Product details
Overview
R5F104PLGFA#50 from Renesas is a 100-pin LFQFP, 0.5 mm pitch, industrial-grade (G) 16-bit RL78/G14 microcontroller with 384 KB flash, 8 KB data flash, 32 KB RAM, and operation from −40°C to +105°C. It delivers 44 DMIPS at 32 MHz, consumes 66 μA/MHz active and 0.60 μA in RTC+LVD-only mode, and integrates UART, I²C, SPI, 12-bit RTC, 10-bit ADC (19 channels), and on-chip oscillators up to 32 MHz - used in motor control and industrial HMI systems.
For engineers reviewing the R5F104PLGFA#50 datasheet, R5F104PLGFA#50 pinout, R5F104PLGFA#50 application, or R5F104PLGFA#50 equivalent, key selection criteria include its 100-pin LFQFP-0.5 mm package, G-grade temperature rating, integrated event link controller (ELC), background data flash rewriting (BGO), and support for LIN-bus via UART - critical for deterministic real-time embedded designs.
Technical Context
The R5F104PLGFA#50 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs @ 32 MHz to 30.5 µs @ 32.768 kHz). It supports multiply/divide/accumulate instructions and features an address space of 1 MB with four register banks.
Its peripheral set includes 19–26 event signals routed via the Event Link Controller (ELC), Data Transfer Controller (DTC) with chain transfer, 12-channel 16-bit Timer Array Unit (TAU), and dual 8-bit D/A converters with real-time output - enabling precise analog waveform generation without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104MLGFB#50 | 80-pin LFQFP, 384 KB flash, 32 KB RAM, same G-grade temp range but fewer I/O (64 vs. 82) | Lower pin count suits compact control modules where UART/I²C channel count and ADC channels are reduced | Select when board space is constrained and full 100-pin I/O capability is unnecessary |
| R5F104PLGFA#30 | Identical functionality and pinout; differs only in packaging specification (tray vs. embossed tape) | No functional or application difference - purely logistics/supply chain distinction | Choose #30 for manual or semi-automated assembly; #50 for high-volume tape-and-reel SMT lines |
Compared with R5F104MLGFB#50, the R5F104PLGFA#50 provides 18 additional I/O pins and two extra UART channels - critical for complex HMI or multi-sensor aggregation. Versus R5F104PLGFA#30, the #50 variant enables automated pick-and-place with industry-standard embossed tape, reducing assembly cost at scale.

FAQ
What is the maximum operating frequency and associated DMIPS rating for the R5F104PLGFA#50?
The R5F104PLGFA#50 operates at up to 32 MHz and achieves 44 DMIPS performance. This metric is measured using the EEMBC CoreMark benchmark under standard conditions (code in flash, peripherals disabled). The RL78 core's 3-stage pipeline and optimized instruction set enable consistent throughput across voltage (1.6–5.5 V) and temperature (−40°C to +105°C) ranges - verified in Renesas' R01DS0053EJ0370 datasheet Section 1.1.
Does the R5F104PLGFA#50 support LIN bus communication, and if so, how is it implemented?
Yes, the R5F104PLGFA#50 supports LIN bus communication through its UART peripherals. Specifically, UART channels 0–3 include LIN-mode functionality per ISO 9141-2 and SAE J2602 standards - enabling automatic sync byte detection, checksum calculation, and break field generation. This capability is confirmed in the "Serial Interfaces" section of the R5F104PLGFA#50 datasheet (R01DS0053EJ0370, Page 1), and requires no external transceiver for basic node operation.
What are the data flash endurance and voltage requirements for rewriting the R5F104PLGFA#50?
The R5F104PLGFA#50 provides 8 KB of data flash memory rated for 1,000,000 write/erase cycles (typical) with operation supported across the full VDD range of 1.8 V to 5.5 V. Rewrites can occur in background (BGO) mode while executing code from main flash - a feature validated in the "Data Flash Memory" subsection (Section 1.1) of the official datasheet. No external high-voltage programming supply is required.
How many analog input channels does the R5F104PLGFA#50 support, and what ADC resolution is available?
The R5F104PLGFA#50 integrates a 10-bit successive approximation ADC with up to 19 analog input channels (ANI0–ANI19), including dedicated pins for internal temperature sensor and reference voltage monitoring. Input voltage range is 0 V to VDD, and the ADC supports programmable sampling clocks, scan modes, and hardware trigger sources - all documented in Section 1.1 "A/D Converter" of R01DS0053EJ0370.
Is the R5F104PLGFA#50 pin-compatible with other RL78/G14 variants, and what package type does it use?
The R5F104PLGFA#50 uses a 100-pin LFQFP package with 0.5 mm pitch (Renesas code PLQP0100KB-B), and is not pin-compatible with smaller-footprint RL78/G14 variants (e.g., 48- or 64-pin versions). Pin compatibility exists only within the same pin-count family - for example, R5F104PLGFA#50 shares identical pinout with R5F104PKAFB#50 and R5F104PLGFB#50, differing only in flash size and package variant (FA vs FB).
