Product details
Overview
R5F110NEGLA#U0 from Renesas is an ultra-low-power 16-bit RL78/L1C microcontroller with integrated LCD controller/driver (44–56 segment, 4–8 common), 12-bit A/D converter (13-channel, VDD = 2.4–3.6 V), USB 2.0 function controller (full-speed/low-speed), and 96 KB flash memory. It operates from 1.6 V to 3.6 V, achieves 33 DMIPS at 24 MHz, and targets battery-powered LCD-based human-interface devices.
For engineers reviewing the R5F110NEGLA#U0 datasheet, R5F110NEGLA#U0 pinout, R5F110NEGLA#U0 application, or R5F110NEGLA#U0 equivalent, key selection criteria include its VFLGA-85 package, industrial-grade temperature range (−40°C to +105°C), USB 2.0 functionality, LCD drive capability with internal voltage boosting, and true low-power operation down to 0.68 μA in RTC2+LVD mode.
Technical Context
The R5F110NEGLA#U0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction execution time (0.04167 μs @ 24 MHz to 30.5 μs @ 32.768 kHz). It integrates a dedicated USB voltage regulator (UREGC/UVBUS pins), on-chip PLL, and dual-clock system supporting high-speed main and low-speed subsystem clocks.
Its peripheral set includes 11× 16-bit timers, real-time clock 2 (RTC2) with calendar and alarm, 5× I²C-compatible interfaces, 4× UART/LIN channels, 4× CSI/SPI channels, 2× D/A converters (8-bit), and 2× comparators - all coordinated via Event Link Controller (ELC) and Data Transfer Controller (DTC) for autonomous operation.
