DESCRIPTION
Programmable Peripheral Interface
40 Pin Dil Package
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.
Product Attributes
- The D8255AC-2 is a 40-pin DIP (Dual Inline Package) chip manufactured by NEC. It is a programmable peripheral interface (PPI) chip that is used to control and interface with peripheral devices. It is an 8-bit chip with three 8-bit ports (A, B, and C) and two 4-bit ports (D and E). It also has an internal 8-bit latch, two 8-bit shift registers, and two 4-bit counters. The D8255AC-2 is used to interface with peripheral devices such as keyboards, printers, and disk drives. It can be used to control the data flow between the CPU and the peripheral device, as well as to control the timing of the data transfer. It can also be used to generate interrupts to the CPU when a peripheral device needs attention. The D8255AC-2 is a popular chip for embedded systems and is used in many industrial applications. It is also used in some consumer electronics, such as video game consoles. (For reference only)
- Description: The D8255AC-2 is a 40-pin DIP (dual in-line package) chip manufactured by NEC. It is an 8-bit programmable peripheral interface (PPI) designed for use with microprocessors. Features: – Supports 8-bit parallel data transfer – Supports 4-bit and 8-bit I/O port configurations – Supports 8-bit interrupt vectoring – Supports DMA transfers – Supports multiple interrupt sources – Supports programmable I/O ports – Supports programmable timer/counter Applications: The D8255AC-2 is commonly used in embedded systems, industrial automation, robotics, and other applications that require parallel data transfer and programmable I/O ports. (For reference only)
It consists of three 8-bit bidirectional I/O ports (24I/O lines) which can be configured as per the requirement.
Purchasers will receive their chip (‘s) correctly packed in anti static packaging.

PLEASE NOTE!
These parts came to us as part of a lot of surplus stock from a large Milspec type Co. and have been kept in storage for some time, we have therefore classified them as ‘new other’. They are however in pristine condition, stored with us still in their original packaging, the photographs are representative of their excellent condition, being of some of our actual stock, and, as with all our products they come with a full guarantee.
If you have similar items to this, or indeed any electronic components that are surplus to requirements please contact us with details.
