Z0220112VEGR3470

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 digital processor running at 12.288 MHz and includes HDLC framing capabilities. The component is available in 44-pin PLCC packages and functions within a commercial temperature range of 0 °C to +70 °C.

Feature Summary

• Integrated AFE with full-duplex voice band processing and 12-bit resolution
• 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 low power consumption
• Data transmission over the Public Switched Telephone Network (PSTN)
• Voice band communication systems utilizing HDLC framing

Procurement Notes

Verify the specific package variant against the required footprint, as the datasheet specifies 44-pin PLCC and LQFP options. Confirm that the operating environment remains within the commercial temperature range of 0 °C to +70 °C. Ensure the host system provides a stable +5 VDC supply with ripple less than 0.1V peak to peak to meet electrical specifications.

Selection Notes

Select this component for designs requiring a complete V.22bis solution without external modems. The integrated AFE reduces bill-of-materials by eliminating external filtering components. Consider the parallel interface requirements if connecting to 8-bit microprocessors like the Z8 or Z80 families. Verify crystal oscillator compatibility with the specified 24.576 MHz frequency for proper clock generation.

Part Context

The Z02201 belongs to ZiLOG's family of network controller and processor ICs designed for communication applications. It serves as a specialized data pump solution distinct from general-purpose microcontrollers. The device integrates both digital signal processing and analog front-end functions into a single silicon die to optimize space and performance in embedded telecommunication products.
