Z84C3010AEG

Overview

The Z84C3010AEG is a CMOS Counter/Timer Circuit (CTC) from the Z84C30 series, manufactured by Zilog. Designed for Z80-based systems, it operates at a maximum clock frequency of 10 MHz. The device features three independent timer channels and supports multiple operating modes including binary and BCD counting. It is housed in a 44-pin VQFP surface-mount package with an extended industrial temperature range spanning from -40°C to +105°C. The component requires a single 5V power supply and includes humidity sensitivity indicators.

Feature Summary

• Three independent programmable timer/counters
• Maximum clock frequency of 10 MHz
• Extended industrial temperature range (-40°C to +105°C)
• Compatible with Z80 microprocessor architecture

Applications

• Z80-based embedded system timing control
• Industrial process monitoring intervals
• Real-time event counting applications

Procurement Notes

The Z84C3010AEG is listed as an End-of-Life (EOL) product by the manufacturer. Availability is restricted, and distributors may not stock this item in all regions. Verification of current supply status and potential obsolescence notifications is required before procurement planning.

Selection Notes

Select the Z84C3010AEG when a Z80-compatible CTC with 10 MHz operation and wide temperature tolerance is needed. Ensure the design accommodates the VQFP-44 package dimensions. Verify that the application does not require RoHS compliance if the specific revision lacks certification, as indicated in similar family listings.

Part Context

This component belongs to the Z84C30 series of CMOS CTCs. It shares functional similarities with other members like the Z84C3006AEG (6 MHz) and Z84C3008AEG (8 MHz), differing primarily in maximum clock speed and package variations within the same architectural family.

Replacement Considerations

Direct pin-to-pin replacements are limited due to the EOL status. Consider evaluating the Z84C3008AEG or Z84C3006AEG if lower clock speeds are acceptable. Cross-reference with modern Z80-compatible timer ICs if long-term supply stability is critical.
