FAQ
What is the maximum operating frequency and accuracy of the on-chip oscillator in R5F10RBCGFP#10?
The R5F10RBCGFP#10 features a high-speed on-chip oscillator rated at 24 MHz with ±1% accuracy across 1.8 V to 5.5 V supply and −20°C to +85°C temperature range. This eliminates the need for an external crystal in most LCD applications while maintaining timing integrity for UART, timers, and ADC sampling - confirmed in Section 1.1 of R01DS0157EJ0223 Rev.2.23.
Does R5F10RBCGFP#10 support IEC 60730 Class B compliance for appliance control?
Yes, the R5F10RBCGFP#10 includes hardware-level safety features required for IEC 60730 Class B: flash memory CRC calculation, RAM parity error check, SFR write protection, illegal memory access detection, clock frequency monitor, and ADC self-test. These are documented in Section 1.1 "Safety Features" of the datasheet and validated for use in certified white-goods and HVAC control systems.
How many LCD segments and commons does R5F10RBCGFP#10 support, and what drive methods are available?
The R5F10RBCGFP#10 supports up to 35 segment × 4 common or 39 segment × 4 common LCD configurations. It implements three drive methods: capacitor split (0.12 µA), internal voltage boost (0.63 µA @ 3.0 V), and resistance division - all selectable via software registers. Pin assignments for COM0–COM3 and SEG0–SEG32 are defined in Section 1.3.1 of the datasheet.
What is the minimum supply voltage and associated low-power operating current for R5F10RBCGFP#10?
The R5F10RBCGFP#10 operates down to 1.6 V and achieves 0.64 µA in Halt mode with RTC and LVD enabled - verified in Section 1.1 "Ultra-Low Power Technology". In Stop mode (RAM retained), it draws 0.23 µA (LVD disabled) or 0.31 µA (LVD enabled), enabling decade-long battery life in maintenance-free portable instruments.
Can R5F10RBCGFP#10 perform simultaneous ADC conversion and LCD refresh without CPU intervention?
Yes, the R5F10RBCGFP#10 supports background operation of its 10-bit ADC and LCD controller using autonomous peripherals. The DMA controller can transfer ADC results to RAM while the LCD driver refreshes segments - both coordinated by the timer array unit without CPU involvement. This capability is detailed in Sections 1.1 and 1.5.1 of the datasheet.
