Z80A N-Channel Silicon Gate CPU

Z80A CPUs are very easy to implement plus all output signals are fully decoded and timed to control standard memory or peripheral circuits. The circuit is implemented using an N-channel, ion implanted, silicon gate MOS process.

The Z80 microcomputer component set includes all the circuits necessary to build high-performance microcomputer systems with virtually no other logic and a minimum number of low cost standard memory elements. The two 16-bit index registers allow tabular data manipulation and easy implementation of relocatable code. The Refresh register provides for automatic, totally transparent refresh of external dynamic memories. The I register is used in a powerful interrupt response mode to form the upper 8 bits of a pointer to an interrupt service address table, while the interrupting device supplies the lower 8 bits of the pointer. An indirect call is then made to this service address.

Features
