The Z8536DS is a Zilog Counter/Timer and Parallel I/O Unit (CIO). It's designed to provide versatile timing, counting, and parallel I/O capabilities for microprocessor-based systems. The CIO integrates multiple counter/timer channels and parallel I/O ports into a single chip, simplifying system design and reducing component count.

Applications:

• Industrial Control Systems
• Peripheral Control
• Data Acquisition Systems
• Timing and Event Counting
• Motor Control
• Robotics

Features:

• Three independent 16-bit counter/timer channels
• Parallel I/O ports with programmable direction
• Interrupt handling capabilities
• Programmable operating modes for counters and timers
• Compatible with Z80 and other microprocessors
• Flexible interrupt structure
• Single 5V supply operation

Benefits:

• Versatile timing and counting capabilities enhance system performance.
• Parallel I/O ports provide flexible interfaces for external devices.
• Integration reduces component count and board space, lowering system cost.
• Programmable operating modes allow for customization to specific application requirements.
• Compatibility with Z80 and other microprocessors simplifies system integration.

Technical Specifications:

The Z8536DS operates from a single 5V power supply. Each of the three 16-bit counter/timer channels can be configured to operate in various modes, including event counting, interval timing, and pulse width measurement. The parallel I/O ports can be programmed as input or output ports. The device provides interrupt handling capabilities, allowing the microprocessor to respond to timer events or external signals. Detailed timing diagrams, programming information, and application notes are available in the Zilog Z8536 datasheet.
