do both parts support the same supply voltage range?

A: Yes. Both parts operate within the 2.7V ~ 3.6V supply voltage range and maintain identical electrical specifications.

Q: Is the 177-TFLGA (8x8) package identical for both parts?

A: Yes. Both parts use the same 177-TFLGA (8x8) surface mount package, ensuring PCB footprint and assembly process compatibility.

Q: What is the difference between these part numbers?

A: The difference lies in the internal designation characters (MFD vs MFG). Both designations refer to the same RX600 series microcontroller with identical functional and electrical specifications. The variation reflects Renesas' internal product coding but does not affect performance or compatibility.

Q: Are both parts RoHS3 compliant?

A: Yes. Both R5F564MFDDLC#21 and R5F564MFGDLC#21 are RoHS3 compliant and suitable for applications requiring regulatory compliance.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and supplier lead times. Both parts are active production items with equivalent long-term availability.
