Z0220516SSC

Overview

The Z02205 is a V.22bis modem controller manufactured by ZiLOG, designed for embedded applications requiring low power consumption and small size. It features an integrated AT command set interpreter stored in on-chip ROM, eliminating the need for external memory. The device supports both tone and pulse dialing, call progress monitoring, handshake controls, guard tones, line quality monitoring with auto-retrain, and Type-I Caller ID. It operates within a voltage range of 4.5V to 5.5V and includes dynamic power management capabilities. The controller offers a glueless interface to the Z02201 data pump and is available in 28-pin DIP or SOIC packages.
