Product details
Overview
R5F104GADFB#X0 from Renesas is a 48-pin LFQFP, industrial-grade (−40°C to +105°C) RL78/G14 16-bit MCU with 128 KB flash, 12 KB RAM, 8 KB data flash, and ultra-low-power operation (66 μA/MHz active, 0.60 μA RTC+LVD mode). It integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (16 channels), DAC, comparator, and real-time clock - deployed in motor control, sensor hubs, and industrial HMI.
For engineers reviewing the R5F104GADFB#X0 datasheet, R5F104GADFB#X0 pinout, R5F104GADFB#X0 application, or R5F104GADFB#X0 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm pitch package, G-grade temperature rating, 128 KB/12 KB/8 KB memory configuration, integrated analog peripherals, and support for SNOOZE mode power management in battery-constrained systems.
Technical Context
The R5F104GADFB#X0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz), and includes multiply/divide/accumulate instructions. Its memory subsystem comprises 128 KB code flash (1 KB blocks), 12 KB on-chip RAM, and 8 KB data flash with background operation (BGO) and 1M-cycle rewrite endurance.
Peripherals include 16-channel 10-bit ADC (VDD-referenced, internal 1.45 V reference, temp sensor), dual 8-bit DAC outputs (0–VDD range), two comparators (window/high-speed/low-speed modes), and event-driven architecture via Event Link Controller (ELC) linking 19–26 event sources to peripherals without CPU intervention.

The R5F104GADFB#X0 operates up to 32 MHz with a typical active current of 66 μA per MHz at VDD = 3.3 V and TA = 25°C. At full speed, this yields ~2.1 mA total active current. Its ultra-low-power STOP mode draws only 0.60 μA when RTC and LVD remain active - verified per R01DS0053EJ0370 Rev. 3.70, Section 1.1.
Does the R5F104GADFB#X0 support in-system programming and debugging?
Yes, the R5F104GADFB#X0 supports full in-system programming and debugging via its dedicated P50 (TOOLRxD) and P51 (TOOLTxD) pins, compatible with Renesas E2 emulator and CS+ IDE. It includes on-chip debug functionality, flash shield window, and boot swapping - enabling secure field firmware updates without external programmers.
What analog peripherals are integrated into the R5F104GADFB#X0?
The R5F104GADFB#X0 integrates a 10-bit ADC with 16 input channels and internal 1.45 V reference, two 8-bit DACs (0–VDD output range), two comparators with window/high-speed/low-speed modes, and an on-chip temperature sensor calibrated across −40°C to +105°C - all confirmed in Sections 1.1 and 1.3.6 of R01DS0053EJ0370.
Is the R5F104GADFB#X0 qualified for industrial temperature operation?
Yes, the "G" suffix in R5F104GADFB#X0 denotes industrial temperature grade: guaranteed operation from −40°C to +105°C ambient. This is explicitly defined in Section 1.2 (Ordering Information) and validated across all electrical characteristics in the datasheet's AC/DC specifications tables.
What package type and pin pitch does the R5F104GADFB#X0 use?
The R5F104GADFB#X0 uses a 48-pin LFQFP package (7 × 7 mm body, 0.5 mm pin pitch), identified by the "FB" suffix per Renesas' ordering guide. The #X0 packaging specification indicates embossed tape - confirmed in Table 1-1 (Page 5) and Figure 1-1 of R01DS0053EJ0370 Rev. 3.70.
