Z8523008VSC

Specialized Overview

The Z8523008VSC is an enhanced serial communication controller (ESCC) manufactured by ZiLOG. It features dual full-duplex 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 operates within a temperature range of 0°C to +70°C and utilizes a 44-pin PLCC package.

Specialized Feature Summary

• Dual full-duplex channels for simultaneous data transmission and reception
• Supports multi-protocol formats including asynchronous, bisync, SDLC, and HDLC
• Integrated on-chip baud rate generators and digital phase-locked loops

Specialized Applications

• Telecommunication systems requiring high-speed serial data transfer
• Local Area Network (LAN) implementations
• Multiprotocol data communication peripherals for microprocessors

Specialized Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix VSG or VSC matches the required package type and operating temperature range. Check for end-of-life status and availability of long-term supply agreements if applicable.

Specialized Selection Notes

Select this model when dual-channel ESCC functionality with 5 Mbps capability is required. Ensure the system design accommodates the 44-pin PLCC footprint. Verify that the 0°C to +70°C commercial temperature range meets environmental requirements compared to industrial variants.

Specialized Part Context

This component belongs to the Z85230 family of enhanced serial communication controllers. It shares architectural similarities with the standard Z85C30 series but offers improved software simplification and FIFO depths. It serves as a versatile peripheral for 8-bit and 16-bit microprocessor systems.

Specialized Replacement Considerations

The Z8523008VEC is a ceramic equivalent in the same family. For plastic packages, verify pin compatibility with other Z85230 variants. Cross-reference with Z80230 series for multiplexed bus interface options.
