Z0221524ASGR50A5

Overview

The Z02215 is a single-chip modem integrated circuit manufactured by ZiLOG, designed for embedded applications requiring space efficiency and low power consumption. It integrates a controller, data pump, and Analog Front End (AFE) with an active hybrid circuit. The device supports synchronous full-duplex communication at data rates up to 2400 bps over dial-up lines, complying with ITU V.22bis, V.22, V.23, V.21, Bell 212A, Bell 202, Bell 202T, and Bell 103 standards. It operates on a single +5 VDC supply with a typical current draw of 60 mA. The component is available in a 44-lead LQFP package and supports both parallel and serial host interfaces.

Feature Summary

• Integrates a complete modem solution including controller, DSP, and analog front end with active hybrid circuitry.
• Includes an on-chip ROM-based AT command interpreter eliminating the need for external memory.
• Supports dynamic power management with SLEEP modes to reduce consumption during idle periods.
• Features adaptive equalization and programmable call progress tone detectors for diverse line conditions.

Applications

• Embedded modem systems for Public Switched Telephone Network (PSTN) connectivity.
• North American Type-I Caller ID devices.
• Minitel line reversal terminals supporting V.23 protocols.

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, as this is determined by the S/P pin state rather than the part number itself. Ensure availability of the 44-lead LQFP footprint in the target design.

Selection Notes

Select this component for designs prioritizing minimal external logic and reduced board space. The internal AFE reduces the need for discrete filtering components. Verify that the application environment falls within the standard operating temperature range of 0°C to +70°C, or select extended temperature variants if necessary. Ensure the host processor can support either the parallel or serial interface timing requirements.

Part Context

The Z02215 belongs to the Z02215 series of single-chip modems from ZiLOG. It is specifically engineered for V.22bis compatibility and offers a self-contained modem solution. The device distinguishes itself by combining digital signal processing with analog front-end functions on a single die, facilitating straightforward integration into telecommunication equipment without complex external circuitry.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult the manufacturer's latest product specification for potential obsolescence notices or recommended upgrades within the same family.
