FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F104FJAFP#30?
The R5F104FJAFP#30 operates up to 32 MHz with a high-speed on-chip oscillator (±1.0% accuracy). At this frequency, its HALT mode consumes 66 μA/MHz - totaling ~2.1 mA at 32 MHz - while STOP mode draws only 0.60 μA with RTC and LVD active. These values are measured at VDD = 1.8–5.5 V and TA = –40 to +85°C.
Does the R5F104FJAFP#30 support in-system programming and secure firmware updates?
Yes, the R5F104FJAFP#30 supports full in-system programming via on-chip debug interface and includes flash shield window, boot swapping, and block erase prohibition for secure firmware updates. The 96 KB code flash and 8 KB data flash allow dual-bank operation, enabling fail-safe updates without external memory.
How many UART/LIN interfaces does the R5F104FJAFP#30 provide, and are they hardware-accelerated?
The R5F104FJAFP#30 provides four UART channels, all supporting LIN 2.2 protocol in hardware - including automatic sync-break detection, checksum calculation, and header/response framing. UART2 (P13/P14) and UART3 (P15/P16) are fully independent and can operate concurrently with different baud rates and parity settings.
Can the R5F104FJAFP#30's ADC measure internal temperature and reference voltage simultaneously?
Yes, the R5F104FJAFP#30's 10-bit ADC supports simultaneous measurement of the internal temperature sensor and internal 1.45 V reference voltage (AVREFM/AVREFP). This enables real-time thermal compensation of analog measurements without external components - critical for precision sensor front-ends.
What packaging and lead finish does the R5F104FJAFP#30 use, and is it RoHS compliant?
The R5F104FJAFP#30 uses a 44-pin LQFP package (10 × 10 mm, 0.8 mm pitch) with matte tin lead finish (Sn), fully compliant with RoHS Directive 2011/65/EU and REACH SVHC regulations. The Renesas code PLQP0044GC-A confirms JEDEC-standard footprint and reflow profile compatibility.
