Product details
Overview
R5F104LCGFP#30 from Renesas is a 64-pin LFQFP (0.5 mm pitch), 512 KB flash, 48 KB RAM RL78/G14 16-bit microcontroller 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 sensor interface modules requiring extended temperature operation.
For engineers reviewing the R5F104LCGFP#30 datasheet, R5F104LCGFP#30 pinout, R5F104LCGFP#30 application, or R5F104LCGFP#30 equivalent, key selection criteria include its -40°C to +105°C industrial grade rating (G suffix), integrated 10-bit 20-channel ADC, dual UART/LIN support, and hardware DTC/ELC for deterministic real-time peripheral coordination.
Technical Context
The R5F104LCGFP#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 12-bit interval timer, calendar-based RTC with alarm/correction, and watchdog timer with dedicated low-speed oscillator.
Peripheral subsystems include up to 12 × 16-bit timers (TAU, RJ, RD, RG), 4–10 channel I²C/Simplified I²C, 3–4 UART/LIN channels, 3–8 CSI channels, and an Event Link Controller enabling direct hardware-triggered peripheral chaining without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F104LLGFP#30 | Same 64-pin LFQFP package, identical 512 KB flash/48 KB RAM, but rated for -40°C to +85°C (D-grade) instead of +105°C (G-grade) | Targeted for consumer or lower-temperature industrial environments where extended thermal range is not required | Select when full industrial temperature range is unnecessary and cost optimization is prioritized |
| R5F104LGJFP#30 | 64-pin LQFP (0.65 mm pitch), 384 KB flash, 32 KB RAM, same G-grade (-40°C to +105°C), but lacks one UART and two I²C channels | Suitable for space-constrained designs where PCB layout favors larger-pitch LQFP and reduced peripheral count suffices | Choose when footprint compatibility with legacy 0.65 mm pitch layouts is mandatory and memory/peripheral headroom is acceptable |
Compared with R5F104LCGFP#30, R5F104LLGFP#30 trades extended temperature capability for cost, while R5F104LGJFP#30 offers identical thermal rating in a different package with reduced memory and interface count-making R5F104LCGFP#30 optimal for high-reliability, feature-rich industrial edge nodes demanding maximum integration and thermal resilience.

FAQ
What is the operating temperature range for the R5F104LCGFP#30?
The R5F104LCGFP#30 is rated for industrial operation from -40°C to +105°C, indicated by the 'G' suffix in the part number. This extended range supports deployment in harsh environments such as motor drives, factory automation controllers, and outdoor sensor nodes where ambient temperatures exceed standard commercial limits.
Does the R5F104LCGFP#30 support in-system programming and secure firmware updates?
Yes, the R5F104LCGFP#30 supports self-programming of both code and data flash memory with boot swapping and flash shield window protection. Its on-chip debug interface enables secure firmware updates without requiring external programmers, and block erase prohibition prevents unauthorized modification of protected memory regions.
How many UART/LIN interfaces does the R5F104LCGFP#30 include, and are they hardware-supported?
The R5F104LCGFP#30 includes four fully independent UART peripherals with native LIN bus support (LIN 2.2 compliant). Each UART has dedicated hardware registers, baud rate generators, and break detection-no software bit-banging required for LIN communication or asynchronous serial protocols.
Can the R5F104LCGFP#30 operate from a single 1.8 V supply, and what peripherals remain functional?
Yes, the R5F104LCGFP#30 operates from 1.6 V to 5.5 V, including 1.8 V. At 1.8 V, the RL78 core runs at reduced frequency (≤ 8 MHz), but all peripherals-including 10-bit ADC, RTC, 8-bit DAC, I²C, and UART-remain fully operational per datasheet specifications, enabling ultra-low-voltage battery applications.
What packaging and lead finish does the R5F104LCGFP#30 use, and is it RoHS-compliant?
The R5F104LCGFP#30 uses a 64-pin LFQFP package (10 × 10 mm, 0.5 mm pitch) with matte tin lead finish. It is RoHS-compliant and halogen-free per Renesas standard product specifications, meeting IPC/JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) requirements for surface-mount assembly.
