It integrates UART, I²C, SPI, timers, RTC, and on-chip debug for compact industrial sensor nodes and battery-powered control systems.

For engineers reviewing the R5F10EBCANA#40 datasheet, R5F10EBCANA#40 pinout, R5F10EBCANA#40 application, or R5F10EBCANA#40 equivalent, key selection criteria include its 32-pin HWQFN (5 × 5 mm) package, 1.6–3.6 V supply range, 32 MHz max CPU frequency (41 DMIPS), and support for 18-channel analog acquisition with internal voltage reference and temperature sensor.

Technical Context

The R5F10EBCANA#40 implements the RL78 16-bit CISC Harvard architecture with 3-stage pipeline, enabling 86% of instructions in 1–2 clock cycles. Its low-power design includes multiple sleep modes-Stop (0.23 µA), Halt (0.57 µA), and Snooze (0.6 mA for ADC)-and a high-speed on-chip oscillator with ±1% accuracy across 1.8–3.6 V and −20°C to +85°C.

It features dual power domains (VDD/EVDD0, VSS/EVSS0), peripheral I/O redirection via PIOR register, and safety functions including RAM parity check, flash CRC, illegal access detection, and clock/frequency monitoring compliant with IEC/UL 60730.

FAQ

What is the maximum operating frequency and performance of the R5F10EBCANA#40?

The R5F10EBCANA#40 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its RL78 16-bit core executes 86% of instructions in just 1–2 clock cycles, and the 3-stage pipeline ensures deterministic timing for real-time control tasks. The R5F10EBCANA#40 achieves this while maintaining ultra-low active current consumption of 66 µA/MHz.

Does the R5F10EBCANA#40 support hardware debugging without external tools?

Yes, the R5F10EBCANA#40 includes a 1-wire on-chip debug function accessible via the TOOL0 pin (P40), eliminating the need for external JTAG or SWD debug probes. This enables full program download, breakpoint setting, and real-time variable inspection directly through a single I/O pin, reducing BOM cost and board space in space-constrained designs using the R5F10EBCANA#40.

How many analog input channels does the R5F10EBCANA#40 support, and what ADC resolution is provided?

The R5F10EBCANA#40 supports 18 analog input channels with a 12-bit successive approximation ADC. Conversion time is 3.375 µs per sample, and the ADC operates down to 1.6 V supply. It includes internal voltage reference (1.45 V), AVREFP/AVREFM inputs, and an on-chip temperature sensor-enabling accurate, self-referenced measurements without external components in the R5F10EBCANA#40 design.

What low-power modes are available on the R5F10EBCANA#40, and what are their typical current draws?

The R5F10EBCANA#40 offers Stop mode (0.23 µA, RAM retained), Halt mode (0.57 µA with RTC + LVD enabled), and Snooze mode (0.6 mA for ADC, 0.7 mA for UART). These modes are controlled via software and support fast wake-up times. The R5F10EBCANA#40's ultra-low-power architecture makes it ideal for applications requiring multi-year battery life, such as wireless sensor nodes and portable instrumentation.

Can the R5F10EBCANA#40 operate without an external crystal oscillator?

Yes, the R5F10EBCANA#40 can operate entirely from its high-speed on-chip oscillator, which runs from 1 MHz to 32 MHz with ±1% accuracy across 1.8–3.6 V and −20°C to +85°C. Pre-configured settings include 32, 24, 16, 12, 8, 6, 4, 3, 2, and 1 MHz-allowing immediate system startup without crystal load capacitors or layout constraints. This capability simplifies design and reduces cost in the R5F10EBCANA#40 implementation.
