Product Code : SCL-EELE-12718
Indian Lab Suppliers supplies the 8155 Simple Programmable Interface (Product ID: 12718) as part of its electronics engineering lab equipment range. It studies the 8155, which combines static RAM, programmable I/O ports and a timer in one IC.
Quick Answer
Three groups of experiments are listed: memory operations in the 8155's on-chip RAM, configuring its ports as inputs, outputs or a mix, and the different modes of its timer. Address, data and control levels are set on SPDT switches and shown on LEDs. Supporting ICs are eight 74LS244 tri-state buffers, a 2716 EPROM, a 555 timer, a 74LS32 OR IC, a 74LS00 NAND IC and a 74LS173 4-bit D-type register. A 5 V, 1 A regulated supply is built in, and the board runs from 230 V ±10%, 50 Hz mains with fuse and jewel light. Operating instructions with theory, design procedure and report suggestions are supplied.
