Product details
Overview
R5F104FDAFP#30 from Renesas is a 44-pin LQFP, 96 KB flash, 12 KB RAM RL78/G14 16-bit microcontroller with ultra-low power operation (66 μA/MHz), integrated 10-bit ADC (16 channels), RTC, and dual UART/SPI/I²C interfaces - deployed in battery-powered industrial sensor nodes and smart metering front-ends.
For engineers reviewing the R5F104FDAFP#30 datasheet, R5F104FDAFP#30 pinout, R5F104FDAFP#30 application, or R5F104FDAFP#30 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm pitch package, -40°C to +85°C industrial temperature grade (D suffix), 96 KB code flash with data flash shield, and hardware event linking via ELC for deterministic peripheral coordination.
Technical Context
The R5F104FDAFP#30 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz), and includes on-chip debug, self-programming with boot swapping, and background data flash rewriting (BGO).
Its peripheral set integrates an Event Link Controller (ELC) enabling direct hardware-triggered peripheral activation without CPU intervention, plus a Data Transfer Controller (DTC) supporting chain transfer across up to 26 event sources - critical for low-latency sensor data acquisition and real-time control loops.

The R5F104FDAFP#30 operates up to 32 MHz with a typical active current of 66 μA/MHz at VDD = 3.3 V and TA = 25°C. At full speed, this equates to ~2.1 mA total active current. Its ultra-low-power STOP mode draws only 0.60 μA with RTC and LVD active - verified per R01DS0053EJ0370 Rev. 3.70 Section 1.1.
Does the R5F104FDAFP#30 support in-system programming and secure firmware updates?
Yes, the R5F104FDAFP#30 supports full in-system programming via on-chip debug interface and includes flash shield window protection, boot swapping, and block erase prohibition. These features enable secure field firmware updates without exposing code - confirmed in Section 1.1 "Code Flash Memory" of the official datasheet.
How many serial communication interfaces does the R5F104FDAFP#30 integrate, and are they independently configurable?
The R5F104FDAFP#30 integrates three UART channels (one LIN-capable), three CSI/SPI modules, and four I²C interfaces - all independently configurable via dedicated registers and peripheral I/O redirection. Pin multiplexing allows flexible assignment without hardware changes, as documented in Section 1.3.5 pinout and Section 1.1 "Serial Interfaces".
What is the ADC resolution, input channel count, and reference voltage option for the R5F104FDAFP#30?
The R5F104FDAFP#30 features a 10-bit successive-approximation ADC with 16 analog input channels, selectable internal reference voltage (1.45 V), and support for external reference. It operates across the full 1.6–5.5 V supply range - specifications confirmed in Section 1.1 "A/D Converter" of R01DS0053EJ0370 Rev. 3.70.
Is the R5F104FDAFP#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-0.8 mm pitch package - including R5F104FDAFP#30, R5F104GDAFP#30, and R5F104FCAFP#30 - share identical pinouts, electrical characteristics, and peripheral mapping. This enables memory-size-based scalability without PCB redesign, per Table 1-1 and Section 1.3.5 of the datasheet.
