Z0220516PSG1961

Overview

The Z02205 is a V.22bis modem controller manufactured by Zilog, designed for embedded applications requiring low power consumption and compact size. It features an on-chip ROM containing the AT command set interpreter, 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 capabilities. The controller provides a glueless interface to the Z02201 data pump and is available in 28-pin DIP and SOIC packages.

Feature Summary

• Integrated AT command set interpreter stored in on-chip ROM
• Glueless interface capability with Z02201 data pump
• Supports both synchronous and asynchronous operation modes
• Includes programmable Watch-Dog Timer and Power-On Reset circuitry

Applications

• Embedded V.22bis modem systems
• Low-power communication devices
• Compact size requirement applications

Procurement Notes

Verify package type availability as the component is offered in 28-pin DIP and SOIC configurations. Confirm that the firmware matches the target country's telephone network requirements, as standard samples are tailored for North America. Ensure the design accommodates the required phone line interface and DTE connections to complete the modem system.

Selection Notes

Select this controller when a dedicated V.22bis solution with integrated command processing is required. It is suitable for designs prioritizing reduced bill of materials by removing external memory. Verify compatibility with the Z02201 data pump for optimal integration. Consider the operating temperature range and voltage specifications against the final application environment.

Part Context

The Z02205 belongs to Zilog's family of modem controllers, specifically engineered for V.22bis standards. It complements the Z02201 data pump to form a complete modem solution. This component addresses market needs for cost-effective, space-constrained communication modules by integrating essential control logic and firmware directly onto the silicon die.
