Product details
Overview
R5F104GLGFB#10 from Renesas is a 48-pin LFQFP, 128 KB flash, 12 KB RAM, RL78/G14 16-bit MCU operating at 32 MHz with 44 DMIPS, ultra-low power (66 μA/MHz active, 0.60 μA RTC+LVD), and industrial-grade −40°C to +105°C operation for embedded control in motor drives and sensor nodes.
For engineers reviewing the R5F104GLGFB#10 datasheet, R5F104GLGFB#10 pinout, R5F104GLGFB#10 application, or R5F104GLGFB#10 equivalent, key selection factors include its 128 KB code flash with data flash shield window, dual UART/LIN support, 12-channel 16-bit TAU timer, integrated RTC with calendar/alarm, and hardware DTC/ELC for deterministic peripheral event handling.
Technical Context
The R5F104GLGFB#10 implements the RL78 CPU core with 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), plus multiply/divide/accumulate instructions and 1 MB address space.
It integrates a configurable 19–26-event Event Link Controller (ELC) for direct peripheral triggering without CPU intervention, and a Data Transfer Controller (DTC) supporting normal, repeat, block, and chain transfer modes activated by interrupt sources - enabling low-latency, low-CPU-overhead data movement.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104GLGFB#10?
The R5F104GLGFB#10 operates at up to 32 MHz with a measured performance of 44 DMIPS. This rating is achieved using the RL78 CPU core's 3-stage pipeline and optimized instruction set, enabling efficient execution of real-time control algorithms such as motor commutation or sensor fusion without requiring external acceleration.
Does the R5F104GLGFB#10 support background data flash rewriting while executing code from main flash memory?
Yes, the R5F104GLGFB#10 supports Background Operation (BGO) for data flash. It can execute instructions from code flash memory while simultaneously rewriting the 4 KB data flash area - a critical capability for non-disruptive firmware parameter updates or cyclic data logging in always-on systems.
What are the supported crystal frequencies for the R5F104GLGFB#10's main and subsystem clocks?
The R5F104GLGFB#10 supports an external 1–20 MHz crystal on P121/P122 for the main system clock and a 32.768 kHz crystal on the same pins (or dedicated XT1/XT2) for the subsystem clock driving the RTC. The high-accuracy ±1.0% on-chip oscillator (64–1 MHz selectable) eliminates need for external crystals in cost-sensitive designs.
How many UART/LIN channels does the R5F104GLGFB#10 integrate, and are they hardware-independent?
The R5F104GLGFB#10 integrates three UART/LIN channels, each with dedicated hardware logic and independent baud rate generators. They operate concurrently without resource contention, supporting simultaneous LIN bus master/slave roles and debug UART alongside application messaging - verified in the RL78/G14 peripheral summary table.
Is the R5F104GLGFB#10 qualified for industrial temperature range, and what is the exact specification?
Yes, the R5F104GLGFB#10 is rated for industrial operation from −40°C to +105°C (suffix "G" denotes this grade). This qualification is confirmed in the ordering information section and applies across all electrical specifications including flash endurance, ADC accuracy, and oscillator stability - making it suitable for under-hood or factory-floor deployments.
