Product details
Overview
R5F104JHDFA#V0 from Renesas is a 52-pin LQFP-0.65mm, industrial-grade RL78/G14 16-bit microcontroller with 256 KB flash, 20 KB RAM, 10-bit ADC (16 channels), and real-time clock. It operates from 1.6–5.5 V, achieves 44 DMIPS at 32 MHz, and supports ultra-low-power HALT/STOP/SNOOZE modes for battery-powered sensor nodes and motor control interfaces.
For engineers reviewing the R5F104JHDFA#V0 datasheet, R5F104JHDFA#V0 pinout, R5F104JHDFA#V0 application, or R5F104JHDFA#V0 equivalent, key selection criteria include its 52-pin LQFP package, 256 KB code flash with data flash shield window, integrated RTC with calendar/alarm, and dual UART + I²C + CSI peripheral set for industrial HMI and smart actuator designs.
Technical Context
The R5F104JHDFA#V0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). It integrates a Data Transfer Controller (DTC) with chain transfer and an Event Link Controller (ELC) enabling direct peripheral-to-peripheral event routing without CPU intervention.
Its power architecture includes on-chip POR, 14-level LVD with interrupt/reset options, and true low-power operation: 66 μA/MHz active current and 0.60 μA in RTC+LVD-only STOP mode. The high-accuracy ±1.0% on-chip oscillator (1–64 MHz selectable) eliminates external crystal dependency for cost-sensitive applications.

Its on-chip high-speed oscillator supports frequencies from 1 MHz to 64 MHz with ±1.0% accuracy across −40°C to +85°C, enabling reliable timing without external crystals in many applications. This performance level supports real-time control loops and protocol stacks like Modbus RTU or LIN 2.x.
Does the R5F104JHDFA#V0 support in-system programming and secure firmware updates?
Yes, the R5F104JHDFA#V0 supports full in-system programming via its on-chip debug interface and includes flash shield window functionality to protect critical bootloader sections. It also implements boot swap capability, allowing safe dual-bank firmware updates with atomic rollback-essential for remote industrial devices where update failure must not compromise operation.
How many analog input channels and what ADC resolution does the R5F104JHDFA#V0 provide?
The R5F104JHDFA#V0 integrates a 10-bit successive approximation ADC with 16 analog input channels (ANI0–ANI15), plus two additional VCOUT outputs usable as analog comparators. It includes an internal 1.45 V reference and on-die temperature sensor, enabling accurate voltage and thermal measurements without external components-ideal for sensor fusion in compact industrial nodes.
What serial communication interfaces are available on the R5F104JHDFA#V0?
The R5F104JHDFA#V0 provides three UART/LIN channels, four to ten I²C/simplified I²C channels, and three to eight CSI (SPI-compatible) channels. These are fully configurable via peripheral I/O redirection registers (PIOR0/PIOR1), allowing flexible pin assignment for board layout optimization and multi-protocol interoperability in complex industrial networks.
What low-power modes does the R5F104JHDFA#V0 support, and what is its lowest current consumption?
The R5F104JHDFA#V0 supports HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it consumes just 0.60 μA-a critical specification for battery-operated sensor nodes requiring multi-year operation.
