Product details
Overview
R5F110MGAFB#30 from Renesas is an RL78/L1C 80-pin low-power MCU with integrated LCD controller/driver (44 segment/4 common), 12-bit A/D converter (12-channel, 2.4–3.6 V range), USB 2.0 function controller (full-speed/low-speed), 128 KB flash, 10 KB RAM, and true low-power operation (112.5 μA/MHz active, 0.68 μA RTC2+LVD). It targets battery-powered LCD-based medical devices, portable meters, and industrial HMI panels.
For engineers reviewing the R5F110MGAFB#30 datasheet, R5F110MGAFB#30 pinout, R5F110MGAFB#30 application, or R5F110MGAFB#30 equivalent, key selection criteria include USB 2.0 function support, LCD drive capability (44 seg/4 com), 12-bit ADC accuracy at 2.4–3.6 V, 80-pin LFQFP package compatibility, and industrial-grade temperature range (−40 to +105°C).
Technical Context
The R5F110MGAFB#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 USB voltage regulator (UREGC/UVBUS pins), LCD boost circuitry (CAPH/CAPL), and dual-reference ADC (internal 1.45 V ref + external AVREFP/AVREFM).
Its peripheral set includes 11× 16-bit timers, real-time clock 2 (99-year calendar), event link controller (30 signal types), data transfer controller (33 activation sources), and five I²C channels - all configurable via peripheral I/O redirection register (PIOR) for flexible pin assignment in 80-pin LFQFP layout.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F110MGAFB#30?
The R5F110MGAFB#30 operates up to 24 MHz using its high-speed on-chip oscillator or PLL, delivering 33 DMIPS. Its minimum instruction execution time is 0.04167 μs at 24 MHz, and it supports ultra-low-speed operation down to 32.768 kHz (30.5 μs/instruction) for RTC and wake-up functions - enabling dynamic power/performance scaling in the R5F110MGAFB#30.
Does the R5F110MGAFB#30 support 12-bit analog-to-digital conversion across its full supply range?
No - the 12-bit A/D converter in the R5F110MGAFB#30 requires VDD ≥ 2.4 V. At 1.6–2.3 V, only 8/10-bit operation is guaranteed. This design constraint ensures ADC linearity and reference stability; users must verify supply voltage compliance before deploying 12-bit measurement features in the R5F110MGAFB#30.
How many LCD segments and commons does the R5F110MGAFB#30 support in its 80-pin configuration?
In the 80-pin LFQFP package, the R5F110MGAFB#30 supports up to 44 segment outputs and 4 common outputs (SEG0–SEG43, COM0–COM3), as confirmed in the pin configuration diagram and block diagram. This matches the "44 (40)" notation in the datasheet, where parentheses indicate 40 segments when 8 commons are used - not applicable to this 4-common variant of the R5F110MGAFB#30.
What USB power and signal integrity requirements apply to the R5F110MGAFB#30?
The R5F110MGAFB#30 requires a 0.33 μF capacitor between UREGC and VSS, and UVBUS must be connected to the USB VBUS line for power detection. UDM/UDP form a differential pair routed as controlled-impedance traces (90 Ω differential); ESD protection diodes are recommended externally. These requirements ensure reliable USB enumeration and BC 1.2 charging detection in the R5F110MGAFB#30.
Can the R5F110MGAFB#30 operate in industrial temperature conditions without derating?
Yes - the R5F110MGAFB#30 is rated for −40 to +105°C ambient operation (industrial 'G' grade). All specifications - including 12-bit ADC accuracy, USB 2.0 timing, LCD drive strength, and flash write endurance - are guaranteed across this full range per the datasheet's TA = −40 to +105°C condition. No thermal derating is needed for the R5F110MGAFB#30 in conformal-coated industrial enclosures.
