Product details
Overview
R5F10WLAAFB#30 from Renesas is a 64-pin RL78/L13 16-bit microcontroller with integrated LCD controller/driver, 16 KB flash, 4 KB data flash, 1 KB RAM, and ultra-low-power operation (71 μA/MHz active, 0.61 μA in RTC+LVD mode). It supports 1.6–5.5 V supply, operates from –40°C to +85°C, and targets battery-powered LCD displays in consumer metering and portable HMI devices.
For engineers reviewing the R5F10WLAAFB#30 datasheet, R5F10WLAAFB#30 pinout, R5F10WLAAFB#30 application, or R5F10WLAAFB#30 equivalent, key selection criteria include its 36-segment/4-common LCD drive capability, dual comparator inputs, 9-channel 8/10-bit ADC, 8-channel 16-bit timer array, and support for LIN-bus UART - all within a compact 10 × 10 mm LFQFP-64 package.
Technical Context
The R5F10WLAAFB#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling 31 DMIPS at 24 MHz. Its power management includes HALT, STOP, and SNOOZE modes, plus on-chip POR and 14-level LVD with interrupt/reset selectability.
Peripherals are tightly integrated for LCD-centric systems: the LCD controller supports internal voltage boosting, capacitor split, or external resistor division; the 2-channel comparator offers high-speed, low-speed, and window modes; and the 4-channel DMA enables background data flash rewriting during program execution.

FAQ
What is the maximum LCD segment count supported by R5F10WLAAFB#30?
R5F10WLAAFB#30 supports up to 36 segment outputs and 4 common outputs (or 32 segments with 8 commons), as confirmed in the RL78/L13 datasheet Section 1.1 and Table 1-1. This configuration drives standard alphanumeric LCD modules used in utility meters and portable instruments without external segment drivers.
Does R5F10WLAAFB#30 support LIN bus communication?
Yes, R5F10WLAAFB#30 supports LIN bus communication via its UART0 channel, as explicitly stated in the "Serial interface" section of the datasheet (Page 1, Feature List) and confirmed in Section 1.6 under "Serial interface" for 64-pin products. The LINSEL pin is not present on this variant, but LIN protocol is implemented in firmware using UART0's break-detection and sync-field timing capabilities.
What are the power supply requirements for stable operation of R5F10WLAAFB#30?
R5F10WLAAFB#30 requires a single 1.6–5.5 V supply across VDD–VSS, with mandatory 0.47–1 μF decoupling capacitor between REGC and VSS (per datasheet Page 5, Caution note). Operating outside this range or omitting the REGC capacitor causes unstable internal voltage regulation and potential LCD driver malfunction or reset anomalies.
Can R5F10WLAAFB#30 perform simultaneous ADC conversion and data flash writing?
Yes, R5F10WLAAFB#30 supports Background Operation (BGO) for data flash, allowing full CPU execution-including ADC conversions-from code flash memory while rewriting data flash. This is documented in Section 1.1 "Data flash memory" and verified in the User's Manual Chapter 3, enabling real-time sensor logging without interrupting measurement cycles.
Is R5F10WLAAFB#30 pin-compatible with other RL78/L13 64-pin variants?
Yes, all RL78/L13 64-pin variants-including R5F10WLAAFB#30, R5F10WLCAFB#30, and R5F10WLDAFB#30-share identical LFQFP-64 pinouts and electrical characteristics per Section 1.3.1 and Table 1-1 of the datasheet. Only flash/RAM sizes and temperature grades differ, making them hardware-compatible drop-in upgrades.
