Z8023010VSC

Specialized Overview

The Z8023010VSC is an Enhanced Serial Communication Controller (ESCC) manufactured by Zilog, Inc. It features dual full-duplex serial channels and supports processing speeds up to 5 Mbps. The device accommodates a crystal oscillator, baud rate generator, and digital phase-locked loop on each channel. It handles multi-protocol formats including asynchronous, monosync, bisync, SDLC/HDLC, and SDLC/HDLC loop modes. Encoding options include NRZI, FM0, FM1, and Manchester. Error detection utilizes CRC-16 or CRC-CCITT. The component includes a 4-byte transmit FIFO and an 8-byte receive FIFO. It is housed in a 44-pin PLCC 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
• Support for multiple protocols including async, bisync, and HDLC/SDLC
• Integrated error detection using CRC-16 or CRC-CCITT
• On-chip FIFO buffers to reduce CPU overhead

Specialized Applications

• Telecommunication systems requiring high-speed serial data transfer
• Local Area Network (LAN) implementations
• Embedded systems utilizing multiprotocol serial communication

Specialized Procurement Notes

Verify the specific ordering suffix against official Zilog documentation to confirm pinout compatibility and environmental ratings. Ensure the selected variant matches the required operating temperature range and package type for the target application design.

Specialized Selection Notes

Select this component when dual-channel synchronous or asynchronous communication is required without external logic. Compare against standard SCCs if higher throughput or advanced protocol support is needed. Verify voltage levels and interface requirements against the host microprocessor system.

Specialized Part Context

This part belongs to the Z80230 ESCC family within the broader ZiLOG Serial Communication Controller lineup. It serves as an enhanced version offering improved performance and reduced external logic compared to earlier SCC generations like the Z85C30.

Specialized Replacement Considerations

The Z8523010VSC is a non-multiplex equivalent within the same family. Other compatible variants include Z8023016VSC for higher speed requirements.
