R5F52106CDFP#30 Equivalent & Substitute Parts

Part Overview

The R5F52106CDFP#30 is a 32-bit single-core RX microcontroller manufactured by Renesas Electronics Corporation, designed for embedded applications requiring moderate processing capability and integrated connectivity. This device features 256KB of FLASH program memory, 32KB of RAM, and 8KB of EEPROM, operating at 50MHz with a supply voltage range of 1.62V to 5.5V. The part is housed in a 100-LFQFP (14x14mm) surface-mount package with 84 I/O pins.

The R5F52106CDFP#30 is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and production requirements. Substitute parts must maintain identical electrical specifications, memory configurations, and package form factors to ensure direct compatibility in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the R5F52106CDFP#30 is determined by strict equivalence across the following critical parameters:

Memory Configuration: Program memory must be 256KB FLASH, EEPROM must be 8K x 8, and RAM must be 32K x 8. These specifications are non-negotiable for firmware compatibility and application functionality.

Processor Architecture: The RX core processor and 32-bit single-core configuration must be maintained. Alternative processor architectures are not substitutable.

Operating Frequency: The 50MHz clock speed must be preserved to maintain timing-dependent application behavior.

Electrical Specifications: Supply voltage range of 1.62V to 5.5V must be supported. Deviations in voltage tolerance affect circuit design compatibility.

Package and Pinout: The 100-LQFP (14x14mm) surface-mount package with 84 I/O pins must be identical. Package differences prevent direct board-level substitution.

Connectivity and Peripherals: EBI/EMI, I2C, SCI, and SPI interfaces, along with DMA, LVD, POR, PWM, and WDT peripherals, must be present and functionally equivalent.

The R5F52106CDFP#10 meets all these criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The R5F52106CDFP#10 is the appropriate substitute for the discontinued R5F52106CDFP#30. Both parts are manufactured by Renesas Electronics Corporation within the RX200 series and maintain complete parametric equivalence across all electrical, memory, connectivity, and package specifications.

The primary distinction between these parts is product status: the R5F52106CDFP#30 is discontinued at DiGi Electronics, while the R5F52106CDFP#10 maintains active product status with confirmed inventory availability (924 pieces in stock). This availability difference makes the R5F52106CDFP#10 the practical choice for new designs and production replenishment.

Both parts carry identical compliance certifications: ROHS3 compliance and REACH unaffected status. Moisture sensitivity level (MSL 3, 168 hours) is identical, requiring equivalent handling and storage protocols during manufacturing and assembly operations.

The substitution is direct and requires no circuit design modifications, firmware adjustments, or board layout changes. Pin assignments, electrical characteristics, and functional capabilities are identical between the two parts.
