Z0853606VEC00TR

Overview

The Z0853606VEC00TR is a Counter/Timer and Parallel I/O Unit manufactured by Zilog. It belongs to the Z8536 series, designed as a general-purpose peripheral circuit for system design needs involving counter/timer functions and parallel I/O control. The device supports real-time situations and interrupt control applications. It operates within a standard voltage range of 4.75V to 5.25V and features a maximum clock frequency of 6MHz. The component is housed in a 44-lead Plastic Leaded Chip Carrier (PLCC) package with J-leads, suitable for surface-mount installation.

Procurement Notes

This component is identified as an obsolete product by the manufacturer. Availability is restricted, and it may no longer be in active production. Verification of current stock status from authorized distributors or surplus suppliers is required before procurement planning. Check for Product Change Notifications (PCN) regarding end-of-life status.

Selection Notes

Select this part when a dedicated Zilog CIO interface is required for Z80/Z8000 family compatibility. Ensure the design accommodates the 44-lead PLCC footprint and 6MHz timing constraints. Verify that the 5V logic levels match the system requirements. Consider pinout compatibility if replacing earlier revisions of the Z8536 series.

Part Context

The Z0853606VEC00TR is part of the Z8536 CIO (Central Input/Output) line from Zilog. This series complements the Z80 microprocessor family by providing essential I/O and timing peripherals. The 'VEC00TR' suffix typically denotes the specific tape-and-reel packaging variant of the 44-lead PLCC package.

Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided documentation. Due to the obsolete status, alternative solutions may require functional equivalents from other manufacturers or redesigning the I/O interface using modern programmable logic devices.
