Product details
Overview
R5F104PLGFB#30 from Renesas is a 100-pin LFQFP, 0.5 mm pitch, industrial-grade (G) 16-bit RL78/G14 microcontroller with 384 KB flash, 32 KB RAM, and 8 KB data flash. It operates from 1.6–5.5 V, delivers 44 DMIPS at 32 MHz, and supports ultra-low-power modes (0.60 μA RTC+LVD). It targets embedded control in HVAC, motor drives, and smart sensors.
For engineers reviewing the R5F104PLGFB#30 datasheet, R5F104PLGFB#30 pinout, R5F104PLGFB#30 application, or R5F104PLGFB#30 equivalent, key selection criteria include its 100-pin LFQFP-0.5 mm package, -40°C to +105°C industrial temperature rating, integrated RTC with calendar, 12-bit ADC (20 channels), and hardware event-linking via ELC for deterministic peripheral coordination.
Technical Context
The R5F104PLGFB#30 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). It integrates a Data Transfer Controller (DTC) with chain transfer and an Event Link Controller (ELC) enabling direct peripheral-to-peripheral signal routing without CPU intervention.
It features dual-clock domains: high-speed on-chip oscillator (selectable up to 64 MHz ±1.0%) and subsystem clock (32.768 kHz), enabling simultaneous high-performance computation and ultra-low-power real-time monitoring. The device includes background operation (BGO) for data flash rewriting while executing code from program memory.
