For engineers reviewing the R5F100EDGNA#20 datasheet, R5F100EDGNA#20 pinout, R5F100EDGNA#20 application, or R5F100EDGNA#20 equivalent, key selection criteria include its 0.57 μA RTC+LVD stop-mode current, integrated 10-bit 26-channel ADC with internal temperature sensor, and hardware UART/SPI/I²C support for embedded monitoring systems.
Technical Context
The R5F100EDGNA#20 implements the RL78 CPU core with a 3-stage CISC pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock), and includes on-chip debug, self-programming flash with boot swap, and background operation during data flash rewriting.
It integrates a 12-bit interval timer, real-time clock with calendar/alarm/correction, watchdog timer, DMA controller (2 channels), 16×16/32÷32 multiplier/divider, and configurable I/O ports including N-ch open-drain outputs with 6 V tolerance - all optimized for deterministic low-power operation in battery-backed or energy-constrained systems.

FAQ
What is the operating temperature range for the R5F100EDGNA#20?
The R5F100EDGNA#20 is rated for industrial operation from -40°C to +105°C, as indicated by the 'G' suffix in its part number. This wide range ensures reliable performance in demanding environments such as factory automation equipment, outdoor utility meters, and HVAC control units where ambient temperatures exceed standard commercial limits.
Does the R5F100EDGNA#20 include an integrated temperature sensor?
Yes, the R5F100EDGNA#20 includes an on-chip temperature sensor usable with the 10-bit ADC. It is selectable only in high-speed main mode and provides calibrated readings referenced to the internal 1.45 V bandgap voltage - enabling system-level thermal monitoring without external components or calibration overhead in the R5F100EDGNA#20 design.
What debug interface does the R5F100EDGNA#20 support?
The R5F100EDGNA#20 supports Renesas' on-chip debug interface using a 2-pin SWD (Serial Wire Debug) connection (SWDIO and SWCLK). This eliminates the need for dedicated debug headers or JTAG pins, reducing PCB footprint and simplifying development with the Renesas E2 emulator and CS+ IDE - all fully supported for the R5F100EDGNA#20.
Can the R5F100EDGNA#20 operate from a single 1.8 V supply?
Yes, the R5F100EDGNA#20 supports operation from 1.6 V to 5.5 V, including 1.8 V. At this voltage, it maintains full functionality - including 32 MHz operation (with appropriate oscillator configuration), ADC conversion (VDD as reference), and I/O drive strength - making the R5F100EDGNA#20 suitable for low-voltage battery-powered systems with regulated 1.8 V rails.
Is data flash rewriting possible while executing code from main flash on the R5F100EDGNA#20?
Yes, the R5F100EDGNA#20 supports Background Operation (BGO) for data flash. Code execution continues uninterrupted from program flash memory while the 4 KB data flash is being rewritten - critical for applications like firmware parameter updates or event logging where deterministic real-time response must be preserved in the R5F100EDGNA#20 implementation.
