Product details
Overview
R5F104LJGFP#30 from Renesas is a 64-pin LFQFP (10 × 10 mm, 0.5 mm pitch), industrial-grade RL78/G14 16-bit MCU with 192 KB flash, 8 KB data flash, 20 KB RAM, 1.6–5.5 V operation, and -40 to +105°C ambient range - deployed in motor control, sensor hubs, and battery-powered industrial nodes requiring ultra-low power (66 μA/MHz active, 0.60 μA RTC+LVD).
For engineers reviewing the R5F104LJGFP#30 datasheet, R5F104LJGFP#30 pinout, R5F104LJGFP#30 application, or R5F104LJGFP#30 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, integrated RTC with calendar/alarm, 10-bit 20-channel ADC, dual UART/LIN support, and hardware DTC/ELC for deterministic peripheral coordination without CPU load.
Technical Context
The R5F104LJGFP#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 memory subsystem integrates 192 KB code flash (1 KB blocks), 8 KB data flash with background operation (BGO), and 20 KB SRAM - all accessible within a unified 1 MB address space.
Peripherals are orchestrated via Event Link Controller (ELC) supporting up to 26 event sources and Data Transfer Controller (DTC) with chain transfer, enabling autonomous data movement between ADC, UART, and memory. Clocking uses a high-accuracy ±1.0% on-chip oscillator (selectable 1–64 MHz) plus external crystal support (X1/X2, XT1/XT2).

FAQ
What is the maximum operating frequency and core performance of the R5F104LJGFP#30?
The R5F104LJGFP#30 operates at up to 32 MHz with its RL78 CPU core, delivering 44 DMIPS of processing performance. Its high-accuracy on-chip oscillator supports frequencies from 1 MHz to 64 MHz with ±1.0% tolerance across -20 to +85°C, and the core's 3-stage pipeline enables minimum instruction execution times ranging from 0.03125 µs (high-speed mode) to 30.5 µs (ultra-low-speed mode). This flexibility allows dynamic clock scaling to match real-time requirements and power budgets in the R5F104LJGFP#30 design.
Does the R5F104LJGFP#30 support hardware-accelerated data transfers without CPU intervention?
Yes, the R5F104LJGFP#30 integrates a Data Transfer Controller (DTC) that supports normal, repeat, and block transfer modes triggered by 32 interrupt sources - including ADC end-of-conversion, UART receive complete, and timer overflow. The DTC's chain transfer function allows sequential memory-to-peripheral operations, such as streaming ADC results into a circular buffer while the CPU remains in low-power STOP mode. This capability is fully implemented in the R5F104LJGFP#30 silicon and documented in the RL78/G14 hardware manual.
What are the memory configuration details - specifically flash, data flash, and RAM - for the R5F104LJGFP#30?
The R5F104LJGFP#30 contains 192 KB of code flash memory organized in 1 KB erasable blocks, 8 KB of data flash memory rated for 1,000,000 write/erase cycles with background operation (BGO), and 20 KB of on-chip SRAM. The flash library reserves RAM starting at address F9F00H for self-programming operations. All memory regions reside within a unified 1 MB address space, and the data flash supports rewrites across the full VDD range of 1.8–5.5 V - confirmed in the R5F104LJGFP#30 datasheet revision 3.70.
How many analog input channels and what ADC resolution does the R5F104LJGFP#30 provide?
The R5F104LJGFP#30 features a 10-bit successive-approximation ADC with 20 configurable analog input channels (ANI0–ANI19), supporting single-ended and differential measurements. It includes an internal 1.45 V reference voltage and an integrated temperature sensor, both accessible via dedicated ANI pins. The ADC operates across the full supply range of 1.6–5.5 V and supports scan mode, hardware trigger (via ELC), and result buffering - all verified in the R5F104LJGFP#30 device specification.
Is the R5F104LJGFP#30 pin-compatible with other RL78/G14 variants in the same package?
The R5F104LJGFP#30 shares identical pinout, electrical characteristics, and package dimensions (64-pin LFQFP, 0.5 mm pitch) with all other RL78/G14 devices in the same FP package variant - including R5F104LKAFB#30, R5F104LLAFB#30, and R5F104LCAFB#30. Pin compatibility is guaranteed per Renesas' RL78/G14 ordering information guide (R01DS0053EJ0370), enabling drop-in replacement for memory or feature upgrades without PCB redesign. This applies specifically to the R5F104LJGFP#30 and its FP-package siblings.
