Product details
Overview
R5F10WMAAFA#30 from Renesas is an RL78/L13 80-pin LQFP microcontroller with integrated LCD controller/driver, 64 KB flash, 4 KB data flash, 4 KB RAM, and true low-power operation (71 μA/MHz active, 0.61 μA in RTC+LVD STOP mode). It operates from 1.6 V to 5.5 V, delivers 31 DMIPS at 24 MHz, and targets battery-powered LCD-based consumer devices such as smart meters and portable medical displays.
For engineers reviewing the R5F10WMAAFA#30 datasheet, R5F10WMAAFA#30 pinout, R5F10WMAAFA#30 application, or R5F10WMAAFA#30 equivalent, key selection criteria include its 51-segment/4-common LCD drive capability, 12-channel 8/10-bit ADC, dual comparator with internal reference, UART2 + LIN support, and 80-pin LQFP (14 × 14 mm, 0.65 mm pitch) package with -40°C to +85°C temperature grade.
Technical Context
The R5F10WMAAFA#30 implements the RL78 CPU core - a CISC architecture with 3-stage pipeline, 1 MB address space, and configurable instruction timing (0.04167 µs min @ 24 MHz HS oscillator or 30.5 µs @ 32.768 kHz subsystem clock). It integrates a dedicated 16-bit timer KB20 for high-accuracy PWM and supports background data flash rewriting via BGO.
Its power management includes HALT, STOP, and SNOOZE modes, on-chip POR/LVD (14-level selectable), and voltage regulator with REGC capacitor support. The LCD controller supports three bias methods (internal boost, capacitor split, external resistor division) and drives up to 51 segments with 4 or 8 commons depending on configuration.

FAQ
What is the maximum LCD segment count supported by the R5F10WMAAFA#30?
The R5F10WMAAFA#30 supports up to 51 segment outputs and 4 or 8 common outputs, enabling multiplexed drive of LCDs with up to 204 (51×4) or 408 (51×8) segments. Configuration depends on selected bias method (capacitor split or external resistor division) and COM count setting in the LCD control registers.
Does the R5F10WMAAFA#30 support LIN bus communication?
Yes, the R5F10WMAAFA#30 supports LIN bus communication through UART2, which includes LINSEL functionality for automatic sync-break detection and LIN protocol framing. This enables direct integration into automotive body electronics or industrial sub-networks without external transceivers.
What is the operating voltage range and temperature grade of the R5F10WMAAFA#30?
The R5F10WMAAFA#30 operates from 1.6 V to 5.5 V over an ambient temperature range of –40°C to +85°C, meeting consumer-grade specifications. Its low-voltage capability down to 1.6 V allows compatibility with single-cell Li-ion or multi-cell alkaline battery systems.
How does the R5F10WMAAFA#30 achieve ultra-low power consumption in STOP mode?
The R5F10WMAAFA#30 achieves 0.61 μA STOP mode current by retaining only the real-time clock (RTC2) and low-voltage detector (LVD) circuits while halting the CPU, flash, and most peripherals. The 32.768 kHz subsystem clock remains active to maintain calendar accuracy and wake-on-interrupt capability.
Can the R5F10WMAAFA#30 perform simultaneous ADC conversion and data flash programming?
Yes-the R5F10WMAAFA#30 supports Background Operation (BGO) for data flash, allowing full CPU instruction execution-including ADC sampling and result processing-while data flash is being rewritten. This enables seamless firmware updates or parameter storage without interrupting real-time tasks.
