Z8023010VSG

Specialized Overview

The Z8023010VSG is an Enhanced Serial Communications Controller (ESCC) manufactured by Zilog. It features a Z80-compatible multiplexed address/data bus interface and operates within a supply voltage range of 4.5V to 5.5V. The device supports data transfer rates up to 0.625 MBps with a maximum clock frequency of 10 MHz. 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 vectored interrupts and DMA control for efficient system data handling
• Includes dedicated transmit and receive FIFO buffers to reduce CPU overhead
• Provides hardware support for SDLC, BISYNC, and asynchronous protocols

Specialized Applications

• Serial data communications systems requiring high throughput
• Microprocessor peripheral interfaces for embedded controllers
• Modem and terminal equipment signal processing

Specialized Procurement Notes

Verify the specific suffix 'VSG' against the manufacturer's current ordering information to confirm package type and environmental compliance status. Ensure that the component meets all applicable RoHS directives relevant to the intended deployment region before finalizing procurement orders.

Specialized Selection Notes

Select this component when a Z80-bus compatible serial controller is required. Verify that the system design accommodates the 44-pin PLCC footprint and that the operating voltage aligns with the specified 4.5V to 5.5V range. Confirm that the 10 MHz clock speed satisfies the timing requirements of the target application.

Specialized Part Context

This part belongs to the Z80230 family of ESCCs, which are enhanced versions of the earlier Z80C30 series. The Z80230 variant specifically integrates a Z80-style bus interface, distinguishing it from the Z85230 family which uses a standard microprocessor bus. This integration simplifies interfacing with legacy Z80-based architectures.

Specialized Replacement Considerations

The Z8523010VSG offers identical functional capabilities but utilizes a different bus interface architecture. Substitution requires verifying compatibility with the host processor's bus protocol.
