Product details
Overview
R5F104PFDFA#V0 from Renesas is a 100-pin, 5.5-V tolerant RL78/G14 16-bit microcontroller with 96 KB flash, 5.5 KB RAM, and integrated peripherals including 10-bit ADC (16 channels), UART/LIN (4 channels), I²C (10 channels), and RTC. It operates from -40°C to +85°C and targets industrial control panels requiring low-power, mixed-signal processing.
For engineers reviewing the R5F104PFDFA#V0 datasheet, R5F104PFDFA#V0 pinout, R5F104PFDFA#V0 application, or R5F104PFDFA#V0 equivalent, key selection criteria include its LFQFP-100 package, 96 KB code flash with data flash, 10-bit ADC resolution, LIN-capable UARTs, and support for STOP/HALT/SNOOZE low-power modes.
Technical Context
The R5F104PFDFA#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 high-accuracy ±1.0% on-chip oscillator (1–64 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC operation.
Peripheral integration includes Event Link Controller (ELC) for hardware-triggered peripheral chaining, Data Transfer Controller (DTC) for interrupt-driven memory transfers, and background operation (BGO) for concurrent code execution during data flash rewriting - enabling real-time firmware updates without halting application logic.

The R5F104PFDFA#V0 operates up to 32 MHz with a typical current consumption of 66 μA per MHz. At full speed, it delivers 44 DMIPS performance. Its ultra-low-power STOP mode draws only 0.60 μA while retaining RTC and LVD functionality - critical for battery-backed applications. The high-accuracy ±1.0% on-chip oscillator eliminates need for external crystal in many use cases, reducing BOM count and board space.
Does the R5F104PFDFA#V0 support in-system programming and secure firmware updates?
Yes, the R5F104PFDFA#V0 supports full in-system programming via on-chip debug interface and includes multiple security features: flash block erase/write prohibition, flash shield window for protected memory regions, and boot swap functionality for safe dual-bank firmware updates. These capabilities enable field firmware upgrades without requiring physical access or specialized programmers, and prevent unauthorized modification of critical code sections.
How many serial communication interfaces does the R5F104PFDFA#V0 provide, and which protocols are supported?
The R5F104PFDFA#V0 provides up to 4 UART/LIN channels, 10 I²C/simplified I²C channels, and 3–8 CSI (SPI-compatible) channels. All UARTs support LIN 2.2 protocol, enabling direct integration into automotive and industrial networks. I²C channels operate at standard/fast-mode speeds, and CSI supports master/slave operation with configurable frame formats - allowing flexible connectivity to displays, sensors, EEPROMs, and other peripherals without external level shifters.
What analog peripherals are integrated into the R5F104PFDFA#V0, and what are their key specifications?
The R5F104PFDFA#V0 integrates a 10-bit successive approximation ADC with 16 input channels, internal 1.45 V reference voltage, and on-die temperature sensor. It also includes an 8-bit D/A converter with up to two output channels (0 V to VDD range) and real-time output capability. Additionally, it supports up to two comparator channels with selectable internal/external reference and window mode - enabling precision analog monitoring, closed-loop control, and threshold detection without external components.
Is the R5F104PFDFA#V0 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 devices in the 100-pin LQFP (0.65 mm pitch) package - including R5F104PFDFA#V0, R5F104PJGFA#V0, and R5F104PFAFA#V0 - share identical pinouts and electrical characteristics. This allows direct substitution during prototyping or production ramp-up based on memory or temperature grade requirements, without PCB redesign. Functional differences (e.g., flash size, RAM, temp grade) are implemented internally and do not affect pin behavior or timing.
