Product details
Overview
R5F101MGAFB#30 from Renesas is a 32-bit RL78/G13 microcontroller with no data flash, 96 KB code flash, 8 KB RAM, and LFQFP-80 (0.5 mm pitch) package. It operates from 1.6–5.5 V, achieves 41 DMIPS at 32 MHz, and supports ultra-low-power modes including STOP (0.57 μA) and HALT. It targets battery-powered industrial sensors and smart metering interfaces requiring RTC, ADC, and multiple serial peripherals.
For engineers reviewing the R5F101MGAFB#30 datasheet, R5F101MGAFB#30 pinout, R5F101MGAFB#30 application, or R5F101MGAFB#30 equivalent, key selection criteria include its 80-pin LFQFP footprint, absence of on-chip data flash, industrial-grade temperature range (−40°C to +105°C), and integrated 10-bit 26-channel ADC with internal temperature sensor.
Technical Context
The R5F101MGAFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates a high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz), real-time clock with calendar/alarm, and hardware multiplier/divider for efficient signal processing.
Peripherals include up to 16 channels of 16-bit timer, 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN interfaces, 2–8 CSI (SPI-compatible) channels, and DMA controller with 4 channels supporting background data flash operations - though this variant excludes data flash memory entirely.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F101MGAFB#30?
The R5F101MGAFB#30 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under these conditions, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation. This frequency agility allows the R5F101MGAFB#30 to balance responsiveness and energy use across diverse workload phases.
Does the R5F101MGAFB#30 include data flash memory?
No, the R5F101MGAFB#30 does not include data flash memory. As indicated by the "101" in its part number (per Renesas RL78/G13 naming convention), this variant provides 96 KB of code flash and 8 KB of RAM only. Applications requiring nonvolatile parameter storage must implement external EEPROM or utilize code flash sectors with wear-leveling software - unlike the R5F100x series which integrates 4–8 KB of dedicated data flash.
What temperature grade does the R5F101MGAFB#30 support?
The R5F101MGAFB#30 is rated for industrial operation from −40°C to +105°C, denoted by the "G" suffix in its part number. This extended range ensures reliable functionality in demanding environments such as factory automation, outdoor metering, and HVAC systems where ambient temperatures exceed standard commercial limits.
Which communication interfaces are available on the R5F101MGAFB#30?
The R5F101MGAFB#30 integrates multiple serial interfaces: up to 4 UART/LIN channels (with LIN physical layer support), 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels. These are mapped across its 80-pin LFQFP package with flexible pin multiplexing, enabling concurrent connectivity to displays, sensors, transceivers, and debug tools without external logic.
How does the R5F101MGAFB#30 achieve ultra-low power consumption?
The R5F101MGAFB#30 achieves ultra-low power through multiple hardware features: STOP mode draws just 0.57 μA while retaining RTC and LVD functionality; HALT mode consumes 66 μA/MHz; and its 1.6–5.5 V wide supply range eliminates need for intermediate regulators. Combined with configurable peripheral clocks and event-driven wake-up, the R5F101MGAFB#30 sustains multi-year battery life in duty-cycled applications.
