UltraSPARC II

The UltraSPARC II, code-named "Blackbird", is a microprocessor implementation of the SPARC V9 instruction set architecture (ISA) developed by Sun Microsystems.

The UltraSPARC IIi "Sabre" featuring on-chip PCI controller was a low-cost version introduced in 1997 that operated at 270 to 360 MHz.

In 1998, a version code-named Sapphire-Red, was fabricated in a 0.25 μm process, enabling the microprocessor to operate at 333 to 480 MHz.

The UltraSPARC IIe "Hummingbird" was an embedded version introduced in 2000 that operated at 400 to 500 MHz, fabricated in a 0.18 μm process with aluminium interconnects.

Code-named "Phantom", it operated at 550 to 650 MHz and was fabricated in a 0.18 μm process with copper interconnect.

[2] The "Dual-Core UltraSPARC (2003)" was based upon the UltraSPARC II microarchitecture and featured: DDR-1 memory controller, JBUS interface, parity protected L1 cache, ECC-protected dual 512KB on-chip L2 cache, 1.2 GHz clock frequency, 80 million transistors, 206 mm2 die size, and dissipated 23 watts of power.
