Product details
Overview
R5F104MHAFA#V0 from Renesas Electronics is a 80-pin LQFP-0.65 mm pitch, industrial-grade (TA = −40 to +85°C) RL78/G14 16-bit microcontroller with 192 KB flash, 20 KB RAM, and 8 KB data flash. It integrates a 32 MHz RL78 CPU core delivering 44 DMIPS, ultra-low-power operation (66 μA/MHz active, 0.60 μA RTC+LVD), and peripherals including 12-channel 10-bit ADC, dual DAC, RTC, 12× 16-bit timers, UART/SPI/I²C interfaces, and on-chip debug.
For engineers reviewing the R5F104MHAFA#V0 datasheet, R5F104MHAFA#V0 pinout, R5F104MHAFA#V0 application, or R5F104MHAFA#V0 equivalent, this MCU targets cost-sensitive, power-constrained industrial control, sensor hubs, and appliance HMI where mixed-signal integration, code security, and long-term supply stability are critical selection criteria.
Technical Context
The R5F104MHAFA#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It supports multiply/divide/accumulate instructions and 1 MB address space across four register banks.
Its peripheral set includes a Data Transfer Controller (DTC) for autonomous memory transfers, Event Link Controller (ELC) for hardware-triggered peripheral chaining, and background operation (BGO) for concurrent code execution during data flash rewriting - enabling real-time firmware updates without system interruption.

The RL78 core's 3-stage pipeline and optimized instruction set enable consistent performance across voltage and temperature ranges specified for the device.
Does the R5F104MHAFA#V0 support in-system programming and secure firmware updates?
Yes, the R5F104MHAFA#V0 supports full in-system programming via its on-chip debug interface and includes boot swap functionality. This allows validated firmware images to be written to a secondary flash bank while the primary bank remains active, enabling atomic updates. Flash shield window and block erase prohibition features prevent unauthorized access or modification of protected code sections during R5F104MHAFA#V0 operation.
How many analog input channels and what ADC resolution does the R5F104MHAFA#V0 provide?
The R5F104MHAFA#V0 integrates a 10-bit successive approximation ADC with up to 20 analog input channels (ANI0–ANI19), including dedicated VCOUT0/VCOUT1 outputs for comparator-based sensing. It supports internal 1.45 V reference voltage and temperature sensor readout, enabling direct calibration and environmental monitoring without external components in R5F104MHAFA#V0-based designs.
What serial communication interfaces are available on the R5F104MHAFA#V0 and how many instances of each?
The R5F104MHAFA#V0 provides three UART channels (one with LIN-bus support), up to ten I²C/simplified I²C channels, and three to eight CSI (SPI-compatible) channels. Interface count depends on pin multiplexing and configuration; all are software-configurable and supported by the DTC and ELC for autonomous data transfer and event-triggered operation in R5F104MHAFA#V0 applications.
Is the R5F104MHAFA#V0 qualified for industrial temperature range and what packaging option does it use?
Yes, the R5F104MHAFA#V0 is qualified for the industrial temperature range of −40°C to +85°C ('D' field of application) and is supplied in an 80-pin LQFP package with 0.65 mm pitch (RENESAS code PLQP0080JB-E).
