Product details
Overview
R5F104FAAFP#10 from Renesas is a 44-pin LQFP, 96 KB flash, 12 KB RAM RL78/G14 16-bit microcontroller with ultra-low power consumption (66 μA/MHz), integrated 10-bit ADC (20 channels), RTC, and dual UART/LIN interfaces - deployed in battery-powered industrial sensor nodes and smart metering front-ends.
For engineers reviewing the R5F104FAAFP#10 datasheet, R5F104FAAFP#10 pinout, R5F104FAAFP#10 application, or R5F104FAAFP#10 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm pitch package, -40°C to +85°C industrial temperature grade (A-field), 96 KB code flash with data flash shield window, and support for background data flash rewriting during program execution.
Technical Context
The R5F104FAAFP#10 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 an Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention.
Its power management includes HALT, STOP, and SNOOZE modes, with real-time clock operation at 0.60 μA and on-chip voltage detector (LVD) offering 14 selectable reset/ interrupt thresholds - critical for brown-out resilience in unregulated supply environments.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F104FAAFP#10?
The R5F104FAAFP#10 operates up to 32 MHz using its high-speed on-chip oscillator with ±1.0% accuracy. At this frequency, it consumes 66 μA per MHz under active operation - translating to approximately 2.1 mA total at 32 MHz with all peripherals disabled. Its ultra-low-power STOP mode draws just 0.60 μA when only RTC and LVD remain active.
Does the R5F104FAAFP#10 support in-system programming and secure firmware updates?
Yes, the R5F104FAAFP#10 supports full in-system programming via on-chip debug interface and includes flash shield window functionality to prevent unauthorized read/write access to protected memory regions. It enables boot swapping and secure firmware updates without external programmers - critical for remote industrial deployments where R5F104FAAFP#10 serves as the trusted execution anchor.
How many UART/LIN interfaces does the R5F104FAAFP#10 integrate, and are they independently configurable?
The R5F104FAAFP#10 integrates three UART/LIN channels, each fully independent with dedicated baud rate generators, FIFO buffers, and LIN-specific features like sync-break detection and checksum calculation. All three channels can operate simultaneously - for example, one as LIN master for actuator control, one as UART for debug, and one as Modbus RTU slave - without resource contention in the R5F104FAAFP#10's peripheral architecture.
What analog capabilities does the R5F104FAAFP#10 provide for sensor interfacing?
The R5F104FAAFP#10 includes a 10-bit successive-approximation ADC with up to 20 input channels, internal 1.45 V reference voltage, and integrated temperature sensor. It supports programmable sampling time, scan mode, and hardware trigger sources (e.g., timer or ELC). No external reference or signal conditioning is required for direct connection to resistive sensors, thermistors, or 0–5 V analog outputs - a key advantage in compact R5F104FAAFP#10-based sensor designs.
Is the R5F104FAAFP#10 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 devices in the 44-pin LQFP-0.8 mm pitch package - including R5F104FAAFP#10, R5F104GAFA#10, and R5F104FEAFP#10 - share identical pinouts and electrical characteristics. This allows direct PCB reuse across memory variants, enabling scalable design families where firmware and layout remain consistent while flash/RAM capacity scales with application complexity - a verified compatibility confirmed in Renesas' RL78/G14 ordering guide.
