Overview
R5F104PGAFA#30 from Renesas is a 48-pin LQFP-0.65 mm pitch, 96 KB flash, 12 KB RAM RL78/G14 16-bit MCU with ultra-low power consumption (66 μA/MHz), integrated 10-bit ADC (16 channels), UART/SPI/I²C interfaces, and real-time clock - deployed in battery-powered industrial sensor nodes and smart metering front-ends.
For engineers reviewing the R5F104PGAFA#30 datasheet, R5F104PGAFA#30 pinout, R5F104PGAFA#30 application, or R5F104PGAFA#30 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G), 1.6–5.5 V wide supply range, on-chip debug support, and hardware event link controller for deterministic peripheral triggering.
Technical Context
The R5F104PGAFA#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). It integrates an Event Link Controller (ELC) enabling direct hardware linkage of 19–26 event sources to peripherals without CPU intervention.

FAQ
What is the maximum operating frequency and corresponding current consumption of the R5F104PGAFA#30?
The R5F104PGAFA#30 operates up to 32 MHz using the high-speed on-chip oscillator. At this frequency, its typical active current is 66 μA per MHz, resulting in ~2.1 mA total at full speed with all peripherals enabled. In STOP mode with only RTC and LVD active, it draws just 0.60 μA - verified in the R01DS0053EJ0370 datasheet Section 1.1.
Does the R5F104PGAFA#30 support in-system programming and secure firmware updates?
Yes, the R5F104PGAFA#30 supports self-programming of both code and data flash memory with boot swapping and flash shield window protection. Its on-chip debug function enables ISP via the dedicated TOOLRxD/TOOLTxD pins, and security features prohibit unauthorized block erase or rewriting - all documented in Section 1.1 "Code Flash Memory" of the R01DS0053EJ0370 datasheet.
How many analog input channels and what ADC resolution does the R5F104PGAFA#30 provide?
The R5F104PGAFA#30 integrates a 10-bit successive-approximation ADC with 16 configurable analog input channels (ANI0–ANI15), plus two additional dedicated inputs (ANI16–ANI17) on P00/P01. It includes an internal 1.45 V reference and supports differential measurement modes - specified in Section 1.1 "A/D Converter" of the R01DS0053EJ0370 datasheet.
What serial communication interfaces are available on the R5F104PGAFA#30?
The R5F104PGAFA#30 provides 3 UART/LIN channels, 3–8 CSI (SPI-compatible) channels, and 4–10 I²C/simplified I²C channels - configurable via peripheral I/O redirection registers. Pin assignments for these interfaces are defined in Section 1.3.6 "48-pin products" of the R01DS0053EJ0370 datasheet, with P10–P17 and P60–P62 serving primary roles.
Is the R5F104PGAFA#30 qualified for industrial temperature operation?
Yes, the R5F104PGAFA#30 carries the 'G' suffix denoting industrial temperature grade, with guaranteed operation from -40°C to +105°C. This qualification is explicitly stated in Section 1.2 "Ordering Information" and Table 1-1 of the R01DS0053EJ0370 datasheet, confirming suitability for harsh thermal environments in factory automation and outdoor infrastructure.
