Z80C3008VSC00TR

Specialized Overview

The Z80C3008VSC00TR is a CMOS Serial I/O Controller manufactured by Zilog. It features two independent serial channels capable of data transfer rates up to 0.3125 MBps. The device supports multiple communication protocols including ASYNC, BIT, SYNC BYTE, SYNC HDLC, SYNC SDLC, X.25, BISYNC, and EXT SYNC. Data encoding methods include NRZ, NRZI-SPACE, BIPH-MARK (FM1), BIPH-SPACE (FM0), and BIPH-LEVEL (MANCHESTER). It operates with an 8-bit address bus and an 8-bit external data bus. The component is housed in a 44-pin Plastic Leaded Chip Carrier (PLCC) package.

Specialized Feature Summary

• Dual-channel serial interface architecture for simultaneous communication tasks
• Supports diverse synchronous and asynchronous protocol standards
• Integrated hardware encoding and decoding capabilities

Specialized Applications

• Industrial control systems requiring reliable serial data transmission
• Embedded computer systems needing multi-port serial connectivity
• Telecommunications equipment utilizing standard serial protocols

Specialized Procurement Notes

Verify the specific suffix VSC00TR against official Zilog documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with existing PCB footprints for the 44-PLCC form factor. Check for RoHS compliance status as older Zilog components may not meet current environmental regulations. Confirm availability through authorized distributors given potential end-of-life status for legacy parts.

Specialized Selection Notes

Select this component when dual-channel serial I/O is required within a Z80-based system architecture. Consider the 0.3125 MBps throughput limit for bandwidth requirements. Evaluate the PLCC package constraints against board space and thermal management needs. Compare against newer UART alternatives if higher speeds or different pinouts are necessary.

Specialized Part Context

This part belongs to the Z80C3000 series of Serial I/O Controllers. It is designed to complement Z80 microprocessors and controllers. The series provides dedicated hardware support for serial communications, reducing CPU overhead. Variants differ primarily in clock speed, package type, and temperature range specifications.

Specialized Replacement Considerations

Direct pin-to-pin replacements may be limited due to the specific legacy nature of the Z80C3000 series. Verify functional equivalence with other Zilog CTC or SIO devices. Cross-reference with generic UART controllers if software abstraction layers allow for protocol translation.
