AMD AM29000-16KC/W

The Am29000 and the low-cost Am29005 Streamlined Instruction microprocessors are high-performance, general-purpose, 32-bit microprocessors implemented in CMOS technology. They support a variety of applications by virtue of a flexible architecture and rapid execution of simple instructions that are common to a wide range of tasks.

Both processors efficiently perform operations common to all systems, while deferring most decisions on system policies to the system architect. They are well-suited for application in high-performance workstations, general-purpose super-minicomputers, high-performance real-time controllers, laser printer controllers, network protocol converters, and many other applications where high performance, flexibility, and the ability to program using standard software tools is important.

The Am29000 and Am29005 microprocessor instruction sets have been influenced by the results of high-level language, optimizing compiler research. They are appropriate for a variety of languages because they efficiently execute operations that are common to all languages. Consequently, the Am29000 and Am29005 microprocessors are an ideal target for high-level languages such as C, FORTRAN, Pascal, Ada, and COBOL.

The Am29000 and Am29005 microprocessors are available in a 168-lead Plastic Quad Flat Pack (PQFP) package. The package has 141 signal pins and 27 power and ground pins. The Am29000 microprocessor is also available in a 169-lead Pin Grid Array (PGA) package. The PGA has 141 signal pins, 27 power and ground pins, and 1 alignment pin.
