Product details
Overview
R5F10WMCGFB#50 from Renesas is an 80-pin RL78/L13 16-bit microcontroller with integrated LCD controller/driver, 96 KB flash, 4 KB data flash, 6 KB RAM, and ultra-low-power operation (71 μA/MHz active, 0.61 μA in RTC+LVD mode). It supports 1.6–5.5 V supply, −40 to +105°C industrial temperature range, and targets battery-powered LCD-based instrumentation such as smart meters and portable medical displays.
For engineers reviewing the R5F10WMCGFB#50 datasheet, R5F10WMCGFB#50 pinout, R5F10WMCGFB#50 application, or R5F10WMCGFB#50 equivalent, key selection criteria include its 51-segment/8-common LCD drive capability, dual UART + LIN support, 12-channel 10-bit ADC, and hardware RTC with calendar and alarm-critical for energy metering and HMI-embedded industrial controls.
Technical Context
The R5F10WMCGFB#50 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction execution time (0.04167 µs at 24 MHz high-speed on-chip oscillator or 30.5 µs at 32.768 kHz subsystem clock). Its memory map spans 1 MB address space with banked 8-bit general-purpose registers.
It integrates a dedicated LCD controller supporting internal voltage boosting, capacitor-split, or external resistor division methods; a 12-bit interval timer; real-time clock 2 with 99-year calendar and correction function; and two independent comparators with selectable internal/external reference inputs.
