Product details
Overview
R5F100GCDFB#V0 from Renesas is a 48-pin LFQFP-48, 128 KB flash, 8 KB data flash, 12 KB RAM RL78/G13 16-bit microcontroller operating from 1.6 V to 5.5 V, delivering 41 DMIPS at 32 MHz with ultra-low-power modes (66 μA/MHz active, 0.57 μA RTC+LVD), used in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100GCDFB#V0 datasheet, R5F100GCDFB#V0 pinout, R5F100GCDFB#V0 application, or R5F100GCDFB#V0 equivalent, key selection criteria include its integrated RTC with calendar support, 26-channel 10-bit ADC, dual UART/LIN capability, and industrial-grade temperature range (–40°C to +105°C) under G-grade qualification.
Technical Context
The R5F100GCDFB#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, real-time clock with alarm/calendar, and watchdog timer with dedicated low-speed oscillator.
Its peripheral set includes up to 16 channels of 16-bit timer, 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN interfaces, and 2–8 CSI (SPI-compatible) channels - all configurable via on-chip SFRs without external glue logic.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100GCDFB#V0?
The R5F100GCDFB#V0 operates at up to 32 MHz with an on-chip high-speed oscillator, achieving 41 DMIPS (Dhrystone MIPS) performance. This metric reflects real-world integer processing throughput under typical compiler-optimized code, validated per Renesas R01DS0131EJ0380 Rev.3.80 test conditions at 32 MHz and 3.3 V supply.
Does the R5F100GCDFB#V0 support LIN bus communication, and how is it implemented?
Yes, the R5F100GCDFB#V0 supports LIN 2.2-compliant communication via its UART peripherals. Each UART channel includes dedicated LIN hardware features: automatic break detection, sync field generation, and checksum calculation - enabling direct connection to LIN transceivers without software bit-banging or external protocol accelerators.
What are the data flash endurance and voltage requirements for rewriting the R5F100GCDFB#V0?
The R5F100GCDFB#V0 provides 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) with operation supported across the full VDD range of 1.8 V to 5.5 V. Rewrites can be performed in background operation (BGO) while executing code from program flash, ensuring deterministic real-time behavior during firmware updates or parameter logging.
How does the R5F100GCDFB#V0 achieve ultra-low power consumption in STOP mode?
The R5F100GCDFB#V0 achieves 0.57 μA STOP mode current by powering down the CPU, flash, and most peripherals while retaining operation of the real-time clock (RTC) and low-voltage detector (LVD) from a dedicated low-frequency subsystem clock (32.768 kHz). This enables timekeeping and brown-out monitoring with minimal energy draw - critical for decade-long battery operation.
Is the R5F100GCDFB#V0 pin-compatible with other RL78/G13 variants in the same LFQFP-48 package?
Yes, all RL78/G13 devices in the LFQFP-48 package (e.g., R5F100GCDFB#V0, R5F100GKDFB#V0, R5F101GCDFB#V0) share identical pinouts and electrical characteristics. Functional differences (e.g., flash size, data flash presence) do not affect pin mapping, allowing drop-in replacement within the same memory/peripheral configuration family.
