Product details
Overview
R5F104GDGFB#10 from Renesas is a 48-pin LFQFP, 0.5 mm pitch, industrial-grade (−40°C to +105°C) 16-bit RL78/G14 microcontroller with 128 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 features ultra-low-power modes (66 μA/MHz active, 0.60 μA RTC+LVD). It targets battery-powered industrial sensors and motor control interfaces.
For engineers reviewing the R5F104GDGFB#10 datasheet, R5F104GDGFB#10 pinout, R5F104GDGFB#10 application, or R5F104GDGFB#10 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm package, 128 KB/12 KB/8 KB memory configuration, integrated RTC+LVD low-power retention, and support for UART/LIN, I²C, and 16-bit TAU timers in harsh-temperature environments.
Technical Context
The R5F104GDGFB#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode). It integrates a Data Transfer Controller (DTC) with chain transfer and an Event Link Controller (ELC) enabling direct peripheral-to-peripheral event routing without CPU intervention.
Its analog subsystem includes an 8/10-bit ADC with up to 20 channels, internal 1.45 V reference, and temperature sensor; an 8-bit DAC with two outputs; and dual comparators with window/high-speed/low-speed modes. The serial interface set comprises up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, and 8 CSI (SPI-compatible) channels - all configurable via peripheral I/O redirection registers.

FAQ
What is the operating temperature range of the R5F104GDGFB#10?
The R5F104GDGFB#10 is rated for industrial operation from −40°C to +105°C (G-grade), validated per Renesas specification R01DS0053EJ0370. This makes it suitable for deployment in high-ambient environments such as motor drives, power supplies, and outdoor sensor enclosures where extended thermal resilience is required. The device maintains full functionality-including RTC, ADC, and LVD-across this entire range.
Does the R5F104GDGFB#10 support LIN bus communication?
Yes, the R5F104GDGFB#10 supports LIN bus communication through its UART peripherals. Specifically, UART channels (e.g., UART0 on P50/P51 or UART2 on P13/P14) can be configured for LIN 2.1/2.2 protocol operation, including break detection, sync field handling, and checksum calculation in hardware. The RL78/G14's built-in LIN timing accuracy meets ISO 17987 requirements when using the high-accuracy on-chip oscillator.
How much data flash does the R5F104GDGFB#10 include, and what is its endurance?
The R5F104GDGFB#10 includes 8 KB of data flash memory, organized in 1 KB blocks. Its specified endurance is 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. Background operation (BGO) allows CPU code execution from program flash while data flash is being rewritten, enabling seamless firmware parameter updates without halting real-time tasks.
What debug interface does the R5F104GDGFB#10 use, and which pins are required?
The R5F104GDGFB#10 uses the Renesas Trace Debugger (TRDIO) interface, a 4-wire debug protocol compatible with E2 emulator Lite and E2 studio. Required pins are P10 (TRDIOD1), P11 (TRDIOC1), P12 (TRDIOB1), and P17 (TRDIOA0/TRDCLK), plus RESET and VDD. No external debug probe voltage translation is needed, as TRDIO operates at core VDD levels (1.6–5.5 V).
Is the R5F104GDGFB#10 pin-compatible with other RL78/G14 variants in 48-pin LFQFP?
Yes, the R5F104GDGFB#10 is fully pin-compatible with all RL78/G14 devices in the 48-pin LFQFP-0.5 mm package (e.g., R5F104GAGFB#10, R5F104GHGFB#10), sharing identical pin functions, electrical characteristics, and thermal pad layout. Memory and peripheral differences (e.g., flash size, ADC channels) do not affect pin behavior or PCB footprint - enabling drop-in replacement within the same package family.
