In May 2006, Intel announced that 80386 production would stop at the end of September 2007.[9] Although it had long been obsolete as a personal computer CPU, Intel and others had continued making the chip for embedded systems. Such systems using an 80386 or one of many derivatives are common in aerospace technology and electronic musical instruments, among others. Some mobile phones also used (later fully static CMOS variants of) the 80386 processor, such as BlackBerry 950[10] and Nokia 9000 Communicator.
