Product details
Overview
R5F111PHAFB#30 from Renesas is an RL78/L1C 16-bit microcontroller designed for ultra-low-power LCD-based applications, featuring 128 KB Flash, 12 KB RAM, 12-bit A/D converter (VDD ≥ 2.4 V), integrated LCD controller/driver supporting up to 56 segments and 8 commons, and USB 2.0 function controller (full-speed/low-speed) - deployed in portable medical devices, smart utility meters, and industrial HMI panels.
For engineers reviewing the R5F111PHAFB#30 datasheet, R5F111PHAFB#30 pinout, R5F111PHAFB#30 application, or R5F111PHAFB#30 equivalent, key selection criteria include verified LCD segment drive capability (56 seg / 8 com), USB 2.0 function mode support, true low-power operation (0.68 μA RTC2+LVD), 100-pin LFQFP package compatibility, and absence of USB PHY (requires external UREGC/UVBUS conditioning).
Technical Context
The R5F111PHAFB#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). It integrates a dedicated LCD controller supporting internal voltage boosting, capacitor-split, and external resistor-division bias methods, with programmable VL1–VL4 outputs and CAPH/CAPL terminals.
Its peripheral set includes 11× 16-bit timers, real-time clock 2 (RTC2) with calendar and alarm, 2× comparators, 5× I²C/Simplified I²C channels, 4× UART/LIN, 4× CSI/SPI, 12-bit interval timer, data transfer controller (DTC), and event link controller (ELC) - all operating within 1.6–3.6 V supply and -40°C to +85°C ambient range (Consumer grade "A" variant).

FAQ
What is the maximum LCD segment count supported by the R5F111PHAFB#30?
The R5F111PHAFB#30 supports up to 56 segment outputs (SEG0–SEG55) and 8 common outputs (COM0–COM7), enabling static or multiplexed LCD displays with up to 8-backplane configurations. This is confirmed in the RL78/L1C datasheet Section 1.1 under "LCD controller/driver" and verified in the 100-pin pin configuration diagram (Page 10).
Does the R5F111PHAFB#30 include a USB physical layer (PHY)?
No, the R5F111PHAFB#30 implements only the USB 2.0 function controller logic - it requires external passive components (UREGC capacitor, UVBUS filtering, and ESD protection on UDP/UDM) and does not integrate a full USB PHY. This distinguishes it from the R5F110PHAFB#30, which includes the complete USB transceiver.
What are the operating voltage and temperature specifications for the R5F111PHAFB#30?
The R5F111PHAFB#30 operates from 1.6 V to 3.6 V supply voltage and is rated for -40°C to +85°C ambient temperature (Consumer "A" grade). These values are specified in Section 1.1 "Features" and confirmed in the ordering information table (Page 3) where "A" denotes the consumer temperature range.
How much data flash memory is available on the R5F111PHAFB#30?
The R5F111PHAFB#30 includes 8 KB of data flash memory with background operation (BGO) support, enabling concurrent code execution and data rewriting. It guarantees 1,000,000 write cycles at VDD = 1.8–3.6 V - documented in Section 1.1 "Data flash memory" and Table on Page 2 (Products without USB).
Is the R5F111PHAFB#30 pin-compatible with other RL78/L1C 100-pin variants?
Yes, the R5F111PHAFB#30 shares identical 100-pin LFQFP mechanical dimensions and pinout with all other RL78/L1C 100-pin products (e.g., R5F111PJAFB#30, R5F111PEAFB#30), including matching signal assignments for COM/SEG, USB, power, and reset pins - per Figures 1-1 and 1.3.6 in the datasheet.
