PC87410 PCI-IDE Interface Controller

Support Mode

(11 MB/s) timing proposal on en-

General Description

hanced IDE (IDE-2 or ATA-2) specifications

Two IDE-2 channel supported (each channel supports 2

devices)

The PCI-IDE Interface Controller is designed to interface the

IDE drive directly onto the PCI bus. It provides write posting

and read pre-fetches, allowing the CPU to run concurrently

with IDE cycles. It connects IDE drIves ‘‘gluelessly’’ into the

PCI bus and supports faster ATA devices using modes 1, 2

and 3 through PIO accesses. It supports dual IDE channels

for up to four drives, and works seamlessly with the National

Semiconductor’s SuperI/O^TMfamily of products.

Supports primary IDE or secondary IDE address

16-Byte FIFO provide 4-level Posted Write and Read

ahead buffers per channel for concurrent system

operation

Programmable command and recovery timing for reads

and writes per channel

A full suite of software drives included with device are fully

tested with DOS 5.0–6.x, Windows 3.x–4.x, Windows NT,

OS/2 2.x, Novell Netware 3.1x–4.x, and SCO UNIX 3.x.

Independent timings for command registers and data

registers

Slew rate controlled output directly interface with IDE

devices

Key Features

Supports either IRQ14/15 or INTA /B

Fully compatible with PCI specifications rev 2.0 (April,

1993)

Hardware and Software chip enable/disable capability

100 pin PQFP package, NO other glue logic needed

and 12 mA transceivers are built in

Programmable Base Address registers

Interfaces with the 32 bits PCI local bus to IDE drives

Support IDE PIO timing mode 0, 1, 2 of ANSI ATA

specifications
