Z0220516SSC1961

Overview

The Z02205 is a V.22bis modem controller designed for embedded applications requiring low power consumption and small size. It features an on-chip ROM containing the AT command set interpreter, eliminating the need for external memory. The device operates at a speed of 16 MHz with 16 KB of ROM and 237 bytes of RAM. It supports a 4.5V to 5.5V operating range and functions within a commercial temperature range of 0°C to +70°C. Available in 28-pin DIP and SOIC packages, it provides a glueless interface to ZiLOG data pumps like the Z02201.

Feature Summary

• Includes on-chip ROM with AT command set interpreter for direct control without external memory
• Supports tone or pulse dialing, auto-dial, auto-answer, and call progress monitoring
• Features dynamic power management with HALT and STOP modes for low power consumption
• Provides a glueless parallel interface to ZiLOG data pump devices

Applications

• Embedded V.22bis modem systems
• Low power consumption communication devices
• Small size requirement applications

Procurement Notes

Verify the specific package type (DIP or SOIC) and country configuration requirements before procurement. Production usage may require modifying controller code to meet local telephone network standards outside North America. Confirm compatibility with the intended ZiLOG data pump model for the glueless interface.

Selection Notes

Select this component for V.22bis modem controller roles where integrated AT command processing reduces system complexity. Ensure the application environment stays within the 0°C to +70°C commercial temperature range. Verify that the 4.5V to 5.5V supply voltage aligns with the system design constraints.

Part Context

The Z02205 serves as the central controller for ZiLOG's V.22bis modem solutions. It is typically paired with data pumps such as the Z02201 or Z02922 to form a complete modem system. The device handles protocol logic, allowing the data pump to focus on signal modulation and demodulation.
