Overview
R5F104LFGFA#30 from Renesas is a 64-pin LFQFP-packaged RL78/G14 16-bit microcontroller with 512 KB flash, 48 KB RAM, and 8 KB data flash, operating from 1.6 V to 5.5 V at up to 32 MHz (44 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.60 μA RTC+LVD), integrated 10-bit ADC (20 ch), RTC, and UART/I²C/CSI interfaces - deployed in industrial motor control and sensor-hub applications.
For engineers reviewing the R5F104LFGFA#30 datasheet, R5F104LFGFA#30 pinout, R5F104LFGFA#30 application, or R5F104LFGFA#30 equivalent, key selection criteria include its -40°C to +105°C industrial-grade temperature range (G-suffix), 0.5 mm pitch LFQFP-64 package, on-chip debug support, and BGO-capable data flash rewrite capability for firmware-over-the-air updates.
Technical Context
The R5F104LFGFA#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), multiply/divide/accumulate instructions, and 1 MB address space. It integrates a high-accuracy ±1.0% on-chip oscillator (1–64 MHz selectable) and dual-clock domain operation (main + subsystem).
Peripheral integration includes Timer Array Unit (TAU) with 8 channels, 12-bit interval timer, real-time clock with calendar/alarm, watchdog timer, and Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention - reducing latency and power in deterministic control loops.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F104LFGFA#30?
The R5F104LFGFA#30 operates at a maximum frequency of 32 MHz, delivering 44 DMIPS (Dhrystone MIPS) performance. This is achieved using the high-speed on-chip oscillator with ±1.0% accuracy across -40°C to +85°C, eliminating the need for an external crystal in many timing-critical industrial applications. The RL78 CPU core's 3-stage pipeline ensures deterministic execution for real-time control tasks.
Does the R5F104LFGFA#30 support background operation during data flash rewriting?
Yes, the R5F104LFGFA#30 supports Background Operation (BGO) for its 8 KB data flash memory. This allows the CPU to execute instructions from program memory while simultaneously rewriting data flash - essential for secure over-the-air firmware updates and non-disruptive parameter logging in industrial systems. The data flash endurance is rated at 1,000,000 write cycles (typical).
What is the operating temperature range and qualification grade for the R5F104LFGFA#30?
The R5F104LFGFA#30 is qualified for industrial applications with an operating ambient temperature range of -40°C to +105°C (G-grade). This is confirmed by the "G" suffix in the part number and aligns with Renesas' specification for extended-temperature industrial use cases such as motor drives, PLCs, and energy meters deployed in thermally demanding environments.
How many analog input channels does the integrated 10-bit ADC support on the R5F104LFGFA#30?
The R5F104LFGFA#30 integrates a 10-bit successive-approximation ADC with up to 20 analog input channels (ANI0–ANI19), including dedicated inputs for AVREFP/AVREFM, internal temperature sensor, and VCOUT0/VCOUT1 outputs. It supports internal 1.45 V reference voltage and operates across the full 1.6 V to 5.5 V supply range - enabling accurate sensor measurements without external references.
What package type and pin count does the R5F104LFGFA#30 use, and is it RoHS compliant?
The R5F104LFGFA#30 uses a 64-pin LFQFP package (10 × 10 mm body, 0.5 mm pitch), identified by the "FA" suffix and "#30" packaging code (LFQFP tray). It is RoHS compliant and halogen-free per Renesas standard specifications. The package features dual VDD/VSS pairs for improved noise immunity and supports standard lead-free reflow profiles (JEDEC J-STD-020).
