Z0221524VSGR4508

Overview

The Z02215 is a synchronous single-chip V.22bis modem designed for embedded applications requiring space efficiency and low power consumption. It integrates a modem controller, DSP, and Analog Front End (AFE) with an active hybrid circuit. The device supports full-duplex data transmission at rates up to 2400 bps over dial-up lines on the Public Switched Telephone Network (PSTN). It operates on a single +5 VDC power supply and includes programmable country parameters via AT commands or an EEPROM interface. The component features dynamic power management with SLEEP modes and supports multiple modulation standards including V.22bis, V.23, V.22, V.21, Bell 212A, Bell 103, and Bell 202.

Feature Summary

• Integrates a complete modem solution with an on-chip controller, data pump, and analog front end featuring an active hybrid circuit.
• Includes an internal ROM-based AT command set interpreter, eliminating the need for external memory components.
• Supports comprehensive tone generation and detection capabilities, including programmable bi-quad call progress tone detectors.
• Features adaptive equalization to compensate for adverse line conditions and automatic compromise equalizers for optimized performance.

Applications

• Embedded modem applications where physical space constraints are critical
• Public Switched Telephone Network (PSTN) communication systems
• Voice answer detection systems utilizing line-in-use and pick-up detection

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm temperature range and package type. Confirm that the required interface mode (Serial or Parallel) matches the hardware configuration of the host system. Ensure compatibility with the intended Data Access Arrangement (DAA) for proper analog signal interfacing.

Selection Notes

Select this component for designs requiring a self-contained V.22bis modem solution without external memory. Evaluate the host processor's capability to interface via the available Serial or Parallel Host Interface options. Consider the environmental operating temperature requirements when choosing between standard and extended temperature variants.

Part Context

The Z02215 belongs to the Z02215 series of single-chip modems manufactured by ZiLOG. This family is engineered specifically for telecommunications equipment and embedded control systems. The device consolidates functions typically distributed across multiple chips into a single integrated circuit to reduce system complexity and component count.

Replacement Considerations

Consult the manufacturer's datasheet for officially confirmed substitute part numbers. Verify pinout compatibility and electrical specifications before considering alternative models from other manufacturers.
