Renesas R5F104GKANA#W0

Overview

R5F104GKANA#W0 from Renesas is a 48-pin HWQFN-packaged RL78/G14 16-bit microcontroller with 256 KB flash, 8 KB data flash, and 24 KB RAM, operating at 1.6–5.5 V and supporting -40°C to +105°C industrial temperature range (G-grade). It delivers 44 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates UART, I²C, CSI, 16-bit timers, 10-bit ADC (20 ch), and real-time clock for embedded control in battery-powered and thermally constrained systems.

For engineers reviewing the R5F104GKANA#W0 datasheet, R5F104GKANA#W0 pinout, R5F104GKANA#W0 application, or R5F104GKANA#W0 equivalent, key selection criteria include its G-grade extended temperature rating, HWQFN-48 (7×7 mm, 0.5 mm pitch) package with exposed die pad, 256 KB code flash with security and self-programming, and integrated analog peripherals enabling single-chip sensor interface and motor control in industrial IoT edge nodes.

Technical Context

The R5F104GKANA#W0 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-power mode). It includes on-chip high-accuracy ±1.0% oscillator (1–64 MHz selectable) and dedicated low-speed oscillator for watchdog timer operation.

Peripheral integration centers on event-driven efficiency: the Event Link Controller (ELC) enables direct hardware linking of 19–26 event sources to peripheral functions without CPU intervention, while the Data Transfer Controller (DTC) supports background data flash rewriting via BGO during program execution - critical for firmware updates and parameter storage in field-deployed devices.

FAQ

What is the maximum operating frequency and corresponding DMIPS rating for the R5F104GKANA#W0?

The R5F104GKANA#W0 operates at a maximum frequency of 32 MHz and delivers 44 DMIPS (Dhrystone MIPS) performance. This metric reflects its real-world computational throughput for typical embedded control code, validated under standard conditions using the RL78 core's 3-stage pipeline and optimized compiler toolchain. The R5F104GKANA#W0 achieves this performance while maintaining ultra-low active current consumption of 66 μA/MHz.

Does the R5F104GKANA#W0 support self-programming of its code flash memory?

Yes, the R5F104GKANA#W0 supports full self-programming of its 256 KB code flash memory, including boot swap functionality and flash shield window protection. This capability enables secure in-field firmware updates and bootloader implementations without external programming hardware. The flash library uses designated RAM areas (start address F9F00H for R5F104xJ variants) and requires proper initialization per Renesas Application Note R20UT2944.

What is the analog reference voltage source for the 10-bit ADC in the R5F104GKANA#W0?

The R5F104GKANA#W0's 10-bit ADC supports both internal and external reference voltage sources. Its internal reference is a factory-trimmed 1.45 V bandgap voltage, usable across the full 1.6–5.5 V supply range. External references can be applied via AVREFP and AVREFM pins, enabling ratiometric measurements with precision external references or direct connection to sensor bridges.

How many UART, I²C, and CSI interfaces does the R5F104GKANA#W0 integrate?

The R5F104GKANA#W0 integrates three UART channels (supporting LIN bus), up to ten I²C/simplified I²C channels, and three to eight CSI (Simplified SPI) channels. Channel count depends on pin multiplexing configuration and variant-specific peripheral enablement; all are accessible on the 48-pin HWQFN package via dedicated or remappable pins controlled by the Peripheral I/O Redirection Registers (PIOR0/1).

Is the R5F104GKANA#W0 qualified for industrial temperature operation?

Yes, the R5F104GKANA#W0 is rated for industrial temperature operation from -40°C to +105°C (G-grade). This qualification covers full electrical performance, flash endurance, and real-time clock accuracy across the entire range, making it suitable for deployment in harsh environments such as factory floors, outdoor utility meters, and automotive under-hood modules.
