Product details
Overview
R5F111MFGFB#30 from Renesas is an RL78/L1C 80-pin low-power 16-bit MCU with integrated LCD controller/driver (44 segment/4 common), 12-bit A/D converter (12-channel, 2.4–3.6 V range), and 128 KB flash/8 KB data flash/12 KB RAM. It operates from 1.6–3.6 V, achieves 33 DMIPS at 24 MHz, and targets battery-powered LCD display applications such as smart meters and portable medical devices.
For engineers reviewing the R5F111MFGFB#30 datasheet, R5F111MFGFB#30 pinout, R5F111MFGFB#30 application, or R5F111MFGFB#30 equivalent, key selection criteria include its USB-free architecture, industrial-grade temperature range (−40 to +105°C), ultra-low power STOP mode (0.68 μA), and dedicated LCD voltage boosting circuitry for direct segment drive without external components.
Technical Context
The R5F111MFGFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction timing (0.04167 μs min @ 24 MHz to 30.5 μs @ 32.768 kHz). It integrates a 12-bit interval timer, RTC2 with calendar/alarm/correction, and dual DTC/ELC peripherals for autonomous peripheral coordination without CPU intervention.
Its LCD controller supports internal voltage boosting, capacitor-split, and external resistor-division methods; segment outputs cover SEG0–SEG55 (44 active in 80-pin variant), with COM0–COM7 and VL1–VL4 power rails. The A/D converter includes internal 1.45 V reference and on-chip temperature sensor, while two 8-bit D/A channels support real-time analog output.

FAQ
What is the maximum LCD segment count supported by the R5F111MFGFB#30?
The R5F111MFGFB#30 supports up to 44 segment outputs and 4 common outputs in its 80-pin LFQFP configuration, as confirmed in the RL78/L1C datasheet Section 1.1 Features and Figure 1-1. This matches the physical pin allocation for SEG0–SEG55 (44 active) and COM0–COM7 (4 used), enabling direct drive of standard 4-digit, 7-segment plus decimal point displays without external drivers. The R5F111MFGFB#30 does not support 8-common configurations in this package.
Does the R5F111MFGFB#30 include USB functionality?
No, the R5F111MFGFB#30 does not include USB functionality. Per the RL78/L1C ordering information (Section 1.2), part numbers beginning with "R5F111" denote products *without* USB, whereas "R5F110" denotes USB-enabled variants. The R5F111MFGFB#30 belongs to the USB-free family and omits UREGC, UBUS, UDP, and UDM pins entirely-confirmed by comparing Figures 1.3.1 (with USB) and 1.3.2 (without USB) in the datasheet.
What is the operating temperature range for the R5F111MFGFB#30?
The R5F111MFGFB#30 is rated for industrial operation from −40 to +105°C, indicated by the "G" suffix in its orderable part number per Section 1.2 of the datasheet. This distinguishes it from consumer-grade "A" variants (−40 to +85°C). The extended range is validated across all core peripherals including the LCD controller, A/D converter, and real-time clock, making the R5F111MFGFB#30 suitable for deployment in uncontrolled ambient environments such as outdoor utility meters or factory-floor HMIs.
How much data flash memory does the R5F111MFGFB#30 provide, and what is its endurance?
The R5F111MFGFB#30 includes 8 KB of data flash memory with a rated endurance of 1,000,000 write cycles (typical), as specified in Section 1.1 Features of the RL78/L1C datasheet. This memory supports background operation (BGO), allowing CPU code execution from program flash while data flash is being rewritten-critical for logging sensor data or storing calibration parameters without system interruption. Voltage requirements for rewriting are 1.8–3.6 V.
Which oscillator options are available for the R5F111MFGFB#30, and what accuracy is guaranteed?
The R5F111MFGFB#30 features a high-speed on-chip oscillator selectable from 48/24/16/12/8/6/4/3/2/1 MHz with ±1.0% accuracy over VDD = 1.8–3.6 V and TA = −20 to +85°C. It also includes a low-speed on-chip oscillator for watchdog and STOP mode operation, plus support for external crystals (X1/X2, XT1/XT2) up to 20 MHz. No PLL is present in the R5F111MFGFB#30-unlike USB-equipped R5F110 variants-so frequency multiplication is not supported.
