FAQ
What is the maximum operating frequency and associated current consumption for R5F10WLEGFB#30?
The R5F10WLEGFB#30 supports up to 24 MHz operation using its high-speed on-chip oscillator, achieving 31 DMIPS performance at 71 μA/MHz (1.7 mA typical at 24 MHz). At 1.6 V minimum supply, max frequency drops to 4 MHz in LV mode - verified per Electrical Specifications Table 2.1 in R01DS0168EJ0232.
Does R5F10WLEGFB#30 support hardware-based LCD bias generation without external components?
Yes, R5F10WLEGFB#30 integrates three LCD bias methods: internal voltage boosting (no external capacitors needed), capacitor split (requires 2 external caps), and external resistor division (uses external resistors). The internal boost mode directly generates VL1–VL4 from VDD, enabling single-supply LCD operation.
How many UART interfaces does R5F10WLEGFB#30 include, and which support LIN bus?
R5F10WLEGFB#30 includes three UART channels: UART0, UART1, and UART2. Only UART2 supports LIN bus physical layer compliance (LINSEL pin enables LIN mode), while UART0 and UART1 operate as standard asynchronous serial interfaces - confirmed in Section 1.1 "Features" and Table 1-1 pin function mapping.
Can R5F10WLEGFB#30 perform simultaneous ADC conversion and data flash write operations?
Yes, R5F10WLEGFB#30 supports background operation (BGO) for data flash: instructions execute from code flash while rewriting data flash memory. This allows ADC sampling and result storage to proceed concurrently - specified in "Data flash memory" section with 2-clock transfer latency between SFR and RAM.
What is the exact pin count, package type, and industrial qualification status of R5F10WLEGFB#30?
R5F10WLEGFB#30 is a 64-pin LFQFP (10 × 10 mm, 0.5 mm pitch) device qualified for industrial temperature range (-40°C to +105°C), indicated by the 'G' suffix in the part number and confirmed in Figure 1-1 and Table 1-1 of R01DS0168EJ0232 Rev.2.32.
