Z84C4206PEC

Specialized Overview

The Z84C4206PEC is an I/O controller interface IC from the Zilog Z84C42 series, designed for serial communication applications. It integrates two synchronous/asynchronous serial I/O channels (SIO/2) on a single CMOS chip. The device operates with a maximum clock frequency of 6 MHz and requires a 5V supply voltage. It features an 8-bit data bus width and supports industrial temperature ranges from -40°C to +100°C. The component is housed in a 40-pin Dual In-line Package (DIP-40) for through-hole mounting.

Specialized Feature Summary

• Integrates dual serial I/O channels supporting both synchronous and asynchronous modes
