Product details
Overview
R5F104GDAFB#30 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 supports ultra-low-power modes including 0.60 μA STOP mode with RTC and LVD active - ideal for battery-powered industrial sensors and motor control interfaces.
For engineers reviewing the R5F104GDAFB#30 datasheet, R5F104GDAFB#30 pinout, R5F104GDAFB#30 application, or R5F104GDAFB#30 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm package, integrated 10-bit 20-channel ADC, dual UART/LIN support, and hardware-based Event Link Controller (ELC) for deterministic peripheral triggering without CPU intervention.
Technical Context
The R5F104GDAFB#30 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock). It integrates a Data Transfer Controller (DTC) with chain transfer capability and an Event Link Controller (ELC) that routes up to 26 event signals directly to peripherals - enabling low-latency, CPU-free peripheral coordination.
Its analog subsystem includes a 10-bit ADC with internal 1.45 V reference and temperature sensor, dual 8-bit DAC channels (0–VDD output), and two comparators with window/high-speed/low-speed modes. Power management features include on-chip POR, 14-level LVD with interrupt/reset options, and multiple low-power modes (HALT, STOP, SNOOZE) optimized for duty-cycled operation.
Key Specifications

Does the R5F104GDAFB#30 support LIN bus communication?
Yes, the R5F104GDAFB#30 supports LIN bus communication via its UART peripherals - specifically, UART0, UART1, and UART2 all include LIN break detection and sync field generation per LIN 2.2A specification. The hardware LIN mode reduces CPU load during frame transmission and improves timing accuracy.
What debug interface does the R5F104GDAFB#30 use?
The R5F104GDAFB#30 uses Renesas' on-chip debug interface accessible via the TOOL0 (P40) and TOOLRxD/TOOLTxD (P50/P51) pins. It supports full JTAG-style debugging, flash programming, and real-time trace through compatible debuggers such as E2 studio with E2 Lite or E2 emulator.
Can the R5F104GDAFB#30 operate from a single 1.8 V supply?
Yes, the R5F104GDAFB#30 operates from 1.6 V to 5.5 V, fully supporting 1.8 V single-supply operation. At 1.8 V, it achieves up to 16 MHz maximum frequency and maintains full functionality of ADC (with internal 1.45 V reference), RTC, and low-power modes - enabling compatibility with 1.8 V sensor ecosystems.
How many I²C interfaces does the R5F104GDAFB#30 include?
The R5F104GDAFB#30 includes four I²C interfaces (IICA0–IICA3), each supporting standard-mode (100 kbps) and fast-mode (400 kbps) operation. Two channels (IICA0/IICA1) can be configured as simplified I²C with reduced pin count, while all support multi-master arbitration and 7-/10-bit addressing.
