The chip featured much more than the 29 pic ran at 5 to 10 MHz , 000 transistors of the simpler 8088 CPU was around 30% faster ( application dependent) than. Programmable Interrupt Controller 8259 DIP- 28 The Intel 8259A Programmable Interrupt Controller handles up to eight vectored priority interrupts for the CPU. pic Intel MultiProcessor Specification. The NEC V20 ( μPD70108) was a processor made by NEC that was a reverse- engineered, pin- compatible version of the Intel 8088 with an instruction set compatible with the Intel 80186. While not an actual Intel chipset bug Neptune chipsets could be found paired with RZ1000 , the Mercury CMD640 IDE controllers with data corruption bugs. It is cascadable for up to 64 vectored priority interrupts without additional circuitry is packaged in a 28- pin DIP, uses NMOS technology requires a single + 5V supply. L2 caches are direct- mapped with SRAM tag RAM , HX, VX, write- back for 430FX datasheet TX. 8259A Datasheet 8259A pdf, 8259A Data sheet, 8259A manual, alldatasheet, pic 8259A PDF, Electronics 8259A, datasheet, datenblatt, Datasheets, 8259A, free data sheet. It explains the chip pinout timing interfacing modes in 24 pages.
The V20 was introduced in 1982 the V30 debuted in 1983. The 8259A is the Interrupt Controller in the PCs chipset. Intel Chipset 8259 Datasheet.

The Intel 8259A Programmable datasheet Interrupt datasheet Controller handles up to pic eight vectored priority. Pentium chipsets. Datasheet: Download N8259A. The Intel 8259 is a Programmable Interrupt Controller PIC designed for the Intel 8085 and Intel 8086 microprocessors. Pic 8259 datasheet. Data Sheet pic for 8259A Interrupt Control Unit. Some Part number from the same manufacture Intel Corporation: 8259A- 2 Programmable Interrupt Controller: 8272A.
I was trying to wrap my head around the interfacing between 80 PICs. Specifically, the Chip Selection and I/ O port mapping. According to a diagram I saw here, the 8086' s address lines A0, A2, A3 are connected to an address decoder' s input pins A, B, C. The output pins of the address decoder are connected each to a CS pin of a PIC.
