Description
Zilog Z0847004PSC Z80 DART Dual Async Receiver Transmitter IC Chip DIP-40
The Zilog Z0847004PSC is a Z80 DART — Dual Asynchronous Receiver/Transmitter — a serial communications controller IC from Zilog's classic Z80 family. It provides two independent full-duplex serial channels capable of operating in both synchronous and asynchronous modes, designed to interface directly with the Z80 CPU bus. The date code on this chip reads 8929, placing its manufacture in the 29th week of 1989. This is new old stock — the chip was manufactured but never installed or used.

Applications
The Z80 DART was a core serial communications peripheral in Z80-based computer systems of the late 1970s and 1980s. It was used in early personal computers, industrial controllers, embedded systems, and single-board computers that relied on the Z80 CPU architecture, providing RS-232 serial port functionality and synchronous communications links. Systems such as the Kaypro, Osborne, TRS-80, and many industrial Z80 SBC designs used the DART or its close relative, the Z80 SIO, to handle serial I/O. Today the Z0847004PSC is sought by retrocomputing enthusiasts restoring vintage Z80 machines, hobbyists building Z80-based homebrew computers, and engineers maintaining legacy industrial equipment that still runs Z80-based control systems. NOS (new old stock) examples like this are particularly valued because they are unaged electrically and have never been soldered, making them preferable for restoration and new builds alike.
This Zilog Z0847004PSC Z80 DART IC is new old stock (NOS) — manufactured but never used or installed. The chip is out of its original packaging and has been stored, but shows no signs of use or damage. Pins are straight and clean with no bending or oxidation visible. This is the chip only, with no original packaging or tube. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
