Product details
Overview
R5F111PHAFB#10 from Renesas is an RL78/L1C 16-bit microcontroller without USB, featuring 128 KB flash, 12 KB RAM, integrated LCD controller/driver (up to 56 segments × 8 commons), 12-bit A/D converter (13-channel), and ultra-low power operation down to 0.68 μA in RTC2+LVD mode - designed for battery-powered LCD display applications including smart meters and portable medical devices.
For engineers reviewing the R5F111PHAFB#10 datasheet, R5F111PHAFB#10 pinout, R5F111PHAFB#10 application, or R5F111PHAFB#10 equivalent, key selection criteria include segment/common drive capability, 12-bit ADC accuracy at 2.4–3.6 V, real-time clock calendar support, low-power HALT/STOP/SNOOZE modes, and compatibility with Renesas' RL78 toolchain and E2 studio IDE.
Technical Context
The R5F111PHAFB#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.04167 μs min @ 24 MHz to 30.5 μs @ 32.768 kHz). It integrates a dedicated LCD controller supporting internal voltage boosting, capacitor split, or external resistor division methods, with programmable segment outputs (SEG0–SEG55) and common outputs (COM0–COM7).
Peripheral subsystems include 11× 16-bit timers, 1× 12-bit interval timer, RTC2 with 99-year calendar and alarm, 2× comparators, 5× I²C/Simplified I²C channels, 4× UART/LIN, 4× CSI/SPI, 2× D/A converters (8-bit, 0–VDD output), and background data flash rewriting (1M write cycles, 1.8–3.6 V).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F111PJAFB#10 | 256 KB flash, 16 KB RAM, same 100-pin LFQFP package and peripheral set | Supports larger firmware (e.g., OTA update stack + GUI framework) without changing PCB layout | Select when future firmware growth or enhanced data logging requires >128 KB flash |
| R5F111PHGFB#10 | Identical memory and peripherals, but rated for -40°C to +105°C (industrial 'G' grade) | Required for under-hood automotive or factory-floor environments exceeding +85°C ambient | Choose for extended temperature operation; otherwise, R5F111PHAFB#10 suffices for consumer-grade designs |

FAQ
What is the maximum LCD segment count supported by the R5F111PHAFB#10?
The R5F111PHAFB#10 supports up to 56 segment outputs (SEG0–SEG55) and 8 common outputs (COM0–COM7), enabling direct drive of multiplexed LCDs with up to 448 (56 × 8) segments. The actual usable count depends on selected bias method and voltage configuration - confirmed in Section 1.1 and Figure 1-1 of R01DS0192EJ0240.
Does the R5F111PHAFB#10 include USB functionality?
No, the R5F111PHAFB#10 is part of the "products without USB" series (prefix R5F111x). Its ordering code 'R5F111PH' explicitly denotes no USB controller - unlike R5F110x variants. USB-related pins (UREGC, UVBUS, UDM, UDP) are absent, and USB registers are not implemented in this device.
What are the operating voltage and temperature specifications for the R5F111PHAFB#10?
The R5F111PHAFB#10 operates from 1.6 V to 3.6 V over an ambient temperature range of -40°C to +85°C ('A' grade). This is specified in Section 1.1 and confirmed in the "Products without USB" table on Page 3 of R01DS0192EJ0240 - matching its orderable part number suffix 'A'.
How many analog input channels does the R5F111PHAFB#10 support?
The R5F111PHAFB#10 supports 13 analog input channels: ANI0–ANI6, ANI16–ANI21, plus AVREFP and AVREFM used as reference inputs. This is documented in Section 1.1 (A/D converter) and verified in the pin function tables for 100-pin packages on Pages 9–10 of R01DS0192EJ0240.
Is the R5F111PHAFB#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/PLQP0100KP-A). Peripheral function mapping is consistent; only memory size and temperature grade differ between these parts.
