Z8523008VEC00TR

Specialized Overview

The Z8523008VEC00TR is a Serial Communication Controller (SCC) from the Z85230 family, manufactured by Zilog. It features dual full-duplex channels and supports processing speeds up to 5 Mbps. The device operates on a single 4.5V to 5.5V supply voltage and utilizes a 44-PLCC surface-mount package. It provides multi-protocol support including async, monosync, bisync, SDLC/HDLC, and SDLC/HDLC loop formats. Encoding modes include NRZI, FM0, FM1, and Manchester. Error detection is handled via CRC-16 or CRC-CCITT algorithms. The component includes a 4-byte transmit FIFO and an 8-byte receive FIFO for each channel.

Specialized Feature Summary

• Dual full-duplex serial communication channels
• Multi-protocol format support for various networking standards
• Integrated FIFO buffers for data handling
• Hardware error detection capabilities

Specialized Applications

• Networking applications requiring integrated serial controllers
• Systems utilizing asynchronous or synchronous data transmission
• Embedded devices needing high-performance serial I/O

Specialized Procurement Notes

Verify the exact ordering suffix against manufacturer documentation to confirm package type and temperature range specifications. Confirm RoHS compliance status as indicated in official datasheets. Check current availability and obsolescence notices directly with authorized distributors or the manufacturer before finalizing procurement plans.

Specialized Selection Notes

Select this component when dual-channel serial communication is required within the Z85230 family architecture. Ensure the system design accommodates the 44-PLCC package dimensions and the specified voltage supply range. Verify that the supported baud rates and protocol formats align with the specific interface requirements of the target application.

Specialized Part Context

This part belongs to the Z85230 enhanced SCC family, designed to reduce CPU overhead and external logic requirements. It shares core functionality with other variants like the Z8523008VEC but differs in packaging and specific suffix designations. The family focuses on simplifying software implementation through hardware-assisted packet handling and cycle access recovery.

Specialized Replacement Considerations

Consider the Z8523008VEC as a direct alternative if tube packaging is acceptable instead of tape and reel. Other family members such as the Z8523016VEC offer higher speed capabilities but require verification of pin compatibility and software configuration differences.
