The Zilog Z84C3010PEC, also known as the Z80-CTC (Counter Timer Circuit), is a versatile peripheral device designed to provide timing and counting functions for Z80 microprocessor-based systems. It offers four independent timer/counter channels that can be programmed for various timing and counting applications.

Applications

• Real-Time Clocks: Used to implement real-time clocks for timekeeping purposes.
• Frequency Generation: Employed for generating specific frequencies for various applications.
• Pulse Width Modulation (PWM): Utilized for generating PWM signals for motor control and other applications.
• Event Counting: Used to count external events.
• Interrupt Generation: Can generate interrupts at programmable intervals.

Features

• Four Independent Channels: Provides four independent timer/counter channels.
• Programmable Modes: Each channel can be programmed for various modes, including timer, counter, and event counter modes.
• Programmable Prescaler: Each channel includes a programmable prescaler for adjusting the counting frequency.
• Interrupt Generation: Can generate interrupts upon reaching a specific count or at programmable intervals.
• TTL Compatible: Compatible with TTL logic levels.

Benefits

• Versatility: Provides versatile timing and counting functions for a wide range of applications.
• Flexibility: Programmable modes and prescalers provide flexibility to adapt to different application requirements.
