Product details
Overview
R5F111PJGFB#50 from Renesas is a 100-pin, industrial-grade (−40 to +105°C) RL78/L1C microcontroller without USB, featuring 256 KB flash, 16 KB RAM, integrated LCD controller/driver supporting up to 56 segments and 8 commons, 12-bit A/D converter (2.4–3.6 V), and ultra-low power operation down to 0.68 μA in RTC2+LVD mode - designed for battery-powered LCD-based instrumentation and industrial HMI panels.
For engineers reviewing the R5F111PJGFB#50 datasheet, R5F111PJGFB#50 pinout, R5F111PJGFB#50 application, or R5F111PJGFB#50 equivalent, key selection criteria include segment/common drive capability, 12-bit ADC accuracy at 2.4 V min, industrial temperature support, absence of USB peripheral, and compatibility with Renesas' RL78 toolchain and IAR/CS+ IDEs.
Technical Context
The R5F111PJGFB#50 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, delivering 33 DMIPS at 24 MHz. It integrates a dedicated LCD controller supporting internal voltage boosting, capacitor split, and external resistor division methods - enabling direct drive of multiplexed segment-based displays without external bias circuitry.
Its analog subsystem includes dual 8-bit D/A outputs, two comparators with selectable reference sources, and a 12-bit A/D converter with up to 13 input channels and internal 1.45 V reference. Power management features HALT, STOP, and SNOOZE modes, with real-time clock 2 (RTC2) providing calendar functionality and alarm with ±1 ppm correction.

FAQ
What is the maximum LCD segment count supported by the R5F111PJGFB#50?
The R5F111PJGFB#50 supports up to 56 segment outputs and 8 common outputs, enabling drive of multiplexed LCDs with up to 448 (56 × 8) segment elements. This is confirmed in the RL78/L1C datasheet Section 1.1 under "LCD controller/driver" and matches the 100-pin package's full SEG0–SEG55 and COM0–COM7 pin allocation.
Does the R5F111PJGFB#50 include USB functionality?
No, the R5F111PJGFB#50 does not include USB functionality. Per the Renesas ordering information table (Page 3), part numbers beginning with "R5F111" denote products *without* USB, while "R5F110" denotes USB-enabled variants. The R5F111PJGFB#50 is explicitly classified as a non-USB member of the RL78/L1C family.
What is the operating voltage range for the 12-bit A/D converter in the R5F111PJGFB#50?
The 12-bit A/D converter in the R5F111PJGFB#50 operates only within the 2.4 V to 3.6 V supply range, as specified in the "A/D converter" subsection of Section 1.1. Below 2.4 V, only 8/10-bit resolution is guaranteed; this voltage dependency is a hard silicon limitation, not a configuration option.
Which package type and pin count does the R5F111PJGFB#50 use?
The R5F111PJGFB#50 uses a 100-pin plastic LFQFP package (14 × 14 mm, 0.5 mm pitch), as indicated by the "P" in the orderable part number (denoting 100-pin) and "FB" suffix (denoting LFQFP). This is verified in the "Products without USB" table on Page 3 and the pin configuration diagram on Page 10 of the datasheet.
What industrial temperature grade does the R5F111PJGFB#50 support?
The R5F111PJGFB#50 supports the industrial temperature grade (−40°C to +105°C), denoted by the "G" in its part number. This is explicitly stated in Section 1.2 "Ordering Information" and confirmed in the "Operating ambient temperature" feature list (Page 1), where "G: Industrial applications" maps to TA = −40 to +105°C.
