Z8023016PSC

Specialized Overview

The Z8023016PSC is an Enhanced Serial Communication Controller (ESCC) manufactured by ZiLOG. It features dual full-duplex serial channels designed for high-performance data communication applications. The device supports processing speeds up to 5 Mbps and accommodates a crystal oscillator, baud rate generator, and digital phase-locked loop on each channel. It utilizes a DIP-40 package with an operating temperature range of 0°C to +70°C.

Specialized Feature Summary

• Dual full-duplex channels with integrated baud rate generators and digital phase-locked loops
• Supports multi-protocol formats including asynchronous, bisync, SDLC/HDLC, and HDLC loop modes
• Includes hardware error detection via CRC-16 or CRC-CCITT algorithms
• Features FIFO buffers consisting of 4 bytes for transmission and 8 bytes for reception

Specialized Applications

• Telecommunication systems requiring serial-to-parallel conversion
• Local Area Network (LAN) interface implementations
• Multiprotocol data communication peripherals for microprocessors

Specialized Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'PSC' corresponds to the required commercial temperature range and packaging format. Request official datasheets and RoHS compliance documentation prior to procurement to ensure alignment with project specifications.

Specialized Selection Notes

Select this component when dual-channel synchronous or asynchronous communication is required without external logic complexity. Compare against standard SCC models if higher throughput exceeding 5 Mbps is necessary. Ensure the system architecture supports the specific protocol requirements such as HDLC or Bisync supported by the ESCC core.

Specialized Part Context

This part belongs to the Z80230 family of Enhanced Serial Communication Controllers within the broader ZiLOG SCC portfolio. It serves as an evolution over standard SCCs like the Z85C30, offering improved software simplification and reduced CPU overhead through enhanced internal functions and larger buffer capacities.

Specialized Replacement Considerations

The Z8023016VSC is a confirmed pin-compatible alternative in a PLCC-44 package. Other family members include the Z85230 series; however, functional equivalence requires verification of specific timing and voltage parameters.
