FAQ
What is the maximum operating frequency of the R5F109ACJSP#H0?
The R5F109ACJSP#H0 supports a maximum operating frequency of 24 MHz. This is achieved using the on-chip high-speed oscillator (HOCO) or an external crystal/resonator. The device maintains full peripheral functionality-including ADC conversion, UART communication, and timer operations-at this frequency, with timing margins verified across the full 1.6 V to 5.5 V supply range and industrial temperature grade (−40°C to +85°C).
Does the R5F109ACJSP#H0 include on-chip debug capability?
Yes, the R5F109ACJSP#H0 integrates a full on-chip debug circuit compliant with Renesas E1/E20 debug standards. This allows real-time program execution control, memory and register inspection, and non-intrusive trace without requiring external emulators. Debug access uses the single-wire SWD interface via the RESET pin, eliminating dedicated debug pins and preserving I/O resources for application use.
What ADC features does the R5F109ACJSP#H0 support?
The R5F109ACJSP#H0 includes a 10-bit successive-approximation ADC with 12 input channels, ±1 LSB integral nonlinearity (INL), and hardware-triggered sampling via timer overflow or external event. It also integrates a programmable gain amplifier (PGA) with selectable gains (1× to 32×) on dedicated analog input pins, enabling direct connection to low-output sensors such as thermopiles or strain gauges without external amplification.
Is the R5F109ACJSP#H0 qualified for automotive applications?
No, the R5F109ACJSP#H0 is designated as a Standard-grade product per Renesas quality classification and is intended for industrial, consumer, and office equipment-not automotive safety-critical systems. It is not AEC-Q100 qualified, lacks automotive temperature range (−40°C to +125°C), and does not include automotive-specific features such as enhanced ESD immunity or fault injection test coverage required for ASIL-B/C compliance.
What package type and pin count does the R5F109ACJSP#H0 use?
The R5F109ACJSP#H0 uses a 30-pin SSOP (Shrink Small Outline Package) with 0.65 mm lead pitch and JEDEC MS-012AC mechanical outline. Its pin layout matches the RL78/F12 30-pin family, including dedicated VDD/VSS pairs, RESET, REGC, and I/O ports P0–P2 configured for analog/digital multiplexing. This package supports automated surface-mount assembly and meets IPC-7351B land pattern recommendations.
