FAQ
What is the maximum LCD segment count supported by R5F111PFGFB#30?
The R5F111PFGFB#30 supports up to 56 segment outputs and 8 common outputs, enabling up to 448-segment LCD displays using 1/8 duty cycle multiplexing. Its configurable LCD bias methods - internal voltage boosting, capacitor split, or external resistance division - allow direct drive of both static and multiplexed segments without external bias ICs. This capability is fully implemented in the R5F111PFGFB#30's hardware and verified in the RL78/L1C datasheet Rev.2.40.
Does R5F111PFGFB#30 include USB functionality?
No, the R5F111PFGFB#30 does not include USB functionality. The "111" in the part number explicitly denotes the USB-disabled variant of the RL78/L1C family, as confirmed in the ordering information table (Page 3) and block diagrams (Pages 13 and 15) of the R01DS0192EJ0240 datasheet. USB-capable variants use "110" (e.g., R5F110PFGFB#30). All other peripherals - LCD, ADC, timers, UART, I²C - remain identical between the 110 and 111 series.
What is the operating temperature range for R5F111PFGFB#30?
The R5F111PFGFB#30 is rated for industrial operation from -40°C to +105°C, as indicated by the "G" suffix in its orderable part number. This specification is validated across all electrical parameters in the datasheet, including flash endurance, ADC accuracy, and LCD driver performance. The device meets this range without derating and is suitable for deployment in uncontrolled industrial enclosures or outdoor metering housings.
How many analog input channels does the 12-bit A/D converter in R5F111PFGFB#30 support?
The R5F111PFGFB#30's 12-bit A/D converter supports 13 analog input channels, comprising ANI0–ANI6, ANI16–ANI21, and AVREFP/AVREFM. This count is explicitly stated in the "A/D converter" feature list (Page 1) and confirmed in the pin function tables (Pages 11–12) of the R01DS0192EJ0240 datasheet. All 13 channels operate at full 12-bit resolution when VDD is 2.4–3.6 V.
What package type and pin count does R5F111PFGFB#30 use?
The R5F111PFGFB#30 uses a 100-pin plastic LFQFP package with 0.5 mm pitch and 14 × 14 mm body size, as designated by "FB" in the part number and confirmed in the ordering information (Page 3) and pin configuration diagram (Page 10) of the RL78/L1C datasheet. This package is RoHS-compliant, industrial-grade, and supplied in trays (#30 packaging specification).
