Overview

R5F100FJGFP#30 from Renesas is a 44-pin LQFP-packaged 16-bit RL78/G13 microcontroller with 96 KB flash, 8 KB data flash, and 8 KB RAM, operating from 1.6 V to 5.5 V across –40°C to +105°C industrial temperature range. It delivers 41 DMIPS at 32 MHz, integrates RTC, 10-bit ADC (24 channels), UART/LIN, I²C, and CSI interfaces, and targets low-power industrial control and sensor node applications.

For engineers reviewing the R5F100FJGFP#30 datasheet, R5F100FJGFP#30 pinout, R5F100FJGFP#30 application, or R5F100FJGFP#30 equivalent, key selection criteria include its industrial-grade temperature rating (–40°C to +105°C), integrated LIN-capable UART for automotive body electronics, background data flash rewrite capability, ultra-low power STOP mode (0.57 μA), and 44-pin LQFP package with 24-channel analog input support.

Technical Context

The R5F100FJGFP#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction execution time from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It features dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, selectable 1–32 MHz) and dedicated low-speed oscillator for watchdog and RTC.

Its peripheral set includes 2–4 channel DMA, 16-bit timer array (12 channels), real-time clock with calendar/alarm/correction, 10-bit ADC with internal 1.45 V reference and temperature sensor, and multi-protocol serial interfaces - including UART with LIN bus support, up to 10-channel simplified I²C, and 2–8-channel CSI (SPI-compatible).

FAQ

What is the maximum operating frequency and corresponding performance of the R5F100FJGFP#30?

The R5F100FJGFP#30 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs in this mode, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation with 30.5 μs instruction time. This flexibility allows designers to balance performance and power across application states.

Does the R5F100FJGFP#30 support LIN bus communication, and how is it implemented?

Yes, the R5F100FJGFP#30 supports LIN bus communication through its UART peripheral, which includes hardware features compliant with LIN 2.2 and SAE J2602 standards. It provides automatic sync-break detection, checksum generation (classic and enhanced), and configurable baud rates. The UART operates independently of the main CPU clock, ensuring timing accuracy even during low-power modes - a key requirement for automotive body electronics.

What are the memory resources available on the R5F100FJGFP#30, and how is data flash utilized?

The R5F100FJGFP#30 integrates 96 KB of code flash memory and 8 KB of dedicated data flash memory. The data flash supports background operation (BGO), allowing program execution from code flash while rewriting data flash - essential for firmware updates or parameter storage without halting system operation. It is rated for 1,000,000 write cycles at VDD = 1.8–5.5 V and includes flash shield window and block erase prohibition for security-critical applications.

How does the R5F100FJGFP#30 achieve ultra-low power consumption in STOP mode?

The R5F100FJGFP#30 achieves 0.57 μA typical current draw in STOP mode by powering down the CPU core, flash memory, and most peripherals while retaining operation of the real-time clock (RTC), low-voltage detector (LVD), and RAM contents. The dedicated low-speed on-chip oscillator (32.768 kHz) sustains RTC functionality, and wake-up can occur via external interrupt, RTC alarm, or LVD event - all within microseconds, making it ideal for energy-harvesting and long-life battery applications.

What analog capabilities does the R5F100FJGFP#30 provide, and are they calibrated?

The R5F100FJGFP#30 features a 10-bit successive-approximation ADC with up to 24 analog input channels, internal 1.45 V reference voltage, and an integrated temperature sensor. The temperature sensor is factory-calibrated across the –40°C to +105°C range with ±2.5°C accuracy, and the ADC supports simultaneous sampling with hardware averaging to improve noise immunity. These capabilities enable direct implementation of thermal monitoring, battery voltage supervision, and multi-sensor data acquisition without external signal conditioning.
