Product details
Overview
R5F10WLCAFA#30 from Renesas is a 64-pin LQFP (12 × 12 mm, 0.65 mm pitch), 16 KB flash, 1 KB RAM, RL78/L13 16-bit microcontroller with integrated LCD controller/driver (36 segment / 4 common outputs), ultra-low power operation (71 μA/MHz active, 0.61 μA RTC+LVD standby), and 1.6–5.5 V supply - designed for battery-powered LCD display systems in consumer metering and portable instrumentation.
For engineers reviewing the R5F10WLCAFA#30 datasheet, R5F10WLCAFA#30 pinout, R5F10WLCAFA#30 application, or R5F10WLCAFA#30 equivalent, this page delivers verified electrical specs, validated 64-pin LQFP terminal mapping, confirmed LCD timing capabilities, and real-world substitution guidance for cost-optimized, low-power embedded designs.
Technical Context
The R5F10WLCAFA#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting minimum instruction execution times from 0.04167 µs (24 MHz on-chip oscillator) to 30.5 µs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, RTC2 with calendar/alarm/correction, and dual comparators with selectable internal/external reference inputs.
Its peripheral set includes 8-channel 16-bit Timer Array Unit (TAU) with PWM and remote control output, 9-channel 8/10-bit A/D converter (VDD-referenced), 2-channel simplified I²C, 1-channel UART (LIN-capable), and 1-channel CSI (SPI-compatible serial interface), all operating under single-supply 1.6–5.5 V conditions with full -40°C to +85°C ambient rating.

FAQ
What is the maximum operating frequency of the R5F10WLCAFA#30?
The R5F10WLCAFA#30 supports up to 24 MHz using its high-accuracy on-chip oscillator (±1.0% over VDD = 1.8–5.5 V, TA = –20 to +85°C) or 20 MHz with external crystal. At 24 MHz, it delivers 31 DMIPS performance with 71 μA/MHz active current - enabling responsive UI updates while preserving battery life in the R5F10WLCAFA#30.
Does the R5F10WLCAFA#30 support hardware LCD bias generation?
Yes, the R5F10WLCAFA#30 integrates configurable LCD bias circuitry supporting internal voltage boosting, capacitor-split, and external resistor-division methods. This allows direct drive of 36-segment × 4-common LCDs without external charge pumps or bias resistors - a core capability confirmed in the R5F10WLCAFA#30 datasheet Section 1.1 and Block Diagram.
How many analog input channels does the R5F10WLCAFA#30 provide?
The R5F10WLCAFA#30 features a 9-channel, 8/10-bit successive-approximation A/D converter with VDD as reference and optional internal 1.45 V reference. Inputs include ANI0–ANI1, ANI16–ANI25 (10 total pins), but only 9 are routed to the ADC module in the 64-pin variant - confirmed in Table 1-1 and Section 1.6 of the R5F10WLCAFA#30 datasheet.
Is the R5F10WLCAFA#30 pin-compatible with other RL78/L13 variants?
The R5F10WLCAFA#30 shares the same 64-pin LQFP (0.65 mm pitch) package and pinout with all R5F10WLx series parts (e.g., R5F10WLEAFA#30, R5F10WLDAFA#30). Pin functions, power, reset, and peripheral mappings are identical - enabling memory-upgrade compatibility without PCB redesign for the R5F10WLCAFA#30.
What debug interface does the R5F10WLCAFA#30 use?
The R5F10WLCAFA#30 uses Renesas' on-chip debug interface accessible via TOOLRxD/TOOLTxD pins (P17/P00) or dedicated TOOL0 pin (P40). It supports full breakpoint, step, and memory inspection without external JTAG adapter - verified in Section 1.1 (Features) and Figure 1-1 of the R5F10WLCAFA#30 datasheet.
