Product details
Overview
R5F104LJGFA#30 from Renesas is a 64-pin LFQFP, 0.5 mm pitch, industrial-grade (−40°C to +105°C) RL78/G14 16-bit MCU with 192 KB flash, 8 KB data flash, 20 KB RAM, and integrated RTC, 10-bit ADC (20 channels), UART/LIN, I²C, SPI, and ultra-low-power operation (66 μA/MHz active, 0.60 μA in RTC+LVD mode). It targets battery-powered industrial sensors and motor control interfaces.
For engineers reviewing the R5F104LJGFA#30 datasheet, R5F104LJGFA#30 pinout, R5F104LJGFA#30 application, or R5F104LJGFA#30 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, 192 KB/8 KB/20 KB memory configuration, −40°C to +105°C industrial temperature rating, and support for LIN bus, background data flash rewriting, and hardware event linking via ELC.
Technical Context
The R5F104LJGFA#30 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz), and includes multiply/divide/accumulate instructions. Its on-chip peripherals are orchestrated via the Event Link Controller (ELC), enabling direct hardware-triggered peripheral activation without CPU intervention.
Power management integrates HALT, STOP, and SNOOZE modes, with independent voltage detector (LVD) interrupt/reset selection across 14 levels and a dedicated low-speed on-chip oscillator for watchdog timer operation. The Data Transfer Controller (DTC) supports block, repeat, and chain transfer modes activated by 19–26 configurable event sources.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F104LJGFA#30?
The R5F104LJGFA#30 operates up to 32 MHz with 44 DMIPS performance. At this frequency, active current consumption is 66 μA per MHz - resulting in approximately 2.1 mA total at 32 MHz with typical peripherals enabled. In STOP mode with only RTC and LVD active, it draws just 0.60 μA, making it ideal for long-life battery applications.
Does the R5F104LJGFA#30 support LIN 2.2 compliance out of the box?
Yes, the R5F104LJGFA#30 includes dedicated UART hardware with LIN bus support, including break detection, sync field handling, and checksum calculation. When configured per Renesas Application Note R01AN3223, it meets LIN 2.2 physical and data link layer requirements without external transceivers beyond standard ISO 17987-compliant drivers.
How many analog input channels does the R5F104LJGFA#30 support, and what is the ADC resolution?
The R5F104LJGFA#30 integrates a 10-bit successive approximation ADC with up to 20 analog input channels (ANI0–ANI19). It includes an internal 1.45 V reference voltage and on-die temperature sensor, enabling accurate measurements across its 1.6 V to 5.5 V supply range without external references.
Can the R5F104LJGFA#30 perform flash self-programming while executing application code?
Yes - the R5F104LJGFA#30 supports background operation (BGO) for data flash rewriting. Instructions can be fetched and executed from code flash memory while simultaneously erasing or programming data flash sectors, enabling robust over-the-air updates and runtime parameter storage without system interruption.
What is the purpose of the REGC pin on the R5F104LJGFA#30, and how must it be connected?
The REGC pin on the R5F104LJGFA#30 is the regulator bypass capacitor terminal for the internal LDO. It must be connected to VSS via a 0.47 µF to 1 µF ceramic capacitor placed as close as possible to the pin. Failure to do so risks unstable core voltage, erratic reset behavior, or failure to enter low-power modes reliably.
