Z0221524ASCR50A5

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 power supply with a standard temperature range of 0°C to +70°C and an extended range of -40°C to +85°C. It features a 44-pin LQFP package and includes an internal oscillator requiring only external crystal components.

Feature Summary

• Integrated controller, DSP, and analog front end with active hybrid circuit
• On-chip ROM containing AT command set interpreter without external memory
• Supports asynchronous and synchronous terminal data with speed matching
• Dynamic power management with SLEEP modes for low-power consumption

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm temperature grade and package type. Ensure compatibility with required interface modes before procurement. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Selection Notes

Select this component for designs requiring a complete modem solution with minimal external logic. Consider the available operating temperature ranges when designing for industrial or commercial environments. Verify that the host system can support either the serial or parallel interface configuration as determined by the hardware pin settings.

Part Context

The Z02215 belongs to the Z02215 series of single-chip modems manufactured by ZiLOG. This family is designed for embedded applications where performance and low power are critical. The device consolidates functions typically found in discrete modem designs into a single integrated circuit.

Replacement Considerations

Consult the manufacturer's datasheet for officially documented compatible substitutes. Verify electrical parameters and pinout compatibility before considering alternative part numbers from other manufacturers.
