Z8523010PEG

Specialized Overview

The Z8523010PEG is an Enhanced Serial Communications Controller (ESCC) manufactured by Zilog. It features a Z80-compatible bus interface and operates at a maximum clock frequency of 10 MHz. The device includes two independent serial channels, each equipped with a 4-byte transmit FIFO and an 8-byte receive FIFO. It supports asynchronous, synchronous bit, byte, HDLC, SDLC, BISYNC, and X.25 protocols. Electrical characteristics include a 5V operating voltage and standard TTL levels for data inputs and outputs. The component is housed in a 44-pin PLCC package.

Specialized Feature Summary

• Supports multiple communication protocols including SDLC, HDLC, and asynchronous modes
• Integrated FIFO buffers reduce CPU overhead for data transfer
• Provides vectored interrupt capabilities with daisy-chain support
• Compatible with Z80 microprocessor bus architecture

Specialized Applications

• Network controller interfaces requiring serial data handling
• Modem control systems utilizing modem status lines
• Embedded systems needing high-speed serial communication ports

Specialized Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature range. Confirm availability status as distribution may vary. Ensure compatibility with existing system voltage requirements before integration.

Specialized Selection Notes

Select this component when a Z80-compatible serial controller with integrated FIFOs is required. Compare against the Z80230 variant if address/data multiplexing is preferred over separate data/address buses. Verify pinout compatibility with the target PCB layout.

Specialized Part Context

This part belongs to the Z85230/L series of Enhanced Serial Communications Controllers. It shares functional similarities with the Z80230 but utilizes a distinct non-multiplexed bus interface. The PEG suffix typically denotes a specific package and environmental rating within the Zilog product line.

Specialized Replacement Considerations

Publicly confirmed substitutes are not available in the provided documentation. Consider the Z85C30 series for multi-protocol controller applications or the Z80230 for Z80-bus compatible alternatives.
