Product details
Overview
R5F110MFAFB#30 from Renesas is an RL78/L1C 80-pin ultra-low-power 16-bit MCU with integrated LCD controller/driver (44 segment × 4 common), 96 KB flash, 8 KB data flash, 8 KB RAM, USB 2.0 function controller, and 12-bit A/D converter-designed for battery-powered LCD-based medical monitors, portable meters, and home appliance control panels.
For engineers reviewing the R5F110MFAFB#30 datasheet, R5F110MFAFB#30 pinout, R5F110MFAFB#30 application, or R5F110MFAFB#30 equivalent, key selection criteria include USB 2.0 full-speed support, 1.6–3.6 V single-supply operation, RTC2 + LVD standby current of 0.68 μA, and 80-pin LFQFP package compatibility with space-constrained industrial HMI designs.
Technical Context
The R5F110MFAFB#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), on-chip high-accuracy ±1.0% oscillator (1–48 MHz), and dual-clock domain (main + subsystem) for independent low-power peripheral operation.
Its LCD controller supports internal voltage boosting, capacitor-split, and external resistor-divider biasing methods; segment output capability is 44 (40) to 56 (52) depending on common count, with COM0–COM7 and SEG0–SEG55 mapped across dedicated port pins. The USB function controller complies with Battery Charging Specification Rev. 1.2 and operates in HS mode only.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F110MGAFB#30 | 128 KB flash, 12 KB RAM, same 80-pin LFQFP package and USB/LCD peripherals | Supports larger firmware images and more complex UI logic; identical pinout and power profile | Select when firmware size exceeds 96 KB or additional RAM buffers are required for USB bulk transfers |
| R5F111MFAFB#30 | No USB controller; otherwise identical flash/RAM/LCD specs and 80-pin LFQFP package | Used where USB is unnecessary-reduces EMI sensitivity and eliminates USB decoupling requirements | Choose for cost-sensitive, non-connectivity applications where USB functionality is omitted |
Compared with R5F110MGAFB#30, the R5F110MFAFB#30 trades flash capacity for lower cost and smaller footprint in USB-enabled designs; versus R5F111MFAFB#30, it adds USB 2.0 at the cost of two dedicated pins (UREGC/UVBUS) and slightly higher standby current due to USB regulator circuitry.

FAQ
What is the maximum LCD segment count supported by the R5F110MFAFB#30?
The R5F110MFAFB#30 supports up to 56 segments with 8 commons or 44 segments with 4 commons, configurable via internal LCD bias circuit selection (capacitor-split, internal boost, or external resistor division). Segment mapping uses dedicated pins including P00–P07, P10–P12, P20–P27, P30–P37, P50–P57, P70–P77, and P140–P143-all confirmed in the R01DS0192EJ0240 datasheet Section 1.3.1 and Figure 1-1.
Does the R5F110MFAFB#30 support USB device enumeration without external crystal?
Yes-the R5F110MFAFB#30 uses its high-accuracy ±1.0% on-chip oscillator (48 MHz option) for USB full-speed operation, eliminating the need for an external USB crystal. However, the UREGC pin must be decoupled with a 0.33 μF capacitor to VSS, and UVBUS must be monitored for VBUS detection per Section 1.3.1 and USB functional description in R01DS0192EJ0240.
What is the guaranteed minimum operating temperature range for the R5F110MFAFB#30?
The R5F110MFAFB#30 is rated for TA = −40 to +85°C (Consumer grade, denoted by "A" in part number suffix), as specified in Section 1.1 and ordering information Table 1.2 of R01DS0192EJ0240. It does not support the extended −40 to +105°C industrial grade (G-suffix) variant.
Can the R5F110MFAFB#30 perform ADC conversions during STOP mode?
No-the 12-bit A/D converter requires the main clock domain and is disabled in STOP mode. However, the R5F110MFAFB#30 supports SNOOZE mode, where selected peripherals (including ADC triggered by LVD or RTC) operate autonomously while CPU remains halted, achieving sub-μA average current in periodic sensing applications.
How many independent PWM outputs does the R5F110MFAFB#30 provide?
The R5F110MFAFB#30 provides 11 channels of 16-bit timer output (TO00–TO07, TO10–TO12), all configurable as edge-aligned or center-aligned PWM with dead-time insertion. These are documented in Section 1.1 "Timers" and block diagram Figure 1.5.1 of R01DS0192EJ0240, with no shared resource conflicts between channels.
