Z0803606PSC

Overview

The Z0803606PSC is a CMOS Counter/Timer and Parallel I/O Unit manufactured by Zilog. It integrates three independent 16-bit counters/timers and sixteen general-purpose parallel I/O lines within a single package. The device operates on a single 5V supply and supports clock frequencies up to 6 MHz. It is housed in a 40-pin Plastic Dual In-line Package (PDIP) designed for through-hole mounting. The component functions as a support product for microprocessor systems, providing essential timing and interface capabilities without requiring external logic components.

Feature Summary

• Integrates three independent 16-bit counter/timer channels
• Provides sixteen general-purpose parallel I/O lines
• Operates with a single 5V power supply
• Supports maximum clock frequency of 6 MHz

Applications

• Microprocessor system timing control
• Parallel interface expansion for embedded controllers
• General-purpose event counting applications

Procurement Notes

This component is identified as an End-of-Life (EOL) product by the manufacturer. Availability is restricted to existing stock or surplus markets. Verification of authenticity and physical condition is required when sourcing from non-authorized distributors due to the discontinued status.

Selection Notes

Select this part for designs requiring integrated timing and I/O functionality in a legacy Zilog ecosystem. Ensure the design accommodates the PDIP-40 footprint and 5V logic levels. Verify that the 6 MHz maximum operating speed meets the system clock requirements.

Part Context

The Z0803606PSC belongs to the Z08 series of input/output controller interface ICs. It complements Zilog's Z8 and Z80 microprocessor families by offloading timer and I/O management tasks. The 'PSC' suffix denotes the specific plastic DIP packaging variant within this product line.

Replacement Considerations

As an EOL component, direct replacements are limited. Evaluate modern microcontrollers with built-in timers and GPIOs for new designs. For board upgrades, verify pin compatibility with alternative CIO devices from the same manufacturer family.
