Product details
Overview
R5F104PKGFA#10 from Renesas Electronics is a 48-pin LQFP-packaged 16-bit RL78/G14 microcontroller with 256 KB flash, 8 KB data flash, and 24 KB RAM, operating from 1.6 V to 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 - deployed in industrial motor control and sensor interface modules.
For engineers reviewing the R5F104PKGFA#10 datasheet, R5F104PKGFA#10 pinout, R5F104PKGFA#10 application, or R5F104PKGFA#10 equivalent, key selection criteria include its -40°C to +105°C industrial-grade temperature rating (G-suffix), 48-pin LFQFP 0.5 mm pitch package, and support for background data flash rewriting with 1M-cycle endurance - critical for field-upgradable embedded firmware.
Technical Context
The R5F104PKGFA#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode), and includes multiply/divide/accumulate instructions with 1 MB address space. It integrates an Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention.
Its power management includes on-chip POR and voltage detector (LVD) with 14 selectable threshold levels, plus real-time clock with calendar, alarm, and clock correction functions. The DTC supports normal, repeat, and block transfer modes activated by 19–26 event sources, reducing CPU load during memory-to-peripheral data movement.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104PKGFA#10?
The R5F104PKGFA#10 operates at up to 32 MHz with a measured performance of 44 DMIPS. This rating reflects integer instruction throughput under standard benchmark conditions using the RL78 CPU core's 3-stage pipeline and optimized compiler settings. The on-chip high-speed oscillator supports ±1.0% accuracy across its full operating voltage and temperature range, ensuring deterministic timing for real-time control loops in the R5F104PKGFA#10.
Does the R5F104PKGFA#10 support background data flash rewriting while executing code from main flash memory?
Yes, the R5F104PKGFA#10 supports Background Operation (BGO) for data flash rewriting. During BGO, the CPU can execute instructions from program flash memory while the data flash is being rewritten - eliminating interrupt latency penalties and enabling seamless firmware parameter updates. This capability is confirmed in the R5F104PKGFA#10 datasheet section "Data Flash Memory" and requires proper configuration of the FLMCR register and flash library initialization.
What is the purpose of the REGC pin on the R5F104PKGFA#10, and how must it be connected?
The REGC pin on the R5F104PKGFA#10 connects to the internal voltage regulator's stabilization capacitor. It must be tied to VSS via a 0.47 µF to 1.0 µF ceramic capacitor placed as close as possible to the pin. Failure to do so risks unstable internal regulation, leading to erratic reset behavior or flash programming errors. This requirement is explicitly stated in the R5F104PKGFA#10 pin configuration diagrams and electrical characteristics tables.
How many analog input channels does the 10-bit ADC in the R5F104PKGFA#10 support, and what reference options are available?
The R5F104PKGFA#10 integrates a 10-bit successive-approximation ADC with 16 analog input channels (ANI0–ANI15). It supports two reference voltage sources: the internal 1.45 V reference (VREF) and the externally supplied AVREFP/AVREFM differential pair. Channel selection, resolution, and reference source are configured via the ADCSR and ADSHR registers, and the ADC operates across the full 1.6 V to 5.5 V supply range of the R5F104PKGFA#10.
Is the R5F104PKGFA#10 qualified for industrial temperature operation, and what does the 'G' suffix indicate?
Yes, the R5F104PKGFA#10 is qualified for industrial temperature operation from -40°C to +105°C. The 'G' in the part number denotes this extended temperature grade, distinguishing it from 'A' (consumer, -40°C to +85°C) and 'D' (industrial, -40°C to +85°C) variants. This qualification is verified per JEDEC JESD22-A104 and applies to all electrical specifications in the R5F104PKGFA#10 datasheet under those thermal conditions.
