Motorola will produce a “super chip.”

Striking back in the microprocessor wars, Motorola said it will begin producing in March a chip that packs 300,000 transistors on a fingernail-sized sliver of silicon. Motorola’s announcement of its MC68030 chip comes the week after a buzz of publicity over Intel Corp.’s rival 32-bit microprocessor, the 80386, which was introduced last year. Motorola’s biggest market is engineering work stations, while the Intel chip is designed to run programs for IBM and IBM-compatible personal computers.
