Overview
R5F104FCAFP#10 from Renesas is a 44-pin LQFP-packaged RL78/G14 16-bit microcontroller with 96 KB flash, 12 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at up to 32 MHz (44 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes, integrated RTC, 10-bit ADC (16 channels), and UART/I²C/CSI interfaces for industrial control and sensor node applications.
For engineers reviewing the R5F104FCAFP#10 datasheet, R5F104FCAFP#10 pinout, R5F104FCAFP#10 application, or R5F104FCAFP#10 equivalent, key selection considerations include its -40°C to +85°C industrial temperature grade (D suffix), 44-pin 0.8 mm pitch LQFP package, 96 KB code flash with security lock, and support for background data flash rewriting during program execution.
Technical Context
The R5F104FCAFP#10 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), and includes multiply/divide/accumulate instructions within a 1 MB address space. 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 analog subsystem comprises a 10-bit ADC with 16 input channels, internal 1.45 V reference and temperature sensor, plus dual 8-bit DAC outputs (0–VDD range) with real-time update capability. Power management includes on-chip POR, 14-level LVD with interrupt/reset options, and true low-power operation down to 0.60 µA in RTC+LVD-only mode.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F104FCAFP#10?
The R5F104FCAFP#10 operates at up to 32 MHz with a peak performance of 44 DMIPS. Its high-accuracy on-chip oscillator maintains ±1.0% stability across 1.8–5.5 V and -20 to +85°C, eliminating need for external crystals in many timing-critical applications. This frequency enables real-time processing of sensor data, motor control loops, and communication stack execution without performance bottlenecks.
Does the R5F104FCAFP#10 support in-system programming and secure firmware updates?
Yes, the R5F104FCAFP#10 supports full in-system programming via its on-chip debug interface and includes flash shield window protection. It enables secure firmware updates using background data flash rewriting - allowing new parameters or calibration data to be written while the application runs from code flash. The security function also prohibits unauthorized block erasure or reading of protected flash regions.
What analog peripherals are integrated into the R5F104FCAFP#10 and how are they configured?
The R5F104FCAFP#10 integrates a 10-bit ADC with 16 input channels, internal 1.45 V reference voltage, and on-chip temperature sensor - all accessible through P20–P27 pins. It also includes two 8-bit DACs with 0–VDD output range and real-time update capability. Configuration is performed via dedicated peripheral registers; no external components are required for basic analog measurement or waveform generation.
How does the R5F104FCAFP#10 achieve ultra-low power consumption in industrial environments?
The R5F104FCAFP#10 achieves ultra-low power via multiple hardware-optimized modes: HALT (66 µA/MHz), STOP (0.60 µA with RTC+LVD only), and SNOOZE (fast wake-up from peripheral events). Its industrial -40°C to +85°C rating ensures stable operation across wide ambient ranges, and the on-chip LVD with 14 selectable thresholds prevents malfunction during brown-out conditions without external supervision circuitry.
Which communication interfaces are available on the R5F104FCAFP#10 and what are their key capabilities?
The R5F104FCAFP#10 provides UART/LIN ×3 (with automatic LIN header detection), I²C ×4 (standard/fast-mode up to 400 kHz), and CSI (SPI-compatible) ×3 channels. All interfaces support multi-master arbitration, clock stretching, and configurable baud rates. UART channels include LIN bus support for automotive diagnostics, while I²C and CSI enable reliable sensor and display interfacing with minimal external components.
