Renesas R5F104BGGFP#10

Overview

R5F104BGGFP#10 from Renesas is a 32-bit RL78/G14 microcontroller with 128 KB code flash, 8 KB data flash, and 12 KB RAM, operating at up to 32 MHz (44 DMIPS), featuring ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD mode), 10-bit ADC (16 channels), UART/SPI/I²C interfaces, and real-time clock - deployed in industrial sensor nodes and battery-powered control systems.

For engineers reviewing the R5F104BGGFP#10 datasheet, R5F104BGGFP#10 pinout, R5F104BGGFP#10 application, or R5F104BGGFP#10 equivalent, key selection criteria include its LFQFP-48 package, -40°C to +105°C industrial temperature grade (G), integrated voltage detector (14-level LVD), event link controller (ELC) for peripheral coordination, and hardware DTC for zero-CPU-load data transfers.

Technical Context

The R5F104BGGFP#10 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz high-speed mode) to 30.5 µs (32.768 kHz ultra-low-speed mode); it integrates a 12-bit interval timer, calendar-based RTC with alarm/correction, and watchdog timer with dedicated low-speed oscillator.

Its peripheral set includes Timer Array Unit (TAU) with 8 channels, 16-bit timers (TAU + Timer RJ/RD/RG), simplified SPI (CSI), UART/LIN, I²C, and dual-channel comparator with window/high-speed/low-speed modes - all configurable via Event Link Controller to reduce software overhead and interrupt latency.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating for the R5F104BGGFP#10?

The R5F104BGGFP#10 operates at up to 32 MHz with a measured performance of 44 DMIPS. This value is derived from the RL78 CPU core's 3-stage pipeline architecture and instruction mix benchmarking per EEMBC CoreMark methodology. The R5F104BGGFP#10 achieves this performance within its 1.6–5.5 V supply range and supports dynamic clock switching between internal oscillators (1–64 MHz) and external crystals.

Does the R5F104BGGFP#10 support in-system programming and secure firmware updates?

Yes, the R5F104BGGFP#10 supports full in-system programming via its on-chip debug interface and boot swapping mechanism. It includes flash shield window protection to prevent unauthorized access to code memory, and self-programming capability allows safe firmware updates without external tools. The R5F104BGGFP#10 also supports background operation (BGO) so application code continues running during data flash rewrites.

What are the analog capabilities of the R5F104BGGFP#10, including ADC resolution, channel count, and reference options?

The R5F104BGGFP#10 integrates a 10-bit successive-approximation ADC with 16 analog input channels, selectable internal 1.45 V reference or external AVREFP/AVREFM inputs, and an on-die temperature sensor. It supports simultaneous sampling on multiple channels via hardware triggering and includes built-in offset/gain calibration registers. The R5F104BGGFP#10 does not include a DAC or operational amplifier.

How does the Event Link Controller (ELC) improve real-time responsiveness in the R5F104BGGFP#10?

The ELC in the R5F104BGGFP#10 enables direct hardware linking of peripheral events - for example, a timer overflow can trigger ADC conversion start without CPU involvement or interrupt latency. This reduces jitter in time-critical sequences like motor commutation or sensor sampling. The R5F104BGGFP#10 supports up to 26 event sources linked to 19 peripheral functions, configured via dedicated ELC registers.

What is the industrial temperature grade and package type of the R5F104BGGFP#10, and how is it marked?

The R5F104BGGFP#10 is qualified for -40°C to +105°C operation (G-grade industrial), housed in a 48-pin LFQFP package with 0.5 mm pitch (Renesas code FP). The "G" in the part number denotes the extended temperature range, and "FP" specifies the LQFP variant; the "#10" suffix indicates tray packaging per Renesas standard. The R5F104BGGFP#10 uses PLQP0048KF-A code for its package outline.
