Product details
Overview
R5F10WLDAFB#30 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. 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 mode), targeting battery-powered LCD display systems such as smart meters and portable medical devices.
For engineers reviewing the R5F10WLDAFB#30 datasheet, R5F10WLDAFB#30 pinout, R5F10WLDAFB#30 application, or R5F10WLDAFB#30 equivalent, key selection criteria include its 36-segment/4-common LCD drive capability, dual comparator support, 9-channel 10-bit ADC, 8-channel 16-bit timer array, and compatibility with LIN-bus UART for industrial HMI interfaces.
Technical Context
The R5F10WLDAFB#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting configurable instruction execution times from 0.04167 µs (24 MHz on-chip oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its memory subsystem includes 48 KB code flash (1 KB block size), 4 KB background-operable data flash (1M write cycles), and 1.5 KB on-chip RAM.
Peripherals are tightly integrated for LCD-centric applications: the LCD controller supports internal voltage boosting, capacitor split, or external resistor division methods; two comparators offer high-speed/low-speed/window modes with selectable internal/external references; and the 16-bit timer KB20 provides dedicated PWM output for backlight or buzzer control.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F10WLDAFB#30?
The R5F10WLDAFB#30 achieves 31 DMIPS at 24 MHz using its high-speed on-chip oscillator. At this frequency, active current is specified at 71 μA/MHz (≈1.7 mA total), while HALT mode draws 1.2 μA and STOP mode with RTC + LVD active consumes just 0.61 μA - enabling multi-year operation on coin-cell batteries. The device supports multiple clock sources including external crystals (X1/X2) and subsystem clocks (XT1/XT2).
Does the R5F10WLDAFB#30 support true pin-compatible migration within the RL78/L13 family?
Yes - the R5F10WLDAFB#30 shares identical 64-pin LFQFP (0.5 mm pitch) packaging, pinout, and peripheral register mapping with other R5F10WLx variants (e.g., R5F10WLCAFB#30, R5F10WLEAFB#30). This allows hardware reuse across flash/RAM configurations without PCB redesign, provided the target part's memory and peripheral requirements are met per the RL78/L13 User's Manual.
How does the LCD controller in the R5F10WLDAFB#30 handle different display bias requirements?
The R5F10WLDAFB#30 LCD controller supports three bias generation methods: internal voltage boosting (for low-voltage operation), capacitor split (for medium-size displays), and external resistance division (for high-contrast or wide-temp applications). Configuration is done via LCD control registers, and VL1–VL4 pins provide dedicated bias supply outputs - allowing precise tuning of segment/common voltages for optimal contrast across temperature and supply variations.
Can the R5F10WLDAFB#30 execute code while rewriting data flash memory?
Yes - the R5F10WLDAFB#30 supports Background Operation (BGO) for data flash. While rewriting the 4 KB data flash (e.g., storing calibration data or user preferences), the CPU can simultaneously execute instructions from code flash. This ensures uninterrupted real-time operation in applications like medical monitors or smart meters where data logging must not interfere with display refresh or sensor sampling.
What debug and programming interfaces are supported by the R5F10WLDAFB#30?
The R5F10WLDAFB#30 integrates Renesas' on-chip debug functionality accessible via the TOOLRxD/TOOLTxD pins (P17/P00) using the E1/E20 emulator or compatible debuggers. It supports full read/write/erase control of flash memory, real-time variable monitoring, and breakpoint debugging - all without requiring external debug headers. The device also supports self-programming via the boot swap function for robust firmware updates in the field.
