Z8523010PSG

Specialized Overview

The Z8523010PSG is a Serial Communication Controller from the Zilog Z85230 family, designed for high-performance serial data communications. It features two independent channels supporting asynchronous and synchronous protocols including SDLC, HDLC, and BISYNC. The device utilizes a 40-pin Dual In-line Package (PDIP) with through-hole mounting. It operates on a single 5V supply voltage ranging from 4.5V to 5.5V. The component supports an external clock input via PCLK and includes integrated FIFO buffers for efficient data handling.

Specialized Feature Summary

• Dual-channel architecture providing independent serial communication paths for simultaneous data transmission and reception.
• Supports multiple standard protocols including Asynchronous, Synchronous Byte, Synchronous HDLC, and SDLC modes.
• Integrated interrupt daisy-chaining capability allowing priority management in multi-device systems.
• Configurable baud rate generator and digital phase-locked loop for flexible clock synchronization.

Specialized Applications

• Radar relay equipment maintenance platforms requiring robust serial interface capabilities.
• Embedded systems needing reliable asynchronous and synchronous serial data transfer.
• Industrial control systems utilizing modem control signals and DMA integration.

Specialized Procurement Notes

Verify the specific suffix 'PSG' against current manufacturer documentation to confirm package type and lead time status. Ensure compatibility with existing PCB footprints for 40-pin DIP configurations. Check for moisture sensitivity levels if storage conditions exceed specified limits. Confirm RoHS compliance requirements against the latest environmental declarations provided by the supplier.

Specialized Selection Notes

Select this component when a dual-channel serial controller with Z80 or Z85 bus interface compatibility is required. Consider the PDIP package only if through-hole assembly is mandated by mechanical constraints. Evaluate system timing requirements against the AC characteristics defined in the datasheet. Ensure the host processor can support the necessary interrupt acknowledge cycles for optimal performance.

Specialized Part Context

This part belongs to the Z85230 Enhanced Serial Communications Controller (ESCC) family. It serves as a peripheral interface between microprocessors and serial devices. The Z85230 variant specifically uses a non-multiplexed address/data bus, distinguishing it from the Z80230 which uses multiplexed lines. This family is widely used in legacy and specialized embedded applications requiring precise serial protocol handling.

Specialized Replacement Considerations

The Z85C30 series offers similar functionality but may differ in bus interface specifics and pinout arrangements. Verify electrical compatibility and register mapping before substitution. The Z80230 is functionally equivalent regarding serial features but requires adaptation for its multiplexed bus architecture. Consult official cross-reference guides for definitive replacement validation.
