Product details
Overview
R5F104LCGFA#10 from Renesas is a 64-pin LQFP-packaged RL78/G14 16-bit MCU with 16 KB flash, 2.5 KB RAM, and industrial-grade −40°C to +105°C operation (G-grade). It delivers 44 DMIPS at 32 MHz, features ultra-low-power HALT/STOP/SNOOZE modes (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates 10-bit ADC (16 channels), UART/LIN, I²C, SPI, RTC, and on-chip voltage detector for embedded control in motor drives and sensor nodes.
For engineers reviewing the R5F104LCGFA#10 datasheet, R5F104LCGFA#10 pinout, R5F104LCGFA#10 application, or R5F104LCGFA#10 equivalent, key selection criteria include its G-grade temperature rating, 64-pin LQFP-0.65 mm pitch package, 16 KB flash/2.5 KB RAM configuration, integrated LIN-capable UARTs, and support for background data flash rewriting with 1M-cycle endurance.
Technical Context
The R5F104LCGFA#10 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 µs @ 32 MHz to 30.5 µs @ 32.768 kHz). It supports multiply/divide/accumulate instructions and a 1 MB address space across four register banks.
Its peripheral set includes Timer Array Unit (TAU) with up to 8 channels, 12-bit interval timer, calendar RTC with alarm/correction, watchdog timer, and Event Link Controller (ELC) enabling direct hardware-triggered peripheral chaining without CPU intervention-critical for deterministic real-time response in industrial automation.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F104LCGFA#10?
The R5F104LCGFA#10 operates at up to 32 MHz, delivering 44 DMIPS of processing performance. This enables deterministic execution of real-time control algorithms such as PID loops or sensor fusion within sub-100 µs intervals. Its RL78 CPU core supports configurable instruction timing, allowing trade-offs between speed and power consumption depending on the selected clock source and operating mode.
Does the R5F104LCGFA#10 support LIN communication, and which UART channels implement it?
Yes, the R5F104LCGFA#10 supports LIN 2.2 communication through its UART channels - specifically UART0, UART1, and UART2 - all of which include hardware support for LIN sync-break detection, checksum generation, and identifier filtering. This eliminates the need for external LIN transceivers in basic slave-node implementations and simplifies compliance with automotive body electronics standards.
What are the memory resources allocated to the R5F104LCGFA#10, and how is data flash endurance specified?
The R5F104LCGFA#10 integrates 16 KB of code flash memory and 4 KB of data flash memory, with 2.5 KB of on-chip RAM. Its data flash is rated for 1,000,000 write/erase cycles (typical) and supports background operation (BGO), allowing program execution from main flash while data flash is being rewritten - essential for reliable firmware updates and non-volatile parameter storage in field-deployed devices.
How does the R5F104LCGFA#10 achieve ultra-low-power operation, and what is its lowest active current draw?
The R5F104LCGFA#10 achieves ultra-low-power operation through multiple low-power modes: HALT (66 μA/MHz), STOP (0.60 μA with RTC + LVD active), and SNOOZE (selective peripheral wake-up). Its minimum active current is 66 μA per MHz at 32 MHz, translating to ~2.1 mA total at full speed. The 0.60 μA STOP mode enables multi-year battery life in always-on sensor applications without compromising timekeeping or voltage monitoring.
Is the R5F104LCGFA#10 qualified for automotive or industrial temperature ranges, and what grade does its part number indicate?
Yes, the R5F104LCGFA#10 is qualified for industrial applications with an operating ambient temperature range of −40°C to +105°C, indicated by the "G" in its part number (R5F104LCGFA#10). This G-grade qualification meets requirements for under-hood automotive modules, industrial motor drives, and harsh-environment sensor systems where extended thermal stability is mandatory.
