Product details
Overview
R5F100LLDFB#X0 from Renesas is a 64-pin LFQFP (10 × 10 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit MCU with 512 KB flash, 8 KB data flash, 32 KB RAM, and true low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode) for embedded control in HVAC, motor drives, and smart sensors.
For engineers reviewing the R5F100LLDFB#X0 datasheet, R5F100LLDFB#X0 pinout, R5F100LLDFB#X0 application, or R5F100LLDFB#X0 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, -40°C to +85°C industrial temperature grade (D), integrated RTC with calendar/alarm, 10-bit 26-channel ADC, and dual SPI/I²C/UART interfaces supporting sensor fusion and actuator control.
Technical Context
The R5F100LLDFB#X0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode), enabling dynamic power/performance scaling across wake-up, measurement, and communication phases.
It integrates a 16-bit timer array (16 channels), real-time clock with calendar and clock correction, watchdog timer with dedicated low-speed oscillator, and DMA controller (4 channels) for zero-CPU-overhead peripheral transfers-critical for deterministic timing in closed-loop control systems.
