FAQ
What is the maximum LCD segment count supported by the R5F10WMEGFB#30?
The R5F10WMEGFB#30 supports up to 51 segment outputs and 8 common outputs, enabling drive of multiplexed LCDs with up to 408 segments (51 × 8). Configuration options include internal voltage boosting, capacitor-split, or external resistor-divider bias methods-all managed by dedicated LCD control registers in the R5F10WMEGFB#30.
Does the R5F10WMEGFB#30 support background data flash rewriting during program execution?
Yes, the R5F10WMEGFB#30 implements Background Operation (BGO) for its 4 KB data flash memory. This allows the CPU to execute instructions from code flash while simultaneously rewriting data flash-enabling reliable firmware updates, parameter storage, and event logging without system interruption or latency penalties in the R5F10WMEGFB#30.
What are the key differences between the R5F10WMEGFB#30 and R5F10WMEAFB#30?
The R5F10WMEGFB#30 and R5F10WMEAFB#30 share identical flash (48 KB), RAM (2 KB), peripherals, and 80-pin LFQFP package. The sole difference is operating temperature grade: R5F10WMEGFB#30 is rated for −40°C to +105°C (industrial G-suffix), while R5F10WMEAFB#30 is rated for −40°C to +85°C (consumer A-suffix)-a critical distinction for under-hood or factory-floor deployment of the R5F10WMEGFB#30.
How many UART interfaces does the R5F10WMEGFB#30 provide, and which support LIN?
The R5F10WMEGFB#30 provides three UART interfaces. UART2 (accessible on P03/P04) is explicitly LIN-bus compliant per ISO 17987, supporting standard LIN 2.x physical layer signaling including slew-rate control and fault detection. UART0 and UART1 operate as standard asynchronous interfaces without LIN-specific hardware features in the R5F10WMEGFB#30.
Can the R5F10WMEGFB#30 operate from a 1.8 V supply, and what features remain functional?
Yes, the R5F10WMEGFB#30 operates across 1.6 V to 5.5 V. At 1.8 V, all core functions-including 24 MHz high-speed on-chip oscillator (±1.0% accuracy), 10-bit ADC, LCD controller/driver, and real-time clock 2-remain fully operational per datasheet specifications, making the R5F10WMEGFB#30 suitable for single-cell Li-ion or alkaline battery systems.
