Pentium® Processors with MMX™ Technology
Low power
Product Overview
The 166MHz and 266MHz Low-power Pentium® processors with MMX™ technology offer many advantages for embedded designers, including high performance, low power, and extended temperatures. The processor family is available in a new surface-mountable 352-ball HL-PBGA (high thermal, low profile, plastic ball grid array) package, in addition to a Socket 7 (296-pin PPGA) package.

Low Power
These processors offer the lowest power consumption in the Pentium processor family, as they are based on Intel's 0.25 micron manufacturing process. These processors provide simplified, lower cost thermal management solutions for embedded system designs. With core voltages of only 1.9V and I/O voltages of 2.5V, the maximum power dissipation at 266MHz is merely 7.6W.

Extended Temperatures
The Pentium processor in the HL-PBGA package is also available in extended temperature ranges from -40°C to +115°C. The 430TX PCIset is also available in extended temperature ranges from -40°C to +85°C ambient. When combined with the extended temperature Pentium processor, these are an optimized solution for Interactive Clients, Industrial, and Communications applications.

Embedded Packaging Options
The Low-power Embedded Pentium processor with MMX technology is available in two packaging options:

  • The new small surface mount 352-ball HL-PBGA.
  • The 296-lead PPGA (Socket 7) package.
The HL-PBGA package has a small 35x35mm footprint, and is also very thin at only 1.45mm high. This small form factor is the solution to high-performance, small form factor requirements.
