Product details
Overview
R5F100GKANA#20 from Renesas is a 48-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 256 KB flash, 8 KB data flash, and 20 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 (26 channels), UART/SPI/I²C interfaces, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD) for battery-powered industrial control and sensor nodes.
For engineers reviewing the R5F100GKANA#20 datasheet, R5F100GKANA#20 pinout, R5F100GKANA#20 application, or R5F100GKANA#20 equivalent, key selection criteria include its industrial-grade temperature rating, on-chip data flash endurance (1M rewrite cycles), background operation capability during flash reprogramming, and hardware-accelerated multiply-accumulate unit for real-time signal processing.
Technical Context
The R5F100GKANA#20 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its memory subsystem includes 256 KB code flash (1 KB block size), 8 KB data flash with background operation (BGO), and 20 KB SRAM - enabling concurrent execution and non-volatile data logging.
Peripherals include up to 16× 16-bit timers, 1× real-time clock with calendar/alarm, 1× watchdog timer, 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, and multi-protocol serial interfaces: 2–4 UART/LIN, 2–8 CSI (SPI-compatible), and 3–10 I²C channels - all configurable for mixed-signal industrial edge node applications.

The R5F100GKANA#20 operates at up to 32 MHz with a measured performance of 41 DMIPS. This rating is achieved using the RL78 CPU core's 3-stage pipeline and high-speed on-chip oscillator calibrated to ±1.0% accuracy across 1.8–5.5 V and -20°C to +85°C - ensuring deterministic timing in real-time control loops without external crystal dependency.
Does the R5F100GKANA#20 support in-system programming and secure firmware updates?
Yes, the R5F100GKANA#20 supports full in-system programming via on-chip debug interface and includes flash shield window functionality to define protected memory regions. Its data flash supports background operation (BGO), allowing application code to run from program memory while rewriting data flash - enabling secure, seamless firmware updates without system interruption.
What are the key low-power modes available on the R5F100GKANA#20 and their typical current consumption?
The R5F100GKANA#20 offers HALT (66 μA/MHz), STOP (0.57 μA with RTC + LVD active), and SNOOZE modes. STOP mode maintains RTC calendar, alarm, and voltage monitoring functions while disabling CPU and most peripherals - making it ideal for battery-backed applications like utility meters where decade-scale operation is required.
How many analog input channels does the R5F100GKANA#20 support, and what ADC resolution and reference options are available?
The R5F100GKANA#20 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It supports both external differential reference (AVREFP/AVREFM) and internal 1.45 V reference, and includes an on-die temperature sensor usable as a system health monitor - all accessible without external components.
Is the R5F100GKANA#20 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100GKANA#20 is pin-compatible with all 48-pin HWQFN RL78/G13 variants (e.g., R5F100FKANA#20, R5F100JKANA#20), sharing identical pinout, electrical characteristics, and peripheral mapping. This enables scalable design reuse across memory configurations while maintaining PCB layout compatibility.
