For engineers reviewing the R5F104FDGFP#30 datasheet, R5F104FDGFP#30 pinout, R5F104FDGFP#30 application, or R5F104FDGFP#30 equivalent, key selection criteria include its -40°C to +105°C industrial-grade temperature range (G-suffix), integrated 10-bit 20-channel ADC, dual UART/LIN support, and hardware event-link controller for deterministic peripheral coordination.
Technical Context
The R5F104FDGFP#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-power mode). It integrates a 19–26-source Event Link Controller (ELC) that enables direct peripheral-to-peripheral triggering without CPU intervention.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104FDGFP#30?
The R5F104FDGFP#30 operates at up to 32 MHz with a measured performance of 44 DMIPS. This rating is achieved using the RL78 CPU core's 3-stage pipeline and optimized instruction set, enabling deterministic execution of real-time control algorithms in industrial applications. The R5F104FDGFP#30 maintains this performance across its full 1.6–5.5 V supply range and -40°C to +105°C temperature envelope.
Does the R5F104FDGFP#30 support LIN communication, and which peripheral handles it?
Yes, the R5F104FDGFP#30 supports LIN communication through its UART2 peripheral (pins P13/TxD2 and P14/RxD2), which includes hardware-level LIN protocol features such as automatic sync-field detection, checksum calculation, and break signal generation. This allows the R5F104FDGFP#30 to function as a fully compliant LIN slave node without external protocol assist hardware.
What are the data flash endurance and rewrite voltage range for the R5F104FDGFP#30?
The R5F104FDGFP#30 provides 4 KB of on-chip data flash rated for 1,000,000 write/erase cycles (typical) with background operation (BGO) enabled. Rewrites are supported across the full VDD range of 1.8–5.5 V, allowing in-system parameter updates during normal operation without halting application code execution - a capability confirmed in the R01DS0053EJ0370 datasheet section 1.1.
How many analog input channels does the R5F104FDGFP#30 ADC support, and what reference options are available?
The R5F104FDGFP#30 integrates a 10-bit successive approximation register (SAR) ADC with up to 20 analog input channels. It supports both external reference inputs (AVREFP/AVREFM pins) and an internal 1.45 V reference voltage, enabling flexible measurement configurations for sensors with varying output ranges. The ADC also includes an integrated temperature sensor usable for system thermal monitoring.
Is the R5F104FDGFP#30 pin-compatible with other RL78/G14 variants in the same 44-pin LQFP package?
Yes, all RL78/G14 devices in the 44-pin LQFP package (e.g., R5F104FDGFP#30, R5F104FGGFP#30, R5F104GHGFP#30) share identical pinouts and electrical characteristics. This allows direct substitution within the same footprint when memory or peripheral requirements change - provided firmware is recompiled to match the target device's flash/RAM map and feature enablement.
