Product details
Overview
R5F10WLAAFA#50 from Renesas is a 16-bit RL78/L13 microcontroller with integrated LCD controller/driver, 16 KB flash, 1 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, supports 24 MHz max CPU frequency (31 DMIPS), and targets battery-powered LCD display applications including smart meters, thermostats, and portable medical devices.
For engineers reviewing the R5F10WLAAFA#50 datasheet, R5F10WLAAFA#50 pinout, R5F10WLAAFA#50 application, or R5F10WLAAFA#50 equivalent, key selection criteria include its 64-pin LQFP-0.65 mm package, 9-channel 8/10-bit ADC, dual comparator, 8-channel 16-bit timer array, and support for UART, CSI, and I²C interfaces in a single-chip LCD solution.
Technical Context
The R5F10WLAAFA#50 implements the RL78 CISC core with 3-stage pipeline, 1 MB address space, and configurable instruction timing (0.04167 µs min @ 24 MHz, 30.5 µs @ 32.768 kHz). Its power architecture includes HALT, STOP, and SNOOZE modes, plus on-chip POR and 14-level LVD for robust system reset and voltage monitoring.
Peripherals are tightly coupled to the LCD subsystem: 36-segment/4-common LCD driver with selectable voltage-boosting methods, programmable buzzer/clock outputs, and dedicated REMOOUT for infrared carrier generation. The 4-channel DMA enables background data flash rewriting (1M write cycles) while executing code from flash.
