Product details
Overview
R5F110MEGFB#30 from Renesas is an RL78/L1C 80-pin, industrial-grade (−40 to +105°C) 16-bit MCU with integrated LCD controller/driver (44 segment × 4 common), 12-bit A/D converter (13-channel, VDD = 2.4–3.6 V), USB 2.0 function controller (full-speed/low-speed), and true low-power operation (112.5 μA/MHz active, 0.68 μA RTC2+LVD). It targets battery-powered LCD-based medical devices, industrial HMIs, and portable instrumentation.
For engineers reviewing the R5F110MEGFB#30 datasheet, R5F110MEGFB#30 pinout, R5F110MEGFB#30 application, or R5F110MEGFB#30 equivalent, key selection criteria include USB functionality, LCD drive capability (segment/common count), 12-bit ADC resolution at 2.4–3.6 V, industrial temperature range, and LFQFP-80 package compatibility with existing 12×12 mm layouts.
Technical Context
The R5F110MEGFB#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 USB voltage regulator (UREGC/UVBUS pins), on-chip PLL for USB clock generation, and dual-voltage domain LCD driver supporting internal boosting, capacitor split, or external resistor division.
Its peripheral set includes 11× 16-bit timers, real-time clock 2 (99-year calendar, alarm, correction), 5× I²C/Simplified I²C channels, 4× UART/LIN, 4× CSI/SPI, 2× 8-bit D/A converters, and 2× comparators - all coordinated via Event Link Controller (ELC) and Data Transfer Controller (DTC) for autonomous low-CPU-load operation.

FAQ
What is the maximum LCD segment count supported by the R5F110MEGFB#30?
The R5F110MEGFB#30 supports up to 44 segment outputs and 4 common outputs, enabling static or 1/4-duty multiplexed LCD displays. When configured for 8-common operation (via register setting), segment count reduces to 40 - confirmed in Section 1.1 "LCD controller/driver" of the R01DS0192EJ0240 datasheet. This matches the physical pinout (SEG0–SEG43) and functional specification for 80-pin USB-enabled variants.
Does the R5F110MEGFB#30 support USB device charging detection per BC 1.2?
Yes, the R5F110MEGFB#30 explicitly supports Battery Charging Specification Revision 1.2, as stated in Section 1.1 "USB" of the R01DS0192EJ0240 datasheet. Its USB function controller detects Dedicated Charging Ports (DCP), Charging Downstream Ports (CDP), and Standard Downstream Ports (SDP) using the UVBUS pin and internal enumeration logic - enabling compliant wall adapter identification without external circuitry.
What are the voltage requirements for achieving 12-bit ADC accuracy on the R5F110MEGFB#30?
The R5F110MEGFB#30 delivers 12-bit A/D conversion only when VDD is maintained between 2.4 V and 3.6 V, as specified in Section 1.1 "A/D converter". At VDD < 2.4 V, the ADC reverts to 8/10-bit mode. The internal reference voltage is TYP. 1.45 V, and analog inputs must remain within AVSS to AVDD; using AVREFP/AVREFM pins enables ratiometric measurement against external references.
How does the R5F110MEGFB#30 achieve 0.68 μA STOP mode current?
The R5F110MEGFB#30 achieves 0.68 μA in STOP mode by powering down the CPU, flash, most peripherals, and main regulator while retaining operation of RTC2, LVD, and associated wakeup logic - all supplied from a dedicated low-leakage domain. This value is measured at VDD = 3.0 V, TA = 25°C, with RTC2 and LVD enabled, per Section 1.1 "Ultra-low power consumption technology" in the datasheet.
Is the R5F110MEGFB#30 pin-compatible with other RL78/L1C 80-pin variants?
Yes, the R5F110MEGFB#30 shares identical pinout and package (PLQP0080KB-B, 80-pin LFQFP) with all other 80-pin RL78/L1C USB-enabled variants (e.g., R5F110MGGB#30, R5F110MJGFB#30), as verified in Section 1.3.1 "Pin Configuration (Top View)" and Table "Ordering Information" of R01DS0192EJ0240. Signal functions may differ per pin due to peripheral redirection, but mechanical and power/ground pin mapping is fully compatible.
