Product details
Overview
R5F104LGAFB#V0 from Renesas is a 64-pin LFQFP (10 × 10 mm, 0.5 mm pitch), industrial-grade RL78/G14 16-bit MCU with 512 KB flash, 48 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at -40 to +105°C. It delivers 44 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.60 μA in RTC+LVD mode), and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (20 channels), and real-time clock - deployed in motor control, sensor hubs, and industrial HMI.
For engineers reviewing the R5F104LGAFB#V0 datasheet, R5F104LGAFB#V0 pinout, R5F104LGAFB#V0 application, or R5F104LGAFB#V0 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, G-grade temperature rating, integrated DTC/ELC peripherals, and support for background data flash rewriting with 1M-cycle endurance.
Technical Context
The R5F104LGAFB#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). Its on-chip high-speed oscillator offers ±1.0% accuracy across 1–64 MHz selections and full-voltage operation (1.8–5.5 V).
It integrates event-driven system control via Event Link Controller (ELC) supporting up to 26 event sources, and Data Transfer Controller (DTC) with chain transfer capability - enabling deterministic peripheral-to-memory transfers without CPU intervention during low-power operation.

FAQ
What is the maximum operating frequency and associated DMIPS rating for the R5F104LGAFB#V0?
The R5F104LGAFB#V0 achieves a maximum operating frequency of 32 MHz, delivering 44 DMIPS of processing performance. This is measured using the EEMBC CoreMark benchmark under standard conditions (code flash execution, no wait states). The RL78 core's 3-stage pipeline and optimized instruction set enable this efficiency at ultra-low power - critical for battery-powered industrial sensors where compute density per μA matters.
Does the R5F104LGAFB#V0 support in-system programming and secure firmware updates?
Yes, the R5F104LGAFB#V0 supports full in-system programming via its on-chip debug interface and includes flash shield window functionality to restrict write access to designated memory regions. It also implements boot swap capability for fail-safe firmware updates - ensuring the R5F104LGAFB#V0 can recover from corrupted images without external programmer intervention.
What are the key low-power modes supported by the R5F104LGAFB#V0, and what is the lowest achievable current draw?
The R5F104LGAFB#V0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.60 μA - verified across -40 to +105°C. This enables decade-long battery life in maintenance-free industrial loggers. SNOOZE mode allows selected peripherals (e.g., UART) to remain active for wake-up while CPU sleeps, further optimizing duty-cycled operation.
How many analog input channels does the 10-bit ADC in the R5F104LGAFB#V0 support, and does it include internal reference voltage?
The R5F104LGAFB#V0 integrates a 10-bit successive-approximation ADC with up to 20 analog input channels. It includes an internal 1.45 V reference voltage source, eliminating need for external precision references in most sensor signal conditioning applications. The ADC operates across the full 1.6–5.5 V supply range, maintaining linearity and monotonicity per datasheet specifications.
Is the R5F104LGAFB#V0 pin-compatible with other RL78/G14 variants in the same 64-pin LFQFP package?
Yes, all RL78/G14 devices in the 64-pin LFQFP-0.5mm package - including R5F104LGAFB#V0, R5F104LLAFB#V0, and R5F104LKAFB#V0 - share identical pinouts and electrical characteristics. This enables direct hardware reuse across memory/configurations, simplifying platform design and reducing PCB spin cycles when scaling flash/RAM requirements.
