It is available for USD $149 and USD $299 for 16 MHz and 20 MHz respectfully in quantities of 100. It also has built-in DRAM refresh controller as well. It also has four (x4) 16-bit programmable internal timers which its superset Intel's 82C54 PIT. This chipset has 20-level programmable interrupt controller a superset of Intel's 82C59 PIC. 82380 - High Performance 32-Bit DMA Controller with Integrated System Support Peripherals.82350DT EISA - announced in April 1991.It integrated DMA controller, an interrupt controller PIC, serial and parallel ports, and power-management logic for the processor. It was a chipset for the mobile 80386SL and 80486SL processors. 82340DX PC AT - announced in January 1990, it is the Topcat chipset licensed from VLSI.82340SX PC AT - announced in January 1990, it is the Topcat chipset licensed from VLSI.Includes: 8234 Local I/O Channel Support Chips, 82307 DMA Controller/Central Arbiter, 82308 Micro Channel Bus Controller, 82309 Address Bus Controller, 82706 VGA Graphics Controller, 82077 Floppy Disk Controller. 82311 MCA - announced in November 1988.

82350 EISA - announced in September 1988.Includes: 82306 Local Channel Support Chip, 82307 DMA Controller/Central Arbiter, 82308 Micro Channel Bus Controller, 82309 Address Bus Controller, 82706 VGA Graphics Controller. 82091AA EISA/ ISA - Advanced Integrated Peripheral (AIP), includes: floppy disk controller, 2× UARTs, parallel port, IDE controller, oscillator, etc.This chipset can be used with an 82335 High-integration Interface Device to provide support for the Intel 386SX. Both set are available USD $60 for 10 MHz version and USD $90 for 12 MHz version in quantities of 100. The 82231 covers this combination of chips: 8254 interrupt timer, 74LS612 memory mapper and dual 8237A DMA controller among with other components.

The 82230 covers this combination of chips: 82C284 clock, 82288 bus controller, and dual 8259A interrupt controllers among with other components. To integrate the functions needed on a mainboard into a smaller amount of ICs, Intel licensed the ZyMOS POACH chipset for its Intel 80286 and Intel 80386SX processors (the 82230/82231 High Integration AT-Compatible Chip Set). the 8259 Programmable Interrupt Controller.5.6 Southbridge 9xx and 3/4 Series chipsetsĪn earlier chipset support for Intel 8085 microprocessor can be found at MCS-85 family section.Įarly IBM XT-compatible mainboards did not have a chipset yet, but relied instead on a collection of discrete TTL chips by Intel:.5.2 Pentium M/Celeron M mobile chipsets.5.1 Pentium 4/Pentium D/Pentium EE chipsets.
