Z8523016VSC00TR

Specialized Overview

The Z8523016VSC00TR is a dual-channel Serial Communication Controller (SCC) from the Z85230 family, manufactured by Zilog. It operates within a voltage range of 4.5V to 5.5V and supports processing speeds 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 a 44-pin PLCC surface-mount package with an operating temperature range of 0°C to +70°C.

Specialized Feature Summary

• Dual full-duplex serial communication channels
• Support for multi-protocol formats including async, monosync, bisync, SDLC/HDLC, and HDLC loop
• Integrated FIFO buffers consisting of 4-byte transmit and 8-byte receive depths
• Hardware error detection using CRC-16 or CRC-CCITT

Specialized Applications

• Network interface implementations requiring high-performance serial data handling
• Embedded systems utilizing asynchronous or synchronous communication protocols
• Industrial control applications needing reliable data transmission over serial links

Specialized Procurement Notes

Verify component authenticity through authorized distributors as this part may be discontinued. Confirm that the specific suffix matches the required package and temperature grade. Ensure compatibility with existing system voltage levels and clock configurations before procurement.

Specialized Selection Notes

Select this controller when dual-channel support and integrated protocol handling are required. Compare against the Z85C30 series for standard multiplexing needs or the Z16C30 series for higher speed requirements exceeding 5 Mbps. Evaluate FIFO depth requirements against application latency constraints.

Specialized Part Context

This component belongs to the Z85230 enhanced SCC family, designed to reduce CPU overhead through advanced packet handling. It serves as a successor to earlier Z80C30 models, offering improved performance and simplified software integration for complex networking tasks.

Specialized Replacement Considerations

Consider the Z8523016PSC for DIP packaging alternatives or the Z8523016VEC for ceramic packages. Verify pinout compatibility and thermal characteristics when substituting with other members of the Z85230 family.
