For engineers reviewing the R5F111NJGLA#W0 datasheet, R5F111NJGLA#W0 pinout, R5F111NJGLA#W0 application, or R5F111NJGLA#W0 equivalent, this page delivers verified electrical specs, industrial-grade temperature support (−40°C to +105°C), pin-accurate VFLGA package mapping, and real-world LCD-based use cases with design-meaning context.
Technical Context
The R5F111NJGLA#W0 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 LCD controller supporting internal voltage boosting, capacitor split, and external resistor division methods.
Its peripheral set includes 11 × 16-bit timers, 5-channel I²C/Simplified I²C, 4-channel UART/LIN, 4-channel CSI/SPI, 2 × 8-bit D/A converters, 2 comparators, and Event Link Controller (ELC) for hardware-triggered peripheral chaining - all operating within 1.6–3.6 V supply range.

FAQ
What is the maximum LCD segment count supported by the R5F111NJGLA#W0?
The R5F111NJGLA#W0 supports up to 56 segment outputs (SEG0–SEG55) and 8 common outputs (COM0–COM7), enabling drive of 52-segment LCDs when using 8-com configuration as specified in the RL78/L1C datasheet Section 1.1. This matches its designation as a high-segment-count variant in the L1C family.
Does the R5F111NJGLA#W0 include USB functionality?
No, the R5F111NJGLA#W0 does not include USB functionality. Its part number prefix "111" explicitly denotes the USB-disabled variant of the RL78/L1C family, confirmed in Section 1.2 Ordering Information and Block Diagram 1.5.2. USB-capable equivalents use "110" prefix (e.g., R5F110NJGLA#W0).
What are the key power supply requirements for the R5F111NJGLA#W0?
The R5F111NJGLA#W0 requires separate analog (AVDD/AVSS) and digital (VDD0/VSS0) supplies, both operating from 1.6 V to 3.6 V. The REGC pin must be decoupled to VSS with a 0.47–1 μF capacitor, and industrial-grade operation is validated across −40°C to +105°C at full voltage range.
How many analog input channels does the R5F111NJGLA#W0 support?
The R5F111NJGLA#W0 supports 13 analog input channels: ANI0–ANI6, ANI16–ANI21, plus AVREFP and AVREFM. The 12-bit A/D converter operates at 2.4–3.6 V, with internal 1.45 V reference and temperature sensor - enabling simultaneous acquisition from multiple sensors in portable diagnostics.
What debug and programming interfaces are available on the R5F111NJGLA#W0?
The R5F111NJGLA#W0 includes an on-chip debug system accessible via TOOL0, TOOLRxD, and TOOLTxD pins. It supports self-programming with boot swap and flash shield window functions, and is compatible with Renesas E2 studio and CS+ IDE using standard SWD/JTAG adapters.
