Product details
Overview
R5F104LFAFP#30 from Renesas is a 64-pin LQFP-0.65 mm pitch, 512 KB flash, 48 KB RAM RL78/G14 16-bit microcontroller operating from 1.6 V to 5.5 V, delivering 44 DMIPS at 32 MHz with ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD mode), used in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F104LFAFP#30 datasheet, R5F104LFAFP#30 pinout, R5F104LFAFP#30 application, or R5F104LFAFP#30 equivalent, key selection criteria include its 64-pin LQFP package, 512 KB code flash with 8 KB data flash, integrated RTC + LVD, 20-channel 10-bit ADC, and dual UART/LIN support for deterministic serial communication in resource-constrained embedded systems.
Technical Context
The R5F104LFAFP#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz), and includes multiply/divide/accumulate instructions within a 1 MB address space. It integrates a Data Transfer Controller (DTC) with chain transfer and an Event Link Controller (ELC) enabling 19–26 peripheral event linkings without CPU intervention.
Its mixed-signal subsystem includes an 8/10-bit ADC with internal 1.45 V reference and temperature sensor, dual 8-bit DACs with real-time output, two comparators with window/high-speed/low-speed modes, and up to 20 analog inputs - all operable across the full 1.6–5.5 V supply range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104LGAFA | Same 64-pin LQFP package, 512 KB flash, but rated for −40°C to +85°C (A-grade) vs. −40°C to +105°C (G-grade) of R5F104LFAFP#30 | Targeted at consumer/home appliances; lacks extended temperature qualification for industrial enclosures | Select when ambient operating temperature remains ≤85°C and cost sensitivity outweighs extended temp margin |
| R5F104LKAFP#30 | Identical package and temperature grade, but with 384 KB flash + 8 KB data flash instead of 512 KB; same 48 KB RAM and peripheral set | Used where firmware footprint <384 KB suffices and BOM cost reduction is prioritized over future firmware headroom | Choose when application firmware size is confirmed ≤350 KB and long-term field updates are not required |
Compared with R5F104LGAFA and R5F104LKAFP#30, the R5F104LFAFP#30 provides maximum flash headroom (512 KB) and guaranteed operation up to +105°C - critical for sealed industrial enclosures and designs requiring multi-version firmware storage or secure bootloader partitions.

The R5F104LFAFP#30 operates up to 32 MHz with a high-speed on-chip oscillator accurate to ±1.0% over 1.8–5.5 V and −20°C to +85°C. At this frequency, active current is 66 μA/MHz (2.11 mA typical at 32 MHz). In STOP mode with only RTC and LVD active, it draws 0.60 μA - verified per R01DS0053EJ0370 Rev. 3.70, Section 1.1.
Does the R5F104LFAFP#30 support LIN bus communication, and which UART channels implement it?
Yes, the R5F104LFAFP#30 supports LIN 2.2A and SAE J2602 protocols on UART2 and UART3 channels. These UARTs include dedicated LIN break detection, sync field handling, and checksum calculation hardware - confirmed in Section 1.1 "Serial Interfaces" of the R01DS0053EJ0370 datasheet.
What is the flash memory organization and write endurance specification for the R5F104LFAFP#30?
The R5F104LFAFP#30 contains 512 KB of code flash memory organized in 1 KB blocks, plus 8 KB of data flash memory. Data flash supports background operation (BGO) and guarantees 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V - specified in Section 1.1 "Data Flash Memory" of R01DS0053EJ0370 Rev. 3.70.
How many analog input channels does the R5F104LFAFP#30 support, and what ADC resolution and reference options are available?
The R5F104LFAFP#30 supports up to 20 analog input channels (ANI0–ANI19) with an 8/10-bit successive approximation ADC. It accepts VDD as reference or uses an internal 1.45 V reference; temperature sensor and AVREFP/M pins are also accessible - detailed in Section 1.1 "A/D Converter" of R01DS0053EJ0370 Rev. 3.70.
Is the R5F104LFAFP#30 pin-compatible with other RL78/G14 variants in the same 64-pin LQFP package?
Yes, all RL78/G14 devices in the 64-pin LQFP-0.65 mm pitch package (e.g., R5F104LCAFA, R5F104LGAFA, R5F104LKAFA) share identical pinouts and electrical characteristics per pin - confirmed in Table 1-1 and Figures 1-12 through 1-14 of R01DS0053EJ0370 Rev. 3.70.
