Z0853008VSG

Specialized Overview

The Z0853008VSG is a Serial Communication Controller (SCC) from the Z08530 series manufactured by ZiLOG. It operates at a clock frequency of 8 MHz and supports asynchronous, synchronous byte, HDLC, SDLC, X.25, BISYNC, and extended synchronous protocols. The device features NRZ, NRZI-Space, Biphase-Mark (FM1), Biphase-Space (FM0), and Manchester encoding/decoding capabilities. It includes a 10x19 frame status FIFO and modem control I/Os usable as general-purpose I/Os. Electrical specifications include a minimum supply voltage of 4.75 V, a maximum of 5.25 V, and an operating temperature range of 0°C to +70°C. It is housed in a 44-PLCC surface-mount package.
