Product details
Overview
R5F104MHGFA#30 from Renesas is a 48-pin LFQFP-packaged RL78/G14 16-bit microcontroller with 128 KB flash, 8 KB data flash, 16 KB RAM, 16–32 MHz operation, and ultra-low-power HALT/STOP/SNOOZE modes. It integrates 12-bit ADC (16 ch), UART/LIN (4 ch), I²C (10 ch), SPI (8 ch), RTC, and operates from 1.6–5.5 V for industrial motor control and sensor interface applications.
For engineers reviewing the R5F104MHGFA#30 datasheet, R5F104MHGFA#30 pinout, R5F104MHGFA#30 application, or R5F104MHGFA#30 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm pitch package, -40°C to +105°C industrial temperature grade (G), 128 KB code flash with self-programming, and integrated LIN-capable UARTs for automotive body electronics and industrial HMI systems.
Technical Context
The R5F104MHGFA#30 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (@32 MHz) to 30.5 µs (@32.768 kHz), plus multiply/divide/accumulate instructions and 1 MB address space. It features a high-accuracy ±1.0% on-chip oscillator (1–64 MHz selectable) and dual-clock domain architecture separating main and subsystem clocks.
Peripheral integration includes Event Link Controller (ELC) for hardware-triggered peripheral chaining, Data Transfer Controller (DTC) with block/chain transfer, and background operation (BGO) for concurrent code execution during data flash rewriting - enabling real-time firmware updates without CPU suspension.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104LGFB#30 | Same 48-pin LFQFP package, 96 KB flash, 8 KB data flash, 12 KB RAM, identical peripheral set and pinout | Lower flash/RAM capacity suits simpler control tasks (e.g., basic appliance timers) where 128 KB is unnecessary | Select when firmware size ≤96 KB and cost optimization is prioritized without sacrificing package or peripheral compatibility |
| R5F104PHGFA#30 | Same 48-pin LFQFP package, 128 KB flash, 8 KB data flash, 16 KB RAM, but rated for -40°C to +85°C (A grade) instead of +105°C (G grade) | Targeted at consumer-grade applications (e.g., white goods) where extended temperature range is not required | Choose for cost-sensitive commercial designs operating within 85°C ambient; verify thermal margin before substituting in industrial environments |
Compared with R5F104LGFB#30 and R5F104PHGFA#30, the R5F104MHGFA#30 uniquely delivers industrial-grade +105°C operation with full 128 KB flash headroom and identical pinout - making it optimal for thermally demanding motor drives and automotive body modules where reliability under sustained high temperature is non-negotiable.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F104MHGFA#30?
The R5F104MHGFA#30 operates up to 32 MHz with a typical active current of 66 μA/MHz at VDD = 3.0 V and TA = 25°C. Its ultra-low-power HALT mode achieves this efficiency while maintaining register retention and fast wake-up - critical for duty-cycled sensor applications where the R5F104MHGFA#30 spends >90% of time in low-power states.
Does the R5F104MHGFA#30 support LIN bus communication, and how is it implemented?
Yes, the R5F104MHGFA#30 supports LIN 2.2/SAE J2602 via its UART channels with built-in sync-break detection, checksum calculation, and automatic header response timing. No external transceiver is needed for basic LIN slave functionality - the R5F104MHGFA#30 drives the bus directly through configured UART pins, simplifying automotive sub-node design.
What is the flash memory endurance and data retention specification for the R5F104MHGFA#30?
The R5F104MHGFA#30 guarantees 10,000 write/erase cycles for code flash and 1,000,000 cycles for data flash (typical). Data retention is rated for 20 years at +85°C and indefinite at lower temperatures. These specs apply to the R5F104MHGFA#30's embedded flash - validated per JEDEC standards and documented in Renesas' RL78 Flash Memory Reliability Handbook.
How does the R5F104MHGFA#30 handle analog reference voltage for its ADC?
The R5F104MHGFA#30 provides an internal 1.45 V reference (AVREFP/AVREFM) usable as ADC reference, eliminating need for external precision references in most applications. It also supports external reference inputs and allows independent configuration of AVREFP (positive) and AVREFM (negative) pins - enabling ratiometric or differential measurements essential in the R5F104MHGFA#30's sensor interface role.
Is the R5F104MHGFA#30 pin-compatible with other RL78/G14 variants in the same 48-pin LFQFP package?
Yes, all RL78/G14 devices in the 48-pin LFQFP package (e.g., R5F104LGFB#30, R5F104PHGFA#30) share identical pinouts and electrical characteristics. The R5F104MHGFA#30 maintains full mechanical and signal-level compatibility - allowing drop-in replacement within the same footprint when upgrading flash/RAM or temperature grade, provided firmware is recompiled for target memory map.
