Product details
Overview
R5F110MJGFB#30 from Renesas is an ultra-low-power 16-bit RL78/L1C microcontroller with integrated LCD controller/driver (44–56 segment, 4–8 common), 256 KB flash, 16 KB RAM, USB 2.0 function controller (full/low-speed), and 12-bit A/D converter (VDD = 2.4–3.6 V). It operates from 1.6 V to 3.6 V, achieves 33 DMIPS at 24 MHz, and targets battery-powered LCD-based industrial instrumentation.
For engineers reviewing the R5F110MJGFB#30 datasheet, R5F110MJGFB#30 pinout, R5F110MJGFB#30 application, or R5F110MJGFB#30 equivalent, key selection criteria include USB 2.0 function support, 256 KB flash capacity, industrial-grade temperature range (−40°C to +105°C), LFQFP-80 package compatibility, and integrated LCD driving capability for segment-based displays.
Technical Context
The R5F110MJGFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.04167 μs min @ 24 MHz to 30.5 μs @ 32.768 kHz). It integrates a dedicated USB voltage regulator (UREGC/UVBUS pins), supports Battery Charging Specification Rev. 1.2, and uses internal PLL for USB clock generation in HS mode.
Its LCD controller supports three voltage-boosting methods (internal capacitor split, external resistor division, internal voltage boosting) and drives up to 56 segments with 8 commons. The 12-bit A/D converter includes internal reference (1.45 V TYP) and temperature sensor, while the dual-channel 8-bit D/A converter provides real-time analog output (0 V to VDD).

FAQ
What is the maximum LCD segment count supported by the R5F110MJGFB#30?
The R5F110MJGFB#30 supports up to 56 segment outputs and 8 common outputs when configured for 8-common operation. Segment mapping includes SEG0–SEG55, and common outputs are COM0–COM7. This enables driving alphanumeric or custom symbol displays without external segment drivers, directly reducing BOM count and PCB area.
Does the R5F110MJGFB#30 support USB device enumeration without external components?
Yes, the R5F110MJGFB#30 includes a fully integrated USB 2.0 function controller compliant with Battery Charging Specification Rev. 1.2. It requires only passive components: a 0.33 μF capacitor on UREGC, series resistors on UDM/UDP, and proper USB signal routing. No external PHY or transceiver IC is needed for standard full-speed or low-speed device operation.
What are the power supply requirements for the USB interface on the R5F110MJGFB#30?
The R5F110MJGFB#30 USB interface requires UVBUS to be connected to the USB VBUS line (4.4–5.25 V) for detection and power negotiation. The internal USB regulator generates 3.3 V from UVBUS, and UREGC must be decoupled to VSS with a 0.33 μF capacitor. Core logic remains powered by VDD (1.6–3.6 V); USB operation is only enabled in HS (high-speed main) mode.
How many A/D input channels does the R5F110MJGFB#30 provide, and what reference options are available?
The R5F110MJGFB#30 provides 13 analog input channels (ANI0–ANI6, ANI16–ANI21) for its 12-bit A/D converter. Reference options include internal 1.45 V (TYP), AVREFP/AVREFM differential inputs, or external voltage applied to IVREF0/IVREF1 pins. Conversion is valid only when VDD ≥ 2.4 V for 12-bit resolution; 8/10-bit mode operates down to 1.6 V.
Is the R5F110MJGFB#30 pin-compatible with other RL78/L1C variants in the 80-pin LFQFP package?
Yes, all 80-pin RL78/L1C devices - including R5F110MEGFB#30 through R5F110MJGFB#30 and their R5F111x counterparts - share identical pinouts and package dimensions (PLQP0080KB-B). Functional differences (e.g., USB presence, flash size) do not affect mechanical or electrical pin compatibility, enabling drop-in replacement within the same memory/feature tier during design iteration or qualification.
