Product details
Overview
R5F101MHAFA#10 from Renesas is an RL78/G13 16-bit microcontroller with 192 KB flash, 8 KB data flash, and 16 KB RAM, operating at up to 32 MHz with 41 DMIPS performance. It features ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD), 80-pin LQFP-0.65mm package, and integrated peripherals including 16-bit timers, 10-bit ADC (26 channels), UART, I²C, CSI, RTC, and DMA - deployed in battery-powered industrial sensors and smart metering systems.
For engineers reviewing the R5F101MHAFA#10 datasheet, R5F101MHAFA#10 pinout, R5F101MHAFA#10 application, or R5F101MHAFA#10 equivalent, key selection criteria include its 192 KB code flash with self-programming, 10-bit ADC accuracy over 1.6–5.5 V supply, 80-pin LQFP footprint for high peripheral density, and -40°C to +85°C industrial temperature grade.
Technical Context
The R5F101MHAFA#10 implements the RL78 CPU core with a 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). It integrates a high-accuracy ±1.0% on-chip oscillator (1–32 MHz selectable) and operates across 1.6–5.5 V supply voltage.
It includes dedicated low-power modes (HALT, STOP, SNOOZE), on-chip POR and 14-level LVD, background operation for data flash rewriting (BGO), and hardware multiplier/divider/accumulator for real-time signal processing - all optimized for deterministic embedded control in resource-constrained environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100MHAFA#10 | Includes 8 KB data flash; R5F101MHAFA#10 omits data flash but retains same code flash, RAM, and peripherals | Targeted at applications requiring persistent parameter storage (e.g., calibration tables, event logs) | Select R5F100MHAFA#10 only when data flash functionality is required; otherwise R5F101MHAFA#10 reduces cost and simplifies flash management |
| R5F101MHGFA#10 | Same core, memory, and peripherals but rated for -40°C to +105°C (G-grade industrial) | Required for under-hood automotive or high-temperature factory environments | Choose R5F101MHGFA#10 when ambient operating temperature exceeds +85°C; otherwise R5F101MHAFA#10 suffices for standard industrial use |
Compared with R5F100MHAFA#10, the R5F101MHAFA#10 removes data flash to reduce cost and complexity where non-volatile parameter storage is handled externally; compared with R5F101MHGFA#10, it trades extended temperature rating for lower unit price in applications staying within -40°C to +85°C.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F101MHAFA#10?
The R5F101MHAFA#10 operates at up to 32 MHz with a peak performance of 41 DMIPS. Its RL78 CPU core achieves this via a 3-stage pipeline CISC architecture and supports configurable instruction timing - from 0.03125 μs (high-speed mode) down to 30.5 μs (ultra-low-speed subsystem clock mode). This enables precise trade-offs between throughput and power in real-time embedded applications.
Does the R5F101MHAFA#10 include data flash memory?
No, the R5F101MHAFA#10 does not include data flash memory. Per Renesas part numbering convention, the "101" prefix indicates no data flash, distinguishing it from "100"-series variants like R5F100MHAFA#10 which integrate 8 KB of data flash. All other specifications - 192 KB code flash, 16 KB RAM, peripherals, and package - remain identical between the two.
What package type and pin count does the R5F101MHAFA#10 use?
The R5F101MHAFA#10 uses an 80-pin LQFP package with 0.65-mm pitch (JEDEC MS-026), measuring 14 mm × 14 mm. This package is documented in Renesas datasheet R01DS0131EJ0380 as the standard footprint for 80-pin RL78/G13 devices, supporting full I/O access, thermal dissipation, and compatibility with standard reflow and inspection processes.
What are the supported low-power modes on the R5F101MHAFA#10?
The R5F101MHAFA#10 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, current consumption drops to 0.57 μA. HALT mode reduces active current to 66 μA/MHz. These modes are controlled via software registers and integrate with on-chip POR, LVD, and watchdog timer to maintain system integrity during deep sleep.
Which communication interfaces are integrated into the R5F101MHAFA#10?
The R5F101MHAFA#10 integrates UART (up to 4 channels, LIN-capable), I²C/Simplified I²C (up to 10 channels), and CSI (Simplified SPI, up to 8 channels). All interfaces support shared pin mapping and programmable clock dividers, enabling flexible peripheral assignment without external multiplexing - critical for compact industrial control and sensor hub designs.
