R5F566TFGDFP#10 Equivalent & Substitute Parts

Part Overview

The R5F566TFGDFP#10 is a 32-bit single-core microcontroller from Renesas Electronics Corporation belonging to the RX66T series. This embedded IC features 512KB FLASH program memory, 128KB RAM, and 32KB EEPROM, operating at 160MHz with comprehensive connectivity options including CANbus, USB, SPI, I2C, and UART/USART interfaces. The device is housed in a 100-LFQFP surface mount package and maintains active product status with full RoHS3 compliance. Equivalent substitute parts are necessary to address inventory availability, lead time constraints, or packaging format requirements while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the R5F566TFGDFP#10 are determined by strict equivalence across all electrical and mechanical parameters. The substitution logic is based on the following criteria:

Core Electrical Parameters:

• Identical RXv3 core processor architecture
• Matching 32-bit single-core configuration
• Identical 160MHz operating frequency
• Identical program memory: 512KB FLASH
• Identical EEPROM: 32K x 8
• Identical RAM: 128K x 8
• Identical voltage supply range: 2.7V ~ 5.5V
• Identical data converter specifications: 22x12b A/D and 2x12b D/A
• Identical I/O count: 69 pins
• Identical connectivity interfaces: CANbus, EBI/EMI, I2C, LINbus, MMC/SD, SCI, SPI, SSI, UART/USART, USB
• Identical peripheral features: DMA, LVD, POR, PWM, WDT

Mechanical Parameters:

• Identical package type: 100-LQFP
• Identical supplier device package: 100-LFQFP (14x14)
• Identical surface mount mounting type
• Identical operating temperature range: -40°C ~ 85°C

Compliance Parameters:

• Identical RoHS3 compliance status
• Identical MSL rating: 3 (168 Hours)
• Identical REACH status: REACH Unaffected

All substitute parts maintain the same base product number (R5F566) and series designation (RX66T), with variations only in packaging format designators (#10, #30) and internal code designations (TFGDFP, TFCDFP).

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed—R5F566TFCDFP#10, R5F566TFCDFP#30, and R5F566TFGDFP#30—are direct parametric equivalents to the R5F566TFGDFP#10. Each part maintains identical electrical specifications, mechanical dimensions, and compliance certifications. Selection among these equivalents is based on inventory availability and packaging format requirements rather than functional differences.

All parts maintain active product status with Renesas Electronics Corporation and carry full RoHS3 compliance certification. The MSL rating of 3 (168 Hours) applies uniformly across all variants, establishing identical moisture handling requirements for storage and assembly operations. REACH compliance status is consistent across all parts, with no restricted substances identified.

The variations in part number designators (TFGDFP versus TFCDFP and #10 versus #30) reflect internal Renesas packaging format classifications that do not affect electrical performance or mechanical compatibility. These designations relate to packaging configuration and supply format only.

Frequently Asked Questions (FAQ)

Q: Are all listed substitute parts electrically identical to the R5F566TFGDFP#10?

A: Yes. All substitute parts—R5F566TFCDFP#10, R5F566TFCDFP#30, and R5F566TFGDFP#30—share identical electrical specifications including processor architecture, clock speed, memory configuration, voltage supply range, data converter specifications, I/O count, and peripheral features.

Q: What do the designators #10 and #30 represent in the part numbers?

A: The #10 and #30 designators indicate packaging format classifications assigned by Renesas Electronics. These designations do not affect electrical performance or mechanical pin compatibility.

Q: Are the TFGDFP and TFCDFP code designations functionally different?

A: No. The TFGDFP and TFCDFP designations are internal Renesas classifications related to packaging configuration. All parts with these designations maintain identical electrical and mechanical specifications.

Q: Can I substitute any of these parts directly on a PCB designed for the R5F566TFGDFP#10?

A: Yes. All substitute parts use the identical 100-LFQFP (14x14) package with 100 pins in the same physical configuration. Direct PCB substitution is supported without layout modifications.

Q: Do all parts have the same moisture sensitivity requirements?

A: Yes. All parts carry an MSL rating of 3 (168 Hours), establishing identical moisture handling, storage, and assembly requirements.

Q: Are there any compliance differences between the main part and substitutes?

A: No. All parts maintain identical RoHS3 compliance status, REACH unaffected status, and operating temperature range of -40°C to 85°C.

Q: What is the primary reason to select one substitute over another?

A: Selection is based on inventory availability and lead time. The R5F566TFCDFP#30 variant shows significantly higher inventory levels (105,342 pieces) compared to other options, making it the preferred choice for immediate availability requirements.
