• Integrates hardware FIFO buffers for efficient data handling and status management.
• Capable of supporting modem control I/O lines usable as general-purpose I/O.

Specialized Applications

• Serial communication systems requiring robust protocol support.
• Network controllers in embedded processing environments.
• TDMA-based data link control applications.

Specialized Procurement Notes

This component is officially discontinued and listed as End-of-Life (EOL). Availability is restricted, and it may not be sold in all regions. Verification of stock through authorized distributors or secondary market sources is required before procurement planning. Designers should consider obsolescence risks and long-term supply constraints when integrating this part into new or existing systems.

Specialized Selection Notes

Select the Z8523L10VEG for applications requiring a 10 MHz serial controller with extended industrial temperature ratings. Ensure compatibility with 3.3 V logic levels and PLCC-44 footprint constraints. Verify that the specific L suffix variant meets the required environmental specifications compared to other members of the Z8523 family.

Specialized Part Context

The Z8523L10VEG belongs to the Z85230/Z85C30 family of serial communication controllers produced by Zilog. These devices are engineered to replace older standards like Intel 8274, offering enhanced functionality with reduced external logic requirements. The family supports various framing formats and encoding methods suitable for diverse networking and telemetry applications.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, alternative components must be identified based on functional equivalence and interface compatibility rather than direct cross-reference lists.
