Z8018010PSG

The Z8018x series Microprocessor Unit based on a microcoded execution unit and an advanced CMOS manufacturing technology. The Z80180 is a 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 on-chip memory management unit (MMU) with the capability of addressing up to 1MB of memory. Reduced system costs are obtained by incorporating several key system functions on-chip with the CPU. These key functions include I/O devices such as DMA, UART and timer channels. Also included on-chip are several glue functions such as dynamic RAM refresh control, wait state generators, clock oscillator and interrupt controller.
