Stealey Lincroft

Silverthorne is the core name for Intel's first generation of Atom processors based on the Bonnell microarchitecture, replacing Stealey. Those ultra-low power chips were manufactured on Intel's 45 nm process and were specifically aimed for the Mobile Internet device (MID) market. Silverthorne-based processors are 32-bit x86 single core processors with TDP ranging from just 650 mW to 2.5 W. Silverthorne superseded by Lincroft in 2010.

Overview

All models are based on Bonnell manufactured on a 45 nm process and implement x86-32 with no 64-bit support. This processor is designed to work with the Poulsbo chipset in both low-power CMOS mode as well as standard GTL mode.

Common Features

• TDP: 650 mW - 2.5 W
• ISA: Everything up to SSSE3 (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3)
• Tech: All models have EIST
• Bus: 400-533 MT/s FSB
• Poulsbo Chipset
• 47,212,207 transistors
• 3.1 mm x 7.8 mm die size
• 24.18 mm² die area
