Product details
Overview
R5F104MGAFB#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 integrated 10-bit ADC (20-channel), RTC, and low-power STOP/HALT/SNOOZE modes - deployed in smart metering, industrial sensor nodes, and battery-powered HMI controllers.
For engineers reviewing the R5F104MGAFB#V0 datasheet, R5F104MGAFB#V0 pinout, R5F104MGAFB#V0 application, or R5F104MGAFB#V0 equivalent, key selection criteria include its 96 KB code flash with data flash shield window, 1.6–5.5 V operation, 66 μA/MHz active current, and support for LIN-bus UART and hardware event linking via ELC.
Technical Context
The R5F104MGAFB#V0 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), and includes multiply/divide/accumulate instructions. Its memory subsystem integrates 96 KB on-chip flash (1 KB block size), 12 KB RAM, and 8 KB data flash with background operation (BGO) and 1M-cycle rewrite endurance.
Peripheral integration includes 12-channel 16-bit Timer Array Unit (TAU), real-time clock with calendar/alarm, 20-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, dual UART/LIN interfaces, up to 10-channel I²C, and Event Link Controller (ELC) enabling direct peripheral-to-peripheral signal routing without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104MHAFB#V0 | Same 80-pin LFQFP package, but 128 KB flash + 16 KB RAM; identical peripheral set and pinout. | Required where larger firmware image size or extended data logging buffer is needed. | Select when future firmware growth headroom or additional RAM for protocol stacks (e.g., Modbus TCP) is essential. |
| R5F104LGAFB#V0 | 64-pin LFQFP, 0.5 mm pitch; 96 KB flash, 12 KB RAM, same core/peripherals but fewer I/O (64 vs. 80 pins). | Suitable for space-constrained designs where 16 fewer GPIOs and no P7x/KRx keypad interface are acceptable. | Choose for cost-optimized, compact industrial controls where full 80-pin I/O count is unnecessary. |
Compared with R5F104MHAFB#V0, the R5F104MGAFB#V0 trades flash/RAM headroom for identical footprint and cost efficiency; versus R5F104LGAFB#V0, it delivers 16 extra GPIOs and keypad scan capability at the expense of board area - enabling scalable design reuse across product tiers.

The R5F104MGAFB#V0 operates up to 32 MHz with a typical active current of 66 μA/MHz at VDD = 3.3 V and TA = 25°C. At full speed, this equates to ~2.1 mA total active current, verified in Renesas' R01DS0053EJ0340 datasheet Section 1.1.
Does the R5F104MGAFB#V0 support LIN bus communication, and which UART channel implements it?
Yes, the R5F104MGAFB#V0 supports LIN bus communication via UART channels 0, 1, or 2 - all include LIN-specific features like automatic sync-break detection and checksum generation per ISO 14229. Channel 2 (pins P13/P14) is commonly used for LIN due to dedicated TRDIOx signal routing.
What is the data flash endurance specification for the R5F104MGAFB#V0, and does it require special voltage conditions for rewriting?
The R5F104MGAFB#V0 specifies 1,000,000 write/erase cycles (typical) for its 8 KB data flash. Rewriting is supported across the full operating voltage range of VDD = 1.8 V to 5.5 V - no elevated voltage or external charge pump is required.
How many analog input channels does the R5F104MGAFB#V0 support, and what reference options are available for the ADC?
The R5F104MGAFB#V0 supports 20 analog input channels (ANI0–ANI19). The ADC accepts either external references via AVREFP/AVREFM pins or the internal 1.45 V reference - selectable per channel in ADCSR register, enabling mixed-signal designs with varying sensor types.
Is the R5F104MGAFB#V0 pin-compatible with other RL78/G14 variants in the same 80-pin LFQFP package?
Yes, all RL78/G14 80-pin LFQFP variants - including R5F104MGAFB#V0, R5F104MHAFB#V0, and R5F104MJAFB#V0 - share identical pinout, electrical characteristics, and mechanical footprint (PLQP0080KE-A), enabling drop-in replacement within the same memory/peripheral configuration tier.
