Product details
Overview
R5F111MJGFB#30 from Renesas is an 80-pin LFQFP microcontroller in the RL78/L1C family, designed for ultra-low-power LCD-based applications. It features 256 KB flash, 16 KB RAM, a 12-bit A/D converter (2.4–3.6 V), integrated LCD controller/driver supporting up to 56 segments and 8 commons, and operates from 1.6 V to 3.6 V across -40°C to +105°C industrial temperature range.
For engineers reviewing the R5F111MJGFB#30 datasheet, R5F111MJGFB#30 pinout, R5F111MJGFB#30 application, or R5F111MJGFB#30 equivalent, key selection criteria include LCD segment drive capability, RTC2 with calendar/alarm, USB absence (vs. RL78/L1C USB variants), low-power STOP/HALT modes (0.68 μA RTC2+LVD), and 33 DMIPS @ 24 MHz performance.
Technical Context
The R5F111MJGFB#30 implements the RL78 CPU core-a CISC architecture with 3-stage pipeline-supporting instruction execution times from 0.04167 μs (@24 MHz) to 30.5 μs (@32.768 kHz). It integrates a dedicated LCD controller/driver with internal voltage boosting, capacitor split, and external resistor division methods, configurable for up to 56 segment outputs and 8 common outputs.
It includes dual 8-bit D/A converters, two comparators with selectable reference sources, five I²C channels (including simplified I²C), four UART/LIN interfaces, four CSI/SPI channels, eleven 16-bit timers, and a real-time clock 2 (RTC2) with 99-year calendar, alarm, and clock correction-without USB functionality as confirmed by its "111" series designation and absence of UREGC/UVBUS/UDP/UDM pins in the 80-pin non-USB pinout.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F111MHGFB#30 | 128 KB flash, 12 KB RAM, same 80-pin LFQFP package and peripheral set | Lower memory capacity suits simpler displays or reduced feature sets (e.g., 2-line LCD only) | Select when application firmware size < 128 KB and cost sensitivity outweighs future scalability needs |
| R5F111NJGFB#30 | 85-pin VFLGA (7×7 mm), same 256 KB flash/RAM, adds P82/P83 GPIO and removes COM4–COM7 | Smaller footprint but fewer LCD commons - targets compact designs with ≤4-common displays or added GPIO requirements | Choose for space-constrained layouts where 85-pin VFLGA is acceptable and full 8-common LCD drive is unnecessary |
Compared with R5F111MHGFB#30 and R5F111NJGFB#30, the R5F111MJGFB#30 provides maximum on-chip memory (256 KB) in the standard 80-pin LFQFP package with full 8-common LCD support - making it optimal for feature-rich, production-ready LCD HMI designs requiring long-term code maintainability and display flexibility.

FAQ
What is the maximum LCD segment count supported by R5F111MJGFB#30?
The R5F111MJGFB#30 supports up to 56 segment outputs (SEG0–SEG55) and 8 common outputs (COM0–COM7), enabling multiplexed LCD drive configurations up to 1/8 duty cycle. This allows alphanumeric, symbol, or custom graphical displays commonly used in utility meters and industrial panels. The actual usable segment count depends on selected bias method and commons used.
Does R5F111MJGFB#30 include USB functionality?
No, R5F111MJGFB#30 does not include USB functionality. Its part number prefix "111" explicitly denotes the non-USB variant of the RL78/L1C family. Unlike "110"-series parts (e.g., R5F110MJGFB#30), R5F111MJGFB#30 omits USB transceiver pins (UDM, UDP, UREGC, UVBUS) and related internal circuitry - confirmed by datasheet Section 1.3.2 (80-pin non-USB pinout) and functional overview tables.
What are the key low-power operating modes of R5F111MJGFB#30 and their typical current draw?
R5F111MJGFB#30 offers HALT mode (112.5 μA/MHz), STOP mode (0.68 μA with RTC2 + LVD active), and SNOOZE mode (selective peripheral wake-up). These modes are hardware-optimized for battery longevity: STOP mode sustains calendar time and voltage monitoring while drawing less than 1 μA, making it ideal for decade-long deployments in utility meters and portable instruments.
Can R5F111MJGFB#30 perform simultaneous A/D conversion and LCD refresh?
Yes, R5F111MJGFB#30 supports concurrent operation: its Data Transfer Controller (DTC) enables background A/D conversion result transfers while the CPU executes LCD refresh routines or other tasks. The 12-bit A/D converter can operate independently with programmable trigger sources (e.g., timer overflow), and LCD controller runs autonomously once configured - ensuring deterministic timing for both analog sensing and display updates.
What is the purpose of VL1–VL4 pins on R5F111MJGFB#30?
VL1–VL4 are dedicated LCD bias voltage outputs that supply regulated voltages to the LCD glass. They enable flexible contrast control and drive strength tuning across different LCD types (e.g., STN, FSTN). VL1/VL2 typically provide segment voltage references, while VL3/VL4 supply common-side bias - allowing software-configurable voltage division ratios and optimized power efficiency for each display configuration.
