XP8255 – Programmable Peripheral Interface (I/O Expander) – Xinluda

The Xinluda XP8255 is an 8255-compatible Programmable Peripheral Interface offering 24 programmable, TTL-compatible I/O pins in an LCC-44 package. Available for RFQ through Pacific Component Xchange.

The Xinluda XP8255 is a general-purpose Programmable Peripheral Interface (PPI) in the industry-standard 8255 family, used to expand parallel I/O for microprocessor and microcontroller systems. It provides 24 programmable I/O pins organized for flexible interfacing with peripherals such as keypads, displays, printers, and relay banks. Inputs and outputs are TTL-compatible, the device is fully compatible with the 8080/8085 microprocessor families, and it integrates eight Darlington-type drive outputs suited to printer and display loads, making it a practical drop-in style peripheral controller for embedded and industrial designs.

Supplied in a surface-mount LCC-44 (16.6 x 16.6 mm) package and rated for an industrial -40°C to +85°C operating range, the XP8255 operates from a single 4.5 V to 5.5 V supply, aligning it with classic 5 V logic systems. It is a cost-effective parallel-interface solution for designers maintaining or building 8255-architecture hardware.
