Product details
Overview
R5F10WLDAFA#10 from Renesas is a 64-pin LQFP (12 × 12 mm, 0.65 mm pitch) 16-bit RL78/L13 microcontroller with integrated LCD controller/driver, 48 KB flash, 1.5 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 down to 71 μA/MHz - optimized for battery-powered LCD display applications including smart meters and portable medical devices.
For engineers reviewing the R5F10WLDAFA#10 datasheet, R5F10WLDAFA#10 pinout, R5F10WLDAFA#10 application, or R5F10WLDAFA#10 equivalent, key selection criteria include its 36-segment/4-common LCD drive capability, dual comparator support, RTC2 with calendar and alarm, and hardware UART/LIN, CSI, and I²C interfaces for sensor and communication subsystem integration.
Technical Context
The R5F10WLDAFA#10 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, 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). Its memory map spans 1 MB address space with banked 8-bit general-purpose registers.
It integrates a dedicated 16-bit Timer KB20 for PWM output, 8-channel TAU timer array with remote control output (REMOOUT), 12-bit interval timer, and real-time clock 2 (RTC2) with 99-year calendar, alarm, and clock correction - all operating independently in STOP/HALT modes while maintaining sub-µA retention current.

FAQ
What is the maximum operating frequency and associated current consumption for R5F10WLDAFA#10?
R5F10WLDAFA#10 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. HALT mode draws just 0.61 μA with RTC and LVD enabled, making it ideal for intermittent wake-up applications.
Does R5F10WLDAFA#10 support hardware UART with LIN physical layer compliance?
Yes, R5F10WLDAFA#10 includes one UART channel explicitly supporting LIN-bus protocol (LIN 2.2A/SAE J2602 compliant) with automatic sync-break detection, checksum calculation, and configurable baud rates. This UART shares pins with CSI and I²C functions and is fully functional in the 64-pin LQFP package.
How many LCD segments and commons does R5F10WLDAFA#10 drive, and what bias methods are supported?
R5F10WLDAFA#10 drives up to 36 segment outputs and 4 common outputs (or 32 segments/8 commons with alternate configuration). It supports three LCD bias methods: internal voltage boosting (for low-VDD operation), capacitor split (for medium contrast), and external resistance division (for precise voltage tuning) - all selectable via control registers.
Can R5F10WLDAFA#10 perform simultaneous ADC conversion and flash programming?
Yes, R5F10WLDAFA#10 supports background operation (BGO) for data flash writes: while rewriting the 4 KB data flash memory, the CPU can execute instructions from code flash. However, code flash self-programming halts CPU execution - ADC conversions must be paused or deferred during code flash erase/write sequences.
What debug interface does R5F10WLDAFA#10 use, and are external debug probes required?
R5F10WLDAFA#10 uses Renesas' on-chip debug interface accessible via TOOLRxD/TOOLTxD pins (P17/P00) - compatible with E2 emulator and E2 studio IDE. No external debug probe is required for basic programming and breakpoint debugging; SWD/JTAG adapters are not supported - only the proprietary single-wire debug channel is implemented.
