Z0220112VECR3470

Overview

The Z02201 is a synchronous single-chip V.22bis data pump with an integrated Analog Front-End (AFE). It supports full-duplex throughput up to 2400 bps over dial-up lines, complying with ITU V.22bis, V.23, V.22, V.21, Bell 212A, and Bell 103 standards. The device operates on a single +5 VDC supply with typical current consumption of 50 mA. It features a 16-bit DSP core running at 12.288 MHz, parallel host interface for 8-bit microprocessors, and serial synchronous data transfer. Available in 44-pin PLCC and LQFP packages, it includes HDLC framing, programmable tone detectors, and adaptive equalization.

Feature Summary

• Integrated AFE with 12-bit resolution ADC/DAC and built-in filters
• Supports multiple modulation schemes including FSK, DPSK, and QAM
• Programmable bi-quad tone detectors for call-progress monitoring
• Direct parallel interface compatibility with standard 8-bit microprocessors

Applications

• Embedded modem applications requiring space and low power efficiency
• Data communication over Public Switched Telephone Network (PSTN)
• Industrial control systems utilizing V.22bis or Bell series protocols

Procurement Notes

Verify the specific package variant required, as the Z02201 is available in both PLCC-44 and LQFP-44 configurations. Confirm that the ordering suffix corresponds to the desired thermal and mechanical specifications. Ensure compatibility with the host microprocessor's voltage levels and timing requirements before finalizing procurement.

Selection Notes

Select the Z02201 when a complete modem solution with integrated analog front-end is needed. It eliminates external filtering components and reduces board space compared to discrete solutions. Consider the parallel interface for direct microprocessor access or the serial interface for data transfer. Verify temperature range requirements against the commercial 0°C to +70°C specification.

Part Context

The Z02201 belongs to ZiLOG's family of synchronous modem controllers designed for embedded communications. It integrates the data pump logic and analog front-end into a single silicon die, simplifying design complexity. This component is part of the broader portfolio of network controller and processor ICs aimed at cost-effective PSTN connectivity solutions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should evaluate pin-compatible alternatives only if official cross-reference data from the manufacturer is obtained.
