Product details
Overview
R5F110PEAFB#10 from Renesas is a 100-pin LFQFP 32-bit RL78/L1C microcontroller with integrated LCD controller/driver (56-segment/8-common), 12-bit A/D converter (12-channel, 2.4–3.6 V range), USB 2.0 function controller (full-speed/low-speed), 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 meters, industrial HMI panels, and portable instrumentation.
For engineers reviewing the R5F110PEAFB#10 datasheet, R5F110PEAFB#10 pinout, R5F110PEAFB#10 application, or R5F110PEAFB#10 equivalent, key selection criteria include USB 2.0 function support, 100-pin QFP package with LCD segment/com drivers, 12-bit ADC accuracy at 2.4–3.6 V, ultra-low power STOP/HALT modes, and Renesas' RL78 core instruction timing flexibility (0.04167–30.5 μs).
Technical Context
The R5F110PEAFB#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing across 24 MHz (high-speed on-chip oscillator or PLL) to 32.768 kHz (subsystem clock). It integrates a dedicated USB voltage regulator (UREGC/UVBUS pins), hardware LCD controller supporting internal boosting/capacitor-split/external resistor division, and dual comparator channels with selectable reference sources.
Its peripheral set includes 11× 16-bit timers, real-time clock 2 (99-year calendar, alarm, correction), data transfer controller (DTC) with chain transfer, event link controller (ELC) for 30–31 event routing, and five I²C-compatible interfaces - all operating within 1.6–3.6 V supply and -40 to +85°C ambient (Consumer grade A).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F110PJAFB#10 | Same 100-pin LFQFP package, identical peripherals, but 256 KB flash + 16 KB RAM (same as R5F110PEAFB#10); differs only in factory-programmed security settings and debug lock state | No functional difference in LCD, USB, or ADC usage; identical timing and power behavior | Select R5F110PJAFB#10 only if specific debug access restrictions or flash shield window configuration is required |
| R5F111PEAFB#10 | Pin-compatible 100-pin variant without USB 2.0 controller; retains same flash/RAM, LCD, ADC, and low-power features | Cannot support USB-based firmware update or PC data export; requires external interface (e.g., UART-to-USB bridge) for host connectivity | Choose R5F111PEAFB#10 when USB is unnecessary and BOM cost reduction is prioritized over native USB integration |
Compared with R5F110PJAFB#10, the R5F110PEAFB#10 offers identical functionality but with default debug enablement and standard flash protection; versus R5F111PEAFB#10, it adds USB 2.0 function capability at no pin-count or power penalty-enabling direct host communication without external silicon.

FAQ
What is the maximum LCD segment count supported by the R5F110PEAFB#10?
The R5F110PEAFB#10 supports up to 56 segment outputs and 8 common outputs, enabling configurations such as 56×8 (448 segments) or 56×4 (224 segments) depending on multiplex ratio. This is confirmed in the RL78/L1C datasheet Section 1.1 under "LCD controller/driver" and verified in the 100-pin pin configuration diagram (Page 9).
Does the R5F110PEAFB#10 support 12-bit A/D conversion across its full 1.6–3.6 V supply range?
No-the R5F110PEAFB#10's 12-bit A/D converter requires VDD ≥ 2.4 V per the datasheet (Section 1.1). At 1.6–2.3 V, only 8/10-bit resolution is available. This voltage dependency is explicitly stated and must be accounted for in low-voltage battery designs.
What USB speed modes does the R5F110PEAFB#10 support, and is external PHY required?
The R5F110PEAFB#10 supports both full-speed (12 Mbps) and low-speed (1.5 Mbps) USB 2.0 operation and includes an integrated USB voltage regulator and transceiver-no external PHY or level-shifting components are needed. UREGC, UVBUS, UDM, and UDP pins connect directly per datasheet Caution 2 (Page 9).
How many timer channels are available on the R5F110PEAFB#10, and what are their bit widths?
The R5F110PEAFB#10 provides 11 independent 16-bit timer channels (TI00/TO00 through TI07/TO07 plus TI06/TO06 and TI07/TO07), one 12-bit interval timer, and one real-time clock 2 with calendar function-all documented in Section 1.1 "Timers" and confirmed in the block diagram (Page 14).
Is the R5F110PEAFB#10 pin-compatible with any non-USB RL78/L1C variants?
Yes-the R5F110PEAFB#10 is pin-compatible with the R5F111PEAFB#10 (non-USB variant), sharing identical 100-pin LFQFP mechanical dimensions, power/ground pin locations, and peripheral I/O mapping. Only USB-specific pins (UREGC, UVBUS, UDM, UDP) are unused in the R5F111PEAFB#10, as confirmed in Sections 1.3.5 and 1.3.6 of the datasheet.
