82C55 IC Programmable Peripheral Interface IC
8255-82C55 Programmable Peripheral Interface IC
The 8255A is a general purpose programmable I/O device designed to transfer the data from I/O to interrupt I/O under certain conditions as required. It can be used with almost any microprocessor.
82C55 is a very old and obsolete 40 pin DIP IC. If you require in bulk please give us a call or e-mail us your requirement and we will try to procure it for you.

- The 82C55 is a popular interfacing component, that can interface any TTL-compatible I/O device to the microprocessor.
- It is used to interface to the keyboard and a parallel printer port in PCs (usually as part of an integrated chipset).
- Requires insertion of wait states if used with a microprocessor using higher that an 8 MHz clock.
- PPI has 24 pins for I/O that are programmable in groups of 12 pins and has three distinct modes of operation.
- In the PC, an 82C55 or its equivalent is decoded at I/O ports 60H-63H.
