UPD8259-5 - PROGRAMMABLE INTERRUPT CONTROLLER

Download the UPD8259-5 datasheet PDF. This datasheet also covers the UPD8259 variant, as both devices belong to the same programmable interrupt controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The NEC pPD8259-5 is a programmable interrupt controller directly compatible with the 8080A/8085A/pPD780(Z80™).

It can service eight levels of interrupts and contains on-chip logic to expand interrupt capabilities up to sixty-four levels with the addition of other pPD8259-5's.

NEe Microcomputers, Inc. ~EC f'PD8259 ",PD8259·5 PROGRAMMABLE INTERRUPT CONTROLLER DESCRIPTION The NEC pPD8259-5 is a programmable interrupt controller directly compatible with the 8080A/8085A/pPD780(Z80™). It can service eight levels of interrupts and contains on-chip logic to expand interrupt capabilities up to sixty-four levels with the addition of other pPD8259-5's. The user is offered a selection of priority algorithms to tailor the priority processing to meet his systems requirements. These algorithms can be dynamically modified during operation, expanding the versatility of the microprocessor system.
