Product details
Overview
R5F10WLFAFB#30 from Renesas is a 64-pin RL78/L13 16-bit microcontroller with integrated LCD controller/driver, 64 KB flash, 4 KB data flash, 4 KB RAM, and ultra-low power operation (71 μA/MHz active, 0.61 μA in RTC+LVD mode). It supports 1.6–5.5 V supply, −40 to +85°C operation, and targets battery-powered LCD displays in consumer metering and portable instrumentation.
For engineers reviewing the R5F10WLFAFB#30 datasheet, R5F10WLFAFB#30 pinout, R5F10WLFAFB#30 application, or R5F10WLFAFB#30 equivalent, key selection criteria include its 36-segment/4-common LCD drive capability, dual comparator inputs, 9-channel 10-bit ADC, UART/LIN support, and LFQFP-64 (10 × 10 mm, 0.5 mm pitch) package compatibility with space-constrained designs.
Technical Context
The R5F10WLFAFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.04167 µs min @ 24 MHz). It integrates a dedicated 16-bit timer KB20 for PWM output and a real-time clock 2 with calendar, alarm, and correction functions - all operating independently of the main CPU clock.
Its power management includes HALT, STOP, and SNOOZE modes, on-chip POR/LVD with 14-level voltage detection, and a high-accuracy ±1.0% on-chip oscillator (1–24 MHz selectable). The LCD controller supports internal voltage boosting, capacitor split, and external resistor division methods for flexible segment bias generation.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F10WLFAFB#30?
The R5F10WLFAFB#30 operates up to 24 MHz using its high-speed on-chip oscillator with ±1.0% accuracy. At this frequency and 3.3 V supply, typical active current is 71 μA per MHz - resulting in ~1.7 mA total. In STOP mode with RTC + LVD enabled, it draws only 0.61 μA, enabling decade-long battery operation in metering applications.
Does the R5F10WLFAFB#30 support hardware LCD bias generation without external components?
Yes, the R5F10WLFAFB#30 integrates an LCD controller that supports three bias generation methods: internal voltage boosting, capacitor split, and external resistance division. When using the internal boosting method, no external charge pump or resistors are required - only the VL1–VL4 supply pins and CAPH/CAPL capacitors must be connected per the datasheet guidelines.
How many analog input channels does the R5F10WLFAFB#30 have, and what is their resolution?
The R5F10WLFAFB#30 features a 10-bit successive-approximation ADC with 9 analog input channels (ANI0, ANI1, ANI16–ANI25). It supports VDD-referenced conversion and includes an internal 1.45 V reference voltage source usable for precision measurements independent of supply variation.
Can the R5F10WLFAFB#30 perform firmware updates in the field without halting application code?
Yes, the R5F10WLFAFB#30 supports background operation (BGO) for data flash writes: instructions can execute from program memory while rewriting the 4 KB data flash. Combined with boot swap functionality and flash shield window protection, this enables secure, seamless over-the-air or local firmware updates without interrupting real-time tasks like LCD refresh or sensor sampling.
What debug and programming interfaces are available on the R5F10WLFAFB#30?
The R5F10WLFAFB#30 includes a full on-chip debug interface accessible via the TOOLRxD/TOOLTxD pins (P17/P00) and TOOL0 (P40). It supports Renesas E2 emulator and E2 studio IDE for full-featured debugging, flash programming, and real-time trace - no external JTAG adapter is required for development or production programming.
