Z84C4210PEG

Specialized Overview

The Z84C4210PEG is a serial I/O controller manufactured by Zilog, designed for high-speed data communication in embedded systems. It features two independent serial channels capable of operating at a maximum clock frequency of 10 MHz and a maximum data transfer rate of 0.25 MBps. The device utilizes CMOS technology and supports an external 8-bit data bus width, ensuring compatibility with Z80-based architectures. It operates within a supply voltage range of 0 V to 5 V and functions reliably across an industrial temperature range from -40 °C to +100 °C. The component is housed in a 40-pin DIP package.

Specialized Feature Summary

• Dual-channel serial interface architecture supporting simultaneous asynchronous and synchronous operations
• Comprehensive protocol support including HDLC, SDLC, X.25, BISYNC, and byte/bit-oriented synchronization modes
• Integrated low-power operational mode for energy-efficient system management

Specialized Applications

• Industrial automation control systems requiring robust serial communication
• Embedded data acquisition networks utilizing Z80 microprocessor families
• Telecommunications equipment implementing HDLC or SDLC protocols

Specialized Procurement Notes

Verify the specific suffix PEG against official Zilog documentation to confirm the plastic DIP-40 package variant and commercial/industrial temperature rating. Cross-reference the manufacturer part number with current distributor listings to ensure availability, as legacy components may have limited stock or require alternative sourcing strategies. Confirm RoHS compliance status through the latest environmental declaration documents provided by the manufacturer.

Specialized Selection Notes

Select this component when dual-channel serial connectivity with high throughput is required for Z80-compatible designs. Ensure the application environment stays within the specified -40 °C to +100 °C operating range. Verify that the system power supply remains stable between 0 V and 5 V. Consider the DIP-40 through-hole package constraints during PCB layout if surface-mount alternatives are not suitable for the mechanical assembly requirements.

Specialized Part Context

This part belongs to the Z84C42 series of serial I/O controllers, which are specialized interface chips designed to offload serial communication tasks from the main CPU. These devices complement Zilog's broader portfolio of microprocessors and memory solutions, providing dedicated hardware handling for complex serial protocols without consuming processor cycles.

Specialized Replacement Considerations

The Z84C4206DEE is a documented substitute within the same family, offering identical functionality but rated for a lower maximum clock frequency of 6 MHz. Verify timing requirements before substitution to ensure the slower speed meets the system's data throughput needs.
