Product details
Overview
R5F104LGGFA#30 from Renesas is a 64-pin LQFP-0.65mm, industrial-grade (−40°C to +105°C) RL78/G14 16-bit MCU with 512 KB flash, 8 KB data flash, 48 KB RAM, 44 DMIPS @ 32 MHz, and ultra-low-power operation (66 μA/MHz active, 0.60 μA RTC+LVD). It targets battery-powered industrial control, sensor nodes, and smart actuators requiring robust timing, analog integration, and low-voltage operation down to 1.6 V.
For engineers reviewing the R5F104LGGFA#30 datasheet, R5F104LGGFA#30 pinout, R5F104LGGFA#30 application, or R5F104LGGFA#30 equivalent, key selection considerations include its 64-pin LQFP package, G-grade temperature rating, integrated 10-bit 20-channel ADC with internal reference and temperature sensor, dual DAC channels, and support for LIN-bus UARTs - all critical for deterministic real-time embedded control in harsh environments.
Technical Context
The R5F104LGGFA#30 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), enabling dynamic power/performance scaling. Its memory subsystem includes 512 KB code flash (1 KB blocks), 8 KB data flash with background operation (BGO) and 1M rewrite cycles, and 48 KB SRAM - optimized for firmware updates and data logging without halting execution.
Peripheral integration centers on event-driven efficiency: the Event Link Controller (ELC) supports 26 configurable event sources linked to peripherals (e.g., ADC trigger → DMA transfer), while the Data Transfer Controller (DTC) enables chain transfers across UART, SPI, and timer interrupts - reducing CPU load in sensor fusion and motor control loops.

The R5F104LGGFA#30 is rated for industrial operation from −40°C to +105°C (G-grade), validated for continuous use in sealed enclosures, outdoor equipment, and high-ambient-temperature factory environments. This exceeds standard A-grade (−40°C to +85°C) variants and ensures reliable RTC and LVD functionality across the full range.
Does the R5F104LGGFA#30 support hardware debugging during development?
Yes, the R5F104LGGFA#30 includes full on-chip debug functionality via the dedicated TOOL0/TOOLRxD/TOOLTxD pins (P40, P50, P51), compatible with Renesas E2 emulator and CS+ IDE. Debug operations - including breakpoint setting, register inspection, and flash programming - operate without requiring external debug probes beyond the standard JTAG/SWD interface.
How many analog-to-digital converter (ADC) channels does the R5F104LGGFA#30 provide?
The R5F104LGGFA#30 integrates a 10-bit successive-approximation ADC with up to 20 analog input channels (ANI0–ANI19), plus dedicated AVREFP/AVREFM reference pins and an on-chip temperature sensor. All channels operate across the full 1.6–5.5 V supply range, and the internal 1.45 V reference enables ratiometric measurements without external precision references.
Can the R5F104LGGFA#30 execute code while rewriting data flash memory?
Yes, the R5F104LGGFA#30 supports Background Operation (BGO) for data flash, allowing the CPU to execute instructions from code flash while simultaneously erasing or programming data flash sectors. This enables seamless firmware updates and data logging without interrupting real-time tasks - critical for industrial controllers requiring zero-downtime field upgrades.
