FAQ

What is the maximum operating frequency and power efficiency of the R5F10RBAGFP#V0?

The R5F10RBAGFP#V0 achieves 31 DMIPS at 24 MHz using its high-speed on-chip oscillator, with operating current of 62.5 µA/MHz. In halt mode with RTC and LVD enabled, it consumes only 0.64 µA - making R5F10RBAGFP#V0 ideal for battery-critical applications like utility meters and portable diagnostics equipment.

Does the R5F10RBAGFP#V0 support external crystal oscillators?

Yes, the R5F10RBAGFP#V0 supports external crystals on pins X1 (P121) and X2 (P122) for main system clock, and XT1/XT2 (P123/P124) for subsystem clock (e.g., 32.768 kHz). It also includes a factory-trimmed 24 MHz on-chip oscillator with ±1% accuracy across voltage and temperature - eliminating the need for external crystal in many cost-sensitive designs.

How many LCD segments and commons does the R5F10RBAGFP#V0 support?

The R5F10RBAGFP#V0 supports up to 35 segments and 4 commons (35 × 4 configuration), with dedicated COM0–COM3 and SEG0/SEG4–SEG6/SEG19–SEG21/SEG27–SEG32 pins. It supports capacitor-split, internal voltage boost, and resistance-division LCD drive methods - all configurable in firmware without external components.

What safety certifications or features does the R5F10RBAGFP#V0 include?

The R5F10RBAGFP#V0 includes hardware-level safety features required for IEC/UL 60730 Class B compliance: flash memory CRC calculation, RAM parity error detection, SFR write protection, illegal memory access detection, clock frequency monitoring, and ADC self-test - enabling certified functional safety in white goods and industrial controls without external supervision circuits.

Can the R5F10RBAGFP#V0 operate from a 1.8 V supply?

Yes, the R5F10RBAGFP#V0 operates across 1.6 V to 5.5 V, including 1.8 V. At 1.8 V, it supports LV (low-voltage) mode up to 4 MHz, full RTC and LVD functionality, and 10-bit ADC operation down to 1.6 V - ensuring reliable startup and operation in energy-harvesting or coin-cell powered systems where supply voltage may dip below 2.0 V.
