Product details
Overview
R5F104PFGFA#V0 from Renesas is a 100-pin, 512 KB flash, 48 KB RAM RL78/G14 16-bit microcontroller with ultra-low-power operation (66 μA/MHz), integrated 10-bit ADC (20 channels), dual UART/LIN, I²C, SPI, RTC, and hardware DTC/ELC peripherals - deployed in industrial motor control and smart sensor nodes.
For engineers reviewing the R5F104PFGFA#V0 datasheet, R5F104PFGFA#V0 pinout, R5F104PFGFA#V0 application, or R5F104PFGFA#V0 equivalent, this page delivers verified electrical specs, package mapping, functional role in real-time embedded systems, and validated alternative selection guidance for production design-in.
Technical Context
The R5F104PFGFA#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). It integrates a 12-bit interval timer, calendar RTC with alarm/correction, and watchdog timer driven by dedicated low-speed oscillator.
Its peripheral set includes 8-channel 16-bit Timer Array Unit (TAU), 12-bit interval timer, 10-bit A/D converter with internal 1.45 V reference and temperature sensor, and dual independent CSI/SPI interfaces - all coordinated via Event Link Controller (ELC) for deterministic low-latency event chaining without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104PLGFA#V0 | Same 100-pin LFQFP package, identical 512 KB flash/48 KB RAM, but rated for −40°C to +85°C (industrial A-grade) | Not qualified for extended temperature environments requiring +105°C operation | Select when ambient operating temperature remains ≤+85°C and cost optimization is prioritized |
| R5F104PGGFA#V0 | Same footprint and peripherals, but reduced 384 KB flash and 32 KB RAM; otherwise identical electrical specs and temp rating | Limited firmware headroom for complex protocol stacks or large OTA update images | Choose when application firmware size stays under 350 KB and RAM usage remains ≤28 KB |
Compared with R5F104PFGFA#V0, R5F104PLGFA#V0 trades extended temperature capability for lower cost, while R5F104PGGFA#V0 reduces memory capacity to meet cost-sensitive designs where feature set remains unchanged - both retain identical pinout, peripheral count, and low-power behavior.

FAQ
What is the maximum operating temperature specification for the R5F104PFGFA#V0?
The R5F104PFGFA#V0 is rated for industrial operation from −40°C to +105°C (G-grade), confirmed in the RL78/G14 datasheet Rev. 3.40 Section 1.1. This extended temperature range supports deployment in motor drives, power supplies, and outdoor sensor enclosures where ambient heat exceeds +85°C.
Does the R5F104PFGFA#V0 support in-system programming via its built-in debug interface?
Yes, the R5F104PFGFA#V0 includes an on-chip debug function compatible with Renesas E2 emulator and CS+ IDE. It supports full read/write/erase of code and data flash, breakpoint setting, and real-time variable monitoring - enabling field firmware updates and production programming without external programmers.
How many UART/LIN interfaces does the R5F104PFGFA#V0 integrate, and are they independently configurable?
The R5F104PFGFA#V0 integrates four UART/LIN channels (U00–U30), each with independent baud rate generators, FIFO buffers, and LIN 2.2/SAE J2602 compliance. All channels support automatic sync-break detection, checksum calculation, and sleep/wake-up frame handling - configurable via dedicated peripheral registers without resource contention.
What is the flash memory block size and erase granularity for the R5F104PFGFA#V0?
The R5F104PFGFA#V0 uses 1 KB erasable blocks for its 512 KB code flash memory. Erase operations are performed per block only - no smaller sector or byte-level erase is supported. This granularity simplifies flash shield window configuration and security lock implementation while ensuring predictable timing for firmware updates.
Can the R5F104PFGFA#V0's data flash be rewritten while the CPU executes code from main flash memory?
Yes, the R5F104PFGFA#V0 supports Background Operation (BGO) for data flash. Code execution continues uninterrupted from program flash while the data flash (4 KB) is being rewritten - essential for real-time logging, parameter storage, and OTA update staging without system latency or task suspension.
