Overview
R5F100MGAFA#10 from Renesas is an RL78/G13 80-pin LQFP-0.65mm microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, 32 MHz max CPU speed, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), designed for battery-powered industrial control and sensor interface applications.
For engineers reviewing the R5F100MGAFA#10 datasheet, R5F100MGAFA#10 pinout, R5F100MGAFA#10 application, or R5F100MGAFA#10 equivalent, key selection criteria include integrated RTC with calendar/alarm, 10-bit 26-channel ADC with internal temperature sensor, dual UART/LIN support, and hardware DMA for deterministic real-time peripheral handling.
Technical Context
The R5F100MGAFA#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a high-accuracy ±1.0% on-chip oscillator across 1.8–5.5 V and -20 to +85°C.
Its power management includes HALT, STOP, and SNOOZE modes, plus on-chip POR and 14-level LVD with selectable interrupt/reset. The MCU supports background data flash rewriting (BGO), self-programming with boot swap, and flash shield window security.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100MGAFB#V0 | Same core, memory, and peripherals but in 80-pin LFQFP-0.5mm package - 2.0 mm smaller footprint, tighter pitch | Preferred for space-constrained designs where PCB rework tolerance is high and automated assembly is available | Select when board area is critical and assembly process supports 0.5 mm pitch; verify thermal dissipation under full load |
| R5F101MGAFB#V0 | Omits 8 KB data flash; retains 128 KB code flash, 12 KB RAM, and identical peripheral set | Suitable for applications storing calibration or runtime parameters externally (e.g., EEPROM or SD card) | Choose when data retention requirements are met by external non-volatile memory and BOM cost reduction is prioritized |
Compared with R5F100MGAFA#10, the R5F100MGAFB#V0 offers identical functionality in a denser package requiring finer layout tolerances, while R5F101MGAFB#V0 removes data flash to lower unit cost-making it viable only when external NV memory is already present in the system architecture.

The R5F100MGAFA#10 supports a maximum CPU clock frequency of 32 MHz using the high-speed on-chip oscillator, delivering 41 DMIPS performance. This speed is achievable across the full 1.6–5.5 V supply range and -40°C to +85°C ambient temperature, with oscillator accuracy maintained at ±1.0% under those conditions.
Does the R5F100MGAFA#10 include an integrated real-time clock (RTC)?
Yes, the R5F100MGAFA#10 includes a fully featured RTC with calendar support (up to 99 years), alarm function, and clock correction capability. It operates independently in STOP mode using either the internal 32.768 kHz oscillator or an external crystal connected to P30/RTCCLK, consuming only 0.57 μA in that low-power state.
How much data flash memory does the R5F100MGAFA#10 provide, and what is its endurance?
The R5F100MGAFA#10 provides 8 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. It supports background operation (BGO), allowing program execution from code flash while rewriting data flash-enabling seamless parameter updates without interrupting real-time tasks.
What communication interfaces are available on the R5F100MGAFA#10?
The R5F100MGAFA#10 integrates up to 10 I²C/Simplified I²C channels, 4 UART/LIN channels, and 8 CSI (SPI-compatible) channels. UART0 and UART1 both support LIN 2.2 physical layer, making the R5F100MGAFA#10 suitable for automotive body electronics and industrial bus gateways requiring protocol flexibility.
Is the R5F100MGAFA#10 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 80-pin LQFP-0.65mm package-including R5F100MGAFA#10, R5F100MFAFA#10, and R5F100MLAFA#10-share identical pinouts and electrical characteristics.
