Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F111PGGFB#10 | 256 KB Flash, 16 KB RAM, same package and peripheral set | Required for larger firmware images or extended data logging buffers | Select when application firmware exceeds 128 KB or requires >12 KB RAM for real-time processing |
| R5F110PFGFB#10 | Includes USB PHY and UREVC/UVBUS pins; identical Flash/RAM but adds USB transceiver circuitry | Needed only if full USB device stack implementation with physical layer is required | Choose only if external USB transceiver is not acceptable; otherwise R5F111PFGFB#10 offers lower BOM cost |
Compared with R5F111PGGFB#10, the R5F111PFGFB#10 trades Flash/RAM headroom for cost-sensitive designs; versus R5F110PFGFB#10, it removes redundant USB PHY components to simplify layout and reduce power in USB-hosted systems where host-side enumeration suffices.

FAQ
What is the maximum LCD segment count supported by R5F111PFGFB#10?
The R5F111PFGFB#10 supports up to 56 segment outputs and 8 common outputs, enabling multiplexed driving of alphanumeric or graphical LCDs with up to 448 segment elements (56 × 8). This configuration is confirmed in the RL78/L1C datasheet Section 1.3.6 and Block Diagram 1.5.4 for 100-pin non-USB variants.
Does R5F111PFGFB#10 include a USB physical layer (PHY)?
No, the R5F111PFGFB#10 does not integrate a USB PHY. It contains only the USB function controller logic and requires external USB transceiver circuitry for differential signaling. This is consistent with its "111" prefix indicating no-USB-hardware variants, unlike "110"-prefixed parts which include UREVC/UVBUS/UDP/UDM pins and internal PHY support.
What are the valid operating voltage and temperature ranges for R5F111PFGFB#10?
The R5F111PFGFB#10 operates from 1.6 V to 3.6 V supply voltage and is rated for industrial temperature range of -40°C to +105°C, as indicated by the "G" suffix in the part number and confirmed in Section 1.2 Ordering Information and Section 1.1 Features of the RL78/L1C datasheet.
How many A/D input channels does R5F111PFGFB#10 support, and what resolution is available?
The R5F111PFGFB#10 supports 13 analog input channels with 12-bit resolution when VDD is between 2.4 V and 3.6 V. It also provides 8/10-bit mode at 1.6–3.6 V. The internal 1.45 V reference and integrated temperature sensor are accessible per Section 1.1 Features and Table 1.2 Memory Capacities.
Is R5F111PFGFB#10 pin-compatible with other RL78/L1C 100-pin variants?
Yes, the R5F111PFGFB#10 shares identical 100-pin LFQFP mechanical footprint and pinout with all other RL78/L1C 100-pin packages (e.g., R5F111PEGFB#10, R5F111PHGFB#10), including matching signal assignments for COM/SEG, USB-related pins (unused but bonded), REGC, and all GPIO ports as defined in Section 1.3.6 of the datasheet.
