Product details
Overview
R5F101MGAFA#V0 from Renesas is a 80-pin LQFP-0.65mm microcontroller in the RL78/G13 family, featuring 128 KB flash memory, 8 KB data flash, 12 KB RAM, and operation from 1.6 V to 5.5 V. It delivers 41 DMIPS at 32 MHz, supports ultra-low-power modes (0.57 μA RTC+LVD), and integrates 16-bit timers, 10-bit ADC (26 channels), UART, I²C, CSI, and real-time clock - deployed in battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F101MGAFA#V0 datasheet, R5F101MGAFA#V0 pinout, R5F101MGAFA#V0 application, or R5F101MGAFA#V0 equivalent, key selection criteria include its 80-pin LQFP-0.65mm package, absence of on-chip data flash (confirmed by "101" suffix), -40°C to +85°C industrial temperature grade ('A' suffix), and compatibility with Renesas CS+ and e² studio toolchains for low-power firmware development.
Technical Context
The R5F101MGAFA#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It includes a 12-bit interval timer, calendar-capable real-time clock with alarm and correction, and watchdog timer driven by dedicated low-speed oscillator.
Its peripheral set targets embedded control: 16-bit timer array (16 channels), 10-bit ADC with internal 1.45 V reference and temperature sensor, up to 10 I²C/Simplified I²C channels, and DMA controller with 4 channels supporting 2-clock transfers between SFR and RAM - all operating within 1.6–5.5 V supply and -40°C to +85°C ambient range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Pinout & Package
Package: 80-pin LQFP, 14 × 14 mm body, 0.65 mm pitch, exposed pad not specified, RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P10/SCK00/SCL00 | SPI clock / I²C clock | Shared pin enables flexible interface selection; requires software configuration for protocol mode. |
| P11/SI00/RxD0/TOOLRxD/SDA00 | SPI input / UART receive / debug RX / I²C data | Multi-function pin supports serial comms and on-chip debugging without external level shifters. |

Key Features
| Feature | Design Value |
|---|---|
| Ultra-low-power HALT/STOP modes | Reduces active current to 66 μA/MHz and standby to 0.57 μA - critical for coin-cell or energy-harvesting systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100MGAFA#V0 | Includes 8 KB data flash; identical pinout, package, and peripheral set. | Required where non-volatile parameter storage (e.g., calibration coefficients) must reside on-chip without external EEPROM. | Select when firmware needs background data flash rewriting during operation (BGO supported). |
| R5F101MGAFB#V0 | Same core, memory, and peripherals; differs only in package - 80-pin LFQFP (0.5 mm pitch) instead of LQFP (0.65 mm pitch). | Used in space-constrained PCBs requiring finer pitch; demands tighter layout tolerances and reflow profile control. | Choose for higher-density boards where 0.5 mm pitch is already standardized and assembly capability exists. |
Compared with R5F100MGAFA#V0, the R5F101MGAFA#V0 reduces BoM cost by eliminating redundant data flash while retaining full code flash and RAM - ideal for fixed-parameter applications; versus R5F101MGAFB#V0, it eases PCB routing and improves solder joint reliability with its 0.65 mm pitch LQFP footprint.

Does the R5F101MGAFA#V0 support real-time clock (RTC) functionality?
Yes, the R5F101MGAFA#V0 integrates a full-featured real-time clock with calendar support (up to 99 years), alarm interrupt, and clock correction capability. It operates independently in STOP mode with only 0.57 μA current draw when powered with RTC and LVD enabled - enabling accurate timekeeping in battery-backed applications without external RTC ICs.
What is the operating voltage and temperature range for the R5F101MGAFA#V0?
The R5F101MGAFA#V0 operates from 1.6 V to 5.5 V over an industrial ambient temperature range of -40°C to +85°C. This wide voltage range supports direct connection to Li-ion, alkaline, or regulated 3.3 V supplies, while the temperature rating validates use in enclosed industrial enclosures and outdoor metering housings without forced cooling.
Which development tools are compatible with the R5F101MGAFA#V0?
The R5F101MGAFA#V0 is fully supported by Renesas CS+ IDE, e² studio (Eclipse-based), and IAR Embedded Workbench for RL78. Debugging uses the on-chip FINE interface via standard JTAG/SWD adapters like E2 emulator Lite or Segger J-Link; no external debug probe license fees apply for basic flash programming and breakpoint debugging.
How many analog-to-digital converter (ADC) channels does the R5F101MGAFA#V0 provide?
The R5F101MGAFA#V0 features a 10-bit successive-approximation ADC with up to 26 input channels, internal 1.45 V reference voltage, and integrated temperature sensor.
