Z0853008VSC

Specialized Overview

The Z0853008VSC is a Serial Communication Controller (SCC) from the Zilog Z08530 series, designed for high-performance serial data transmission. It operates at a clock frequency of 8 MHz and supports a supply voltage range of 4.75 V to 5.25 V. The device is housed in a 44-lead PLCC package with surface-mount installation. It functions within an operating temperature range of 0°C to +70°C. Key specifications include support for multiple communication protocols such as HDLC, SDLC, and X.25, along with integrated FIFO buffers for efficient data handling.

Specialized Feature Summary

• Supports asynchronous and synchronous communication modes including byte-synchronous, bit-synchronous, and HDLC/SDLC protocols.
• Integrates dual-channel serial I/O capabilities with dedicated transmit and receive FIFO buffers.
• Provides programmable baud rate generation and flexible framing formats.

Specialized Applications

• Network interface controllers requiring protocol termination.
• Modem control systems utilizing modem status I/O lines.
• Industrial communication gateways supporting X.25 or BISYNC standards.

Specialized Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure proper ESD handling procedures are followed during storage and installation. Validate pin compatibility with existing PCB footprints before procurement.

Specialized Selection Notes

Select this component when designing systems requiring robust serial communication interfaces with hardware protocol support. Compare against the Z85230 series for similar functionality if different packaging or speed variants are needed. Ensure the 44-PLCC package fits the mechanical design constraints. Verify that the 8 MHz clock requirement aligns with the system's timing architecture.

Specialized Part Context

This part belongs to the Z08530 family of Serial Communication Controllers, which are CMOS-based peripherals designed to offload serial processing tasks from the main CPU. It complements other Zilog microprocessors like the Z80180 by providing dedicated serial I/O management. The Z08530 series is distinct from the Z85C30 CMOS version in terms of specific feature sets and manufacturing processes.

Specialized Replacement Considerations

The Z8523008PSC is a documented alternative within the same functional family, offering similar serial communication capabilities. Verify pinout compatibility and electrical characteristics before substitution. No other direct public substitutes are confirmed in available documentation.
