The Pentium® processor is fully compatible with the entire installed base of applications for DOS, Windows, OS/2, and UNIX, and all other software that runs on any earlier Intel 8086 family product. The Pentium processor's superscalar architecture can execute two instructions per clock cycle. Branch prediction and separate caches also increase performance. The pipelined floating-point unit delivers workstation level performance. Separate code and data caches reduce cache conflicts while remaining software transparent. The Pentium processor with voltage reduction technology has 3.3 million transistors. It is built on Intel's advanced low voltage BiCMOS silicon technology, and has full SL Enhanced power management features, including System Management Mode (SMM) and clock control. The additional SL Enhanced features, 2.9V core operation along with 3.3V I/O buffer operation, and the option of the TCP, which are not available in the desktop version of the Pentium processor, make the Pentium processor with voltage reduction technology ideal for enabling mobile Pentium processor designs. The Pentium processor may contain design defects or errors known as errata. Current characterized errata are available upon request.

PENTIUM® PROCESSOR WITH VOLTAGE REDUCTION TECHNOLOGY
INTRODUCTION

MICROPROCESSOR ARCHITECTURE OVERVIEW
Intel is manufacturing a reduced power version of the latest Pentium® processor, the Pentium processor with voltage reduction technology, targeting the mobile market. Voltage reduction technology allows the processor to "talk" to industry standard 3.3-volt components while its inner core, operating at 2.9 volts, consumes less power to promote a longer battery life. The Pentium processor with voltage reduction technology is offered in the Tape Carrier Package (TCP) and the Staggered Pin Grid Array (SPGA) package. It has all the advanced features of the 3.3V Pentium except for the differences listed in sections 3.1 and 7.1.1. The Pentium processor with voltage reduction technology has several features which allow highperformance notebooks to be designed with the Pentium processor, including the following: · TCP dimensions are ideal for small form-factor designs. · TCP has superior characteristics. thermal resistance
The Pentium processor with voltage reduction technology extends the Intel Pentium family of microprocessors. It is compatible with a host of other Intel products. The Pentium processor family consists of the Pentium processor with voltage reduction technology described in this document, the original mobile Pentium processor and the various desktop Pentium processors. "Pentium processor" will be used in this document to refer to the entire Pentium processor family in general. The mobile Pentium processor family architecture contains all of the features of the Intel486 CPU family, and provides significant enhancements and additions including the following: · · · · · · · · · · · · · · · · · Superscalar Architecture Dynamic Branch Prediction Pipelined Floating-Point Unit Improved Instruction Execution Time Separate 8K Code and 8K Data Caches Writeback MESI Protocol in the Data Cache 64-Bit Data Bus Bus Cycle Pipelining Address Parity Internal Parity Checking Execution Tracing Performance Monitoring IEEE 1149.1 Boundary Scan System Management Mode Virtual Mode Extensions Voltage Reduction Technology SL Power Management Features
· 2.9V core and 3.3V I/O buffer VCC inputs reduce power consumption significantly, while maintaining 3.3V compatibility externally. · The SL Enhanced feature set, which was initially implemented in the Intel486TM CPU. The architecture and internal features of the Pentium processor with voltage reduction technology are identical to the desktop version of the Pentium processor specifications provided in the Pentium® Processor Family Developer's Manual, Volume 1: ® Pentium Processors., except several features not used in mobile applications have been eliminated to streamline it for mobile applications. This document should be used in conjunction with the following related Pentium processor documents. · ·
