Product details
Overview
R5F10WLCAFB#10 from Renesas is a 64-pin, 16 KB Flash, 1 KB RAM RL78/L13 16-bit microcontroller with integrated LCD controller/driver (36 segment / 4 common), ultra-low power operation (71 μA/MHz active, 0.61 μA RTC+LVD standby), and 1.6–5.5 V supply range - designed for battery-powered LCD display systems in consumer metering and portable instrumentation.
For engineers reviewing the R5F10WLCAFB#10 datasheet, R5F10WLCAFB#10 pinout, R5F10WLCAFB#10 application, or R5F10WLCAFB#10 equivalent, key selection criteria include its on-chip LCD driving capability, 9-channel 8/10-bit ADC, dual comparator support, 3 UART channels (including LIN), and verified 64-pin LFQFP (10 × 10 mm, 0.5 mm pitch) package compatibility.
Technical Context
The R5F10WLCAFB#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.04167 µs min @ 24 MHz high-speed oscillator). It integrates a dedicated LCD controller supporting internal voltage boosting, capacitor split, or external resistor division methods - enabling direct drive of segmented displays without external bias circuitry.
Its peripheral set includes an 8-channel 16-bit Timer Array Unit (TAU) with PWM and remote control output, 12-bit interval timer, RTC2 with calendar and alarm, 2-channel comparator with selectable reference, and 4-channel DMA - all operating under multiple low-power modes (HALT, STOP, SNOOZE) with sub-μA retention current.

FAQ
What is the maximum LCD segment count supported by the R5F10WLCAFB#10?
The R5F10WLCAFB#10 supports up to 36 segment outputs and 4 common outputs in standard configuration. When configured for 8-common operation (using COM0–COM7), it can drive up to 47 segments - confirmed in the RL78/L13 datasheet Section 1.6. This matches the physical pin count and internal RAM allocation for LCD data storage in the R5F10WLCAFB#10 variant.
Does the R5F10WLCAFB#10 include a hardware RTC with calendar function?
Yes, the R5F10WLCAFB#10 integrates Real-Time Clock 2 (RTC2) with full calendar support for 99 years, alarm interrupt, and clock correction - independent of main CPU operation. It runs from the 32.768 kHz subsystem clock (XT1 or low-speed on-chip oscillator) and maintains time in STOP mode with only 0.61 μA current draw, as specified in the R01DS0168EJ0232 datasheet.
Can the R5F10WLCAFB#10 generate IR remote control carrier signals without CPU intervention?
Yes, the R5F10WLCAFB#10 provides dedicated REMOOUT functionality on pin P30, driven by Timer Array Unit channel 3. It supports NEC and RC-5 protocols with programmable carrier frequency (30–60 kHz) and burst timing - enabling hardware-level IR transmission without firmware overhead or timer resource contention.
What is the guaranteed operating temperature range for the R5F10WLCAFB#10?
The R5F10WLCAFB#10 is rated for consumer applications with an operating ambient temperature range of –40°C to +85°C, as indicated by the "A" suffix in its part number and confirmed in Section 1.2 of the R01DS0168EJ0232 datasheet. It is not qualified for industrial-grade (–40°C to +105°C) operation - that requires the "G" suffix variants like R5F10WLCGFB#10.
How many UART interfaces does the R5F10WLCAFB#10 support, and which support LIN protocol?
The R5F10WLCAFB#10 supports three UART interfaces: UART0 (P00/P17), UART1 (P06/P07), and UART2 (P03/P04). Only UART1 includes LIN-bus physical layer support (LINSEL pin) and automatic LIN header detection - enabling direct connection to automotive or industrial LIN networks without external transceivers.
