Product details
Overview
R5F104LLAFB#30 from Renesas is a 64-pin LFQFP (0.5 mm pitch), 512 KB flash, 32 KB RAM RL78/G14 16-bit MCU operating from 1.6 V to 5.5 V, delivering 44 DMIPS at 32 MHz with ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD mode), used in industrial motor control and battery-powered sensor nodes.
For engineers reviewing the R5F104LLAFB#30 datasheet, R5F104LLAFB#30 pinout, R5F104LLAFB#30 application, or R5F104LLAFB#30 equivalent, key selection considerations include its 64-pin LFQFP-0.5 mm package, integrated RTC with calendar support, dual 10-bit A/D converter (20-channel), 8-channel 16-bit timer array, and LIN-capable UART interfaces for embedded control systems.
Technical Context
The R5F104LLAFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz), and includes multiply/divide/accumulate instructions with 1 MB address space. It integrates a Data Transfer Controller (DTC) with chain transfer and an Event Link Controller (ELC) enabling 19–26 peripheral event linkings without CPU intervention.
Its mixed-signal subsystem includes an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor, dual 8-bit D/A outputs (0–VDD), two comparators with window/high-speed/low-speed modes, and hardware BCD correction - all operating across the full 1.6–5.5 V supply range and −40°C to +105°C industrial temperature grade (G-grade).
