FAQ
What is the maximum operating frequency of the UPD78F1003GA(R)-HAA-AX?
The UPD78F1003GA(R)-HAA-AX operates at a maximum system clock frequency of 20 MHz, achieved using an on-chip high-speed oscillator or external crystal up to 20 MHz. This allows instruction execution at 50 ns per cycle, supporting real-time control tasks such as motor commutation and sensor sampling with deterministic timing.
Does the UPD78F1003GA(R)-HAA-AX support in-system programming?
Yes, the UPD78F1003GA(R)-HAA-AX supports in-application programming (IAP) via its built-in ROM-resident bootloader. Firmware updates can be performed over UART or I²C without removing the device from the board, using user-defined command protocols and protected Flash sectors to prevent accidental overwrite of critical code.
What are the power supply requirements for the UPD78F1003GA(R)-HAA-AX analog subsystem?
The UPD78F1003GA(R)-HAA-AX requires separate analog power (EVDD) and ground (EVSS) connections, rated for 2.7 V to 5.5 V. These pins must be decoupled with 100 nF ceramic capacitors near the package, and AVREF may be tied to internal 2.5 V bandgap or an external precision reference to ensure ADC accuracy within ±2 LSB.
How many ADC input channels does the UPD78F1003GA(R)-HAA-AX provide?
The UPD78F1003GA(R)-HAA-AX integrates a 10-bit successive-approximation ADC with 16 selectable input channels. Channels map to dedicated pins (e.g., AN0–AN15) and support simultaneous sampling across multiple ports, with hardware averaging configurable for 2× to 16× oversampling to enhance effective resolution.
Is the UPD78F1003GA(R)-HAA-AX pin-compatible with other devices in the 78K0R/KC3-L family?
Yes, the UPD78F1003GA(R)-HAA-AX shares identical 48-pin LQFP pinout and electrical characteristics with other 48-pin members of the 78K0R/KC3-L family, including UPD78F1000, UPD78F1001, and UPD78F1002. This enables hardware reuse across firmware variants and simplifies design scalability within the same package footprint.
