Product details
Overview
R5F10WLCAFB#30 from Renesas is a 16-bit RL78/L13 microcontroller with integrated LCD controller/driver, 16 KB flash, 4 KB data flash, 1 KB RAM, and ultra-low-power operation (71 μA/MHz active, 0.61 μA RTC+LVD). It features a 24 MHz RL78 CPU core (31 DMIPS), 49 I/O pins, 9-channel 8/10-bit ADC, dual comparators, and supports LCD-based consumer metering and portable HMI applications.
For engineers reviewing the R5F10WLCAFB#30 datasheet, R5F10WLCAFB#30 pinout, R5F10WLCAFB#30 application, or R5F10WLCAFB#30 equivalent, key selection criteria include its 64-pin LFQFP-0.5 mm package, -40°C to +85°C temperature grade, integrated LCD drive capability (36 segment × 4 common), and support for LIN-bus UART, CSI, and I²C interfaces in resource-constrained embedded designs.
Technical Context
The R5F10WLCAFB#30 implements the RL78 CISC CPU core with 3-stage pipeline, 1 MB address space, and configurable instruction timing (0.04167 µs min @ 24 MHz). Its power architecture includes HALT, STOP, and SNOOZE modes, plus on-chip POR and 14-level LVD for robust system reset management across 1.6–5.5 V operation.
Peripherals are tightly integrated for LCD-centric systems: the LCD controller supports internal voltage boosting, capacitor-split, or external resistor division methods; the 16-bit timer array (8 channels) delivers PWM, remote control output (REMOOUT), and RTC2 calendar functions; DMA enables background data flash rewriting during program execution.
