Product details
Overview
R5F104GDANA#W0 from Renesas is a 48-pin HWQFN-packaged RL78/G14 16-bit microcontroller designed for ultra-low-power industrial applications. It features 32 KB flash memory, 4 KB data flash, 4 KB RAM, 1.6–5.5 V operation, -40 to +105°C temperature range (G-grade), and delivers 44 DMIPS at 32 MHz for embedded control in battery-powered sensors and motor drives.
For engineers reviewing the R5F104GDANA#W0 datasheet, R5F104GDANA#W0 pinout, R5F104GDANA#W0 application, or R5F104GDANA#W0 equivalent, key selection criteria include its industrial-grade thermal rating, integrated RTC with calendar function, hardware DTC/ELC for deterministic peripheral coordination, and support for LIN-bus UART communication in compact 7×7 mm HWQFN packaging.
Technical Context
The R5F104GDANA#W0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, enabling instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). It integrates a high-accuracy ±1.0% on-chip oscillator (selectable 1–64 MHz), power management with HALT/STOP/SNOOZE modes (0.60 μA RTC+LVD standby), and dedicated low-speed oscillator for watchdog timer.
Peripheral subsystems include 8-channel 16-bit Timer Array Unit (TAU), 12-bit interval timer, real-time clock with alarm/calendar, 10-bit 16-channel ADC with internal 1.45 V reference and temperature sensor, two 8-bit DAC channels, and up to 10 I²C/Simplified I²C interfaces - all accessible via configurable I/O redirection registers (PIOR0/1).

FAQ
What is the operating temperature range certified for R5F104GDANA#W0?
The R5F104GDANA#W0 is rated for -40 to +105°C ambient operation (G-grade), making it suitable for under-hood automotive modules and industrial equipment exposed to elevated thermal stress. This specification is validated per Renesas' industrial qualification standards and applies to the full 48-pin HWQFN package configuration.
Does R5F104GDANA#W0 support hardware LIN bus communication?
Yes, R5F104GDANA#W0 supports LIN 2.2-compliant communication through its UART peripherals (channels 0–2), which include dedicated LIN-break detection, sync byte handling, and checksum generation. No external LIN transceiver is required when paired with a compliant physical layer driver.
What is the maximum ADC resolution and channel count supported by R5F104GDANA#W0?
R5F104GDANA#W0 integrates a 10-bit successive-approximation ADC with up to 16 input channels (ANI0–ANI15), including dedicated AVREFP/AVREFM pins for differential reference. It also provides an internal 1.45 V reference and on-die temperature sensor for self-calibration.
Can R5F104GDANA#W0 execute code while rewriting data flash memory?
Yes, R5F104GDANA#W0 supports Background Operation (BGO) for data flash memory, allowing CPU instructions to execute from program memory concurrently with data flash erase/write cycles - essential for logging sensor data without interrupting real-time control loops.
What debug interface does R5F104GDANA#W0 use, and how is it connected?
R5F104GDANA#W0 uses the on-chip debug interface accessed via pins P50 (TOOLRxD) and P51 (TOOLTxD), which share functionality with UART0. A standard 3.3 V USB-to-serial adapter with TTL logic levels connects directly to these pins for programming and real-time debugging using Renesas CS+ or e2 studio IDE.
