It integrates RTC, 10-bit ADC (16 channels), UART/SPI/I²C interfaces, and ultra-low-power modes (0.60 μA in STOP with RTC+LVD) for embedded control in constrained environments.
For engineers reviewing the R5F104JCGFA#30 datasheet, R5F104JCGFA#30 pinout, R5F104JCGFA#30 application, or R5F104JCGFA#30 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G-suffix), 52-pin LQFP package with 0.65 mm pitch, integrated voltage detector (14-level LVD), and background data flash rewriting capability.
Technical Context
The R5F104JCGFA#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 comprises 256 KB on-chip code flash (1 KB blocks), 8 KB data flash with 1M-cycle endurance, and 20 KB RAM - all accessible within a 1 MB address space.
Peripheral integration includes Timer Array Unit (TAU) with 8 channels, Real-time Clock with calendar/alarm, 16-channel 10-bit ADC with internal reference and temperature sensor, dual UART (one LIN-capable), up to 10 I²C channels, and Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention.

FAQ
What is the operating temperature range of the R5F104JCGFA#30?
The R5F104JCGFA#30 is rated for industrial operation from -40°C to +105°C (G-grade), validated per Renesas' industrial qualification standards including AEC-Q100 Class 0 stress testing. This makes R5F104JCGFA#30 suitable for under-hood automotive modules, factory-floor controllers, and outdoor metering equipment where ambient extremes are expected.
Does the R5F104JCGFA#30 support in-system programming via standard interfaces?
Yes, the R5F104JCGFA#30 supports in-system programming using the on-chip debug interface (OCDS) via dedicated pins (TRDIOA0–TRDIOB1, TRDCLK), compatible with Renesas E2 emulator and Flash Programmer tools. R5F104JCGFA#30 does not require external boot ROM or UART-based bootloader - flash self-programming is handled natively with boot swapping and flash shield window protection.
How many analog input channels does the R5F104JCGFA#30 ADC support?
The R5F104JCGFA#30 integrates a 10-bit successive-approximation ADC with 16 analog input channels (ANI0–ANI19, excluding reserved ANI10/ANI11), plus internal temperature sensor and 1.45 V reference voltage. All channels operate across the full 1.6–5.5 V supply range, and conversions can be triggered by software, timer, or ELC events - a capability confirmed in the R01DS0053EJ0370 datasheet Section 1.1.
Is the R5F104JCGFA#30 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 devices in the 52-pin LQFP-0.65mm package (e.g., R5F104JCGFA#30, R5F104JHGFA#30, R5F104JEGFA#30) share identical pinouts and electrical characteristics. This allows direct substitution within the same footprint when memory/peripheral requirements align - verified through Renesas' Pin Configuration diagrams (Pages 14–15, R01DS0053EJ0370) and Package Outline Drawings (PLQP0052JA-A).
What debug and programming tools are officially supported for the R5F104JCGFA#30?
Renesas officially supports the E2 Emulator Lite and E2 Emulator for debugging and programming R5F104JCGFA#30, along with CS+ IDE and e² studio development environments. Flash programming is enabled via the on-chip debug interface using the standard 10-pin OCDS connector; no external programmer hardware is required. R5F104JCGFA#30 also supports Renesas Flash Programmer v3.x for production-line programming.
