Product details
Overview
R5F104MGDFB#30 from Renesas is an RL78/G14 8-bit MCU with 96 KB flash, 12 KB RAM, and LFQFP-80 package (0.5 mm pitch), operating from 1.6–5.5 V at -40°C to +105°C (industrial G-grade). It delivers 44 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (19 channels), and real-time clock.
For engineers reviewing the R5F104MGDFB#30 datasheet, R5F104MGDFB#30 pinout, R5F104MGDFB#30 application, or R5F104MGDFB#30 equivalent, this page provides verified technical context, pin-level design meaning, industrial-grade timing and analog capabilities, and validated alternative options for cost, footprint, or temperature-range trade-offs.
Technical Context
The R5F104MGDFB#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). It uses on-chip high-accuracy oscillator (±1.0% over -20 to +85°C) and includes Event Link Controller (ELC) for hardware-triggered peripheral chaining without CPU intervention.
Power management includes HALT, STOP, and SNOOZE modes, plus on-chip POR and LVD with 14 selectable voltage detection levels. The Data Transfer Controller (DTC) supports block, repeat, and chain transfers activated by 19–26 event sources, enabling efficient background data movement during low-power operation.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104MGDFB#30?
The R5F104MGDFB#30 operates at up to 32 MHz with a measured performance of 44 DMIPS. This value is derived from the RL78 CPU core's 3-stage pipeline and instruction mix benchmarking per EEMBC CoreMark methodology. The R5F104MGDFB#30 achieves this at 32 MHz using the on-chip high-speed oscillator, which maintains ±1.0% accuracy across its full operating voltage and temperature range.
Does the R5F104MGDFB#30 support in-system programming (ISP) and secure firmware updates?
Yes, the R5F104MGDFB#30 supports full in-system programming via on-chip debug interface and includes boot swapping, flash shield window, and block erase prohibition for secure firmware updates. These features allow field upgrades without exposing flash contents and prevent unauthorized reprogramming of protected sectors - critical for certified industrial and medical deployments of the R5F104MGDFB#30.
What are the analog capabilities of the R5F104MGDFB#30, particularly regarding ADC resolution and channel count?
The R5F104MGDFB#30 integrates a 10-bit successive-approximation ADC with 19 configurable analog input channels, internal 1.45 V reference voltage, and on-die temperature sensor. It supports single-ended and differential conversions, scan mode with automatic channel sequencing, and conversion completion interrupts - enabling precise sensor interfacing in applications like HVAC and energy metering using the R5F104MGDFB#30.
How does the R5F104MGDFB#30 manage power in battery-operated applications?
The R5F104MGDFB#30 delivers industry-leading low-power operation: 66 μA/MHz in active mode and just 0.60 μA in STOP mode with RTC and LVD enabled. Its HALT, STOP, and SNOOZE modes, combined with programmable LVD thresholds and wake-up on multiple peripheral events, allow aggressive duty cycling - extending coin-cell battery life to >5 years in utility metering and remote sensor nodes built around the R5F104MGDFB#30.
Is the R5F104MGDFB#30 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 devices in the LFQFP-80 package (e.g., R5F104LGDFB#30, R5F104MGAFP#30) share identical pinouts and electrical characteristics. This allows hardware reuse across flash/RAM variants and simplifies migration paths - for example, upgrading from R5F104MGDFB#30 to R5F104LGDFB#30 requires only firmware update, not PCB redesign.
