ST 486 DX ASIC CORE

Fully Static 3.3V 486 DX/DX2/DX4 ASIC CORE

PRELIMINARY DATA

■

Fully Static 486 compatible core able to

operate from D.C to 120MHz

Manufactured in a 0.35 micron five layer

metal HCMOS process

8K byte unified instruction and data cache

with write back capability

Parallel processing integral floating point unit,

with automatic power down mode

Low Power system management modes

Cell libraries for 2.2V and 3.3V supply with

5 V I/O interface capability

2 - input NAND delay of 0.160 ns (typ) with

fanout = 2.

Broad I/O functionality including LVCMOS,

LVTTL, GTL, PECL, and LVDS.

■

Fully independent power and ground configu-

rations for inputs, core and outputs.

Programmable I/O ring capability up to 1000

pads.

Output buffers capable of driving ISA, EISA,

PCI, MCA, and SCSI interface levels.

Active pull up and pull down devices.

Buskeeper I/O functions.

Oscillators for wide frequency spectrum.

Broad range of 400 SSI cells.

Design For Test includes LSSD macro library

option and IEEE 1149.1 JTAG Boundary

Scan architecture built in.

Cadence based design system with inter-

faces from multiple workstations.

Broad ceramic and plastic package range.

■

High drive I/O; capability of sinking up to 48

mA with slew rate control, current spike sup-

pression and impedance matching.

Generators to support SPRAM, DPRAM,

ROM and many other embedded functions.

■

Latchup trigger current > +/- 500 mA.

ESD protection > +/- 4000 volts.
