Overview
R5F100GCANA#U0 from Renesas is a 48-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, and integrated RTC, ADC, UART, I²C, and SPI interfaces - designed for ultra-low-power industrial sensor nodes and battery-powered control systems operating from 1.6 V to 5.5 V.
For engineers reviewing the R5F100GCANA#U0 datasheet, R5F100GCANA#U0 pinout, R5F100GCANA#U0 application, or R5F100GCANA#U0 equivalent, key selection criteria include its 0.57 μA STOP-mode current, 41 DMIPS @ 32 MHz performance, 10-bit 26-channel ADC, hardware LIN support, and -40°C to +105°C industrial temperature grade (G-suffix).
Technical Context
The R5F100GCANA#U0 implements the RL78 CPU core with a 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), and features a unified 1 MB address space with four register banks of eight 8-bit registers each.
It integrates dual power management modes - HALT (66 μA/MHz active current) and STOP (0.57 μA with RTC + LVD active) - alongside on-chip debug, self-programming flash with boot swap, background data flash rewriting (BGO), and 14-level voltage detector (LVD) with interrupt/reset options.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100GCANA#U0?
The R5F100GCANA#U0 operates 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 at this speed, and it supports dynamic clock switching down to 32.768 kHz for ultra-low-power RTC operation with 30.5 μs instruction time.
Does the R5F100GCANA#U0 support hardware LIN communication?
Yes, the R5F100GCANA#U0 supports hardware LIN communication through its UART peripheral, which includes dedicated LIN break detection, sync field generation, and checksum calculation - eliminating software timing constraints and ensuring compliance with LIN 2.x specifications without CPU overhead.
What are the memory resources allocated to the flash library in the R5F100GCANA#U0?
The R5F100GCANA#U0 uses RAM starting at address F7F00H for the flash self-programming library. This allocation is confirmed for all R5F100xL and R5F101xL variants in the RL78/G13 family, enabling safe in-application reprogramming of both code and data flash memory.
How does the R5F100GCANA#U0 achieve 0.57 μA STOP-mode current?
The R5F100GCANA#U0 achieves 0.57 μA STOP-mode current by disabling all clocks except the 32.768 kHz subsystem oscillator, retaining only RTC and LVD functionality in memory-retentive mode. This state preserves calendar time and enables wake-up on LVD threshold crossing or RTC alarm - critical for long-life battery applications.
Is the R5F100GCANA#U0 qualified for industrial temperature operation?
Yes, the R5F100GCANA#U0 carries the 'G' suffix indicating industrial temperature grade with guaranteed operation from -40°C to +105°C. This qualification covers all embedded peripherals including ADC, RTC, and voltage detector, making it suitable for under-hood automotive modules and factory-floor controllers.
