Product details
Overview
R5F104LGGLA#U0 from Renesas is a 64-pin FLGA-packaged RL78/G14 16-bit MCU with 512 KB flash, 8 KB data flash, 48 KB RAM, and industrial-grade operation (−40°C to +105°C). It delivers 44 DMIPS at 32 MHz, supports ultra-low-power modes (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (20 ch), and RTC with calendar function - deployed in motor control and smart sensor nodes.
For engineers reviewing the R5F104LGGLA#U0 datasheet, R5F104LGGLA#U0 pinout, R5F104LGGLA#U0 application, or R5F104LGGLA#U0 equivalent, key selection criteria include its FLGA-64 package footprint, −40°C to +105°C extended temperature rating, integrated data flash with 1M rewrite cycles, and hardware event linking via ELC for deterministic peripheral coordination.
Technical Context
The R5F104LGGLA#U0 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). Its Event Link Controller (ELC) enables direct hardware-triggered peripheral activation without CPU intervention, reducing latency and interrupt overhead.
It features a dual-voltage domain I/O structure supporting 1.8/2.5/3.0 V interface compatibility, on-chip high-accuracy oscillator (±1.0% over −20°C to +85°C), and background operation (BGO) for concurrent code execution during data flash rewriting - critical for firmware-over-the-air updates in field-deployed devices.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104LLGFB#30 | LFQFP-64 (10×10 mm, 0.5 mm pitch); identical flash/RAM/peripherals but different package and temperature grade (G-grade same). | Requires PCB re-layout due to larger footprint and different thermal pad; suitable where manual assembly or heat dissipation is prioritized. | Select when board space permits larger QFP and hand-soldering is preferred over FLGA reflow. |
| R5F104LKGLA#U0 | FLGA-64 package, same footprint; 384 KB flash (vs. 512 KB), otherwise identical peripheral set and electrical specs. | Valid for applications with smaller firmware image size (<384 KB) and no future feature expansion requirements. | Choose for cost-optimized designs where full 512 KB flash is unnecessary and BOM cost reduction is critical. |
Compared with R5F104LLGFB#30 and R5F104LKGLA#U0, the R5F104LGGLA#U0 provides maximum code density in the smallest 64-pin form factor, enabling compact, thermally efficient designs for space-constrained industrial edge nodes - without sacrificing peripheral richness or extended temperature capability.

FAQ
What is the operating voltage range of the R5F104LGGLA#U0?
The R5F104LGGLA#U0 operates from 1.6 V to 5.5 V, enabling direct interface with diverse power domains including single-cell Li-ion (3.0–3.7 V), 3.3 V logic, and legacy 5 V systems. This wide range eliminates level-shifting components in mixed-voltage designs and supports brown-out resilience down to 1.6 V.
Does the R5F104LGGLA#U0 support in-system programming via standard interfaces?
Yes, the R5F104LGGLA#U0 supports in-system programming via its on-chip debug interface using the Renesas E2 emulator or compatible tools. It also enables self-programming of both code and data flash memory through the flash self-programming library - allowing field firmware updates without external programmers.
How many UART channels does the R5F104LGGLA#U0 include, and do they support LIN bus?
The R5F104LGGLA#U0 includes four UART channels, all of which support LIN bus physical layer compliance (LIN-bus supported per datasheet). Each UART can operate independently with programmable baud rates, break detection, and sync byte handling - ideal for automotive body electronics and distributed sensor networks.
What is the maximum ADC sampling rate achievable with the R5F104LGGLA#U0's 10-bit ADC?
The R5F104LGGLA#U0's 10-bit ADC achieves a maximum conversion time of 1.2 μs per sample (≈833 kSPS) when operating at 32 MHz system clock with shortest sampling time setting. Real-world throughput depends on channel count and software overhead, but hardware triggers via ELC ensure deterministic timing for closed-loop control.
Is the R5F104LGGLA#U0 pin-compatible with other RL78/G14 variants in FLGA-64 packaging?
Yes, the R5F104LGGLA#U0 shares identical pinout and electrical characteristics with all other RL78/G14 FLGA-64 variants (e.g., R5F104LKGLA#U0, R5F104LLGLA#U0), enabling drop-in replacement within the same memory/peripheral configuration group - provided firmware accounts for differences in flash size and feature enablement.
