Overview
R5F101GKANA#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 at 1.6–5.5 V and delivering 41 DMIPS at 32 MHz for low-power industrial control, sensor nodes, and appliance HMI applications.
For engineers reviewing the R5F101GKANA#20 datasheet, R5F101GKANA#20 pinout, R5F101GKANA#20 application, or R5F101GKANA#20 equivalent, key selection criteria include its 256 KB code flash with self-programming, real-time clock with calendar support, ultra-low power STOP mode (0.57 μA), 10-bit 26-channel ADC, and integrated LIN-capable UART interfaces.
Technical Context
The R5F101GKANA#20 implements the RL78 CPU core with CISC architecture and 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). It integrates a 12-bit interval timer, RTC with alarm/calendar, and watchdog timer using a dedicated low-speed on-chip oscillator.
It features dual serial interface sets: up to 4 UART/LIN channels and up to 10 I²C/Simplified I²C channels, alongside 8–16 16-bit timers, DMA controller with 4 channels, and hardware multiplier/divider for 16×16/32÷32 operations - all optimized for deterministic real-time response in resource-constrained embedded systems.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101GKAFP#30 | LQFP-48 package (7×7 mm, 0.5 mm pitch), identical memory and peripheral set | Requires PCB layout change due to different footprint and thermal pad configuration | Select for prototyping or where manual soldering or thermal management favors exposed-pad QFP |
| R5F101JKANA#20 | Same HWQFN-48 package but with 192 KB flash, 8 KB data flash, 16 KB RAM | Lower memory capacity suits simpler control tasks; reduced code space may limit feature-rich firmware | Select when application firmware fits within 192 KB and cost optimization is prioritized over headroom |
Compared with R5F101GKANA#20, R5F101GKAFP#30 offers identical functionality in a more serviceable LQFP package but sacrifices thermal performance and board density, while R5F101JKANA#20 provides a cost-optimized variant with 64 KB less flash and 4 KB less RAM - suitable for streamlined implementations without runtime expansion needs.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F101GKANA#20?
The R5F101GKANA#20 operates at up to 32 MHz using its high-speed on-chip oscillator and delivers 41 DMIPS (Dhrystone MIPS) at that frequency. Its minimum instruction execution time is 0.03125 μs under these conditions, verified per Renesas R01DS0131EJ0380 Rev.3.80 datasheet Section 1.1.
Does the R5F101GKANA#20 include an integrated real-time clock (RTC) with calendar functionality?
Yes, the R5F101GKANA#20 includes a dedicated real-time clock module supporting full 99-year calendar, alarm interrupt, and clock correction function. This RTC operates independently in STOP mode with only 0.57 μA current draw, enabling time-stamped logging and wake-up scheduling without external components.
What are the data flash endurance and voltage requirements for rewriting the R5F101GKANA#20?
The R5F101GKANA#20 provides 8 KB of data flash memory rated for 1,000,000 rewrite cycles (typical) with operation supported across the full VDD range of 1.8 V to 5.5 V. Background operation (BGO) allows concurrent code execution during rewrite, and the flash library reserves RAM starting at address FAF00H for this purpose.
Which communication interfaces does the R5F101GKANA#20 support for LIN bus implementation?
The R5F101GKANA#20 supports LIN bus communication via its UART channels, which are explicitly documented as LIN-bus compatible in the R01DS0131EJ0380 datasheet. At least two UART modules (e.g., UART0 and UART1) can be configured for LIN physical layer compliance per ISO 17987-4, including break detection and sync field handling.
What is the industrial temperature grade and package type of the R5F101GKANA#20?
The R5F101GKANA#20 is qualified for industrial operation from −40°C to +105°C (G-grade) and housed in a 48-pin HWQFN package (7 × 7 mm, 0.5-mm pitch) with exposed thermal pad. The "G" suffix in the part number and "#20" tape-and-reel packaging code confirm its industrial temperature and HWQFN compatibility.
