UPD7105x compliant PC Peripheral Products

NEC Electronics is now offering RoHS-compliant replacement products compatible with the well-known UPD7105x PC peripheral devices.

UPD71051 <=> 8251 - Serial Control Unit

UPD71054 <=> 8254 - Programmable Timer Unit

UPD71055 <=> 8255 - Parallel Interface Unit

UPD71059 <=> 8259 - Interrupt Control Unit

Following the phase-out of the popular UPD7105x PC peripheral standard products, NEC Electronics can offer replacements based upon state-of-the-art, low-cost CMOS-N5 Gate Array ASIC technology. The replacement products will use RoHS-compliant, pin-compatible 44-pin QFP packages.

The underlying business model is very simple, just requiring the customer to verify the applicability of the replacement product (ie. a Gate Array ASIC) by testing an equivalent prototype chip within his system. After the successful in-system test, the customer confirms the applicability and releases production.

More details on the pin-out and package specifications can be found within the corresponding data sheets available on this web-site. NEC Electronics’ CMOS-N5 solutions efficiently support applications with annual quantities starting from as low as 1Kpcs.
