Product details
Overview
R5F104MGGFA#30 from Renesas is a 32-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and 80-pin LFQFP (0.5 mm pitch) package, operating from 1.6–5.5 V at -40 to +105°C. It delivers 44 DMIPS at 32 MHz, integrates 10-bit ADC (20 channels), RTC, UART/I²C/CSI interfaces, and ultra-low-power modes (0.60 μA in STOP with RTC+LVD).
For engineers reviewing the R5F104MGGFA#30 datasheet, R5F104MGGFA#30 pinout, R5F104MGGFA#30 application, or R5F104MGGFA#30 equivalent, key selection criteria include industrial-temperature operation, integrated data flash (8 KB), hardware event linking (ELC), and support for background data flash rewriting (BGO) without CPU stall.
Technical Context
The R5F104MGGFA#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 subsystem clock). It features a Data Transfer Controller (DTC) with chain transfer and an Event Link Controller (ELC) enabling direct peripheral-to-peripheral signal routing without CPU intervention.
Its memory subsystem includes 96 KB code flash (1 KB block size), 8 KB data flash with 1,000,000 write cycles, and 12 KB on-chip RAM. Power management includes HALT, STOP, and SNOOZE modes, plus on-chip LVD with 14 selectable voltage thresholds and POR circuitry.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F104MGGFA#30?
The R5F104MGGFA#30 operates at up to 32 MHz, delivering 44 DMIPS of processing performance. Its RL78 CPU core supports variable instruction timing - as fast as 0.03125 µs per instruction at full speed, or as slow as 30.5 µs at 32.768 kHz for ultra-low-power RTC operation. This dual-speed capability allows dynamic power/performance scaling within a single device.
Does the R5F104MGGFA#30 support in-system programming and secure firmware updates?
Yes, the R5F104MGGFA#30 supports full in-system programming via its on-chip debug interface and boot swapping functionality. It includes flash shield window protection to prevent unauthorized access to code memory, and block-level erase/write prohibition for secure bootloader regions. Firmware updates can be performed over UART or CAN using Renesas-provided flash programming libraries.
How does the R5F104MGGFA#30 handle analog sensing in noisy industrial environments?
The R5F104MGGFA#30 integrates a 10-bit SAR ADC with 20 input channels, internal 1.45 V reference voltage, and dedicated AVREFP/AVREFM pins for precision analog domain separation. It supports programmable sampling time, hardware averaging (up to 32 samples), and conversion triggers linked via ELC - enabling synchronous sampling with motor PWM or external sensors while rejecting noise through digital filtering.
What packaging and thermal characteristics define the R5F104MGGFA#30?
The R5F104MGGFA#30 uses an 80-pin LFQFP package (12 × 12 mm, 0.5 mm pitch) with an exposed thermal pad that must be connected to VSS for optimal thermal dissipation. Its θJA is 36°C/W under standard JEDEC 2-layer board conditions. The package supports industrial reflow profiles and is qualified for moisture sensitivity level 3 (MSL3).
Can the R5F104MGGFA#30 operate reliably across the full -40°C to +105°C range without derating?
Yes, the R5F104MGGFA#30 is G-grade qualified for continuous operation from -40°C to +105°C ambient temperature. All specifications - including flash endurance (1,000,000 data flash writes), ADC accuracy, oscillator stability (±1.0% over full range), and supply current (0.60 μA STOP mode) - are guaranteed across this range. No derating of voltage, frequency, or timing parameters is required.
