New ZiLOG ZNEO 16-bit Single-Cycle CISC Targets High End Applications

September 27, 2006 - ZiLOG has introduced it's first 16-bit product as an extension of their popular Z8 8-bit product line. This new 16-bit core, called ZNEO (pronounced "Zee-No"), fills ZiLOG's product family portfolio and positions the company as a broad range microcontroller supplier.

Robin Abrams, ZiLOG's interim CEO, had this to say about the ZNEO: "ZNEO addresses the significant market demand for a full-featured, 16-bit solution providing up to 128KB Flash memory and more processing power, as well as a migration option with higher code density for our existing Z8 Encore! base. We are already working with several customers on security and high end motor control applications with ZNEO, providing a cost-competitive, single device System-on-Chip (SOC) option which, in motor control applications for example, can not only run the motor but control other functions of the product such as the display, keypad and other user interfaces, negating the need for additional MCUs and lowering overall bill of materials."
