Product details
Overview
R5F111MHAFB#30 from Renesas is an RL78/L1C 80-pin LQFP microcontroller designed for ultra-low-power LCD-based applications. It integrates a 12-bit A/D converter (VDD = 2.4–3.6 V), LCD controller/driver supporting up to 56 segments and 8 commons, and 128 KB flash memory with 8 KB data flash. It operates from 1.6 V to 3.6 V and delivers 33 DMIPS at 24 MHz.
For engineers reviewing the R5F111MHAFB#30 datasheet, R5F111MHAFB#30 pinout, R5F111MHAFB#30 application, or R5F111MHAFB#30 equivalent, key selection criteria include its USB-free architecture, consumer-grade temperature range (−40°C to +85°C), integrated LCD drive capability, low-power STOP/HALT modes (0.68 μA RTC2 + LVD), and support for multiple serial interfaces including UART, CSI, and I²C.
Technical Context
The R5F111MHAFB#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.04167 μs (24 MHz) to 30.5 μs (32.768 kHz). Its peripheral set includes an event link controller (ELC) linking 30+ event sources to peripherals, and a data transfer controller (DTC) supporting block, repeat, and normal transfer modes activated by 30–33 interrupt sources.
It features dual voltage domains (AVDD/AVSS and VDD0/VSS0), on-chip high-speed oscillator (±1.0% accuracy, 1–48 MHz selectable), and dedicated hardware for LCD bias generation via internal boosting, capacitor split, or external resistor division - all configurable per application requirements.

FAQ
What is the maximum LCD segment count supported by the R5F111MHAFB#30?
The R5F111MHAFB#30 supports up to 56 segment outputs (SEG0–SEG55) and 8 common outputs (COM0–COM7), enabling 1:8 multiplexed LCD configurations. This allows driving alphanumeric displays with up to 4 digits plus status icons, or custom segment layouts for instrument panels. The actual usable segments depend on selected bias method and COM count configuration.
Does the R5F111MHAFB#30 include USB functionality?
No, the R5F111MHAFB#30 does not include USB functionality. Per Renesas ordering nomenclature, "111" denotes USB-free variants within the RL78/L1C family. USB-capable equivalents use "110" (e.g., R5F110MHAFB#30). The R5F111MHAFB#30 retains full UART, CSI, and I²C connectivity for alternative communication paths.
What are the key power-saving modes available on the R5F111MHAFB#30?
The R5F111MHAFB#30 offers HALT mode (112.5 μA/MHz), STOP mode (0.68 μA with RTC2 + LVD active), and SNOOZE mode for low-latency wake-up. All modes retain RAM content and select peripheral states. STOP mode is ideal for battery-backed applications requiring calendar and alarm functions without full system wake-up.
Can the R5F111MHAFB#30 operate from a 1.8 V supply?
Yes, the R5F111MHAFB#30 operates across 1.6 V to 3.6 V, making 1.8 V fully supported. At 1.8 V, the maximum operating frequency is reduced per datasheet specifications, and 12-bit ADC operation requires ≥2.4 V-so analog sensing must be deferred to higher VDD or use 8/10-bit mode at 1.8 V.
How many analog input channels does the R5F111MHAFB#30 provide?
The R5F111MHAFB#30 provides 13 analog input channels: ANI0–ANI2, ANI5–ANI6, and ANI16–ANI21. ANI0 and ANI1 double as AVREFP/AVREFM reference inputs. The 12-bit ADC operates at VDD ≥2.4 V; 8/10-bit mode is available down to 1.6 V for broader low-voltage applicability.
