Product details
Overview
R5F111MJAFB#30 from Renesas is an RL78/L1C 80-pin LQFP microcontroller without USB, featuring 256 KB Flash, 16 KB RAM, integrated LCD controller/driver (44 segment/4 common), 12-bit A/D converter (13-channel, VDD=2.4–3.6 V), and ultra-low power operation (0.68 μA in RTC2+LVD mode). It targets battery-powered LCD display systems such as smart meters and portable medical devices.
For engineers reviewing the R5F111MJAFB#30 datasheet, R5F111MJAFB#30 pinout, R5F111MJAFB#30 application, or R5F111MJAFB#30 equivalent, key selection criteria include LCD segment drive capability, low-power real-time clock support, analog input resolution and channel count, Flash/RAM sizing for firmware complexity, and absence of USB interface in this variant.
Technical Context
The R5F111MJAFB#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 LCD controller supporting internal voltage boosting, capacitor split, or external resistor division methods.
Power management includes HALT, STOP, and SNOOZE modes; on-chip POR and 12-level LVD; and dual oscillators (high-speed on-chip oscillator ±1.0% accuracy, low-speed 32.768 kHz crystal). The device supports background data flash rewriting (1M write cycles) and real-time D/A output on two channels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F111MHAFB#30 | 128 KB Flash, 12 KB RAM, same 80-pin LFQFP package and peripheral set | Suitable for less complex firmware with smaller code footprint and reduced RAM needs | Select when application logic fits within 128 KB Flash and does not require full 256 KB headroom |
| R5F110MJAFB#30 | Same Flash/RAM, but includes USB 2.0 function controller (full/low-speed) and UREGC/UVBUS/UDP/UDM pins | Required where host-side USB connectivity (e.g., PC configuration, firmware update) is mandatory | Choose only if USB device functionality is needed; R5F111MJAFB#30 lacks USB PHY and related pins |
Compared with R5F111MHAFB#30, the R5F111MJAFB#30 provides double Flash and 4 KB more RAM for larger firmware and data buffers; versus R5F110MJAFB#30, it removes USB hardware to reduce cost and layout complexity in non-USB systems.

FAQ
What is the maximum LCD segment count supported by the R5F111MJAFB#30?
The R5F111MJAFB#30 supports up to 44 segment outputs (SEG0–SEG6, SEG12–SEG25, SEG27–SEG42, SEG48–SEG55) and 4 common outputs (COM0–COM3) in its integrated LCD controller/driver. This configuration enables driving standard 4-digit, 7-segment plus symbol displays or custom alphanumeric panels without external segment drivers.
Does the R5F111MJAFB#30 include USB functionality?
No, the R5F111MJAFB#30 does not include USB functionality. Its part number prefix "111" explicitly denotes the USB-less variant of the RL78/L1C family. Devices with USB bear prefix "110" (e.g., R5F110MJAFB#30) and feature additional pins UREGC, UVBUS, UDP, and UDM - none of which are present on the R5F111MJAFB#30.
What are the operating voltage and temperature ranges for the R5F111MJAFB#30?
The R5F111MJAFB#30 operates from 1.6 V to 3.6 V over an ambient temperature range of -40°C to +85°C. This "A" grade designation confirms its qualification for consumer applications; industrial-grade variants (suffix "G") extend to +105°C but are not applicable to this specific orderable part number.
How many analog input channels does the R5F111MJAFB#30 support in 12-bit mode?
The R5F111MJAFB#30 supports 13 analog input channels (ANI0–ANI6, ANI16–ANI21) for its 12-bit A/D converter, but only when powered at VDD ≥ 2.4 V. At lower voltages (1.6–2.3 V), the A/D operates in 8/10-bit mode with the same channel count. Internal reference voltage (1.45 V TYP.) and temperature sensor are accessible in all modes.
What packaging and ordering specification applies to R5F111MJAFB#30?
The R5F111MJAFB#30 uses an 80-pin plastic LFQFP package (12 × 12 mm, 0.5 mm pitch) with tray packaging (#30 specification). The "FB" in the part number confirms the LFQFP type, "A" indicates consumer temperature grade (-40°C to +85°C), and "J" specifies 256 KB Flash memory capacity - all consistent with Renesas' RL78/L1C naming convention.
