Product details
Overview
R5F104LGAFB#30 from Renesas is a 64-pin LFQFP (0.5 mm pitch), 512 KB flash, 48 KB RAM RL78/G14 16-bit microcontroller operating from 1.6–5.5 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 control and sensor interface applications.
For engineers reviewing the R5F104LGAFB#30 datasheet, R5F104LGAFB#30 pinout, R5F104LGAFB#30 application, or R5F104LGAFB#30 equivalent, key selection considerations include its 64-pin LFQFP-0.5mm package, 512 KB code flash with 8 KB data flash, integrated RTC/calendar, 20-channel 10-bit ADC, and dual UART/LIN support for deterministic real-time embedded systems.
Technical Context
The R5F104LGAFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs min @32 MHz to 30.5 µs @32.768 kHz). It integrates a Data Transfer Controller (DTC) supporting chain transfer and an Event Link Controller (ELC) enabling direct peripheral-to-peripheral event routing without CPU intervention.
Its mixed-signal subsystem includes a 10-bit A/D converter with 20 input channels, internal 1.45 V reference and temperature sensor, dual 8-bit D/A outputs, two comparators with window mode, and programmable low-voltage detection (14-level LVD) - all operating across the full –40°C to +105°C industrial temperature range (G-grade).

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104LLAFB#30 | Same 64-pin LFQFP-0.5mm package, identical 512 KB flash/48 KB RAM, but rated for –40°C to +85°C (D-grade) instead of +105°C (G-grade) | Suitable for consumer or lower-ambient industrial environments where extended temperature is not required | Select when full G-grade thermal margin is unnecessary and cost optimization is prioritized |
| R5F104LKAFB#30 | Same package and temperature grade, but reduced 384 KB flash and 32 KB RAM; retains all peripheral sets including RTC, ADC, DAC, and UART/LIN | Applicable where firmware footprint is <384 KB and RAM usage ≤32 KB, e.g., simpler control loops or legacy porting | Choose when application complexity allows memory reduction without sacrificing peripheral functionality or thermal rating |
