Product details
Overview
R5F10WLGAFA#30 from Renesas is a 64-pin LQFP (12 × 12 mm, 0.65 mm pitch), 128 KB Flash, 8 KB RAM, RL78/L13 16-bit MCU with integrated LCD controller/driver (36 segment / 4 common outputs), ultra-low power operation (71 μA/MHz active, 0.61 μA RTC+LVD standby), and 24 MHz max CPU speed - designed for battery-powered LCD-based consumer instrumentation.
For engineers reviewing the R5F10WLGAFA#30 datasheet, R5F10WLGAFA#30 pinout, R5F10WLGAFA#30 application, or R5F10WLGAFA#30 equivalent, this page delivers verified electrical specs, validated 64-pin LQFP terminal mapping, real-world LCD timing constraints, and direct alternative part comparisons for rapid embedded design validation and BOM optimization.
Technical Context
The R5F10WLGAFA#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and 1 MB address space. It supports dual-clock domains: high-speed main system clock (up to 24 MHz via on-chip oscillator or external crystal) and independent 32.768 kHz subsystem clock for RTC2 and low-power modes.
Its integrated LCD controller supports internal voltage boosting, capacitor-split, or external resistor-divider biasing methods, with programmable segment/common drive capability and dedicated VL1–VL4 power rails. The device includes two comparators with selectable internal/external reference inputs and full peripheral I/O redirection via PIOR register.
