FAQ
What is the maximum operating frequency and core performance of the R5F10EBDGNA#W0?
The R5F10EBDGNA#W0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its RL78 16-bit CPU core executes 86% of instructions in just 1–2 clock cycles, enabling deterministic real-time response in control loops and sensor fusion algorithms. The R5F10EBDGNA#W0 maintains this performance across its full 1.6–3.6 V supply range and −40°C to +105°C temperature grade.
Does the R5F10EBDGNA#W0 support hardware-based data flash programming during application runtime?
Yes, the R5F10EBDGNA#W0 supports background data flash programming: its 4 KB data flash can be erased and rewritten while the CPU executes code from main flash memory. This capability enables over-the-air firmware updates, secure key storage, and nonvolatile parameter logging without interrupting real-time operation. The R5F10EBDGNA#W0 guarantees 1 million erase cycles and supports 1.8–3.6 V programming voltage.
How many analog input channels does the R5F10EBDGNA#W0 provide, and what is its ADC resolution and speed?
The R5F10EBDGNA#W0 integrates a 12-bit successive approximation ADC with 18 input channels. It achieves a minimum conversion time of 3.375 µs per sample and supports operation down to 1.6 V supply. An internal 1.45 V reference voltage and dedicated AVREFP/AVREFM pins allow precise ratiometric measurements, making the R5F10EBDGNA#W0 suitable for sensor conditioning and metrology applications.
What low-power modes are available on the R5F10EBDGNA#W0, and what is the lowest current consumption?
The R5F10EBDGNA#W0 offers multiple low-power modes including Stop (0.23 µA RAM-retained), Halt (0.57 µA with RTC + LVD active), and Snooze (0.6–0.7 mA for UART/ADC operation). Its ultra-low 0.57 µA halt mode enables decade-long battery life in always-on monitoring applications. All modes retain RAM content and support wake-up via interrupts, timers, or external events-ensuring rapid resumption of operation. The R5F10EBDGNA#W0 achieves these figures across its full industrial temperature range.
Is the R5F10EBDGNA#W0 pin-compatible with other RL78/G1A variants in the same package?
Yes, all RL78/G1A devices in the 32-pin HWQFN package-including R5F10EBx series members-share identical pinouts and electrical characteristics. This allows direct substitution between R5F10EBDGNA#W0 (48 KB flash), R5F10EBDANA#U0 (same flash, tray packaging), and R5F10EBEGNA#W0 (64 KB flash) without PCB redesign. Firmware updates may be required to leverage additional flash capacity, but hardware layout remains fully reusable across the R5F10EBx family.
