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
