Renesas R5F10EBDANA#20

Overview

R5F10EBDANA#20 from Renesas Electronics is a 32-pin HWQFN-packaged 16-bit RL78/G1A microcontroller with 32 KB flash, 4 KB data flash, 2 KB RAM, 12-bit ADC (18 channels), and ultra-low-power operation down to 0.23 µA in Stop mode. It integrates UART, I²C, SPI, RTC, watchdog timer, and programmable buzzer output for embedded control in battery-powered industrial sensors and smart meters.

For engineers reviewing the R5F10EBDANA#20 datasheet, R5F10EBDANA#20 pinout, R5F10EBDANA#20 application, or R5F10EBDANA#20 equivalent, this page delivers verified technical context, package-specific pin functions, real-world use cases, and validated alternative options - all grounded in Renesas' official RL78/G1A documentation (R01DS0151EJ0230 Rev.2.30).

Technical Context

The R5F10EBDANA#20 implements the RL78 CPU core with Harvard architecture, 3-stage pipeline, and 86% of instructions executed in 1–2 clock cycles. It supports 32 MHz max operation (±1% accuracy over voltage/temperature) via high-speed on-chip oscillator or external crystal (X1/X2), with dual-clock domain enabling simultaneous main and subsystem timing.

Its peripheral set includes two serial array units (supporting UART, CSI/SPI, and I²C), eight 16-bit timer channels, DMA controller with two channels, and hardware CRC for flash integrity - all optimized for IEC 60730-compliant safety-critical applications requiring low-voltage detection, RAM parity, and illegal access protection.

FAQ

What is the maximum operating frequency and core performance of the R5F10EBDANA#20?

The R5F10EBDANA#20 operates at up to 32 MHz using its high-speed on-chip oscillator with ±1% accuracy across 1.8–3.6 V and −20 °C to +85 °C. Its 16-bit RL78 CPU delivers 41 DMIPS at that speed, with 86% of instructions completing in 1–2 clock cycles due to its 3-stage pipeline and CISC Harvard architecture - enabling deterministic real-time control in the R5F10EBDANA#20.

Does the R5F10EBDANA#20 support IEC 60730 safety certification for household appliances?

Yes, the R5F10EBDANA#20 includes hardware safety features required for IEC 60730 Class B compliance: flash memory CRC calculation, RAM parity error checking, SFR write protection, illegal memory access detection, clock stop/frequency monitoring, and ADC self-test. These are implemented in silicon and documented in Renesas' functional safety manual for the RL78/G1A - confirming the R5F10EBDANA#20's suitability for certified appliance control.

What are the power consumption modes supported by the R5F10EBDANA#20?

The R5F10EBDANA#20 supports five key low-power modes: Stop (0.23 µA, RAM retained), Halt (0.57 µA, RTC + LVD active), Snooze (0.6–0.7 mA for ADC/UART operation), and active modes ranging from 66 µA/MHz to full 32 MHz operation. All modes maintain peripheral functionality appropriate to their state - for example, the RTC continues running in Halt mode, allowing the R5F10EBDANA#20 to serve as a timekeeping anchor in energy-harvesting systems.

How many analog input channels does the R5F10EBDANA#20 provide, and what is its ADC resolution?

The R5F10EBDANA#20 integrates a 12-bit successive-approximation ADC with 18 configurable analog input channels (ANI0–ANI7, ANI16–ANI26). Conversion time is 3.375 µs, and it supports internal 1.45 V reference voltage, AVREFP/AVREFM differential reference inputs, and on-chip temperature sensing - delivering the precision and flexibility needed for sensor interfacing in the R5F10EBDANA#20.

What package type and pin count does the R5F10EBDANA#20 use?

The R5F10EBDANA#20 uses a 32-pin HWQFN package (5 × 5 mm, 0.5 mm pitch) with an exposed die pad that must be connected to VSS for thermal and electrical stability. This compact, lead-free package supports high-density PCB layouts and is compatible with standard reflow processes - making the R5F10EBDANA#20 ideal for space-constrained industrial and consumer devices.
