Product details
Overview
R5F100EADNA#U0 from Renesas is a 40-pin HWQFN-packaged RL78/G13 16-bit microcontroller with 64 KB flash, 4 KB data flash, 2 KB RAM, 10-bit ADC (26 channels), and real-time clock - designed for battery-powered industrial sensors and low-power HMI control requiring <0.57 μA STOP mode current and 1.6–5.5 V operation.
For engineers reviewing the R5F100EADNA#U0 datasheet, R5F100EADNA#U0 pinout, R5F100EADNA#U0 application, or R5F100EADNA#U0 equivalent, key selection criteria include its 40-pin HWQFN-0.5 mm pitch package, integrated LVD with 14-level detection, background data flash rewriting (1M write cycles), and support for SNOOZE mode wake-up via UART/LIN or timer events.
Technical Context
The R5F100EADNA#U0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock), and features dual-clock domains enabling simultaneous high-speed processing and ultra-low-power RTC/LVD operation.
It integrates a 2-channel DMA controller (2-cycle transfers between SFR and RAM), 16×16→32-bit multiplier/accumulator, and multiple serial interfaces including CSI (SPI-compatible), UART/LIN, and I²C - all configurable independently of CPU activity to reduce active time in sensor polling or communication tasks.

What is the maximum operating frequency and corresponding current consumption of the R5F100EADNA#U0?
The R5F100EADNA#U0 operates up to 32 MHz using its high-speed on-chip oscillator. At this frequency, typical active current is 66 μA per MHz (2.112 mA total), measured at VDD = 3.3 V and TA = 25°C. This value scales linearly with clock speed, enabling precise power budgeting for dynamic frequency scaling strategies.
Does the R5F100EADNA#U0 support in-system programming via its UART interface?
Yes, the R5F100EADNA#U0 supports bootloader-based in-system programming via UART using the built-in on-chip debug function.

The R5F100EADNA#U0 provides 26 analog input channels for its 10-bit ADC. Reference options include external AVREFP/AVREFM pins, internal 1.45 V reference, or VDD as reference - all selectable via register configuration. The internal temperature sensor is also accessible as an ADC input channel.
Can the R5F100EADNA#U0 retain RTC and LVD functionality while in STOP mode?
Yes, the R5F100EADNA#U0 maintains full RTC calendar, alarm, and clock correction functions along with LVD monitoring and interrupt generation while in STOP mode, drawing only 0.57 μA typical. This enables time-stamped event logging and supply supervision without waking the CPU.
What packaging and lead finish does the R5F100EADNA#U0 use, and is it RoHS compliant?
The R5F100EADNA#U0 uses a 40-pin HWQFN package (6 × 6 mm, 0.5-mm pitch) with an exposed thermal pad and matte tin lead finish. It is fully RoHS compliant (Pb-free), meets JEDEC J-STD-020 moisture sensitivity level 3, and is qualified for industrial temperature range (–40°C to +85°C).
