Product details
Overview
R5F110MGGFB#70 from Renesas is an RL78/L1C 80-pin low-power MCU with integrated LCD controller/driver (44–56 segment, 4–8 common), 12-bit A/D converter (13-channel, VDD=2.4–3.6 V), USB 2.0 function controller (full-speed/low-speed), 128 KB flash, 8 KB data flash, and 12 KB RAM. It operates from 1.6–3.6 V and targets battery-powered LCD-based industrial instrumentation.
For engineers reviewing the R5F110MGGFB#70 datasheet, R5F110MGGFB#70 pinout, R5F110MGGFB#70 application, or R5F110MGGFB#70 equivalent, key selection criteria include industrial temperature range (−40 to +105°C), USB 2.0 functional capability, on-chip LCD drive support for up to 56 segments, ultra-low power HALT/STOP/SNOOZE modes, and 12-bit ADC performance at 2.4–3.6 V supply.
Technical Context
The R5F110MGGFB#70 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.04167 μs @ 24 MHz to 30.5 μs @ 32.768 kHz). It integrates a dedicated USB voltage regulator (UREGC/UVBUS pins), LCD charge pump circuitry (CAPH/CAPL, VL1–VL4), and dual-reference comparator (IVCMP0/IVREF0, VCOUT0).
Its peripheral set includes 11× 16-bit timers, real-time clock 2 (RTC2) with calendar and alarm, event link controller (ELC) for hardware-triggered peripheral chaining, and data transfer controller (DTC) supporting block/chain transfers activated by 30+ interrupt sources - all optimized for deterministic response in LCD-driven human interface applications.

FAQ
What is the maximum LCD segment count supported by the R5F110MGGFB#70?
The R5F110MGGFB#70 supports up to 56 segment outputs and 8 common outputs when configured for 8-common operation. Segment count scales inversely with common count: 52 segments with 8 COMs, 44 segments with 4 COMs. This is confirmed in Section 1.1 Features and Figure 1-1 of the R01DS0192EJ0240 datasheet.
Does the R5F110MGGFB#70 support 12-bit ADC operation at 1.8 V supply?
No. The R5F110MGGFB#70's 12-bit ADC requires VDD ≥ 2.4 V, as explicitly stated in the "A/D converter" subsection of Section 1.1 Features. At 1.6–2.3 V, only 8/10-bit ADC operation is guaranteed. This voltage dependency is a hard silicon limitation, not a configuration option.
Is USB device functionality available in STOP mode on the R5F110MGGFB#70?
No. USB operation requires the high-speed on-chip oscillator or PLL clock, which is disabled in STOP mode. The R5F110MGGFB#70 can only maintain USB connectivity in HALT or ACTIVE modes. STOP mode retains RTC2 and LVD but powers down all clocks except the subsystem oscillator (32.768 kHz).
What packaging and reel specifications apply to the R5F110MGGFB#70?
The R5F110MGGFB#70 uses an 80-pin LFQFP package (12 × 12 mm, 0.5 mm pitch) and ships in trays (#70 specification per Section 1.2 Ordering Information). It is not supplied in tape-and-reel format - #50 denotes embossed tape for other variants, but #70 confirms tray packaging for this industrial-grade part.
How does the R5F110MGGFB#70 handle LCD contrast adjustment?
The R5F110MGGFB#70 adjusts LCD contrast via programmable VL1–VL4 outputs, which generate bias voltages using internal resistor dividers or external capacitive charge pumps (CAPH/CAPL). Contrast level is controlled by register settings selecting voltage division ratio and boost stage activation - no external DAC or potentiometer required.
