Product details
Overview
R5F100LDAFB#10 from Renesas is a 64-pin LFQFP-packaged RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, 32 MHz max CPU speed, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), designed for industrial control, sensor nodes, and battery-powered HMI systems.
For engineers reviewing the R5F100LDAFB#10 datasheet, R5F100LDAFB#10 pinout, R5F100LDAFB#10 application, or R5F100LDAFB#10 equivalent, key selection criteria include its integrated real-time clock with calendar/alarm, 10-bit 26-channel ADC with internal temperature sensor, dual UART/LIN support, and hardware DMA for deterministic peripheral-to-memory transfers in resource-constrained embedded designs.
Technical Context
The R5F100LDAFB#10 implements the RL78 CPU core with a 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), and features an on-chip high-accuracy ±1.0% oscillator across 1.8–5.5 V and –40°C to +85°C.
It integrates a 16-bit timer array (16 channels), 12-bit interval timer, watchdog timer, and real-time clock with calendar function, alarm, and clock correction-enabling precise timekeeping without external components while maintaining sub-μA standby current via dedicated low-speed oscillator.
