FAQ

What is the maximum operating frequency of the UPD703017AGC-XXX-8EU-A?

The UPD703017AGC-XXX-8EU-A operates at a maximum CPU clock frequency of 32 MHz. This is achieved using an external crystal or clock source connected to the CLK pin, with internal PLL circuitry generating the core clock. At this speed, the device achieves a minimum instruction execution time of 31.25 ns, supporting tight real-time control loops in industrial applications.

Does the UPD703017AGC-XXX-8EU-A support in-system programming?

Yes, the UPD703017AGC-XXX-8EU-A supports in-system programming via its built-in 4 KB boot ROM. This ROM contains a UART-based bootloader that allows firmware updates without external programming hardware. The device uses on-chip charge pump circuitry to perform flash erase and write operations, eliminating the need for external high-voltage supplies during field updates.

What package type is used for the UPD703017AGC-XXX-8EU-A?

The UPD703017AGC-XXX-8EU-A is packaged in a 100-pin LQFP (Low-Profile Quad Flat Package) with dimensions of 14 mm × 20 mm and a 0.65 mm lead pitch. This JEDEC-standard package is lead-free compliant and qualified for reflow soldering per J-STD-020. The "8EU" suffix explicitly denotes this LQFP variant.

How much on-chip memory does the UPD703017AGC-XXX-8EU-A include?
