Product details
Overview
R5F100MGDFB#30 from Renesas is a 80-pin LFQFP-0.5mm-pitch, industrial-grade (−40°C to +105°C) RL78/G13 16-bit MCU with 128 KB flash, 8 KB data flash, 12 KB RAM, and integrated RTC/LVD. It delivers 41 DMIPS at 32 MHz, consumes 66 μA/MHz active and 0.57 μA in RTC+LVD-only mode, and supports UART, I²C, CSI, 16-bit timers, and 10-bit ADC across 62 analog input channels - deployed in battery-powered industrial sensors and motor control interfaces.
For engineers reviewing the R5F100MGDFB#30 datasheet, R5F100MGDFB#30 pinout, R5F100MGDFB#30 application, or R5F100MGDFB#30 equivalent, key selection criteria include its G-grade temperature rating, LFQFP-80 package with 0.5 mm pitch, on-chip debug support, self-programmable flash with boot swap, and BGO-capable data flash for concurrent execution and rewriting.
Technical Context
The R5F100MGDFB#30 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). Its memory subsystem includes 128 KB code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 12 KB SRAM - all accessible under single 1.6–5.5 V supply operation.
Peripheral integration includes dual DMA controllers (4-channel), 16-bit timer array (16 channels), real-time clock with calendar/alarm/correction, watchdog timer, 10-bit ADC (62 channels, internal 1.45 V reference), and multiple serial interfaces: up to 8 CSI, 4 UART/LIN, and 10 I²C/Simplified I²C channels - all configurable via dedicated SFRs and interrupt vectors.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100MGAFB#30 | Same 128 KB flash, 8 KB data flash, 12 KB RAM, but rated for −40°C to +85°C (D-grade); identical LFQFP-80 package and pinout. | Targeted at commercial/industrial ambient environments without extended temperature requirements. | Select when operating temperature does not exceed +85°C and cost optimization is prioritized over extended thermal qualification. |
| R5F101MGDFB#30 | Same package and pinout, but lacks data flash memory (0 KB); retains 128 KB code flash, 12 KB RAM, and identical peripheral set. | Suitable where firmware updates occur only during manufacturing or field service - no runtime parameter storage needed. | Choose when data logging, calibration storage, or field-upgradable configuration is unnecessary, reducing BOM cost and flash management complexity. |
