The Z0843004PSC, also known as the Z80 CTC (Counter Timer Circuit), is a peripheral device manufactured by Zilog designed to provide timing and counting functions for Z80-based systems. It is commonly used to generate interrupts at precise intervals, control peripheral devices, and measure time intervals.

Applications

• Real-time clock implementations
• Peripheral device control
• Frequency generation
• Interrupt generation
• Event timing and counting
• Industrial control systems

Features

• Four independent timer/counter channels
• Programmable timer modes
• Programmable prescalers
• Interrupt generation on timer expiration
• Counter input for external event counting
• Single 5V power supply
• TTL compatible inputs and outputs
• Package: DIP (Dual In-line Package)

Benefits

• Provides versatile timing and counting functions for Z80 systems
• Enables precise control of peripheral devices
• Generates interrupts at precise intervals
• Allows for accurate time measurement
• Simplifies system design with a single power supply requirement
• Compatible with standard TTL logic levels

Additional Details

The Z0843004PSC/Z80CTC features four independent timer/counter channels, each of which can be programmed to operate in different modes. These modes include timer mode, counter mode, and event counting mode. Each channel has a programmable prescaler, allowing for a wide range of timing intervals. The device can generate interrupts on timer expiration, enabling the CPU to respond to events in real-time. It operates on a single 5V power supply and is compatible with standard TTL logic levels. The DIP package makes it easy to integrate into existing systems. The Z80 CTC provides a flexible and reliable solution for timing and counting applications in Z80-based systems.
