Product details
Overview
R5F101LLDFA#V0 from Renesas is a 64-pin LQFP-0.65mm, industrial-grade (−40°C to +85°C) RL78/G13 16-bit microcontroller with 512 KB flash, 32 KB RAM, and no data flash memory. It delivers 41 DMIPS at 32 MHz, operates from 1.6–5.5 V, and features ultra-low-power modes (66 μA/MHz active, 0.57 μA RTC+LVD), targeting battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101LLDFA#V0 datasheet, R5F101LLDFA#V0 pinout, R5F101LLDFA#V0 application, or R5F101LLDFA#V0 equivalent, key selection criteria include its 64-pin LQFP package, absence of on-chip data flash, industrial temperature rating, real-time clock with calendar, and integrated 10-bit ADC with 26-channel analog input capability.
Technical Context
The R5F101LLDFA#V0 implements the RL78 CPU core with a 3-stage CISC 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 general-purpose register banks enabling efficient context switching in interrupt-driven applications.
It integrates dual power domains: a main domain for full-speed operation and a subsystem clock domain for low-power peripherals including RTC, LVD, and key interrupt. The device supports background operation during data flash programming-though R5F101xx variants omit data flash, this architecture enables future scalability within the RL78/G13 family using compatible bootloaders and flash libraries.
