FAQ

What is the maximum operating frequency of the UPD78F1003GA(S)-HAA-AX?

The UPD78F1003GA(S)-HAA-AX operates at a maximum system clock frequency of 20 MHz. This is achieved using an on-chip oscillator or external crystal up to 20 MHz, with internal PLL disabled. At this speed, the 78K0R core executes instructions with typical 1–2 cycle latency, enabling deterministic timing for motor control loops and sensor sampling intervals.

Does the UPD78F1003GA(S)-HAA-AX support in-circuit debugging?

Yes, the UPD78F1003GA(S)-HAA-AX supports single-wire in-circuit debugging via its dedicated debug interface, compatible with Renesas QB-MINI2 and third-party SWD tools. The interface requires only one dedicated pin (BSW) and shares no resources with user I/O, allowing full debug capability without sacrificing GPIO count or requiring additional PCB routing.

What is the Flash memory endurance specification for the UPD78F1003GA(S)-HAA-AX?

The UPD78F1003GA(S)-HAA-AX specifies 100,000 write/erase cycles for its 128 KB on-chip Flash memory, validated under standard industrial conditions (25°C, VDD = 3.3 V). Each 128-byte page can be erased independently, supporting efficient firmware updates and parameter storage without full-chip erase overhead.

How many analog input channels does the built-in ADC support on the UPD78F1003GA(S)-HAA-AX?

The UPD78F1003GA(S)-HAA-AX integrates a 10-bit successive approximation ADC with 8 dedicated analog input channels (AN00–AN07), all multiplexed onto Port 0 pins. The ADC supports hardware-triggered scan mode, automatic channel sequencing, and sample-and-hold - enabling continuous sensor monitoring with minimal CPU intervention.

Is the UPD78F1003GA(S)-HAA-AX qualified for industrial temperature operation?

Yes, the UPD78F1003GA(S)-HAA-AX is rated for operation from −40°C to +85°C and classified under Renesas' "Standard" quality grade, explicitly approved for industrial applications including factory automation, motor drives, and sensor systems. Its electrical specifications - including ADC accuracy, Flash retention, and timing parameters - are guaranteed across this full temperature range.
