Product details
Overview
R5F104GAGFB#30 from Renesas is a 48-pin LFQFP-packaged RL78/G14 16-bit microcontroller with 128 KB flash, 12 KB RAM, and industrial-grade operation up to +105°C. It delivers 44 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.60 μA in RTC+LVD mode), and integrates 10-bit ADC (16 channels), UART/SPI/I²C interfaces, and real-time clock - deployed in motor control and sensor-based industrial HMI systems.
For engineers reviewing the R5F104GAGFB#30 datasheet, R5F104GAGFB#30 pinout, R5F104GAGFB#30 application, or R5F104GAGFB#30 equivalent, key selection criteria include its G-grade temperature rating (−40°C to +105°C), LFQFP-48 0.5 mm pitch package, 128 KB code flash with data flash shield, and support for background data flash rewriting (BGO) without CPU stall.
Technical Context
The R5F104GAGFB#30 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz low-power mode). It includes on-chip debug, self-programming with boot swapping, and flash shield window protection.
Peripheral integration includes Timer Array Unit (TAU) with 8 channels, 1-channel real-time clock with calendar and alarm, 1-channel watchdog timer, and Event Link Controller (ELC) enabling direct peripheral-to-peripheral event triggering without CPU intervention - reducing latency and power in deterministic control loops.

FAQ
What is the maximum operating frequency and corresponding DMIPS performance of the R5F104GAGFB#30?
The R5F104GAGFB#30 operates at up to 32 MHz with an RL78 CPU core delivering 44 DMIPS. This performance is achieved using the high-speed on-chip oscillator (±1.0% accuracy) or external crystal. The core's 3-stage pipeline and optimized instruction set enable deterministic real-time execution critical for motor control and sensor sampling loops in the R5F104GAGFB#30.
Does the R5F104GAGFB#30 support in-system programming and debug interfaces?
Yes, the R5F104GAGFB#30 supports single-wire debug (SWD) via the TOOL0 pin (P40) and optional TRJIO0/TRJO0 pins. It includes on-chip debug circuitry enabling full read/write/erase access, breakpoint setting, and real-time variable monitoring. Self-programming with boot swapping is supported, allowing safe firmware updates without external programmers - a key capability built into the R5F104GAGFB#30 architecture.
What are the flash memory configuration and security features of the R5F104GAGFB#30?
The R5F104GAGFB#30 contains 128 KB of code flash organized in 1 KB blocks, with programmable block erase prohibition and flash shield window for IP protection. Data flash is 8 KB with background operation (BGO) support. Security features include flash lock bits, prohibition of block erase/rewrite, and boot swapping with validation - all implemented in hardware to prevent unauthorized access or tampering in the R5F104GAGFB#30.
How does the R5F104GAGFB#30 achieve ultra-low power consumption in STOP mode?
The R5F104GAGFB#30 achieves 0.60 μA STOP mode current by powering down the CPU, flash, and most peripherals while retaining RTC operation, LVD monitoring, and RAM contents. The internal low-voltage regulator remains active only for these essential circuits. Wake-up sources include RTC alarm, LVD interrupt, or external pins - enabling precise, energy-efficient duty-cycled operation in battery-powered applications using the R5F104GAGFB#30.
What peripheral interfaces are available on the R5F104GAGFB#30 for industrial connectivity?
The R5F104GAGFB#30 provides three UART channels (one with LIN support), up to ten I²C/simplified I²C channels, and three to eight CSI (SPI-compatible) channels. It also includes a 16-bit Timer Array Unit (TAU) with 8 channels, real-time clock with calendar, and Event Link Controller (ELC) for hardware-triggered peripheral chaining - collectively enabling robust serial communication, precise timing, and deterministic event handling in industrial systems built around the R5F104GAGFB#30.
