Product details
Overview
R5F100EDANA#20 from Renesas is a 40-pin HWQFN-packaged 16-bit RL78/G13 microcontroller with 64 KB flash, 4 KB data flash, and 2 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), and real-time clock - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100EDANA#20 datasheet, R5F100EDANA#20 pinout, R5F100EDANA#20 application, or R5F100EDANA#20 equivalent, key selection criteria include its 40-pin HWQFN-0.5mm-pitch package, industrial-grade −40°C to +85°C operation (D-grade), on-chip debug support, background data flash rewriting (BGO), and 16-bit RL78 CPU core with 3-stage pipeline and 1 MB address space.
Technical Context
The R5F100EDANA#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 integrates a high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz) and supports multiple low-power modes including STOP (0.57 μA with RTC+LVD active) and SNOOZE for peripheral-triggered wake-up without CPU intervention.
Peripheral integration includes dual UART/LIN interfaces, up to 10 I²C channels, 8–16 × 16-bit timers, 12-bit interval timer, calendar-based RTC with alarm/correction, 2–4-channel DMA, and 16×16-bit multiply-accumulate unit - all operating across the full 1.6–5.5 V supply range and qualified for industrial ambient temperatures.

FAQ
What is the operating temperature range for the R5F100EDANA#20?
The R5F100EDANA#20 is rated for industrial operation from −40°C to +85°C (D-grade), verified per Renesas' qualification standards. This range covers factory automation, building controls, and outdoor sensor deployments where ambient conditions exceed commercial-grade limits. The device maintains full functionality-including ADC accuracy, RTC stability, and flash write endurance-across this entire span.
Does the R5F100EDANA#20 support in-system programming via standard interfaces?
Yes, the R5F100EDANA#20 supports in-system programming using the on-chip debug interface via dedicated TOOLRxD/TOOLTxD pins (shared with UART0). Renesas-provided Flash Development Toolkit (FDT) and compatible third-party programmers enable full flash erase/write/verify without removing the R5F100EDANA#20 from the target board.
Can the R5F100EDANA#20 operate reliably at 1.6 V supply voltage?
Yes, the R5F100EDANA#20 is fully specified down to 1.6 V across its entire operating frequency range (DC to 32 MHz). At 1.6 V, it delivers 41 DMIPS performance with guaranteed timing margins, enabling direct integration into single-cell Li-ion or multi-cell alkaline systems without intermediate regulation.
How many ADC input channels does the R5F100EDANA#20 support, and what is the resolution?
The R5F100EDANA#20 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It includes dedicated AVREFP/AVREFM pins for precision ratiometric measurement and an internal 1.45 V reference usable when HS mode is selected - supporting accurate sensor signal conditioning without external references.
Is the R5F100EDANA#20 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 40-pin HWQFN package (e.g., R5F100EAANA#20 through R5F100EHANA#20) share identical pinouts and electrical characteristics. This enables drop-in replacement across memory variants - allowing hardware reuse when scaling flash, RAM, or data flash capacity without PCB redesign.
