FAQ
What is the maximum operating frequency and power efficiency of the R5F10RLCGFB#10?
The R5F10RLCGFB#10 operates at up to 24 MHz using its high-speed on-chip oscillator (±1% accuracy over voltage and temperature), delivering 31 DMIPS. Its active power consumption is 62.5 µA/MHz, and it achieves 0.64 µA in Halt mode with RTC and LVD enabled - making it ideal for battery-powered LCD applications where runtime and wake-up latency are critical. The R5F10RLCGFB#10 maintains this efficiency across its full 1.6 V to 5.5 V supply range.
Does the R5F10RLCGFB#10 support I²C communication, and what are its electrical characteristics?
Yes, the R5F10RLCGFB#10 integrates a hardware I²C interface (IICA0) on pins P60 (SCLA0) and P61 (SDAA0). Both pins are open-drain and 5 V tolerant, supporting standard-mode (100 kHz) and fast-mode (400 kHz) operation. The peripheral includes dedicated start/stop detection, arbitration, and clock synchronization logic - enabling reliable communication with sensors, EEPROMs, and display controllers without software bit-banging overhead. The R5F10RLCGFB#10's I²C module is fully compatible with SMBus protocols.
How many LCD segments and commons does the R5F10RLCGFB#10 support, and what drive methods are available?
The R5F10RLCGFB#10 supports up to 39 segment outputs and 8 common outputs, configurable as 39 seg × 4 com or 35 seg × 8 com layouts. It offers three LCD drive methods: capacitor split (0.12 µA typical), internal voltage boost (0.63 µA at VDD = 3.0 V), and external resistance division. Segment waveforms A and B are selectable, and contrast is adjustable in 16 steps - giving designers flexibility to match diverse LCD glass specifications. This capability is intrinsic to the R5F10RLCGFB#10's integrated LCD controller.
What safety certifications or built-in features does the R5F10RLCGFB#10 provide for appliance-class applications?
The R5F10RLCGFB#10 includes hardware-level features aligned with IEC 60730 Class B requirements: flash memory CRC calculation engine, RAM parity error detection, SFR write protection, illegal memory access detection, clock frequency monitor, and ADC self-test. These features enable certified firmware implementations for household appliances, HVAC controls, and industrial safety monitors - reducing certification effort and eliminating need for external watchdog ICs. All safety mechanisms are active by default in the R5F10RLCGFB#10's reset state.
Can the R5F10RLCGFB#10 operate from a single 3.0 V coin cell battery, and what peripherals remain functional at low voltage?
Yes, the R5F10RLCGFB#10 operates down to 1.6 V, making it fully compatible with 3.0 V coin cells (e.g., CR2032) across full temperature range (−40°C to +105°C). At 1.6 V, the 10-bit ADC remains functional with internal 1.45 V reference, RTC continues accurate timekeeping, and LCD controller supports capacitor-split drive mode. The R5F10RLCGFB#10's low-voltage detection (LVD) offers 14 programmable thresholds to trigger graceful shutdown or warning before brownout - ensuring robust operation throughout battery discharge.
