R5F100LGDFB#30 Equivalent & Substitute Parts

Part Overview

The R5F100LGDFB#30 is a 16-bit RL78/G13 microcontroller manufactured by Renesas Electronics Corporation, featuring 128KB FLASH memory, 12KB RAM, and 8KB EEPROM. This device operates at 32MHz with integrated connectivity options including CSI, I2C, LINbus, and UART/USART interfaces. The part is actively produced and ROHS3 compliant, making it suitable for embedded control applications requiring low-power operation across the 1.6V to 5.5V supply range.

Substitute parts are necessary when the original part number becomes unavailable due to supply constraints, when alternative packaging formats better suit manufacturing requirements, or when design flexibility allows for equivalent performance specifications across the RL78/G13 product line.

Substitute Part Grouping Explanation

Substitution eligibility for the R5F100LGDFB#30 is determined by strict equivalence across the following critical parameters:

Core Electrical Specifications: All substitute parts maintain identical processor architecture (RL78), core size (16-Bit), operating frequency (32MHz), memory configuration (128KB FLASH, 12KB RAM, 8KB EEPROM), I/O count (48 pins), connectivity interfaces (CSI, I2C, LINbus, UART/USART), peripheral set (DMA, LVD, POR, PWM, WDT), analog capability (A/D 12x8/10b), and voltage supply range (1.6V ~ 5.5V).

Environmental Compliance: All substitute parts share identical operating temperature range (-40°C ~ 85°C), RoHS3 compliance status, MSL rating (3), and REACH unaffected status.

Package Variations: Substitutes differ only in supplier device package designation and physical footprint dimensions while maintaining the 64-LQFP pin count and surface mount mounting type. The R5F100LGDFB#30 uses 64-LFQFP (10x10) packaging, while substitutes include variants with 64-LQFP (12x12) and 64-LFQFP (10x10) configurations.
