Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the R5F10RFCAFP#50 is determined by strict parametric equivalence across the following critical criteria:

Core Architecture & Performance: The substitute part must maintain identical RL78 core processor architecture, 16-bit core size, and 24MHz operating speed to ensure software compatibility and performance characteristics.

Memory Configuration: Program memory must be exactly 16KB FLASH, EEPROM must be 2K x 8, and RAM must be 1K x 8. These specifications are fundamental to firmware deployment and runtime operation.

Electrical Specifications: Supply voltage range must remain 1.6V ~ 5.5V, and data converter specifications (A/D 7x10b) must be identical.

Connectivity & Peripherals: All communication interfaces (CSI, I2C, LINbus, UART/USART) and peripheral functions (DMA, LCD, LVD, POR, PWM, WDT) must be present and functionally equivalent.

Physical Package: The 44-LQFP (10x10) surface mount package is mandatory for PCB layout compatibility.

Compliance & Status: Both parts must maintain Active product status and equivalent RoHS3 compliance certification.

Frequently Asked Questions (FAQ)

Q: Can R5F10RFAAFP#50 be used as a direct replacement for R5F10RFCAFP#50 in existing designs?

A: Yes. Both parts are parametrically identical across all critical specifications including processor architecture, memory configuration, operating frequency, voltage supply range, connectivity interfaces, and peripheral functions. No design modifications are required for substitution.

Q: Are there any differences in the 44-LQFP package between these two part numbers?

A: No. Both components use the identical 44-LQFP (10x10) surface mount package with matching pin configurations, footprint requirements, and thermal characteristics. PCB layouts and assembly processes remain unchanged.

Q: Do both parts support the same firmware and software?

A: Yes. The identical RL78 core processor, 24MHz operating speed, and memory configuration ensure complete software compatibility. Firmware compiled for one part number executes identically on the other.

Q: What is the significance of the different part number suffixes (RFCAFP vs. RFAAFP)?

A: The suffix variations indicate different manufacturing batches or internal Renesas product line designations. These differences do not affect electrical performance, functionality, or compatibility. Both parts meet identical specifications and certifications.

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

A: No. Both parts maintain identical RoHS3 compliance status, Moisture Sensitivity Level 3 (168 Hours), REACH Unaffected status, and equivalent regulatory certifications. No additional compliance documentation or testing is required when substituting between these part numbers.

Q: Which part should be selected for new designs?

A: Selection should be based on current inventory availability and supplier lead times. Both parts are functionally and electrically equivalent, so either part number is suitable for new designs. Verify current stock levels with your supplier to optimize procurement timelines.
