Z0853606VSG

Overview

The Z0853606VSG is a Counter/Timer Circuit (CTC) integrated circuit manufactured by Zilog. It operates at a frequency of 6 MHz and requires a supply voltage between 4.75 V and 5.25 V. The device consumes 200 mA of supply current. It is housed in a 44-PLCC package with J-leads, designed for surface mount installation. The component functions within an operating temperature range of 0°C to +70°C. This part belongs to the Z08536 series and is classified under programmable timers and oscillators.

Procurement Notes

This component is officially listed as obsolete or discontinued by the manufacturer. Verification of availability should focus on surplus distributors rather than primary channels. Check Product Change Notifications (PCN) for discontinuance dates, such as the June 2022 notification observed for similar variants. Ensure RoHS compliance status matches specific revision requirements before procurement.

Selection Notes

Select this part when a 6 MHz CTC function is required in a 44-pin surface mount format. Verify that the system power supply remains stable between 4.75 V and 5.25 V. Confirm that the ambient operating temperature will not exceed 70°C. Consider the 200 mA current draw for power budgeting. Alternative packages like PDIP exist for the same core function if through-hole mounting is preferred.

Part Context

The Z0853606VSG is part of the Zilog Z08536 family of peripheral controllers. It serves as a Counter/Timer Circuit (CTC), often used alongside Z80 microprocessors. The 'VSG' suffix typically denotes the 44-PLCC package variant. Other variants include Z0853606PSG in a 40-PDIP package. These components provide hardware timer and counter capabilities for embedded systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The Z0853606PSG offers identical functional specifications but utilizes a 40-PDIP through-hole package instead of the 44-PLCC surface mount form factor. Designers must evaluate pinout compatibility and mechanical constraints when considering package variations within the same series.
