The Z0842006PSC is a Z80 Peripheral Interface Adapter (PIO) from ZiLOG. It is a 40-pin DIP integrated circuit designed to provide a simple interface between the Z80 microprocessor and peripheral devices. The Z80PIO features two independent 8-bit bidirectional I/O ports, each with an associated control register. It also includes an interrupt control register, a maskable interrupt output, and a non-maskable interrupt output. The device is capable of operating in either the Mode 0 or Mode 1, and can be programmed to generate an interrupt request when either the input or output port is changed. The Z80PIO is typically used in applications such as data acquisition, industrial control, and communication systems. It can be used to control a variety of peripheral devices such as LEDs, switches, motors, and sensors. It is also used to interface with serial and parallel devices such as printers, modems, and displays. (For reference only)
