Product details
Overview
R5F111MHGFB#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. Operating from 1.6 V to 3.6 V, it delivers 33 DMIPS at 24 MHz and achieves as low as 0.68 μA in RTC2 + LVD STOP mode - ideal for battery-powered medical meters and portable instrumentation.
For engineers reviewing the R5F111MHGFB#30 datasheet, R5F111MHGFB#30 pinout, R5F111MHGFB#30 application, or R5F111MHGFB#30 equivalent, key selection criteria include confirmed 80-pin LFQFP (12 × 12 mm, 0.5 mm pitch) package, industrial-grade temperature range (−40°C to +105°C), absence of USB functionality, and verified LCD segment drive capability (SEG0–SEG55, COM0–COM7) with internal voltage boosting support.
Technical Context
The R5F111MHGFB#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 features a dedicated LCD controller with programmable bias generation, dual comparator channels (IVCMP0/IVCMP1), and real-time clock 2 (RTC2) with calendar, alarm, and clock correction functions.
Peripheral integration includes 11-channel 16-bit timer array, 5-channel I²C/Simplified I²C, 4-channel UART/LIN, 4-channel CSI/SPI, 12-bit interval timer, and background operation-capable data flash (1M rewrite cycles, BGO supported). Power management supports HALT, STOP, and SNOOZE modes with on-chip LVD (12 selectable levels) and POR.

FAQ
What is the maximum LCD segment count supported by the R5F111MHGFB#30?
The R5F111MHGFB#30 supports up to 56 segment outputs (SEG0–SEG55) and 8 common outputs (COM0–COM7), enabling multiplexed LCD displays with up to 448 segment elements. This configuration is confirmed in the RL78/L1C datasheet Section 1.1 and block diagram Figure 1.5.4 for 80/100-pin non-USB variants. The actual usable count depends on selected bias method and COM/SEG assignment.
Does the R5F111MHGFB#30 include USB functionality?
No, the R5F111MHGFB#30 does not include USB functionality. Its part number suffix "111" explicitly denotes the USB-disabled variant within the RL78/L1C family, as defined in Section 1.2 Ordering Information and Figure 1-1 of the datasheet. USB-capable equivalents use "110" (e.g., R5F110MHGFB#30) and require UREGC, UBUS, UDP, and UDM pins absent in this device.
What are the key power modes and their typical current consumption for R5F111MHGFB#30?
The R5F111MHGFB#30 supports HALT (112.5 μA/MHz), STOP (0.68 μA with RTC2 + LVD enabled), and SNOOZE modes. STOP mode current is measured at VDD = 3.0 V, TA = 25°C per datasheet Section 1.1. These values assume default oscillator settings and disabled unused peripherals; actual consumption varies with clock source, voltage, and peripheral activation state.
Which analog-to-digital converter resolution is available on the R5F111MHGFB#30?
The R5F111MHGFB#30 supports both 8/10-bit and 12-bit A/D conversion. The 12-bit mode operates only when VDD is ≥ 2.4 V, delivering higher precision for sensor measurements. The 8/10-bit mode is available across the full 1.6–3.6 V operating range. Internal reference voltage (TYP. 1.45 V) and temperature sensor are accessible in all A/D configurations.
Is the R5F111MHGFB#30 pin-compatible with other RL78/L1C 80-pin variants?
Yes, the R5F111MHGFB#30 shares identical 80-pin LFQFP pinout (PLQP0080KB-B) with all other 80-pin RL78/L1C devices, including R5F111MGGB#30 and R5F111MJGB#30. Pin functions are consistent across the family per Section 1.3.2 of the datasheet; differences exist only in memory size and feature enablement (e.g., USB), not physical connectivity.
