Z84C4410VEC

Specialized Overview

The Z84C4410VEC is a CMOS Serial Input/Output (SIO) controller manufactured by Zilog, belonging to the Z84C44 series. It integrates two independent asynchronous serial channels and a programmable baud rate generator on a single chip. The device operates with a maximum clock frequency of 10 MHz and requires a 5 V supply voltage. It utilizes an 8-bit data bus width for communication with host processors. The component is housed in a 44-pin PLCC package and supports surface mount installation. It functions as a dedicated interface IC for managing serial data transmission and reception tasks.

Specialized Feature Summary

• Integrates dual asynchronous serial communication channels for simultaneous data handling
• Includes a programmable baud rate generator for flexible timing control
• Provides direct interface capability between microprocessors and serial peripheral devices

Specialized Applications

• Serial communication interfaces in embedded control systems
• Data acquisition systems requiring multiple serial ports
• Industrial automation controllers needing reliable UART connectivity

Specialized Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Ensure storage conditions meet specified humidity requirements to prevent damage before soldering. Review end-of-life notifications if sourcing from secondary markets.

Specialized Selection Notes

Select this component when designing systems requiring two independent serial ports without external logic. Compare against other Z84C44 variants based on required clock speeds and package types. Ensure the host processor supports the necessary control signals for SIO operation. Verify voltage levels match the system's 5 V logic standard.

Specialized Part Context

This part belongs to the Zilog Z84C44 family of serial I/O controllers, which are designed to offload serial communication tasks from the main CPU. These components were widely used in legacy computing and industrial applications before the prevalence of integrated USB and Ethernet controllers. The Z84C4410VEC specifically offers high-speed performance within this lineage.

Specialized Replacement Considerations

Direct pin-to-pin replacements may be limited due to the discontinued status of many Zilog SIO parts. Evaluate modern UART controllers or multi-port USB-to-serial adapters as functional alternatives. Check compatibility with existing firmware drivers when substituting with different serial controller architectures.
