Product details
Overview
R5F111PFAFB#30 from Renesas is a 100-pin LFQFP 8-bit RL78/L1C microcontroller without USB, featuring 96 KB flash, 12 KB RAM, integrated LCD controller/driver (56-segment/8-common), 12-bit A/D converter (13-channel, VDD=2.4–3.6 V), and ultra-low power operation (0.68 μA in RTC2+LVD mode). It targets battery-powered LCD display systems such as smart meters and portable medical devices.
For engineers reviewing the R5F111PFAFB#30 datasheet, R5F111PFAFB#30 pinout, R5F111PFAFB#30 application, or R5F111PFAFB#30 equivalent, key selection criteria include LCD segment drive capability, low-power real-time clock support, analog input count and resolution, flash endurance for firmware updates, and industrial temperature range (−40 to +105°C).
Technical Context
The RL78 CPU core uses a CISC architecture with 3-stage pipeline and supports instruction execution times from 0.04167 μs (24 MHz) to 30.5 μs (32.768 kHz), enabling dynamic performance/power scaling. It integrates a dedicated LCD controller supporting internal voltage boosting, capacitor split, and external resistor division methods for flexible display bias generation.
Peripheral integration includes 11× 16-bit timers, 1× 12-bit interval timer, 1× RTC2 with calendar and alarm, 2× comparators, 5× serial interfaces (UART/I²C/CSI), and a Data Transfer Controller (DTC) with chain transfer for efficient memory-to-peripheral data movement without CPU intervention.

FAQ
What is the maximum LCD segment count supported by R5F111PFAFB#30?
R5F111PFAFB#30 supports up to 56 segment outputs and 8 common outputs, enabling static or multiplexed driving of monochrome LCDs with up to 448 segments (56 × 8). The controller supports internal voltage boosting, capacitor split, and external resistor division methods-allowing direct compatibility with common STN/FSTN glass types without external bias circuitry.
Does R5F111PFAFB#30 include USB functionality?
No, R5F111PFAFB#30 is part of the "without USB" variant family (indicated by '111' in the part number). It omits USB 2.0 function controller, UREGC, UVBUS, UDP, and UDM pins. For USB-enabled designs, consider the RL78/L1C '110' series (e.g., R5F110PFAFB#30), which shares the same 100-pin LFQFP package but adds full-speed USB 2.0 support.
What analog input channels and resolution does R5F111PFAFB#30 provide?
R5F111PFAFB#30 features a 12-bit A/D converter with 13 analog input channels (ANI0–ANI6, ANI16–ANI21). Resolution is 12-bit only when VDD ≥ 2.4 V; at lower VDD (1.6–2.3 V), it operates at 8/10-bit. Internal reference voltage (1.45 V TYP) and integrated temperature sensor are included for calibration and environmental compensation.
What power-saving modes are available on R5F111PFAFB#30?
R5F111PFAFB#30 offers HALT (112.5 μA/MHz), STOP (0.68 μA with RTC2 + LVD active), and SNOOZE modes. STOP mode retains RAM and register contents while disabling CPU and most peripherals-ideal for long-duration sleep between LCD updates or sensor reads. Wake-up sources include external interrupts, RTC alarms, and comparator events.
Is R5F111PFAFB#30 qualified for industrial temperature operation?
Yes, R5F111PFAFB#30 carries the 'G' suffix (per ordering code R5F111PFAFB#30), indicating qualification for −40 to +105°C ambient operation. This meets industrial-grade requirements for applications such as smart meters, factory HMIs, and outdoor environmental monitors where extended thermal stability is critical.
