Additional Details:

The Z0840004PSC (Z80 CPU) operates at a clock speed of 4 MHz. It includes several internal registers, including general-purpose registers, an accumulator, and a flag register. The processor supports various addressing modes, including direct, indirect, and indexed addressing. It also features a built-in interrupt controller, which allows for prioritized interrupt handling. The Z80 is typically packaged in a 40-pin DIP (Dual In-line Package). It requires a single 5V power supply for operation. The Z80's instruction set is an enhanced version of the Intel 8080 instruction set, making it relatively easy to port software from the 8080 to the Z80. The processor has been widely emulated, and many development tools are available for creating Z80-based applications. Its legacy continues to influence modern embedded systems and computer architecture.
