Product details
Overview
R5F101MHAFB#30 from Renesas is a 80-pin LFQFP-0.5mm-pitch, 192 KB flash, 8 KB data flash, 16 KB RAM RL78/G13 16-bit MCU with ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), 1.6–5.5 V supply, and integrated peripherals including 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, RTC, and watchdog - deployed in industrial motor control and sensor interface modules.
For engineers reviewing the R5F101MHAFB#30 datasheet, R5F101MHAFB#30 pinout, R5F101MHAFB#30 application, or R5F101MHAFB#30 equivalent, key selection criteria include its 80-pin LFQFP package, absence of on-chip data flash (R5F101x series), -40°C to +105°C industrial temperature grade (G suffix), and support for SNOOZE mode for low-latency wake-up from ultra-low-power states.
Technical Context
The R5F101MHAFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 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, real-time clock with calendar/alarm, and hardware multiplier/divider for efficient math operations in embedded control loops.
Its peripheral set includes up to 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, 3–10-channel I²C/Simplified I²C, 2–4-channel UART with LIN support, and 2–8-channel CSI (SPI-compatible serial interface), all configurable via dedicated SFRs and DMA channels for deterministic timing-critical tasks.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
Package: 80-pin LFQFP (12 × 12 mm, 0.50-mm pitch), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P10/SCK00/SCL00 | Serial Clock Input/Output | Shared SPI clock (CSI) and I²C clock - requires external pull-up for I²C mode |
| P11/SI00/RxD0/TOOLRxD/SDA00 | Serial Data Input / UART RX / I²C Data | Multi-function pin supporting SPI input, UART receive, debug tool interface, and I²C bidirectional data |

| P40/INTP0/TOOL0 | External Interrupt 0 / Debug Interface | Dual-role pin for edge-triggered interrupt sourcing and on-chip debugging connection |
| P50/CLKP/CLKOUT | System Clock Output | Configurable clock output pin - supports frequency division for system-level timing synchronization |
Key Features
| Feature | Design Value |
|---|---|
| SNOOZE mode operation | Enables UART/LIN or CSI interrupt wake-up while CPU remains halted - reduces average power in polling-based communication |
| Hardware multiplier/divider | 16×16→32-bit multiply, 32÷32→32-bit divide, and MAC operations execute in fixed cycles - accelerates PID and filter computations |
| Background operation (BGO) | Not applicable - R5F101x series lacks on-chip data flash, so BGO for data flash rewrite is unavailable |
| On-chip voltage detector (LVD) | 14-level programmable LVD with interrupt/reset options - provides robust brown-out protection across wide VDD range |
| DMA controller | 4-channel DMA with 2-clock transfer between SFR and RAM - eliminates CPU overhead for ADC-to-memory or UART-to-buffer transfers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100MHAFB#30 | Same 80-pin LFQFP package and 192 KB flash, but includes 8 KB on-chip data flash and supports background operation (BGO). | Preferred where field firmware updates or parameter storage require non-volatile data retention without external EEPROM. | Select when data logging, calibration storage, or secure boot configuration persistence is required. |
| R5F101MJAFB#30 | Identical R5F101x series (no data flash), same 80-pin LFQFP, but 256 KB flash and 20 KB RAM - pin-compatible upgrade path. | Used in next-generation designs requiring larger code footprint for enhanced connectivity stacks or advanced diagnostics. | Choose for forward-compatible designs needing headroom for feature expansion without PCB redesign. |
Compared with R5F101MHAFB#30, R5F100MHAFB#30 adds data flash for persistent storage at the cost of higher active current, while R5F101MJAFB#30 offers scalable memory headroom within the same footprint - enabling lifecycle extension without layout changes.

FAQ
What is the flash memory configuration of the R5F101MHAFB#30?
The R5F101MHAFB#30 contains 192 KB of on-chip code flash memory and no data flash - consistent with the R5F101x series designation indicating data flash omission. This simplifies firmware update architecture but requires external non-volatile storage for parameter retention. The flash block size is 1 KB, and security features prohibit unauthorized block erase or rewriting.
Does the R5F101MHAFB#30 support background operation (BGO) for data flash writes?
No, the R5F101MHAFB#30 does not support background operation (BGO) because it lacks on-chip data flash memory - BGO is only available on R5F100x series devices that include data flash. Firmware must use standard flash programming routines with CPU suspension during write/erase cycles.
What is the operating temperature grade of the R5F101MHAFB#30?
The R5F101MHAFB#30 is rated for -40°C to +105°C operation (G-grade), verified per Renesas specification R01DS0131EJ0380. This makes it suitable for under-hood automotive auxiliary systems, industrial drives, and factory-floor equipment where ambient thermal stress exceeds commercial-grade limits.
How many ADC channels does the R5F101MHAFB#30 support, and what is their resolution?
The R5F101MHAFB#30 integrates a 10-bit successive approximation register (SAR) ADC with up to 26 analog input channels. It includes an internal 1.45 V reference voltage and a calibrated temperature sensor, enabling accurate ratiometric measurements and thermal monitoring without external components.
Is the R5F101MHAFB#30 pin-compatible with other RL78/G13 80-pin variants?
Yes, the R5F101MHAFB#30 shares identical 80-pin LFQFP mechanical dimensions and pinout with all other RL78/G13 devices in the same package variant (e.g., R5F101MJAFB#30, R5F100MHAFB#30), enabling drop-in replacement for memory or feature upgrades - provided software accounts for differences in data flash presence or RAM size.
