GENERAL DESCRIPTION

Based on a microcoded execution unit and an advanced CMOS

manufacturing technology, the Z80180, Z8S180, Z8L180 (Z8X180) is an

8-bit MPU which provides the benefits of reduced system costs and low

power operation while offering higher performance and maintaining

compatibility with a large base of industry standard software written

around the ZiLOG Z8X CPU.

Higher performance is obtained by virtue of higher operating frequencies,

reduced instruction execution times, an enhanced instruction set, and an

UM005001-ZMP0400
