Product details
Overview
R5F10WLDAFB#10 from Renesas is a 64-pin RL78/L13 16-bit microcontroller with integrated LCD controller/driver, 48 KB flash, 1.5 KB RAM, and 4 KB data flash-designed for ultra-low-power LCD-based applications such as smart meters and portable medical devices. It operates from 1.6 V to 5.5 V, delivers 31 DMIPS at 24 MHz, and achieves as low as 71 μA/MHz active current and 0.61 μA in RTC+LVD STOP mode.
For engineers reviewing the R5F10WLDAFB#10 datasheet, R5F10WLDAFB#10 pinout, R5F10WLDAFB#10 application, or R5F10WLDAFB#10 equivalent, this page provides verified technical context, validated pin functions, real-world use cases for LCD HMI systems, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The R5F10WLDAFB#10 implements the RL78 CPU core-a CISC architecture with 3-stage pipeline and 1 MB address space-supporting configurable instruction execution times from 0.04167 µs (24 MHz high-speed on-chip oscillator) to 30.5 µs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, real-time clock 2 with calendar and alarm, and dual comparators with selectable internal/external reference inputs.
Its peripheral set includes 8-channel 16-bit timer array unit (TAU), 4-channel DMA, UART/LIN-capable serial interfaces (3 UART channels total), simplified SPI (CSI), I²C, and an 8/10-bit A/D converter with up to 9 analog inputs. The LCD controller supports 36 segment × 4 common outputs using internal voltage boosting or external resistor division.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R5F10WLDAFB#10?
The R5F10WLDAFB#10 achieves 24 MHz operation using its high-accuracy ±1.0% on-chip oscillator, delivering 31 DMIPS performance. At this speed and VDD = 3.3 V, typical active current is 71 μA/MHz-so ~1.7 mA total. This enables responsive LCD updates and sensor polling while maintaining sub-2 mA peak draw in portable designs.
Does the R5F10WLDAFB#10 support hardware-based LCD bias generation without external components?
Yes, the R5F10WLDAFB#10 integrates a programmable LCD voltage booster circuit. When configured for internal voltage boosting, it generates required segment/common bias voltages directly from VDD-eliminating external charge pumps or resistor networks for standard 3–5 V LCD panels.
How many UART interfaces does the R5F10WLDAFB#10 include, and which support LIN physical layer?
The R5F10WLDAFB#10 includes three UART channels. UART2 (RxD2/TxD2 on P03/P04) is explicitly LIN-bus capable per the datasheet, supporting ISO 17987-4 compliant signaling for automotive body electronics and industrial control networks.
Can the R5F10WLDAFB#10 perform simultaneous ADC conversion and data flash writes?
Yes-the R5F10WLDAFB#10 supports background operation (BGO) for data flash. While executing code from main flash, it can rewrite 4 KB data flash memory using VDD = 1.8–5.5 V, enabling real-time logging (e.g., sensor history) without interrupting ADC sampling or LCD refresh.
What is the pin-compatible upgrade path from the R5F10WLDAFB#10 to higher memory capacity?
The R5F10WLEAFB#10 is pin-compatible with the R5F10WLDAFB#10-same 64-pin LFQFP package, identical pinout, and identical peripheral mapping. It upgrades flash from 48 KB to 64 KB and RAM from 1.5 KB to 2 KB, allowing seamless firmware expansion without PCB revision.
