Z0221524VSCR4508

Overview

The Z02215 is a single-chip synchronous modem integrating a controller, data pump, and analog front end. It supports full-duplex operation at 2400 bps over dial-up lines using V.22bis, V.22, V.23, V.21, Bell 212A, Bell 202, Bell 202T, and Bell 103 standards. The device operates on a single +5 VDC supply and features an internal AT command interpreter in ROM. Available in 44-pin PLCC and LQFP packages, it includes dynamic power management with SLEEP modes and supports serial or parallel host interfaces.

Feature Summary

• Integrated Analog Front End with active hybrid circuit for reduced external component requirements
• On-chip AT command set interpreter eliminating the need for external memory
• Supports asynchronous and synchronous terminal data with automatic speed matching
• Built-in adaptive equalization to compensate for adverse line conditions

Applications

• Embedded modem applications requiring space efficiency
• Public Switched Telephone Network (PSTN) communication systems
• Voice answer detection and caller ID implementations

Procurement Notes

Verify package type availability as the datasheet notes specific pinouts for prototype PLCC versions. Confirm temperature range requirements against standard and extended options. Ensure interface mode selection via hardware pins matches system design. Check for updated documentation revisions before finalizing procurement specifications.

Selection Notes

Select based on required operating temperature range and host interface preference. The device supports both serial and parallel modes selectable via hardware. Consider power consumption needs as dynamic power management is available. Verify compatibility with existing Data Access Arrangement (DAA) circuits for analog connections.

Part Context

The Z02215 belongs to Zilog's family of single-chip modems designed for embedded applications. It combines DSP, controller, and AFE functions into one integrated circuit. This consolidation reduces system complexity and board space compared to discrete modem solutions.
