Product details
Overview
R5F100LCDFB#50 from Renesas is a 64-pin LFQFP (10 × 10 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit MCU with 128 KB flash, 8 KB data flash, 12 KB RAM, 32 MHz max CPU speed, and true low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It targets battery-powered industrial sensors, smart meters, and embedded control systems requiring robust timing, analog sensing, and serial connectivity.
For engineers reviewing the R5F100LCDFB#50 datasheet, R5F100LCDFB#50 pinout, R5F100LCDFB#50 application, or R5F100LCDFB#50 equivalent, key selection criteria include its integrated 10-bit 26-channel ADC, real-time clock with calendar/alarm, LIN-capable UARTs, and support for HALT/STOP/SNOOZE low-power modes in -40°C to +85°C industrial environments.
Technical Context
The R5F100LCDFB#50 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction execution time (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes up to 16× 16-bit timers, 3× I²C channels, 4× UART/LIN interfaces, 2–8× CSI/SPI channels, DMA controller (4 channels), and hardware multiplier/divider. The device supports background data flash rewriting (BGO) and self-programming with boot swap and flash shield window functions.
