Why are so many customers usingthe Am486 in embedded designs?
• Time to MarketTake advantage of the many useful peripherals, standards,software packages, and tools that have already beendeveloped for the PC market– Chip Sets and core logic– PCI, Local Bus and ISA busses– VGA / NTSC / PAL graphics controllers– Ethernet, USB, “Super I/O” chips, Etc.
In most cases the driver software and protocol stacksare already written and available for the x86 architecture!
12AMD Embedded Processor Division, Am486DX Overview
Systems in Silicon
Why are so many customers usingthe Am486 in embedded designs?
• Price/Performance
– Unlike many embedded processors, the Am5x86(TM)
and Am486 have already amortized theirdevelopment costs over the tens of millions of unitsshipped to PC customers. 78 Million in ‘96 and 91Million shipped in ‘97
– The Am5x86(TM) (486DX5-133) is the fastest 486processor on the market. It offers 5th generationperformance at a 4th generation price and systemdesign
– Wide range of pin and software compatible optionsfrom the DX2-66 in the Low Cost package to theAm5x86

15AMD Embedded Processor Division, Am486DX Overview
Systems in Silicon
Why are so many customers usingthe Am486 in embedded designs?
• Software Compatibility– x86 is the Architecture with the widest support of
Operating Systems and Software ApplicationsPrograms.
• Broad, Established Set of Development Tools– The x86 Architecture has the widest range of highly
refined software development tools with great values /price.
16AMD Embedded Processor Division, Am486DX Overview
Systems in Silicon
Why are so many customers usingthe Am486 in embedded designs?
• Familiarity– Most engineers are already familiar with x86 hardware,
software, and design tools.
• Long Term Support and Integration– AMD’s Logic Products Division is committed to supporting
the embedded market with a long term and stable supply ofcompetitively priced microprocessors and microcontrollers.
17AMD Embedded Processor Division, Am486DX Overview
Systems in Silicon
Why are so many customers usingthe Am486 in embedded designs?
• Upgrade Roadmap– The x86 architecture has the broadest family of
software compatible processors in the world.– Desk top PC volume supports technology investment
that subsidizes embedded processors.• High speed cores available
– Frequencies now above 300 MHz
– Performance comparable to RISC• Shrinking geometries
– Lower and lower power
– Packaging advances
