Overview
R5F104GDANA#20 from Renesas is a 32-bit RL78/G14 microcontroller with 32 KB flash memory, 4 KB data flash, and 4 KB RAM, operating at 32 MHz (44 DMIPS), supporting ultra-low-power modes (0.60 μA in RTC+LVD mode) for industrial applications up to +105°C. It integrates UART, I²C, SPI, 10-bit ADC (8 channels), 16-bit timers, RTC, and on-chip debug.
For engineers reviewing the R5F104GDANA#20 datasheet, R5F104GDANA#20 pinout, R5F104GDANA#20 application, or R5F104GDANA#20 equivalent, key selection criteria include its HWQFN-32 package, industrial temperature grade (G), 32 KB flash capacity, integrated voltage detector (LVD) with 14-level selection, and support for background data flash rewriting.
Technical Context
The R5F104GDANA#20 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs @ 32 MHz to 30.5 µs @ 32.768 kHz). It supports multiply/divide/accumulate instructions and 1 MB address space.

FAQ
What is the maximum operating frequency and power consumption of the R5F104GDANA#20?
The R5F104GDANA#20 operates at up to 32 MHz (44 DMIPS) with active current of 66 μA/MHz. In STOP mode with only RTC and LVD enabled, it consumes 0.60 μA typical. Its 1.6–5.5 V supply range and ±1.0% on-chip oscillator accuracy support stable operation across industrial temperature extremes (-40°C to +105°C).
Does the R5F104GDANA#20 support in-system programming and secure firmware updates?
Yes, the R5F104GDANA#20 supports full in-system programming via on-chip debug interface, including boot swapping and flash shield window protection. Its 4 KB data flash enables background rewriting (BGO) while executing code from main flash, allowing secure field updates without halting application logic.
What analog peripherals are integrated into the R5F104GDANA#20?
The R5F104GDANA#20 integrates a 10-bit ADC with 8 input channels, internal 1.45 V reference voltage, and on-die temperature sensor. It also includes an 8-bit D/A converter with up to two outputs (0 V to VDD), and up to two comparators with selectable internal/external reference and window mode operation.
How does the Event Link Controller (ELC) enhance real-time performance in the R5F104GDANA#20?
The ELC in the R5F104GDANA#20 enables direct hardware linking of 19–26 peripheral events (e.g., ADC end-of-conversion → DTC trigger → timer reload), eliminating CPU intervention and interrupt latency. This achieves sub-microsecond deterministic response for time-critical control loops and synchronized signal processing.
What package and pin count does the R5F104GDANA#20 use, and what are its layout requirements?
The R5F104GDANA#20 uses a 32-pin HWQFN package (5 × 5 mm, 0.5 mm pitch) with an exposed die pad. The pad must be connected to VSS for thermal and electrical stability. REGC requires a 0.47–1 µF capacitor to VSS. Pin functions are multiplexed and configured via PIOR0/1 registers per the datasheet.
