Product details
Overview
R5F111PFAFB#10 from Renesas is a 100-pin LFQFP 8-bit RL78/L1C microcontroller designed for ultra-low-power LCD-based applications. It integrates an LCD controller/driver (56 segment × 4 common), 12-bit A/D converter (12-channel, 2.4–3.6 V range), USB 2.0 function controller (full/low-speed), 96 KB flash, 8 KB data flash, and 10 KB RAM - operating from 1.6 V to 3.6 V across -40°C to +85°C.
For engineers reviewing the R5F111PFAFB#10 datasheet, R5F111PFAFB#10 pinout, R5F111PFAFB#10 application, or R5F111PFAFB#10 equivalent, key selection criteria include LCD segment drive capability, USB 2.0 functional mode support, real-time clock with calendar, low-power STOP/HALT modes, and integrated analog peripherals including dual comparators and D/A converters.
Technical Context
The R5F111PFAFB#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.04167 μs @ 24 MHz to 30.5 μs @ 32.768 kHz). It supports background operation during data flash rewriting and features an Event Link Controller (ELC) linking 30+ event sources to peripheral functions without CPU intervention.
Its power management includes HALT, STOP, and SNOOZE modes achieving as low as 0.68 μA in RTC2 + LVD mode. The USB interface complies with Battery Charging Specification Rev. 1.2 and operates in HS (high-speed main) mode only - no USB PHY is integrated; external UREGC/UVBUS/UDP/UDM connections are required per datasheet cautions.

FAQ
Does R5F111PFAFB#10 include an integrated USB transceiver?
No, the R5F111PFAFB#10 contains only a USB 2.0 function controller - not a physical transceiver. External USB termination (UDP/UDM), VBUS sensing (UVBUS), and regulator capacitance (UREGC) connections are mandatory. The datasheet specifies use of a 0.33 μF capacitor on UREGC and proper PCB layout for signal integrity. This differs from the R5F110PFAFB#10, which integrates the transceiver.
What LCD configurations does R5F111PFAFB#10 support?
The R5F111PFAFB#10 supports up to 56 segment and 8 common outputs, configurable for 4-common operation (56 × 4) or 8-common (40 × 8). It offers three voltage-boost methods: internal charge pump, capacitor-split, or external resistor division - enabling flexible contrast control and compatibility with diverse LCD glass types without external components.
Can R5F111PFAFB#10 operate from a 1.8 V supply?
Yes, the R5F111PFAFB#10 operates across 1.6 V to 3.6 V, including 1.8 V. At 1.8 V, the maximum allowed CPU frequency is 16 MHz (per datasheet voltage-frequency rating), and the 12-bit A/D converter requires ≥2.4 V - so ADC use is disabled below that threshold. The 8/10-bit ADC remains functional at 1.8 V for basic sensing tasks.
How many analog inputs does R5F111PFAFB#10 provide?
The R5F111PFAFB#10 provides 12 dedicated analog input channels: ANI0–ANI6 and ANI16–ANI21. ANI0 and ANI1 double as AVREFP/AVREFM reference inputs. The 12-bit A/D converter operates only at VDD ≥2.4 V; at lower voltages, the 8/10-bit mode is available across the same channel set.
Is R5F111PFAFB#10 pin-compatible with other RL78/L1C 100-pin variants?
Yes, all RL78/L1C 100-pin LFQFP variants - including R5F111MEAFB#10 through R5F111PJAFB#10 - share identical pinouts and package dimensions (PLQP0100KB-B). Differences are limited to flash/RAM size, USB inclusion (R5F110x vs R5F111x), and temperature grade (A vs G), enabling scalable design reuse without PCB revision.
