Overview
R5F10WLGAFB#V0 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, delivers 31 DMIPS at 24 MHz, and achieves 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#V0 datasheet, R5F10WLGAFB#V0 pinout, R5F10WLGAFB#V0 application, or R5F10WLGAFB#V0 equivalent, key selection criteria include its 36-segment/4-common LCD drive capability, dual comparator support, 12-channel 10-bit ADC, 3 UARTs (one LIN-capable), and hardware-based remote control carrier output for IR applications.
Technical Context
The R5F10WLGAFB#V0 implements the RL78 CPU core-a CISC architecture with 3-stage pipeline-supporting instruction execution times from 0.04167 µs (24 MHz HS on-chip oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its memory map spans 1 MB address space with banked 8-bit general-purpose registers.
It integrates a dedicated LCD controller supporting internal voltage boosting, capacitor split, or external resistor division methods; a 16-bit timer array unit (8 channels, 7 PWM-capable); real-time clock 2 with calendar and alarm; and a 4-channel DMA controller enabling background data flash rewrites while executing code from program memory.

FAQ
What is the maximum LCD segment count supported by the R5F10WLGAFB#V0?
The R5F10WLGAFB#V0 supports up to 36 segment outputs and 4 common outputs (36×4 configuration), expandable to 32×8 using alternate biasing modes. This matches standard 4-digit alphanumeric LCD modules used in utility meters and small appliances. The device does not support dot-matrix or graphical LCDs.
Does the R5F10WLGAFB#V0 include hardware support for infrared remote control transmission?
Yes, the R5F10WLGAFB#V0 includes a dedicated REMOOUT pin (P30) that generates precise 30–60 kHz carrier signals for IR protocols like NEC and RC-5. This hardware block operates independently of the CPU, enabling low-power, jitter-free transmission without consuming instruction cycles or timer resources.
What are the voltage detector (LVD) threshold options available on the R5F10WLGAFB#V0?
The R5F10WLGAFB#V0 provides 14 programmable LVD threshold levels ranging from 1.67 V to 4.06 V (rising edge) and 1.63 V to 3.98 V (falling edge). These thresholds can trigger either interrupt or reset events, allowing flexible brown-out response strategies-such as graceful shutdown before flash corruption occurs.
Can the R5F10WLGAFB#V0 execute code while rewriting data flash memory?
Yes, the R5F10WLGAFB#V0 supports Background Operation (BGO), allowing full CPU execution-including interrupt handling and peripheral control-while data flash is being rewritten. This enables seamless firmware updates and parameter storage without halting real-time functions like LCD refresh or sensor sampling.
Is an external crystal required for the R5F10WLGAFB#V0 to operate at 24 MHz?
No, the R5F10WLGAFB#V0 features a high-accuracy ±1.0% on-chip oscillator capable of 24 MHz operation across 1.8–5.5 V and -40°C to +85°C. An external crystal is optional and only needed if tighter frequency stability (<±0.1%) or synchronization to external clocks is required.
