Renesas R5F110PEAFB#30

Overview

R5F110PEAFB#30 from Renesas is a 100-pin RL78/L1C 16-bit microcontroller with integrated LCD controller/driver (56-segment, 8-common), USB 2.0 function controller (full-speed/low-speed), 12-bit A/D converter (13-channel, VDD=2.4–3.6 V), 256 KB flash, 16 KB RAM, and true low-power operation (112.5 μA/MHz active, 0.68 μA RTC2+LVD). It targets battery-powered LCD-based medical monitors, portable instrumentation, and industrial HMI panels.

For engineers reviewing the R5F110PEAFB#30 datasheet, R5F110PEAFB#30 pinout, R5F110PEAFB#30 application, or R5F110PEAFB#30 equivalent, key selection criteria include USB 2.0 function support, 100-pin LFQFP package with LCD segment/common drive capability, 12-bit ADC accuracy at 2.4–3.6 V, real-time clock calendar functionality, and ultra-low power HALT/STOP/SNOOZE modes for extended battery life.

Technical Context

The R5F110PEAFB#30 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 for USB clock generation, and dual-voltage domain operation (1.6–3.6 V core/analog supply).

Its LCD controller supports internal voltage boosting, capacitor split, and external resistor division methods; segment outputs (SEG0–SEG55) and common outputs (COM0–COM7) are fully configurable via register settings. The USB interface complies with Battery Charging Specification Rev. 1.2 and operates in full-speed (12 Mbps) or low-speed (1.5 Mbps) mode.

FAQ

What USB speed modes does the R5F110PEAFB#30 support?

The R5F110PEAFB#30 supports both full-speed (12 Mbps) and low-speed (1.5 Mbps) USB 2.0 operation. Its integrated USB function controller requires no external PHY-only UREGC (0.33 μF to VSS), UVBUS, UDP, and UDM connections. Full-speed mode is used for bulk data transfer (e.g., firmware updates), while low-speed mode suits simple control channel applications.

How many LCD segments and commons does the R5F110PEAFB#30 drive?

The R5F110PEAFB#30 drives up to 56 segment outputs (SEG0–SEG55) and 8 common outputs (COM0–COM7), enabling up to 448 distinct LCD segments in multiplexed configurations. This capacity supports alphanumeric displays with icons, commonly used in portable medical and industrial instruments. Segment and common assignments are fully configurable via LCD control registers.

Does the R5F110PEAFB#30 include a temperature sensor?

Yes, the R5F110PEAFB#30 includes an on-chip temperature sensor accessible via the 12-bit A/D converter. When enabled, it provides calibrated readings referenced to the internal 1.45 V bandgap voltage. This sensor is usable across the full operating range (–40°C to +85°C for 'A' grade) and supports automatic compensation in battery-powered systems.

What is the minimum operating voltage for the R5F110PEAFB#30?

The R5F110PEAFB#30 operates from a single supply of 1.6 V to 3.6 V. At 1.6 V, core functionality (CPU, flash, RAM, timers, GPIO) remains active, though USB and high-speed peripherals require ≥2.7 V. This wide range enables direct use with single-cell lithium batteries (2.5–3.6 V) and extends runtime down to end-of-discharge voltage.

Is the R5F110PEAFB#30 pin-compatible with other RL78/L1C variants?

Yes, all 100-pin RL78/L1C variants-including R5F110PEAFB#30, R5F110PJAFB#30, and R5F111PEAFB#30-share identical pinouts and package dimensions (LFQFP-100, 14×14 mm, 0.5 mm pitch). Differences lie solely in feature enablement (e.g., USB presence) and memory configuration-not pin function or physical layout-allowing drop-in replacement where USB is unused.
