Product details
Overview
R5F10WMDAFB#30 from Renesas is an 80-pin RL78/L13 16-bit microcontroller with integrated LCD controller/driver, 32 KB code flash, 4 KB data flash, 1.5 KB RAM, and ultra-low power operation (71 μA/MHz active, 0.61 μA RTC+LVD). It supports 1.6–5.5 V supply, -40°C to +85°C ambient, and targets battery-powered LCD display systems such as smart meters and portable medical devices.
For engineers reviewing the R5F10WMDAFB#30 datasheet, R5F10WMDAFB#30 pinout, R5F10WMDAFB#30 application, or R5F10WMDAFB#30 equivalent, key selection criteria include its 51-segment/8-common LCD drive capability, dual UART + I²C + CSI interfaces, 12-channel 10-bit ADC, and hardware RTC with calendar and alarm-critical for human-interface and energy-conscious embedded designs.
Technical Context
The RL78/L13 core implements a CISC architecture with 3-stage pipeline, delivering 31 DMIPS at 24 MHz while supporting configurable instruction timing from 0.04167 µs (24 MHz HS oscillator) to 30.5 µs (32.768 kHz subsystem clock). Its memory-mapped I/O and peripheral redirection register (PIOR) enable flexible pin assignment across 65 GPIOs.
Power management includes HALT, STOP, and SNOOZE modes, plus on-chip POR and 14-level LVD with interrupt/reset selectability. The integrated LCD controller supports three voltage-boost methods (internal capacitor split, external resistor division, internal boosting), enabling direct drive of segmented displays without external bias circuitry.
