8259A General Description
The Intel 8259A Programmable Interrupt Controller handles up to eight vectored priority interrupts for the CPU It is cascadable for up to 64 vectored priority interrupts without additional circuitry It is packaged in a 28-pin DIP uses NMOS technology and requires a single +5V supply Circuitry is static requiring no clock input
The 8259A is designed to minimize the software and real time overhead in handling multi-level priority inter-rupts It has several modes permitting optimization for a variety of system requirements
The 8259A is fully upward compatible with the Intel 8259 Software originally written for the 8259 will operate the 8259A in all 8259 equivalent modes (MCS-8085 Non-Buffered Edge Triggered)
