Product details
Overview
R5F110MHAFB#30 from Renesas is an RL78/L1C 80-pin microcontroller with integrated LCD controller/driver, 12-bit A/D converter, USB 2.0 function controller, and true low-power operation (112.5 μA/MHz active, 0.68 μA in RTC2+LVD mode). It features 128 KB flash, 12 KB RAM, and operates from 1.6–3.6 V for battery-powered LCD-based instrumentation.
For engineers reviewing the R5F110MHAFB#30 datasheet, R5F110MHAFB#30 pinout, R5F110MHAFB#30 application, or R5F110MHAFB#30 equivalent, key selection criteria include USB 2.0 full-speed capability, 44-segment/4-common LCD drive, 12-bit ADC at 2.4–3.6 V, ultra-low power HALT/STOP/SNOOZE modes, and 80-pin LFQFP package compatibility with consumer-grade temperature range (−40 to +85°C).
Technical Context
The R5F110MHAFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction timing (0.04167 μs min @ 24 MHz PLL clock or 30.5 μs @ 32.768 kHz subsystem clock). It integrates a dedicated USB voltage regulator (UREGC/UVBUS), LCD boost circuitry (CAPH/CAPL/TKBOx), and dual-reference comparator (IVCMP0/IVREF0) with VCOUT0 output.
Its peripheral set includes 11× 16-bit timers, real-time clock 2 (RTC2) with calendar and alarm, 5-channel I²C/Simplified I²C, 4-channel UART/LIN, 4-channel CSI (SPI-compatible), and background data flash rewriting (BGO) supporting 1M write cycles at VDD = 1.8–3.6 V.

FAQ
What is the maximum LCD segment count supported by the R5F110MHAFB#30?
The R5F110MHAFB#30 supports up to 44 segment outputs and 4 common outputs, enabling static or 4-multiplex LCD configurations. Pinout confirms SEG0–SEG42 and SEG48–SEG55 as active segment drivers (44 total), with COM0–COM3 assigned as common lines-no hardware support for 5+ commons or >44 segments.
Does the R5F110MHAFB#30 support USB device enumeration without external components?
Yes, the R5F110MHAFB#30 includes a fully integrated USB 2.0 function controller with internal PHY and voltage regulator. When UREGC is decoupled with 0.33 μF to VSS and UDP/UDM are routed with controlled impedance, it enumerates as a USB device (e.g., CDC ACM or HID) without external transceivers or level shifters.
What are the valid operating voltage and temperature ranges for the R5F110MHAFB#30?
The R5F110MHAFB#30 operates from 1.6 V to 3.6 V supply voltage and is rated for −40°C to +85°C ambient temperature (Consumer grade 'A' marking). This range is validated for all specified peripherals including USB, LCD driver, and 12-bit ADC operation-no derating required within these limits.
How many analog input channels does the 12-bit ADC in the R5F110MHAFB#30 support?
The R5F110MHAFB#30's 12-bit A/D converter supports 9 analog input channels (ANI0–ANI2, ANI16–ANI21) when VDD is ≥2.4 V. The 1.45 V internal reference is used by default; external references are not supported for the 12-bit mode-only the 8/10-bit mode accepts AVREFP/AVREFM.
Is the R5F110MHAFB#30 pin-compatible with other RL78/L1C variants in the 80-pin LFQFP package?
Yes, all 80-pin RL78/L1C devices-including R5F110MEAFB#30, R5F110MGAFB#30, and R5F110NJAFB#30-share identical pinout, package dimensions (12×12 mm, 0.5 mm pitch), and electrical characteristics. Peripheral function allocation (e.g., USB pins UREGC/UVBUS/UDP/UDM) is consistent across the family.
