FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F10WLEAFB#10?
The R5F10WLEAFB#10 achieves 31 DMIPS at 24 MHz using its high-speed on-chip oscillator. At this frequency, typical active current is 71 µA/MHz (≈1.7 mA total), dropping to 0.61 µA in STOP mode with RTC + LVD enabled. These values are measured at VDD = 3.3 V, TA = 25°C per R01DS0168EJ0232 Rev.2.32.
Does the R5F10WLEAFB#10 support hardware-based LCD bias generation without external components?
Yes, the R5F10WLEAFB#10 integrates an internal voltage boosting circuit for LCD bias, configurable alongside capacitor-split and external resistor-division methods. This eliminates need for external charge-pump ICs when driving 36-segment × 4-common LCDs at standard 3 V supply.
How many UART interfaces does the R5F10WLEAFB#10 include, and which support LIN bus?
The R5F10WLEAFB#10 includes three UART channels: UART0 (P00/P17), UART1 (P06/P07), and UART2 (P03/P04). Only UART0 supports LIN bus protocol via dedicated LINSEL pin functionality, enabling direct connection to automotive body-control networks.
Can the R5F10WLEAFB#10 perform ADC conversions while executing code from flash memory?
Yes-the R5F10WLEAFB#10's 8/10-bit ADC operates independently of CPU execution. Conversions can be triggered by software, timer, or external event, and results are stored in dedicated SFRs without stalling the core, enabling real-time sensor monitoring in active mode.
What debug interface does the R5F10WLEAFB#10 provide, and what pins are required?
The R5F10WLEAFB#10 supports on-chip debugging via the single-wire SWD interface using P40 (TOOL0), P00 (TOOLTxD), and P17 (TOOLRxD) pins. No external debug probe is needed-debugging is enabled through Renesas CS+ or e2 studio IDE with compatible E2 emulator.
