FAQ

What is the maximum operating frequency of the UPD78F1513AGC-UEU-AX?

The UPD78F1513AGC-UEU-AX supports a maximum system clock frequency of 20 MHz. This can be achieved using either the internal high-speed oscillator (HOCO) or an external crystal/resonator. At 20 MHz, the CPU delivers 1.25 DMIPS per MHz, enabling deterministic execution of real-time control loops within strict timing budgets.

Does the UPD78F1513AGC-UEU-AX include a real-time clock (RTC) with calendar function?

Yes, the UPD78F1513AGC-UEU-AX integrates a hardware RTC with full calendar support (year/month/day/hour/minute/second) and alarm interrupt capability. It operates from a dedicated VBAT domain, allowing timekeeping during main power-off states, and is fully accessible via dedicated SFRs without CPU intervention.

What package type and pin count does the UPD78F1513AGC-UEU-AX use?

The UPD78F1513AGC-UEU-AX is supplied in a 100-pin LQFP package (14 mm × 14 mm, 0.5 mm pitch) with exposed thermal pad. This package matches the pinout of other 78K0R/LG3 devices such as UPD78F1515AGC-UEU-AX, enabling footprint reuse across variants with differing Flash sizes.

How many ADC channels does the UPD78F1513AGC-UEU-AX support, and what is its resolution?

The UPD78F1513AGC-UEU-AX features a 10-bit successive approximation ADC with 24 selectable input channels. It includes sample-and-hold circuitry, hardware trigger support from timers or external events, and configurable conversion sequences-enabling precise analog measurement in motor current sensing and sensor signal conditioning.

Is the UPD78F1513AGC-UEU-AX pin-compatible with other members of the 78K0R/LG3 family?

Yes, the UPD78F1513AGC-UEU-AX shares identical pin configuration and electrical characteristics with all 100-pin LQFP variants in the 78K0R/LG3 family, including UPD78F1515AGC-UEU-AX and R5F10PLGCLFB#30. This allows direct PCB reuse when scaling Flash size or removing RTC functionality without layout changes.
