FAQ

What is the maximum operating frequency and performance of the R5F10EGDGFB#V0?

The R5F10EGDGFB#V0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its RL78 CPU core executes 86% of instructions in just 1–2 clock cycles due to its 3-stage pipeline and CISC Harvard architecture - making it suitable for real-time control tasks in resource-constrained industrial systems. The R5F10EGDGFB#V0 maintains this performance across its full 1.6 V to 3.6 V supply range.

Does the R5F10EGDGFB#V0 support background data flash programming?

Yes, the R5F10EGDGFB#V0 includes 4 KB of background-operable data flash memory. This allows the CPU to execute code from main flash while simultaneously erasing or programming data flash sectors - eliminating interrupt latency penalties during firmware updates or parameter storage. The R5F10EGDGFB#V0 guarantees 1 million erase cycles and supports 1.8 V to 3.6 V programming voltage, enabling robust nonvolatile data logging in battery-powered devices.

What analog capabilities does the R5F10EGDGFB#V0 provide?

The R5F10EGDGFB#V0 integrates a 12-bit successive-approximation ADC with 28 input channels, 3.375 µs conversion time, and support for analog inputs as low as 1.6 V. It includes internal voltage reference (1.45 V), AVREFP/AVREFM differential reference inputs, and an on-chip temperature sensor. These features enable high-accuracy sensor interfacing in applications like energy metering and environmental monitoring - all without external precision references. The R5F10EGDGFB#V0 also supports ADC self-test for functional safety compliance.

How is pin functionality configured on the R5F10EGDGFB#V0?

Pin functionality on the R5F10EGDGFB#V0 is dynamically assigned using the Peripheral I/O Redirection Register (PIOR). This allows UART, I²C, SPI, timer, and other peripheral signals to be routed to alternate pins - decoupling hardware layout from fixed peripheral mapping. For example, UART0 can be reassigned from default P11/P12 to other GPIOs, enabling optimal PCB routing. The R5F10EGDGFB#V0's 48-pin LFQFP package provides 42 usable I/Os, including 11 N-ch open-drain pins tolerant to 6 V.

What safety features does the R5F10EGDGFB#V0 include for certified applications?

The R5F10EGDGFB#V0 includes multiple hardware safety mechanisms aligned with IEC/UL 60730 requirements: flash memory CRC calculation engine, RAM parity error detection, SFR write protection, illegal memory access detection, clock stop/frequency monitoring, and ADC self-test. These features enable systematic fault detection and recovery - essential for household appliance controllers and industrial safety subsystems. The R5F10EGDGFB#V0 also supports watchdog timer windowing and low-voltage detection with 12 programmable thresholds to prevent erratic behavior during brownout conditions.
