Product details
Overview
R5F101MHAFB#V0 from Renesas is a 32-bit RL78/G13 microcontroller with 128 KB flash memory, 12 KB RAM, and no data flash, housed in an 80-pin LFQFP (0.5-mm pitch) package. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes including STOP (0.57 μA) and HALT for battery-powered industrial sensors and motor control interfaces.
For engineers reviewing the R5F101MHAFB#V0 datasheet, R5F101MHAFB#V0 pinout, R5F101MHAFB#V0 application, or R5F101MHAFB#V0 equivalent, key selection criteria include its 80-pin LFQFP footprint, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (D), integrated RTC and 10-bit ADC with 26 channels, and support for LIN-bus UART and simplified SPI peripherals.
Technical Context
The R5F101MHAFB#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 ultra-low-speed mode). Its memory map spans 1 MB address space, with dedicated SFR regions and banked 8-bit general-purpose registers.
Power management includes on-chip POR and LVD with 14 selectable voltage detection levels, while peripheral integration features 16-channel 16-bit timers, one 12-bit interval timer, one real-time clock with calendar/alarm functions, and a watchdog timer driven by a dedicated low-speed oscillator - all optimized for deterministic timing in embedded control loops.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100MHAFB#V0 | Includes 8 KB data flash memory; otherwise identical core, peripherals, and package | Required when firmware needs non-volatile parameter storage without external EEPROM | Select if field-updatable calibration data or event logs must be retained during power loss |
| R5F101MGAFB#V0 | Same family, 48-pin LFQFP package, 96 KB flash, 8 KB RAM, no data flash | Used in space-constrained designs where 52 fewer pins and reduced memory suffice | Choose for cost-optimized, lower-I/O applications such as simple sensor transmitters or LED drivers |
Compared with R5F100MHAFB#V0, the R5F101MHAFB#V0 trades data flash for marginally lower BOM cost and identical real-time performance, while R5F101MGAFB#V0 reduces pin count and memory to fit compact PCB layouts - both alternatives retain the same RL78/G13 instruction set and peripheral register compatibility.

FAQ
What is the flash memory configuration of the R5F101MHAFB#V0?
The R5F101MHAFB#V0 contains 128 KB of code flash memory organized in 1 KB blocks, with flash shield window and block erase prohibition security features. It does not include on-chip data flash memory - confirmed by the '101' prefix in the part number per Renesas RL78/G13 naming convention, which explicitly denotes zero data flash capacity.
Does the R5F101MHAFB#V0 support LIN bus communication?
Yes, the R5F101MHAFB#V0 supports LIN bus communication through its UART peripherals, which are LIN 2.2 compliant. Two to four UART channels are available, each capable of LIN frame transmission and reception with automatic checksum calculation and sync field detection - verified in the RL78/G13 datasheet section 1.1 Features under "Serial interface".
What is the operating temperature range for the R5F101MHAFB#V0?
The R5F101MHAFB#V0 is rated for industrial operation from -40°C to +85°C (D-grade), as indicated by the 'D' suffix in its full ordering code structure. This temperature specification is validated across all electrical parameters in the official Renesas datasheet R01DS0131EJ0380 and applies to the LFQFP-80 package variant.
How many ADC channels does the R5F101MHAFB#V0 provide?
The R5F101MHAFB#V0 provides up to 26 analog input channels for its 10-bit A/D converter, with support for internal reference voltage (1.45 V) and temperature sensor readings. This channel count is confirmed in the RL78/G13 datasheet section 1.1 Features under "A/D converter", and applies specifically to 80-pin and larger packages like the LFQFP-80.
Is the R5F101MHAFB#V0 pin-compatible with other RL78/G13 variants?
No, the R5F101MHAFB#V0 is not pin-compatible with smaller-package RL78/G13 variants due to its 80-pin LFQFP footprint. While it shares identical peripheral register maps and instruction set with other G13 devices, pin mapping differs across package types (e.g., 48-pin vs. 80-pin), and no documentation confirms pin-to-pin compatibility with alternate part numbers - users must validate PCB layout against the specific 80-pin pinout diagram.
