Z8523L16VEG

Specialized Overview

The Z8523L16VEG is a CMOS Serial I/O Controller manufactured by Zilog, Inc. It features two independent serial channels and supports multiple communication protocols including asynchronous, synchronous byte, HDLC, SDLC, X.25, BISYNC, and extended synchronous modes. The device operates at a maximum clock frequency of 16 MHz and functions within a supply voltage range of 4.5 V to 5.5 V. It is housed in a 44-lead PLCC surface-mount package with an operating temperature range from -40°C to +85°C.

Specialized Feature Summary

• Dual-channel architecture supporting simultaneous serial data transmission and reception
• Integrated FIFO buffers for efficient data handling and reduced CPU intervention
• Support for complex protocol implementations including HDLC and X.25

Specialized Applications

• Industrial communication systems requiring robust serial interfaces
• Network controller applications utilizing SDLC or BISYNC protocols
• Embedded systems needing high-speed synchronous data transfer

Specialized Procurement Notes

Verify the specific suffix 'VEG' against official Zilog documentation to confirm environmental ratings and lead composition. Confirm current availability status as this component may be subject to discontinuation notices. Ensure compatibility with existing system voltage levels before procurement.

Specialized Selection Notes

Select this component when dual-channel serial control with hardware protocol support is required. Compare against the Z8523008CMB if lower clock speeds are sufficient. Verify that the PLCC-44 package fits the target PCB layout constraints. Check for alternative packages if surface-mount installation is not feasible.

Specialized Part Context

This part belongs to the Z8523 family of Serial I/O Controllers produced by Zilog. These devices were designed to offload serial communication tasks from the main processor. The Z8523 series provides dedicated hardware handling for various data link layer protocols, reducing software overhead in embedded environments.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Engineering evaluation of functional equivalents requires direct comparison of pinouts, electrical characteristics, and protocol support capabilities.
