Product details
Overview
R5F104FGAFP#30 from Renesas is a 44-pin LQFP-packaged RL78/G14 16-bit MCU with 96 KB flash, 12 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at -40 to +85°C (industrial grade D). It delivers 44 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (20 ch), and real-time clock.
For engineers reviewing the R5F104FGAFP#30 datasheet, R5F104FGAFP#30 pinout, R5F104FGAFP#30 application, or R5F104FGAFP#30 equivalent, this page provides verified technical context, package mapping, functional pin roles, low-power design trade-offs, and industrial-grade timing/peripheral compatibility for embedded control selection.
Technical Context
The R5F104FGAFP#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode), plus multiply/divide/accumulate instructions and 1 MB address space. It uses on-chip high-accuracy ±1.0% oscillator (selectable 1–64 MHz) and supports HALT/STOP/SNOOZE low-power modes.
Peripheral integration includes Event Link Controller (ELC) for 19–26 event signal routing, Data Transfer Controller (DTC) with chain transfer, background operation (BGO) for data flash rewriting, and dual-voltage interface capability (1.8/2.5/3 V logic compatibility). The device supports LIN-bus via UART and includes on-chip BCD correction and key interrupt functions.

The R5F104FGAFP#30 operates up to 32 MHz with an on-chip high-speed oscillator, delivering 44 DMIPS performance. This is measured using the EEMBC CoreMark benchmark and reflects sustained throughput under typical industrial workloads with peripheral activity and interrupt servicing.
Does the R5F104FGAFP#30 support LIN bus communication, and which peripheral implements it?
Yes, the R5F104FGAFP#30 supports LIN bus communication through its UART channels - specifically UART2 (pins P13/P14) and UART0 (pins P50/P51), both configurable for LIN 2.2A protocol with break detection and sync field handling per ISO 17987-4.
What are the flash memory organization and security features of the R5F104FGAFP#30?
The R5F104FGAFP#30 contains 96 KB of code flash organized in 1 KB blocks, with hardware-level security enabling block erase/write prohibition. It supports on-chip debug lock, flash shield window for protected boot code, and self-programming with boot swapping - all verified in Renesas' Flash Self-Programming Library R20UT2944.
How does the R5F104FGAFP#30 achieve ultra-low power consumption in STOP mode?
The R5F104FGAFP#30 achieves 0.60 μA STOP mode current by retaining only the real-time clock (RTC) and low-voltage detector (LVD) circuits while powering down the CPU, flash, RAM, and all peripherals. This state is entered via software command and exited by RTC alarm or external interrupt - validated across -40 to +85°C.
Which analog peripherals are integrated into the R5F104FGAFP#30, and what are their key specifications?
The R5F104FGAFP#30 integrates a 10-bit ADC with 20 input channels, internal 1.45 V reference, and on-die temperature sensor; an 8-bit DAC with two output channels (0–VDD range); and up to two comparators with selectable internal/external reference.
