Product details
Overview
R5F100LDGFA#10 from Renesas is a 64-pin LQFP-0.65mm, industrial-grade RL78/G13 16-bit microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, and integrated RTC/LVD. It operates from 1.6–5.5 V, delivers 41 DMIPS at 32 MHz, and achieves ultra-low power consumption (66 μA/MHz active, 0.57 μA in RTC+LVD-only mode), targeting battery-powered industrial sensors and smart metering systems.
For engineers reviewing the R5F100LDGFA#10 datasheet, R5F100LDGFA#10 pinout, R5F100LDGFA#10 application, or R5F100LDGFA#10 equivalent, key selection criteria include its industrial temperature range (−40°C to +105°C), on-chip debug support, self-programmable flash with boot swap, background data flash rewriting (BGO), and hardware multiplier/divider for real-time control math.
Technical Context
The R5F100LDGFA#10 implements the RL78 CPU core-a CISC architecture with 3-stage pipeline-supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its memory map spans 1 MB address space with banked 8-bit general-purpose registers.
It integrates dual-clock domains: a high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz) and a dedicated low-speed oscillator for watchdog and RTC operation. Power management includes HALT, STOP, and SNOOZE modes, with on-chip POR and 14-level LVD for robust reset and voltage monitoring.
