The Z0841004VSC is a Z80 PIO (Parallel Input/Output) device manufactured by Zilog. The Z80 PIO is a versatile peripheral component that provides parallel I/O capabilities for Z80-based systems. It enables the CPU to interface with external devices such as printers, keyboards, and other peripherals.

Applications

• Peripheral device interface for Z80 systems
• Industrial control systems
• Data acquisition systems
• Printer interface
• Keyboard interface
• General-purpose I/O

Features

• Two 8-bit parallel ports
• Programmable data direction (input or output) for each port
• Interrupt-driven I/O
• Handshake signals for reliable data transfer
• Single 5V power supply
• TTL compatible inputs and outputs
• Package: DIP (Dual In-line Package)

Benefits

• Provides flexible parallel I/O capabilities for Z80 systems
• Enables easy interfacing with a wide range of peripheral devices
• Supports interrupt-driven I/O for efficient data transfer
• Ensures reliable data transfer with handshake signals
• Simplifies system design with a single power supply requirement
• Compatible with standard TTL logic levels

Additional Details

The Z0841004VSC PIO provides two 8-bit parallel ports that can be independently programmed as either inputs or outputs. This flexibility allows for versatile interfacing with various peripheral devices. The interrupt-driven I/O capability enables efficient data transfer by allowing the CPU to perform other tasks while waiting for data to be ready. The handshake signals ensure reliable data transfer by coordinating the data flow between the PIO and the peripheral device. The device operates on a single 5V power supply and is compatible with standard TTL logic levels, simplifying system design. The DIP package allows for easy prototyping and experimentation.
