Overview
R5F10WLGAFB#30 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#30 datasheet, R5F10WLGAFB#30 pinout, R5F10WLGAFB#30 application, or R5F10WLGAFB#30 equivalent, this page provides verified technical context, validated pin functions, real-world use cases for LCD-based embedded control, and confirmed alternative parts with documented functional and packaging differences.
Technical Context
The R5F10WLGAFB#30 implements the RL78 CPU core - a CISC architecture with 3-stage pipeline and 1 MB address space - optimized for deterministic real-time response in resource-constrained LCD applications. It integrates dual clock domains: a high-speed on-chip oscillator (selectable up to 24 MHz ±1.0%) and a 32.768 kHz subsystem clock for RTC2 and low-power modes.
Its peripheral set is purpose-built for human-machine interface: 36-segment/4-common LCD driver with internal voltage boosting, 2-channel comparator with selectable reference, 9-channel 8/10-bit ADC, and dedicated key interrupt inputs (KR0–KR7) supporting matrix keypad scanning. All peripherals are accessible via 49 I/O pins, including 12 N-ch open-drain I/Os rated for VDD withstand voltage.

FAQ
What is the maximum operating frequency and associated power consumption of the R5F10WLGAFB#30?
The R5F10WLGAFB#30 achieves 31 DMIPS at 24 MHz using its high-speed on-chip oscillator. At this frequency and VDD = 3.3 V, typical active current is 71 μA/MHz - meaning ~1.7 mA total at 24 MHz. In STOP mode with RTC2 and LVD active, it draws only 0.61 μA, making it ideal for infrequently updated LCD displays.
Does the R5F10WLGAFB#30 support hardware-based LCD bias generation without external components?
Yes. The R5F10WLGAFB#30 integrates an internal voltage boosting circuit for LCD bias, configurable alongside capacitor-split and external resistor-division methods. When using internal boost, only VL1–VL4 and CAPH/CAPL external capacitors are required - no external DC-DC converter or resistor network is needed for basic 36×4 segment operation.
How many UART interfaces does the R5F10WLGAFB#30 provide, and which support LIN bus physical layer?
The R5F10WLGAFB#30 includes three UART channels. UART2 (RxD2/TxD2 on P03/P04) is explicitly LIN-bus capable per the datasheet, supporting LIN 2.2 protocol with automatic sync-break detection and checksum generation - essential for automotive body electronics and industrial sub-networks.
Can the R5F10WLGAFB#30 perform ADC conversions while in low-power STOP mode?
No. ADC operation requires the main system clock domain to be active. However, the R5F10WLGAFB#30 supports SNOOZE mode - a hybrid state where the CPU halts but selected peripherals (including ADC trigger via timer or external interrupt) remain clocked, enabling low-latency wake-up and conversion with sub-10 μs resume time.
What debug interface does the R5F10WLGAFB#30 use, and what pins are required?
The R5F10WLGAFB#30 uses Renesas' on-chip debug interface via the TOOLRxD (P17) and TOOLTxD (P00) pins - compatible with E2 emulator and E2 studio IDE. These pins double as UART0 I/O, allowing shared use during development and production, eliminating need for dedicated debug headers.
