Product details
Overview
R5F100FDGFP#10 from Renesas is a 44-pin LQFP-44, 32 MHz RL78/G13 16-bit 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 integrates 12-bit RTC, 10-bit 24-channel ADC, UART/LIN, I²C, CSI, 16-bit timers, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD).
For engineers reviewing the R5F100FDGFP#10 datasheet, R5F100FDGFP#10 pinout, R5F100FDGFP#10 application, or R5F100FDGFP#10 equivalent, key selection criteria include industrial-grade thermal rating, integrated LIN bus support for automotive body electronics, on-chip data flash endurance (1M rewrite cycles), and HALT/STOP/SNOOZE power states for battery-powered sensor nodes.
Technical Context
The R5F100FDGFP#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 subsystem clock). Its memory architecture includes separate code flash (96 KB, 1 KB block erase), data flash (8 KB, background operation enabled), and SRAM (8 KB), all accessible within a 1 MB address space.
Peripheral integration targets embedded control with real-time constraints: dual UART channels (one with LIN physical layer compliance), up to 10 I²C/Simplified I²C interfaces, 8–16 × 16-bit timers, and hardware DMA (4 channels) enabling zero-cycle CPU intervention for memory-to-peripheral transfers.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100FDGFP#10?
The R5F100FDGFP#10 operates at up to 32 MHz using its high-speed on-chip oscillator (±1.0% accuracy), delivering 41 DMIPS of processing performance. Its RL78 core achieves minimum instruction execution times of 0.03125 μs in high-speed mode, confirmed in the R01DS0131EJ0380 datasheet Section 1.1.
Does the R5F100FDGFP#10 support LIN communication, and how is it implemented?
Yes, the R5F100FDGFP#10 supports LIN communication via its UART peripheral with built-in LIN physical layer compliance (SAE J2602). No external transceiver is required - the UART modulates the signal directly on P12/TxD0, and the device meets LIN bus electrical specifications per datasheet Section 1.1 Serial Interface.
What are the data flash endurance and voltage requirements for rewriting the R5F100FDGFP#10?
The R5F100FDGFP#10 provides 8 KB of data flash rated for 1,000,000 rewrite cycles (typical) at VDD = 1.8 V to 5.5 V. Background operation (BGO) allows program execution from code flash during data flash writes, as specified in Section 1.1 Data Flash Memory of the R01DS0131EJ0380 datasheet.
What industrial temperature grade does the R5F100FDGFP#10 support, and what packaging is used?
The R5F100FDGFP#10 is rated for -40°C to +105°C (G-grade industrial), packaged in a 44-pin LQFP (10 × 10 mm, 0.8 mm pitch) with lead finish matte tin, per the ordering code suffix "G" and package code "FP" defined in Figure 1-1 of R01DS0131EJ0380.
How does the R5F100FDGFP#10 achieve ultra-low-power operation in STOP mode?
The R5F100FDGFP#10 achieves 0.57 μA typical current consumption in STOP mode by disabling the main system clock while retaining power to the real-time clock (RTC) and low-voltage detector (LVD). This configuration is explicitly documented in Section 1.1 Features under "Ultra-low power consumption technology" of R01DS0131EJ0380.
