Z8523010VSG

Specialized Overview

The Z8523010VSG is an Enhanced Serial Communications Controller (ESCC) manufactured by Zilog. It operates at a maximum frequency of 10 MHz and supports a supply voltage range of 4.5 V to 5.5 V with a typical operating current of 4 mA. The device features two serial channels and utilizes a PLCC-44 surface-mount package. It functions as a communication controller supporting asynchronous, synchronous byte, HDLC, SDLC, X.25, BISYNC, and extended synchronous protocols. The component includes integrated FIFO buffers for transmit and receive operations.

Specialized Feature Summary

• Supports multiple data communications protocols including SDLC, HDLC, and X.25
• Integrates 4-byte transmit and 8-byte receive FIFO buffers
• Provides vectored interrupt capabilities with daisy-chain support
• Includes programmable baud rate generator and digital phase-locked loop

Specialized Applications

• Network interface controllers requiring serial protocol handling
• Modem control systems utilizing modem status lines
• Embedded communication subsystems needing DMA or CPU-controlled data transfer

Specialized Procurement Notes

Verify the specific suffix designation against the manufacturer's official ordering guide to confirm voltage levels and temperature ranges. Confirm end-of-life status and availability through authorized distributors. Ensure compatibility with existing system bus timing requirements before integration into new designs.

Specialized Selection Notes

Select this component when a dedicated serial controller with hardware protocol offloading is required. Compare pinout compatibility with legacy SCC devices if replacing older architectures. Verify that the 44-pin PLCC package fits the target PCB layout constraints. Check if the 10 MHz speed meets the system clock synchronization needs.

Specialized Part Context

This part belongs to the Z85230 family of Enhanced Serial Communications Controllers. It shares architectural similarities with the Z80230 but differs in bus interface implementation. The Z85230 series provides enhanced FIFO capabilities compared to previous generation serial controllers, offering improved throughput for high-speed serial applications.

Specialized Replacement Considerations

Z8523010VSC is a confirmed substitute within the same product family.
