Renesas R5F110PGAFB#30

Overview

R5F110PGAFB#30 from Renesas is a 100-pin LFQFP microcontroller in the RL78/L1C family, integrating LCD controller/driver (56-segment/8-common), USB 2.0 function controller, 12-bit A/D converter (12-channel, VDD ≥ 2.4 V), 128 KB flash, and 10 KB RAM. It operates from 1.6–3.6 V with ultra-low power consumption (112.5 μA/MHz active, 0.68 μA RTC2+LVD), targeting battery-powered LCD-based medical devices, industrial HMIs, and smart meters.

For engineers reviewing the R5F110PGAFB#30 datasheet, R5F110PGAFB#30 pinout, R5F110PGAFB#30 application, or R5F110PGAFB#30 equivalent, key selection criteria include USB 2.0 full-speed support, integrated LCD drive capability up to 56 segments, 12-bit ADC accuracy at 2.4–3.6 V, low-power STOP/HALT/SNOOZE modes, and industrial-grade temperature range (−40°C to +105°C).

Technical Context

The R5F110PGAFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and selectable instruction timing (0.04167 μs min @ 24 MHz PLL or 30.5 μs @ 32.768 kHz). It embeds a dedicated USB voltage regulator (UREGC/UVBUS pins), hardware LCD controller supporting internal boost/capacitor-split/external-resistor division, and dual comparator channels with programmable reference selection.

Its peripheral set includes 11× 16-bit timers, real-time clock 2 (RTC2) with calendar and alarm, event link controller (ELC) for autonomous peripheral triggering, data transfer controller (DTC) with chain transfer, and five I²C-compatible interfaces - all operating under a unified low-power platform with POR, LVD (12-level), and on-chip debug support.

FAQ

What is the maximum LCD segment count supported by the R5F110PGAFB#30?

The R5F110PGAFB#30 supports up to 56 segment outputs (SEG0–SEG55) and 8 common outputs (COM0–COM7), enabling direct drive of 44×4 to 56×8 multiplexed LCDs. This matches standard character displays (e.g., 4×20) and small graphic modules without external bias circuitry. Configuration is done via LCD control registers and VL pin settings.

Does the R5F110PGAFB#30 support USB device enumeration without external components?

Yes - the R5F110PGAFB#30 integrates a full-speed USB 2.0 function controller with internal transceiver and 3.3 V regulator. When UREGC is connected to VSS with a 0.33 μF capacitor and UVBUS is supplied with 4.4–5.25 V, the R5F110PGAFB#30 enumerates as a USB device using only passive termination resistors on UDP/UDM. No external PHY or level shifter is required.

What are the valid operating voltage and temperature ranges for the R5F110PGAFB#30?

The R5F110PGAFB#30 operates from 1.6 V to 3.6 V over an industrial temperature range of −40°C to +105°C (G-grade). Its ultra-low-power design achieves 112.5 μA/MHz active current and 0.68 μA RTC2+LVD retention current within this range, making it suitable for battery-powered and thermally demanding applications.

Can the R5F110PGAFB#30 perform ADC conversions while in STOP mode?

No - the 12-bit A/D converter requires the high-speed on-chip oscillator or PLL clock, which is disabled in STOP mode. However, the R5F110PGAFB#30 supports SNOOZE mode, where the ADC can operate autonomously triggered by events (e.g., timer or external interrupt) while the CPU remains halted, achieving sub-10 μA average current during periodic sensing.

How many I²C-compatible interfaces does the R5F110PGAFB#30 provide?

The R5F110PGAFB#30 provides five I²C-compatible interfaces: IICA0 (P60/P61), IIC00 (P00/P01), IIC10 (P10/P11), IIC20 (P10/P11 remapped), and IIC30 (P33/P34). All support standard-mode (100 kbps) and fast-mode (400 kbps) operation, with independent clock control and interrupt vectors - enabling concurrent communication with multiple sensors or displays.
