Product details
Overview
R5F104MGGFB#V0 from Renesas is a 80-pin LFQFP, 0.5 mm pitch, industrial-grade (−40°C to +105°C) RL78/G14 16-bit MCU with 96 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 consumption (66 μA/MHz active, 0.60 μA in RTC+LVD mode), making it suitable for battery-powered industrial sensors and motor control interfaces.
For engineers reviewing the R5F104MGGFB#V0 datasheet, R5F104MGGFB#V0 pinout, R5F104MGGFB#V0 application, or R5F104MGGFB#V0 equivalent, key selection considerations include its 80-pin LFQFP-0.5 mm package, integrated 12-bit RTC with calendar/alarm, dual UART/LIN support, 10-channel 10-bit ADC, and hardware DTC/ELC for deterministic peripheral event handling without CPU intervention.
Technical Context
The R5F104MGGFB#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs @ 32 MHz to 30.5 µs @ 32.768 kHz). It integrates a Data Transfer Controller (DTC) supporting normal, repeat, and block transfer modes triggered by 19–26 event sources via the Event Link Controller (ELC).
Its analog subsystem includes a 10-bit A/D converter with up to 20 input channels, internal 1.45 V reference, and temperature sensor; an 8-bit D/A converter with two output channels; and up to two comparators with selectable internal/external reference and window mode operation.

The R5F104MGGFB#V0 achieves a maximum operating frequency of 32 MHz, delivering 44 DMIPS (Dhrystone MIPS) performance. This benchmark reflects its real-time computational capability for control loops and communication stack processing under typical operating conditions with the RL78 CPU core's 3-stage pipeline and optimized instruction set.
Does the R5F104MGGFB#V0 support LIN bus communication, and how is it implemented?
Yes, the R5F104MGGFB#V0 supports LIN bus communication through its UART peripherals, which include LIN-specific features such as automatic sync field detection, checksum calculation (classic and enhanced), and break signal generation. UART channels can be configured in LIN mode via the serial control registers, enabling direct compliance with LIN 2.2A specifications without external transceivers beyond the physical layer.
How does the R5F104MGGFB#V0 manage ultra-low-power operation, and what is its lowest current consumption mode?
The R5F104MGGFB#V0 achieves ultra-low-power operation via multiple low-power modes: HALT (CPU stopped, peripherals active), STOP (all clocks halted except RTC/LVD), and SNOOZE (selected peripherals active while CPU sleeps). Its lowest current consumption is 0.60 μA in STOP mode with only the real-time clock and low-voltage detector enabled - verified at VDD = 1.8–5.5 V and TA = −40°C to +105°C.
What are the data flash endurance and rewrite voltage requirements for the R5F104MGGFB#V0?
The R5F104MGGFB#V0 includes 8 KB of data flash memory rated for 1,000,000 rewrite cycles (typical) and supports rewrites across the full operating supply range of VDD = 1.8 V to 5.5 V. Background operation (BGO) allows CPU code execution from main flash memory during data flash erase/write sequences, enabling seamless firmware parameter updates without system interruption.
Is the R5F104MGGFB#V0 pin-compatible with other RL78/G14 variants in the same 80-pin LFQFP package?
Yes, the R5F104MGGFB#V0 shares identical pinout, electrical characteristics, and package dimensions (80-pin LFQFP, 12 × 12 mm, 0.5 mm pitch) with all other RL78/G14 family members in the same package variant, including R5F104MHGFB#V0 and R5F104LEGFB#V0. This enables direct substitution within the same hardware design when memory or feature requirements change.
