FAQ

What is the maximum operating frequency of the UPD78F1010GK-GAK-AX?

The UPD78F1010GK-GAK-AX operates at a maximum CPU clock frequency of 20 MHz under rated supply voltage (2.7–5.5 V) and ambient temperature (−40°C to +85°C). Its internal PLL supports multiplication of external crystal or ceramic resonator inputs up to this limit, and instruction execution achieves 1.25 MIPS per MHz due to optimized 78K0R pipeline architecture.

Does the UPD78F1010GK-GAK-AX support in-circuit debugging?

Yes, the UPD78F1010GK-GAK-AX supports single-wire debug (SWD) via the dedicated debug interface, fully compatible with Renesas QB-78K0RKX3C in-circuit emulator. This enables real-time variable inspection, hardware breakpoints, and non-intrusive program flow tracing without requiring dedicated debug pins beyond the standard SWCLK/SWDIO signals.

How many analog input channels does the UPD78F1010GK-GAK-AX ADC support?

The UPD78F1010GK-GAK-AX integrates a 10-bit successive-approximation ADC with 16 selectable analog input channels (AN0–AN15), mapped across P40–P47 and P50–P57 port pins. Channel selection is software-configurable via the ADPC register, and conversions can be triggered by software, timer match events, or external signals.

What power supply domains does the UPD78F1010GK-GAK-AX use for analog circuitry?

The UPD78F1010GK-GAK-AX employs two dedicated analog power domains: EVDD0/EVDD1 (analog VDD) and EVSS0/EVSS1 (analog VSS), physically isolated from digital VDD/VSS. This separation minimizes digital switching noise coupling into the ADC and comparator, enabling <1 LSB integral nonlinearity and stable reference performance across temperature.

Is Flash memory programming supported on the UPD78F1010GK-GAK-AX during normal operation?

Yes, the UPD78F1010GK-GAK-AX supports in-application programming (IAP) of its 128 KB on-chip Flash memory. Using the built-in Flash control module and protected write sequences, firmware can erase and reprogram Flash blocks while the CPU executes from RAM or other Flash regions-enabling field firmware updates without external tools.
