Product details
Overview
R5F10WLGAFA#50 from Renesas is a 64-pin LQFP (12 × 12 mm, 0.65 mm pitch), 128 KB Flash, 8 KB RAM, RL78/L13 16-bit MCU with integrated LCD controller/driver (36 segment / 4 common outputs), ultra-low power operation (71 μA/MHz active, 0.61 μA RTC+LVD), and 24 MHz max CPU speed (31 DMIPS). It targets battery-powered LCD display systems such as smart meters, thermostats, and portable medical devices.
For engineers reviewing the R5F10WLGAFA#50 datasheet, R5F10WLGAFA#50 pinout, R5F10WLGAFA#50 application, or R5F10WLGAFA#50 equivalent, key selection criteria include its 128 KB code flash + 4 KB data flash, dual-voltage comparator with internal reference, 9-channel 8/10-bit ADC, and support for LIN-bus UART - all within a consumer-grade (-40°C to +85°C) temperature range and single 1.6–5.5 V supply.
Technical Context
The R5F10WLGAFA#50 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.04167 µs min @ 24 MHz, 30.5 µs @ 32.768 kHz). Its on-chip voltage regulator supports direct 1.6–5.5 V operation without external LDO, and the HALT/STOP/SNOOZE low-power modes are managed via dedicated control registers and clock gating.
It integrates a full-featured LCD controller/driver with switchable voltage-boosting, capacitor-split, or resistor-divider bias methods, plus programmable segment/common drive capability. The peripheral set includes 8-channel 16-bit Timer Array Unit (TAU), 1-channel 16-bit timer KB20, real-time clock 2 with calendar and alarm, and 4-channel DMA supporting background data flash rewrites.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F10WLGAFA#50?
The R5F10WLGAFA#50 operates at up to 24 MHz using its high-speed on-chip oscillator, delivering 31 DMIPS performance. This benchmark is measured under HS (high-speed main) mode with VDD = 2.7–5.5 V and reflects sustained integer throughput - critical for real-time LCD refresh and sensor processing in the R5F10WLGAFA#50.
Does the R5F10WLGAFA#50 support LIN bus communication, and which UART channel implements it?
Yes, the R5F10WLGAFA#50 supports LIN bus communication via UART1 (RxD1/TxD1 on pins P06/P07), which includes dedicated LINSEL pin control and automatic sync-break detection. This capability is confirmed in the RL78/L13 datasheet Section 1.1 and enables direct integration into automotive body electronics or industrial sub-networks using the R5F10WLGAFA#50.
How many LCD segments and commons does the R5F10WLGAFA#50 support, and what bias methods are available?
The R5F10WLGAFA#50 supports 36 segment outputs and 4 common outputs (or 32 seg / 8 com when configured for higher multiplex ratio). It offers three selectable LCD bias methods: internal voltage boosting, capacitor-split, and external resistance division - all configurable via dedicated control registers in the R5F10WLGAFA#50's LCD module.
What are the power supply requirements and decoupling recommendations for the R5F10WLGAFA#50?
The R5F10WLGAFA#50 requires a single 1.6–5.5 V supply on VDD, with VSS as ground reference. The REGC pin must be connected to VSS via a 0.47–1 μF ceramic capacitor to stabilize the internal voltage regulator - a mandatory design requirement specified on page 5 of the R5F10WLGAFA#50 datasheet to ensure reliable low-power operation.
Can the R5F10WLGAFA#50 perform background data flash writes while executing code from main flash memory?
Yes, the R5F10WLGAFA#50 supports background operation (BGO) for data flash writes: instructions can be fetched and executed from program memory while rewriting the 4 KB data flash area. This feature enables seamless firmware parameter updates and data logging without interrupting real-time tasks - a verified capability documented in Section 1.1 of the R5F10WLGAFA#50 datasheet.
