Z0220516SSCR4292

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 tone or pulse dialing, call progress monitoring, handshake controls, guard tones, line quality monitoring with auto-retrain, and Type-I Caller ID. It operates within a 4.5V to 5.5V voltage range and includes dynamic power management with standby modes. The controller provides a glueless interface to the Z02201 data pump and is available in 28-pin DIP and SOIC packages.

Procurement Notes

Verify package type (DIP or SOIC) and temperature grade against project requirements. Confirm firmware configuration matches target country telephone network standards, as standard samples are tailored for North America. Check RoHS compliance status if required by local regulations.

Selection Notes

Select based on required operating temperature range and package style. Ensure compatibility with Z02201 data pump for complete modem functionality. Consider external crystal requirements for clock generation. Verify S-register configurations for specific regional signaling standards.

Part Context

The Z02205 belongs to Zilog's modem controller family, specifically optimized for V.22bis protocols. It complements the Z02201 data pump to form a complete modem solution. This component targets cost-sensitive and space-constrained embedded markets where low power consumption is critical.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Evaluate alternative V.22bis controllers based on pinout compatibility and AT command set support.
