Product details
Overview
R5F104GJGFB#10 from Renesas is a 48-pin LFQFP, 128 KB flash, 12 KB RAM RL78/G14 16-bit microcontroller operating from 1.6–5.5 V, delivering 44 DMIPS at 32 MHz with ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD mode), used in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F104GJGFB#10 datasheet, R5F104GJGFB#10 pinout, R5F104GJGFB#10 application, or R5F104GJGFB#10 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G), 48-pin 0.5 mm pitch LFQFP package, integrated 10-bit 20-channel ADC, dual UART/LIN support, and hardware DTC/ELC for deterministic peripheral event handling.
Technical Context
The R5F104GJGFB#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock), and includes multiply/divide/accumulate instructions with 1 MB address space.
It integrates a Data Transfer Controller (DTC) with normal/repeat/block transfer modes activated by 19–26 event sources via the Event Link Controller (ELC), enabling zero-CPU-overhead peripheral-to-peripheral data movement and synchronized timer-triggered ADC sampling or UART transmission.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F104GJGFB#10?
The R5F104GJGFB#10 operates at up to 32 MHz using its high-speed on-chip oscillator, achieving 44 DMIPS (Dhrystone MIPS). This performance level supports real-time control loops with sub-10 µs execution time for typical motor control or sensor fusion algorithms, verified per Renesas R01DS0053EJ0370 datasheet Section 1.1.
Does the R5F104GJGFB#10 support hardware debugging and trace capabilities?
Yes, the R5F104GJGFB#10 supports on-chip debug via SWD/JTAG using dedicated pins (TRJO0, TRJIO0, TRDIOA0–D1), and includes trace output functionality through TRDIOx pins linked to the ELC. It also features a hardware breakpoint unit and real-time variable watch capability, all documented in the RL78/G14 User's Manual (R01UH0044EJ0300).
What are the supported serial communication interfaces on the R5F104GJGFB#10?
The R5F104GJGFB#10 integrates 3 UART/LIN channels, 4–10 I²C channels (configurable per variant), and 3–8 CSI channels (SPI-compatible). All UART channels support LIN 2.2 physical layer compliance, and I²C includes fast-mode (400 kbps) and standard-mode (100 kbps) operation - confirmed in Section 1.1 "Serial Interfaces" of R01DS0053EJ0370.
How does the R5F104GJGFB#10 achieve ultra-low power consumption in STOP mode?
The R5F104GJGFB#10 achieves 0.60 µA STOP mode current by disabling the CPU, flash, and most peripherals while retaining power to the RTC, LVD, and RAM retention circuitry. The internal LDO remains active only for these blocks, and the REGC capacitor stabilizes the regulated voltage - specified under "Ultra-Low Power Consumption Technology" in R01DS0053EJ0370 Rev. 3.70.
Is the R5F104GJGFB#10 pin-compatible with other RL78/G14 variants in the 48-pin LFQFP package?
Yes, all RL78/G14 devices in the 48-pin LFQFP package (FB suffix) share identical pinouts and electrical characteristics, including R5F104GJGFB#10, R5F104GHGFB#10, and R5F104GKGFB#10. Pin compatibility is guaranteed per Renesas Package Outline Drawing PLQP0048KF-A and confirmed in Table 1-1 of R01DS0053EJ0370.
