Z0847004PSG

Specialized Overview

The Z0847004PSG is a UART interface integrated circuit manufactured by Zilog, belonging to the Z08470 series. It is designed as a DART (Digital Asynchronous Receiver/Transmitter) utilizing NMOS technology. The component supports a clock frequency of 4 MHz and is housed in a 40-pin Dual In-line Package (PDIP-40). It is intended for through-hole mounting on printed circuit boards. The device functions as a serial communication controller, providing essential interface capabilities for microprocessor systems requiring asynchronous data transmission and reception.

Specialized Feature Summary

• Implements Digital Asynchronous Receiver/Transmitter (DART) functionality for serial data handling
• Utilizes NMOS semiconductor process technology for internal logic operations
• Supports standard UART protocol requirements for asynchronous communication

Specialized Applications

• Microprocessor-based systems requiring serial I/O expansion
• Industrial control equipment with legacy Z80 architecture compatibility
• Embedded systems needing dedicated asynchronous receiver/transmitter interfaces

Specialized Procurement Notes

Verify the specific manufacturing origin and RoHS compliance status directly with the supplier or manufacturer documentation before procurement. Confirm that the PDIP-40 package dimensions match the target PCB footprint. Ensure the 4 MHz operational requirement aligns with the system clock design. Check for any obsolescence notices or lifecycle changes associated with the Z08470 series from Zilog.

Specialized Selection Notes

Select this component when a dedicated UART controller is required for Z80-compatible or similar microprocessor environments. The choice depends on the need for NMOS-based DART functionality operating at 4 MHz. Consider the physical constraints of the 40-pin DIP package and through-hole assembly processes. Evaluate if the specific interface characteristics meet the baud rate and framing requirements of the target application without external multiplexing.
