Renesas R5F100GDANA#20

Overview

R5F100GDANA#20 from Renesas is a 48-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating from 1.6–5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power modes (0.57 μA RTC+LVD), 10-bit ADC (26 channels), RTC, UART, I²C, SPI, and 16-bit timers for industrial control and sensor interface applications.

For engineers reviewing the R5F100GDANA#20 datasheet, R5F100GDANA#20 pinout, R5F100GDANA#20 application, or R5F100GDANA#20 equivalent, key selection criteria include its industrial-grade temperature range (−40°C to +105°C), integrated data flash with 1M rewrite cycles, background operation during program execution, and hardware-accelerated multiply-accumulate for real-time signal processing.

Technical Context

The R5F100GDANA#20 implements the RL78 CPU core with a 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 subsystem clock). It integrates a 12-bit interval timer, calendar-based real-time clock with alarm and correction, and a watchdog timer powered by a dedicated low-speed on-chip oscillator.

Its peripheral set includes up to 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, 3–10-channel I²C/Simplified I²C, 2–4-channel UART/LIN, 2–8-channel CSI (SPI-compatible), and DMA controller with 2/4 channels enabling zero-wait-state transfers between SFR and RAM in just two clocks.

FAQ

What is the maximum operating frequency and performance of the R5F100GDANA#20?

The R5F100GDANA#20 operates at up to 32 MHz with a peak performance of 41 DMIPS. Its high-speed on-chip oscillator supports frequencies from 1 to 32 MHz with ±1.0% accuracy across 1.8–5.5 V and −20°C to +85°C. The RL78 core achieves 0.03125 μs minimum instruction execution time in high-speed mode, enabling deterministic real-time response for control loops and communication stacks.

Does the R5F100GDANA#20 include integrated data flash memory, and what are its endurance specifications?

Yes, the R5F100GDANA#20 includes 8 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. It supports background operation (BGO), allowing program execution from code flash while simultaneously rewriting data flash-essential for reliable firmware parameter storage and event logging without halting application code.

What low-power modes does the R5F100GDANA#20 support, and what is its lowest current consumption?

The R5F100GDANA#20 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it consumes just 0.57 μA (typical) at VDD = 3.0 V and TA = 25°C. This ultra-low quiescent current enables multi-year operation on coin-cell batteries in sensor and metering applications, with fast wake-up (<;10 μs) from external interrupts or RTC alarms.

How many analog input channels and what resolution does the ADC in the R5F100GDANA#20 provide?

The R5F100GDANA#20 features a 10-bit successive-approximation ADC with up to 26 analog input channels. It includes an internal 1.45 V reference voltage and an integrated temperature sensor. The ADC operates across the full 1.6–5.5 V supply range and supports simultaneous sampling with hardware triggers from timers or peripherals-ideal for multi-sensor monitoring systems.

Is the R5F100GDANA#20 qualified for industrial temperature operation, and what is its specified range?

Yes, the R5F100GDANA#20 carries the 'G' suffix denoting industrial temperature qualification, with a guaranteed operating ambient temperature range of −40°C to +105°C. This rating is validated per Renesas' industrial-grade screening and testing standards, making the R5F100GDANA#20 suitable for deployment in harsh environments such as factory floors, outdoor infrastructure, and enclosed motor drives.
