Although initial versions of National Semiconductor’s NS32532 microprocessor will be in 2 micron CMOS and clocked at 20MHz (CI No 653), the company says it intends that production parts will be in 1.25 micron CMOS and have a 30MHz clock; the part will initially be offered with the NS32381 arithmetic co-processor for applications that need one, but a higher-performance part will be announced later this year.
