Product details
Overview
R5F104GGAFB#V0 from Renesas is a 48-pin LFQFP, 0.5 mm pitch, industrial-grade (−40°C to +105°C) RL78/G14 16-bit MCU with 96 KB flash, 12 KB RAM, and 8 KB data flash. It delivers 44 DMIPS at 32 MHz, operates from 1.6–5.5 V, and achieves 66 μA/MHz active current and 0.60 μA RTC-only standby-targeting battery-powered industrial sensors and motor control interfaces.
For engineers reviewing the R5F104GGAFB#V0 datasheet, R5F104GGAFB#V0 pinout, R5F104GGAFB#V0 application, or R5F104GGAFB#V0 equivalent, key selection criteria include its integrated 10-bit ADC (20-channel), dual UART/LIN support, real-time clock with calendar, low-power STOP/HALT modes, and hardware DTC/ELC for deterministic peripheral triggering in resource-constrained embedded systems.
Technical Context
The R5F104GGAFB#V0 implements the RL78 CPU core-a CISC architecture with 3-stage pipeline, configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz), and multiply/divide/accumulate instructions. Its memory subsystem includes 96 KB on-chip code flash (1 KB block size, security-protected erase), 8 KB data flash with background operation (BGO), and 12 KB RAM.
Peripherals are orchestrated via Event Link Controller (ELC) supporting up to 26 event sources and Data Transfer Controller (DTC) with chain transfer. Clocking uses a high-accuracy ±1.0% on-chip oscillator (1–64 MHz selectable), complemented by external crystal support (X1/X2, XT1/XT2) and subsystem clocks for RTC and LVD.

Pins P00 (TxD1), P01 (RxD1), P13 (TxD2), and P14 (RxD2) are commonly configured for LIN transceiver interfacing, per section 1.3.6 of the R5F104GGAFB#V0 datasheet.
What are the memory configuration details-flash, data flash, and RAM-for the R5F104GGAFB#V0?
The R5F104GGAFB#V0 integrates 96 KB of code flash memory, 8 KB of data flash memory, and 12 KB of on-chip RAM. These values are explicitly listed in Table 1-1 of the RL78/G14 datasheet (R01DS0053EJ0340) under the "R5F104xG" row for 48-pin devices, confirming allocation for this exact part number.
Is the R5F104GGAFB#V0 qualified for industrial temperature range, and what is the specified range?
Yes, the R5F104GGAFB#V0 carries the 'G' grade suffix, indicating qualification for −40°C to +105°C ambient operating temperature-explicitly designated for industrial applications per Renesas ordering information (Section 1.2). This rating is validated across electrical parameters including ADC accuracy, oscillator stability, and flash endurance.
How does the R5F104GGAFB#V0 implement low-power operation, and what are the key current figures?
The R5F104GGAFB#V0 achieves ultra-low power via HALT (66 μA/MHz), STOP (0.60 μA with RTC + LVD active), and SNOOZE modes.
