Z84C2008VEC

Specialized Overview

The Z84C2008VEC is a CMOS Counter/Timer Circuit (CTC) belonging to the Z80 family, manufactured by Zilog. It operates on a single 5V supply and supports clock frequencies up to 8 MHz. The component is housed in a 44-lead Plastic Leaded Chip Carrier (PLCC) package designed for surface-mount installation. This integrated circuit functions as an I/O controller interface, providing three independent timer channels with programmable modes and interrupt capabilities for embedded systems.

Specialized Feature Summary

• Integrates three independent 16-bit counter/timer channels within a single CMOS package
• Supports multiple operating modes including square wave generation, rate generation, and one-shot pulse output
• Provides flexible interrupt logic with individual channel status flags and global interrupt control

Specialized Applications

• Real-time clock generation and time-base management in embedded controllers
• Serial baud rate generation for UART communication interfaces
• Programmable delay and timing control in industrial automation systems

Specialized Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance requirements against specific project standards, as historical production data indicates non-compliance with current environmental directives. Validate package integrity and pin alignment prior to PCB assembly to ensure reliable surface-mount soldering.

Specialized Selection Notes

Select this component when designing systems requiring multiple independent hardware timers without external logic gates. Ensure the design accommodates the 44-PLCC footprint and surface-mount reflow profile. Verify that the 5V logic levels match the target system's voltage domain and that the 8 MHz maximum frequency meets the required timing resolution.

Specialized Part Context

This part is a member of the Z84C20 series, which serves as the CMOS successor to the earlier NMOS Z84C20 CTC. It maintains binary compatibility with the Z80 peripheral ecosystem while offering lower power consumption and higher speed operation. The Z84C2008VEC specifically denotes the 8 MHz variant in the PLCC package format.

Specialized Replacement Considerations

The Z84C2008PEC is a pin-compatible alternative available in a 44-pin PDIP package for through-hole applications. Designers requiring lead-free compliance should evaluate newer Zilog peripherals, as this component may not meet modern environmental regulations.
