ST486 Product details

PRODUCT OVERVIEW
The ST 486 DX core is based on the design of the SGS-THOMSON standard 486 DX4 product. The core is capable of operating at the “external” bus speed or at two or three times the bus speed up to a maximum of 120MHz. Since the design is fully static the core can operate at any frequency between D.C and 120MHz.

■ 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.
■ High drive I/O; capability of sinking up to 48 mA with slew rate control, current spike suppression and impedance matching.
■ Generators to support SPRAM, DPRAM, ROM and many other embedded functions.
■ Fully independent power and ground configurations 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 interfaces from multiple workstations.
■ Broad ceramic and plastic package range.
■ Latchup trigger current > +/- 500 mA. ESD protection > +/- 4000 volts.
