The Z84C3006PEC with Timers & Support Products 6MHz CMOS CTC XT is a single-chip version of the popular Z80 processor designed by ZiLOG, operating at 6 MHz clock rate, built on modern CMOS technology. It features a complete set of internal peripherals including 2, 64-bit synchronous/asynchronous timers, a System Management Interrupt controller, and a 10-bit programmable clock, making it a suitable replacement for the original Z80 in many applications. It has 512 bytes of on-chip RAM and can be programmed with up to 32KB of external EPROM or Flash memory. The chip supports the Classic Z80 instruction set, providing maximum compatibility for existing software, as well as some new instructions for system management and higher performance. The chip does not require any external power supplies.
