Product details
Overview
R5F111PEAFB#30 from Renesas is a 100-pin LFQFP microcontroller in the RL78/L1C family, designed for ultra-low-power LCD-based applications. It integrates an LCD controller/driver (56 segments × 8 commons), 12-bit A/D converter (13-channel, 2.4–3.6 V range), 8-bit D/A converter (2-channel), USB 2.0 function controller (full/low-speed), and operates from 1.6 V to 3.6 V with 64 KB Flash, 8 KB Data Flash, and 8 KB RAM.
For engineers reviewing the R5F111PEAFB#30 datasheet, R5F111PEAFB#30 pinout, R5F111PEAFB#30 application, or R5F111PEAFB#30 equivalent, key selection criteria include LCD segment drive capability, integrated USB functionality, real-time clock with calendar, low-power STOP/HALT modes, and compatibility with battery-powered instrumentation requiring <0.68 μA RTC+LVD operation.
Technical Context
The R5F111PEAFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction timing (0.04167 μs @ 24 MHz to 30.5 μs @ 32.768 kHz). Its on-chip peripherals include 11× 16-bit timers, event link controller (ELC) for peripheral synchronization, data transfer controller (DTC), and simplified SPI/I²C/UART interfaces (5× I²C, 4× UART, 4× CSI).
It supports three LCD driving methods (capacitor split, internal boost, external resistor division), delivers up to 56 segment outputs and 8 common outputs, and features dual comparators with window mode, programmable clock/buzzer outputs (PCLBUZ0/PCLBUZ1), and hardware CRC calculation for firmware integrity verification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F111PJAFB#30 | 256 KB Flash, 16 KB RAM, same 100-pin LFQFP package and peripheral set | Supports larger firmware images and complex UI logic; higher memory headroom for OTA updates | Select when application requires >64 KB code space or extended data logging buffers |

FAQ
What is the maximum LCD segment count supported by the R5F111PEAFB#30?
The R5F111PEAFB#30 supports up to 56 segment outputs and 8 common outputs, enabling static or multiplexed LCD configurations including 4-digit 7-segment plus icons or custom alphanumeric displays. This capability is fixed per the 100-pin variant and does not require external drivers-R5F111PEAFB#30 integrates all necessary bias generation and timing control.
Does the R5F111PEAFB#30 include USB functionality?
No, the R5F111PEAFB#30 is part of the "without USB" subgroup of the RL78/L1C family. While it retains USB-related register maps and software stack compatibility, it lacks the UREGC, UVBUS, UDP, and UDM pins and internal USB voltage regulator. For native USB, select R5F110PEAFB#30 instead-R5F111PEAFB#30 requires external USB-to-UART bridge if serial communication over USB is needed.
What are the power supply requirements for the R5F111PEAFB#30's analog and digital domains?
The R5F111PEAFB#30 requires separate analog (AVDD/AVSS) and digital (VDD0/VSS0/VDD1/VSS1) supplies. AVDD must be 1.6–3.6 V and decoupled with ≥0.1 μF ceramic near the AVDD pin; digital rails accept the same voltage range but must be independently filtered. The REGC pin requires a 0.47–1 μF capacitor to VSS for core regulator stability-R5F111PEAFB#30 cannot operate without this capacitor.
Can the R5F111PEAFB#30 perform simultaneous A/D conversion and LCD refresh?
Yes, the R5F111PEAFB#30 supports concurrent operation: its Event Link Controller (ELC) can trigger A/D conversion start upon timer overflow while LCD refresh runs autonomously from the segment RAM buffer. Background Data Flash rewriting (BGO) further enables firmware updates without halting either function-R5F111PEAFB#30 maintains deterministic real-time behavior across mixed workloads.
What debug interface does the R5F111PEAFB#30 support?
The R5F111PEAFB#30 supports Renesas' on-chip debug interface via the TOOL0, TOOLRxD, and TOOLTxD pins-compatible with E2 emulator Lite and E2 studio IDE. It does not support SWD or JTAG; debugging requires the dedicated TOOL pin assignment and Renesas-specific debug protocol. No external debug probe is needed beyond the standard 6-pin debug connector-R5F111PEAFB#30 includes full flash programming and breakpoint capability in-system.
