Zilog Z8L18020FSG, 8bit Z80 Microcontroller, Z80, 20MHz ROMLess, 80-Pin PQFP

The Z80 CPUs are fourth-generation enhanced microprocessors with exceptional computational power. They offer higher system throughput and more efficient memory utilization than comparable second- and third generation microprocessors. The speed offerings from 6 -20 MHz suit a wide range of applications which migrate software. The Z80 architecture incorporates dual register banks that enable fast context switching and interrupt handling.
