Z0853606VEG00TR

Overview

The Z0853606VEG00TR is a programmable Counter/Timer Circuit (CTC) and Parallel I/O unit manufactured by Zilog. It operates at a maximum frequency of 6MHz and is housed in a 44-pin PLCC package. The device integrates Z-CIO and CIO functionalities, providing general-purpose peripheral capabilities for system design. It supports real-time situations and interrupt control, eliminating the need for traditional quartz crystals through its internal oscillator architecture.

Feature Summary

• Integrates counter/timer and parallel I/O functions into a single general-purpose peripheral circuit
• Supports real-time processing and interrupt control applications
• Eliminates external quartz crystal requirements via internal oscillator design

Applications

• Real-time system timing control
• Interrupt management circuits
• Parallel input/output interface units

Procurement Notes

Verify the complete part number including the suffix to ensure correct packaging and temperature range specifications. Confirm that the 44-PLCC package matches the target PCB footprint. Check for any specific voltage supply requirements associated with the VEG variant before integration into the final design.

Selection Notes

Select this component when a combined counter/timer and parallel I/O solution is required without external oscillators. Ensure the 6MHz operational limit meets the system clock requirements. Consider the PLCC-44 package constraints during layout planning. Verify compatibility with the host microcontroller's interrupt handling capabilities.

Part Context

This device belongs to the Z0853606 series of Z-CIO and CIO Counter/Timer and Parallel I/O units. It is designed as a general-purpose peripheral to simplify system design by consolidating timing and I/O functions. The series addresses common needs in embedded systems requiring precise timing and data port management.

Replacement Considerations
