Renesas R5F100MGDFA#50

Overview

R5F100MGDFA#50 from Renesas is an RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating at up to 32 MHz (41 DMIPS), featuring ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), integrated 10-bit ADC (26 channels), real-time clock, and multiple serial interfaces (UART, I²C, CSI) in an 80-pin LQFP package for industrial control and sensor node applications.

For engineers reviewing the R5F100MGDFA#50 datasheet, R5F100MGDFA#50 pinout, R5F100MGDFA#50 application, or R5F100MGDFA#50 equivalent, key selection considerations include its industrial-grade temperature range (–40°C to +85°C), on-chip debug support, self-programmable flash with boot swap, background data flash rewriting, and hardware multiplier/divider for deterministic control loop execution.

Technical Context

The R5F100MGDFA#50 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). It integrates a 12-bit interval timer, calendar-based real-time clock with alarm and correction, and watchdog timer with dedicated low-speed oscillator.

Power management includes HALT, STOP, and SNOOZE modes, on-chip POR and 14-level LVD, and DMA controller with 4 channels enabling 2-clock transfers between SFR and RAM. The high-accuracy ±1.0% on-chip oscillator supports 32/24/16/12/8/6/4/3/2/1 MHz selections across 1.8–5.5 V supply.

FAQ

What is the maximum operating frequency and corresponding performance of the R5F100MGDFA#50?

The R5F100MGDFA#50 operates at up to 32 MHz with a peak performance of 41 DMIPS. Its RL78 CPU core achieves this through a 3-stage pipeline and high-speed on-chip oscillator with ±1.0% accuracy across 1.8–5.5 V and –40°C to +85°C. This enables deterministic execution of real-time control loops and communication stacks without external clock components.

Does the R5F100MGDFA#50 support in-system programming and secure firmware updates?

Yes, the R5F100MGDFA#50 supports full in-system programming via its on-chip debug interface and includes flash shield window and boot swap functions for secure firmware updates. These features allow safe field upgrades by protecting critical bootloader sections while enabling verified application code replacement - all without requiring external programmers.

How does the R5F100MGDFA#50 manage power in battery-operated applications?

The R5F100MGDFA#50 delivers industry-leading low-power operation: 66 μA/MHz active current, 0.57 μA in STOP mode with RTC and LVD enabled, and configurable HALT/SNOOZE modes. Its independent subsystem clock (32.768 kHz) ensures RTC accuracy during deep sleep, making it ideal for multi-year battery life in wireless sensors and portable equipment.

What analog and timing peripherals are integrated into the R5F100MGDFA#50?

The R5F100MGDFA#50 integrates a 10-bit ADC with 26 input channels, internal 1.45 V reference, and temperature sensor; a calendar-based real-time clock with alarm and correction; 16× 16-bit timers; a 12-bit interval timer; and a watchdog timer with dedicated low-speed oscillator. These enable precise measurement, time-stamped event logging, and fail-safe system supervision.

Is the R5F100MGDFA#50 pin-compatible with other RL78/G13 variants in the same package?

Yes, all RL78/G13 devices in the 80-pin LQFP package - including R5F100MGDFA#50, R5F100LGDFA#50, and R5F101MGDFA#50 - share identical pinouts and electrical characteristics. This allows direct substitution within the same footprint for memory scaling or feature optimization without PCB redesign.
