Renesas R5F104BGGFP#30

Overview

R5F104BGGFP#30 from Renesas is a 32-bit RL78/G14 microcontroller with 128 KB flash, 12 KB RAM, and 48 KB data flash, operating from 1.6–5.5 V at -40°C to +105°C (industrial G-grade). It delivers 44 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates 10-bit ADC (16 channels), UART/SCI/I²C interfaces, and real-time clock for embedded control in industrial sensors and motor drives.

FAQ

What is the maximum operating frequency and corresponding performance of the R5F104BGGFP#30?

The R5F104BGGFP#30 operates at up to 32 MHz using its on-chip high-speed oscillator, delivering 44 DMIPS of processing performance. Its RL78 CPU core achieves this with a 3-stage pipeline and supports instruction execution times ranging from 0.03125 µs (at 32 MHz) to 30.5 µs (at 32.768 kHz), enabling both high-speed control and ultra-low-power RTC operation within the same device.

Does the R5F104BGGFP#30 support in-system programming and secure firmware updates?

Yes, the R5F104BGGFP#30 supports full in-system programming via its on-chip debug interface and boot swapping capability. It includes flash shield window protection to restrict write access to designated memory regions, and block erase prohibition to prevent accidental corruption of bootloader or security keys - enabling secure, field-upgradable firmware deployments without external programmers.

What analog peripherals are integrated into the R5F104BGGFP#30, and how are they calibrated?

The R5F104BGGFP#30 integrates a 10-bit SAR ADC with 16 input channels, internal 1.45 V reference voltage, and an on-chip temperature sensor. Calibration is supported via factory-trimmed reference values stored in ROM, and users can perform offset/gain calibration using the ADC's built-in self-test mode - ensuring ≤±2 LSB integral nonlinearity across the full -40°C to +105°C operating range.

How does the R5F104BGGFP#30 manage power in battery-operated applications?

The R5F104BGGFP#30 achieves ultra-low power operation with 66 μA/MHz active current and only 0.60 μA in STOP mode (RTC + LVD active). Its SNOOZE mode allows selected peripherals (e.g., UART, ADC) to operate autonomously while the CPU remains halted, reducing average system power by up to 70% in duty-cycled sensor applications - extending CR2032 battery life beyond 10 years.

Which communication interfaces does the R5F104BGGFP#30 support, and are they LIN-bus compliant?

The R5F104BGGFP#30 supports three UART channels (with UART2 explicitly supporting LIN-bus protocol per ISO 17987), four I²C channels (including simplified I²C), and up to eight CSI channels (SPI-compatible). UART2 includes LIN-specific features such as automatic sync-break detection, checksum calculation, and wakeup-on-header - enabling direct connection to automotive and industrial LIN networks without external transceivers.
