Z8523010VEC00TR

Specialized Overview

The Z8523010VEC00TR is a dual-channel Serial Communication Controller (SCC) from the Z85230 family, manufactured by Zilog. It operates at a maximum clock frequency of 10 MHz and supports data transfer rates up to 5 Mbps. The device features two full-duplex channels, each capable of accommodating a crystal oscillator, baud rate generator, and digital phase-locked loop. It utilizes an 8-bit external data bus and is housed in a 44-pin PLCC package. The component supports multiple communication protocols including asynchronous, bisync, SDLC/HDLC, and various encoding modes such as NRZI, FM0, FM1, and Manchester.

Specialized Feature Summary

• Dual full-duplex serial communication channels with independent baud rate generation capabilities
• Support for multi-protocol formats including asynchronous, bisync, and SDLC/HDLC standards
• Integrated error detection using CRC-16 or CRC-CCITT algorithms
• On-chip FIFO buffers consisting of 4 bytes for transmission and 8 bytes for reception

Specialized Applications

• Network interface controllers requiring high-performance serial data handling
• Industrial control systems utilizing SDLC/HDLC protocol stacks
• Embedded communication modules supporting bisync and asynchronous transmission

Specialized Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and temperature range. Confirm RoHS compliance status as it varies across the product line. Check for end-of-life notifications or product change notices that may affect long-term availability. Ensure the supply chain source provides valid traceability for this specialized interface controller.

Specialized Selection Notes

Select this component when a dual-channel SCC with 10 MHz processing speed is required. Compare against the Z85C30 series if lower power consumption is prioritized over the enhanced software features of the Z85230 family. Verify that the 44-pin PLCC package fits the target PCB layout constraints. Ensure the application does not require the higher DMA capabilities found in the Z16C35 series.

Specialized Part Context

This part belongs to the Z85230 enhanced serial communication controller family, designed to reduce CPU overhead through improved packet handling. It serves as a successor to earlier Z80/Z85C30 architectures, offering larger FIFOs and simplified programming interfaces while maintaining compatibility with standard Z80 bus protocols.

Specialized Replacement Considerations

The Z8523010VSC is a non-RoHS compliant alternative within the same family. For lead-free requirements, verify current RoHS-compliant variants such as the Z8523010VSG. Cross-reference pinouts to ensure compatibility with existing board designs.
