Product details
Overview
R5F10WLGAFB#YW from Renesas is a 64-pin RL78/L13 16-bit microcontroller with integrated LCD controller/driver, 128 KB flash, 8 KB RAM, and 4 KB data flash. It operates from 1.6 V to 5.5 V, achieves 31 DMIPS at 24 MHz, and delivers ultra-low power consumption (71 μA/MHz active, 0.61 μA in RTC+LVD STOP mode), targeting battery-powered LCD display systems such as smart meters and portable medical devices.
For engineers reviewing the R5F10WLGAFB#YW datasheet, R5F10WLGAFB#YW pinout, R5F10WLGAFB#YW application, or R5F10WLGAFB#YW equivalent, key selection criteria include its 36-segment/4-common LCD drive capability, dual comparator support with internal reference, 9-channel 10-bit ADC, UART/LIN-capable serial interfaces, and 64-pin LFQFP (10 × 10 mm, 0.5 mm pitch) package for space-constrained designs.
Technical Context
The R5F10WLGAFB#YW implements the RL78 CPU core-a CISC architecture with 3-stage pipeline and configurable instruction timing (0.04167 µs min @ 24 MHz, 30.5 µs @ 32.768 kHz). It integrates a dedicated 16-bit timer KB20 for high-accuracy PWM output and supports background data flash rewriting via BGO while executing code from program memory.
Its LCD controller supports three voltage generation methods (internal boosting, capacitor split, external resistor division) and drives up to 36 segment lines with 4 common outputs. The MCU includes two comparators with selectable internal/external references, programmable clock/buzzer outputs, and hardware key interrupt support across KR0–KR7 pins for touch-key interfaces.

FAQ
What is the maximum LCD segment count supported by the R5F10WLGAFB#YW?
The R5F10WLGAFB#YW supports up to 36 segment outputs and 4 common outputs in standard configuration. When configured for 8-common operation (using COM4–COM7 as segments), it delivers 32 segment outputs. This matches the 64-pin package's physical I/O constraints and is confirmed in the RL78/L13 datasheet Section 1.6.
Does the R5F10WLGAFB#YW support background data flash rewriting while executing code?
Yes, the R5F10WLGAFB#YW supports Background Operation (BGO) for data flash. Instructions can be fetched and executed from code flash memory while simultaneously rewriting the 4 KB data flash-enabling seamless firmware updates and parameter storage without halting application execution.
What are the valid operating voltage ranges and temperature grades for the R5F10WLGAFB#YW?
The R5F10WLGAFB#YW is rated for 1.6 V to 5.5 V supply voltage and operates over -40°C to +85°C ambient temperature. It belongs to the "A" grade (Consumer applications) per Renesas part numbering, and its electrical specifications are validated across this full range per datasheet Section 2.
How many UART channels does the R5F10WLGAFB#YW include, and which support LIN bus?
The R5F10WLGAFB#YW includes three UART channels. UART2 (RxD2/TxD2 on P03/P04) explicitly supports LIN bus protocol per the RL78/L13 datasheet Section 1.1 Features and Section 1.6 Outline of Functions. UART0 and UART1 provide standard asynchronous communication only.
Can the R5F10WLGAFB#YW generate precise audio tones using its built-in peripherals?
Yes, the R5F10WLGAFB#YW includes a programmable clock/buzzer output controller with eight selectable frequencies (256 Hz to 32.768 kHz) derived from either main or subsystem clocks. This enables direct piezo buzzer drive without external timers or DACs-verified in Section 1.1 Features and Section 1.6 of the datasheet.
