Product details
Overview
R5F101MGAFA#10 from Renesas is an RL78/G13 80-pin LQFP-0.65mm microcontroller with 64 KB flash, 4 KB data flash, 4 KB RAM, 16-bit CPU core, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode) for industrial control, sensor nodes, and battery-powered HMI systems.
For engineers reviewing the R5F101MGAFA#10 datasheet, R5F101MGAFA#10 pinout, R5F101MGAFA#10 application, or R5F101MGAFA#10 equivalent, key selection criteria include its 80-pin LQFP package, absence of on-chip data flash (R5F101x series), -40°C to +85°C industrial temperature grade ('D' suffix), and support for 16-channel 10-bit ADC, real-time clock, and LIN-capable UART interfaces.
Technical Context
The R5F101MGAFA#10 implements the RL78 CISC CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, calendar-based real-time clock with alarm and correction, and watchdog timer with dedicated low-speed oscillator.
Its peripheral set includes up to 16 channels of 10-bit A/D converter with internal 1.45 V reference and temperature sensor, 8–16 channels of 16-bit timer, 2–4 channel DMA controller, and serial interfaces: 2–4 UART/LIN, 2–8 CSI (SPI-compatible), and 3–10 I²C/Simplified I²C channels - all configurable without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100MGAFA#10 | Includes 8 KB data flash; same 64 KB code flash, 8 KB RAM, identical package and pinout | Required where field firmware updates or parameter storage exceed 4 KB SRAM capacity | Select when non-volatile parameter logging or dual-bank firmware updates are needed |
| R5F101MGAFB#30 | Same core and memory, but in 80-pin LFQFP (0.5 mm pitch, 12 × 12 mm) - smaller footprint, tighter layout | Suitable for space-constrained PCBs where 0.65 mm pitch LQFP is impractical | Choose for higher-density designs; verify soldering process compatibility with 0.5 mm pitch |
Compared with R5F100MGAFA#10, the R5F101MGAFA#10 trades data flash capacity for lower cost and reduced die size - ideal for fixed-function applications. Against R5F101MGAFB#30, it offers easier hand-soldering and legacy board compatibility at the expense of board area efficiency.

FAQ
What is the flash memory configuration of the R5F101MGAFA#10?
The R5F101MGAFA#10 contains 64 KB of on-chip code flash memory with 1 KB erase blocks and no integrated data flash - consistent with the R5F101x series designation. This configuration targets applications where parameters are stored in external EEPROM or managed in volatile RAM with backup power.
Does the R5F101MGAFA#10 support LIN bus communication?
Yes, the R5F101MGAFA#10 supports LIN 2.2 communication through its UART peripheral, which includes hardware support for LIN break detection, sync field handling, and checksum generation - enabling direct integration into automotive body electronics and industrial sub-networks.
What is the operating temperature range for the R5F101MGAFA#10?
The R5F101MGAFA#10 is rated for industrial operation from –40°C to +85°C, indicated by the 'D' suffix in its part number family. It does not support the extended –40°C to +105°C range ('G' grade) offered by some RL78/G13 variants.
Can the R5F101MGAFA#10 operate from a single 1.8 V supply?
Yes, the R5F101MGAFA#10 supports 1.6 V to 5.5 V single-supply operation. At 1.8 V, it delivers reduced maximum frequency (typically ≤ 8 MHz) but retains full peripheral functionality including ADC, RTC, and UART - ideal for energy-harvesting or low-voltage battery systems.
How many analog input channels does the R5F101MGAFA#10 provide?
The R5F101MGAFA#10 provides 16 analog input channels for its 10-bit A/D converter, with selectable references including VDD, AVREFP/AVREFM, and internal 1.45 V. The temperature sensor and internal reference are accessible only in HS (high-speed main) mode per the datasheet specification.
