SPEAr300, SPEAr310, SPEAr320, and SPEAr600 Embedded Microprocessors

STMicroelectronics launched the SPEAr300, SPEAr310, SPEAr320, and SPEAr600 embedded microprocessors. The four new SPEAr (Structured Processor Enhanced Architecture) microprocessors combine one or two advanced ARM9 processor cores with memory interfaces, and a large set of IP blocks. ST’s new SPEAr embedded microprocessors are in full production. The single-core models (SPEAr300/310/320) are priced below $7 for mass production quantities. The dual-core SPEAr600 sells below $9 for mass production quantities.
