Z8523016VSG

Specialized Overview

The Z8523016VSG is an Enhanced Serial Communications Controller (ESCC) manufactured by Zilog. It operates on a 5V supply with a voltage range of 4.75 V to 5.25 V and supports clock frequencies up to 16 MHz. The device features two independent serial channels, each equipped with a 4-byte transmit FIFO and an 8-byte receive FIFO. It utilizes a PLCC-44 surface-mount package and functions within a commercial temperature range of 0°C to +70°C.

Specialized Feature Summary

• Supports multiple synchronous and asynchronous communication protocols including SDLC, HDLC, and X.25.
• Integrates dedicated FIFO buffers for both transmission and reception to optimize data throughput.
• Provides vectored interrupt capabilities with daisy-chain support for efficient CPU resource management.

Specialized Applications

• High-speed serial data interface design
• Modem control systems
• Network terminal equipment

Specialized Procurement Notes

Verify the specific suffix designation against official documentation to confirm operational parameters such as voltage levels and speed grades. Ensure that the component meets environmental compliance standards required for the target application before finalizing procurement decisions.

Specialized Selection Notes

Select this controller when a CMOS-based solution with integrated FIFOs and flexible bus interfaces is required. Consider the PLCC-44 package constraints and verify compatibility with the host system's clocking requirements and interrupt handling architecture.
