Product details
Overview
R5F110PHAFB#10 from Renesas is an RL78/L1C 16-bit microcontroller with integrated LCD controller/driver (56 segment × 4 common), 12-bit A/D converter (13-channel, 2.4–3.6 V range), USB 2.0 function controller (full-speed/low-speed), 128 KB flash, 12 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, smart meters, and industrial HMI panels.
For engineers reviewing the R5F110PHAFB#10 datasheet, R5F110PHAFB#10 pinout, R5F110PHAFB#10 application, or R5F110PHAFB#10 equivalent, key selection considerations include USB 2.0 function support, 100-pin LFQFP package with dedicated LCD voltage boosting circuitry, 12-bit ADC accuracy at 2.4–3.6 V, and HALT/STOP/SNOOZE power modes for energy-constrained designs.
Technical Context
The R5F110PHAFB#10 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 integrates a dedicated LCD controller supporting internal voltage boosting, capacitor split, and external resistor division methods - enabling direct drive of up to 56-segment × 4-common displays without external bias circuitry.
Its USB 2.0 function controller supports Battery Charging Specification Rev. 1.2 and operates in full-speed (12 Mbps) or low-speed (1.5 Mbps) mode. The 12-bit A/D converter includes internal reference (1.45 V TYP) and temperature sensor, while the DTC and ELC enable autonomous peripheral coordination without CPU intervention.
