Product details
Overview
R5F10WLCGFB#50 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 delivering 31 DMIPS, operates from 1.6–5.5 V, and targets battery-powered LCD-based instrumentation and industrial HMI panels.
For engineers reviewing the R5F10WLCGFB#50 datasheet, R5F10WLCGFB#50 pinout, R5F10WLCGFB#50 application, or R5F10WLCGFB#50 equivalent, key selection criteria include its 64-pin LFQFP-0.5 mm package, industrial-grade −40°C to +105°C temperature rating, on-chip LCD drive capability (up to 36 segment × 4 common), and support for UART, I²C, CSI, and 8-channel 16-bit timer array - all critical for space-constrained, low-power embedded displays.
Technical Context
The R5F10WLCGFB#50 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 and brown-out management in fluctuating supply environments.
Peripherals are tightly coupled to the LCD subsystem: dual comparators feed VCOUT0/VCOUT1 for contrast control; VL1–VL4 pins support internal voltage boosting or external resistor-divider biasing; and 36 segment / 4 common outputs are directly mapped to P0–P7 port pins with flexible remapping via PIOR registers - enabling dynamic segment reassignment without hardware changes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | RL78 16-bit CISC CPU with 3-stage pipeline, 31 DMIPS @ 24 MHz - enables real-time sensor processing and UI rendering in resource-constrained devices. |
