Z1601720ASG1868

Specialized Overview

The Z1601720ASG1868 is a PCMCIA interface solution manufactured by Zilog, belonging to the ZX6017 family. It operates within a 3.0V to 5.5V power supply range and supports speeds up to 20MHz. The device features 256 bytes of on-chip RAM for attribute memory storage. It is housed in a 100-pin VQFP package. The component conforms to PCMCIA standards and includes an internal EEPROM sequencer for configuration.

Specialized Feature Summary

• Supports PCMCIA Configuration Registers and ATA/IDE translation modes
• Includes an internal EEPROM sequencer for automatic programming via SPI
• Provides serial peripheral interface control through local microprocessor slave mode
• Features on-chip generation of IOIS16 signals in I/O mode

Specialized Applications

• PCMCIA adapter chips used on the card side of the interface
• Configuration for access to Ethernet controllers and Universal Asynchronous Receiver/Transmitters (UART)
• Integration with modems and rotating disk memory peripherals

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout variations or temperature ratings. Confirm RoHS compliance status as older Zilog products may not meet current environmental directives. Ensure the required external EEPROM or microprocessor interface matches the selected Master or Slave operational mode.

Specialized Selection Notes

Select this component when designing PCMCIA cards requiring direct ATA/IDE or I/O peripheral mapping without a host processor. Consider the Z86017 variant if mirror image bond-out options are needed for layout flexibility. Verify that the system clock frequency does not exceed the 20MHz limit defined in the electrical characteristics.

Specialized Part Context

This part belongs to the Z86017/Z16017 series of general-purpose PCMCIA adapter chips. The 'Z16' prefix typically denotes specific manufacturing revisions or speed grades within the ZX6017 family. These devices are designed to bridge PCMCIA slots with various peripheral buses, simplifying card design by handling protocol translation internally.

Specialized Replacement Considerations

The Z86017 serves as the primary functional equivalent within the same product family. Mirror image variants such as the Z86M17 or Z16M17 offer identical functionality with alternative pin configurations for board layout optimization.
