Product details
Overview
R5F110NHALA#W0 from Renesas is an ultra-low-power 16-bit RL78/L1C 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 RTC2+LVD). It features 192 KB flash, 12 KB RAM, and operates from 1.6–3.6 V for battery-powered LCD-based instrumentation and portable medical devices.
For engineers reviewing the R5F110NHALA#W0 datasheet, R5F110NHALA#W0 pinout, R5F110NHALA#W0 application, or R5F110NHALA#W0 equivalent, key selection criteria include USB 2.0 full-speed capability, 44–56 segment LCD drive support, 12-bit ADC with internal reference, real-time clock with calendar, and VFLGA-85 package compatibility with space-constrained designs.
Technical Context
The R5F110NHALA#W0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.04167 μs @ 24 MHz to 30.5 μs @ 32.768 kHz). It integrates a dedicated USB 2.0 function controller supporting full-speed (12 Mbps) and low-speed (1.5 Mbps) modes, compliant with Battery Charging Specification Rev. 1.2.
Its LCD controller supports internal voltage boosting, capacitor split, and external resistance division methods, driving up to 56 segments and 8 commons. The 12-bit A/D converter operates at VDD = 2.4–3.6 V with 9–13 analog inputs, internal 1.45 V reference, and temperature sensor - all enabled in the same device variant as specified for R5F110NHALA#W0.

FAQ
What is the maximum LCD segment count supported by R5F110NHALA#W0?
R5F110NHALA#W0 supports up to 56 segment outputs and 8 common outputs, configurable for multiplex ratios up to 1/8 duty. This is confirmed in the RL78/L1C datasheet Section 1.1 under "LCD controller/driver" and verified in the 85-pin package pin listing where SEG0–SEG55 and COM0–COM7 are explicitly assigned. The device achieves this using internal voltage boosting or external resistor division, eliminating need for external LCD drivers.
Does R5F110NHALA#W0 include a hardware USB transceiver?
Yes, R5F110NHALA#W0 integrates a full USB 2.0 function controller with on-die transceiver supporting full-speed (12 Mbps) and low-speed (1.5 Mbps) operation. As stated in Section 1.1 "USB", it complies with Battery Charging Specification Rev. 1.2 and requires only external 0.33 μF URECG decoupling and standard USB termination - no external PHY or transceiver IC is needed for basic USB connectivity.
What are the operating voltage and temperature specifications for R5F110NHALA#W0?
R5F110NHALA#W0 operates from a single 1.6 V to 3.6 V supply and is qualified for consumer applications across -40°C to +85°C ambient temperature. This is defined in Section 1.1 "Features" and confirmed in the Ordering Information table (Page 3), where "A" suffix denotes consumer grade. The part uses #W0 embossed tape packaging compatible with automated SMT assembly.
How much flash and RAM does R5F110NHALA#W0 provide?
R5F110NHALA#W0 provides 192 KB of code flash memory, 8 KB of data flash memory, and 12 KB of on-chip RAM. These values are explicitly listed in the "Products with USB" memory table (Page 2) and cross-referenced in the ordering matrix (Page 3) under R5F110NHALA - "H" denotes 192 KB flash, and "N" indicates 85-pin VFLGA package with consumer temperature grade.
Is R5F110NHALA#W0 pin-compatible with other RL78/L1C variants in the VFLGA-85 package?
Yes, all RL78/L1C 85-pin VFLGA variants - including R5F110NEALA, R5F110NFALA, R5F110NGALA, R5F110NHALA, and R5F110NJALA - share identical pinouts and package dimensions (7 × 7 mm, 0.65 mm pitch). This is confirmed in Section 1.3.3 "85-pin products (with USB)" pin diagrams and reinforced by consistent pin naming (e.g., UREGC, UDP, COM0–COM7, SEG0–SEG55) across all variants in the datasheet.
