FAQ

What is the maximum operating frequency of the UPD78F1500AGK(S)-GAK-M1-AX?

The UPD78F1500AGK(S)-GAK-M1-AX supports a maximum system clock frequency of 20 MHz using either the internal high-speed oscillator (HOCO) or an external crystal source. This frequency enables deterministic execution of real-time control loops with sub-microsecond interrupt latency, and is fully supported across all operating voltage ranges (1.8 V to 5.5 V). The device maintains timing accuracy within specification under full temperature and voltage variation.

Does the UPD78F1500AGK(S)-GAK-M1-AX include a hardware real-time clock (RTC)?

Yes, the UPD78F1500AGK(S)-GAK-M1-AX integrates a dedicated real-time clock (RTC) module with calendar function (year/month/day/hour/minute/second), alarm capability, and independent 32.768 kHz sub-clock domain. It operates in STOP mode with minimal current draw and retains timekeeping during power-down states, making it suitable for timestamping and scheduled wake-up in battery-backed applications.

How many analog-to-digital converter (ADC) channels does the UPD78F1500AGK(S)-GAK-M1-AX support?

The UPD78F1500AGK(S)-GAK-M1-AX includes a 10-bit successive approximation ADC with 24 selectable input channels. These channels map to dedicated analog pins (e.g., AN00–AN23) and support hardware-triggered conversions, scan mode, and averaging across up to 16 samples per result-enabling high-precision sensor interfacing without software overhead.

Is the UPD78F1500AGK(S)-GAK-M1-AX pin-compatible with other members of the 78K0R/LF3 family?

No-while the UPD78F1500AGK(S)-GAK-M1-AX shares the LQFP-100 package with other 78K0R/LF3 devices like UPD78F1501A and UPD78F1502A, pin assignments differ across variants due to unique peripheral mappings (e.g., ADC channel allocation, serial interface routing). Engineers must consult the specific pin function table for UPD78F1500AGK(S)-GAK-M1-AX and verify I/O compatibility before board reuse.

What debug interface does the UPD78F1500AGK(S)-GAK-M1-AX support?

The UPD78F1500AGK(S)-GAK-M1-AX supports single-wire in-circuit debugging (SWI) via the dedicated SWI pin (P10/INTP0), enabling full breakpoint, register inspection, and flash programming using Renesas QB-MINI2 or compatible tools. This interface requires only one dedicated pin and operates independently of system clock settings, ensuring reliable debug access even during low-power or clock-failure conditions.
