Product details
Overview
R5F10MMGDFB#50 from Renesas Electronics is an RL78/I1B-series 16-bit single-chip microcontroller in an 80-pin LQFP package, featuring 256 KB flash memory, 20 KB RAM, and integrated LCD controller supporting up to 8 × 40 segments. It operates at up to 32 MHz with 1.6 V to 5.5 V supply range and includes hardware real-time clock, 12-bit ADC (24 channels), and 16-bit timer arrays for motor control and industrial sensing applications.
For engineers reviewing the R5F10MMGDFB#50 datasheet, R5F10MMGDFB#50 pinout, R5F10MMGDFB#50 application, or R5F10MMGDFB#50 equivalent, key selection criteria include its 80-pin LQFP-0.5mm pitch package, on-chip debug interface (FINE), 256 KB flash with data flash functionality, and support for low-power modes down to 0.52 µA in HALT mode - critical for battery-powered metering and portable HMI designs.
Technical Context
The R5F10MMGDFB#50 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and 16-bit ALU. It integrates a 12-bit successive-approximation ADC with sample-and-hold, programmable gain amplifier (PGA) input options, and hardware multiplier/divider for efficient signal processing.
Its peripheral set includes three 16-bit timer arrays (TAU) with complementary PWM output, a 16-bit real-time clock (RTC) with calendar function and crystal oscillator support (32.768 kHz), and an 8-channel serial interface (UART, CSI, I²C) with automatic baud rate detection and clock synchronous operation.

FAQ
What is the maximum operating frequency of the R5F10MMGDFB#50?
The R5F10MMGDFB#50 supports a maximum CPU clock frequency of 32 MHz when using the high-speed on-chip oscillator or an external crystal up to 20 MHz with PLL multiplication. This frequency enables real-time execution of control algorithms and communication stacks while maintaining low power consumption through dynamic clock gating.
Does the R5F10MMGDFB#50 include an integrated real-time clock (RTC)?
Yes, the R5F10MMGDFB#50 includes a hardware RTC with calendar function (year/month/day/hour/minute/second), alarm interrupt, and periodic interrupt capability. It operates independently using a 32.768 kHz crystal connected to XT1/XT2 pins, retaining timekeeping in STOP and HALT modes with minimal current draw.
What LCD configuration does the R5F10MMGDFB#50 support?
The R5F10MMGDFB#50 supports up to 8 commons × 40 segments (320 total segments) via its integrated LCD controller. It provides internal bias voltage generation, software-configurable duty cycle (1/2, 1/3, 1/4, 1/6, 1/8), and frame frequency control - eliminating need for external LCD driver ICs in compact display applications.
How much data flash memory is available on the R5F10MMGDFB#50?
The R5F10MMGDFB#50 includes 1 KB of dedicated data flash memory within its 256 KB main flash array. This area supports separate erase/write operations with 100,000 endurance cycles and is used for storing calibration data, device-specific parameters, or firmware update flags without affecting program code integrity.
What debug interface does the R5F10MMGDFB#50 use?
The R5F10MMGDFB#50 uses the FINE (Fast In-circuit Non-intrusive Emulator) debug interface, which requires only a single pin (typically P10 or dedicated FINE pin) for programming and debugging. It supports full breakpoint, watchpoint, and trace capabilities without halting CPU execution during real-time monitoring.
