Z16M1720ASC1868

Specialized Overview

The Z16M1720ASC1868 is a PCMCIA adapter chip from the ZX6017 family, designed for card-side interface applications. It features 256 bytes of on-chip RAM and operates at speeds up to 20 MHz within a 100-pin VQFP package. The device supports a 3.0V to 5.5V power supply range and conforms to PCMCIA standards. As a mirror image variant (Z16M17), it provides specific pinout configurations suitable for diverse board layouts while maintaining compatibility with standard PCMCIA memory and I/O mapping peripherals.

Specialized Feature Summary

• Supports PCMCIA configuration registers and attribute memory management
• Includes an internal EEPROM sequencer for automatic initialization in master mode
• Provides serial peripheral interface (SPI) control capabilities for slave mode operation
• Enables ATA/IDE pass-through and translation functions

Specialized Applications

• Ethernet controller integration on PCMCIA cards
• Universal Asynchronous Receiver/Transmitter (UART) implementations
• Modem connectivity solutions
• Rotating disk memory storage devices

Specialized Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature rating. Ensure the mirror image bond-out option aligns with your PCB layout requirements. Confirm RoHS compliance status through current manufacturer declarations before finalizing procurement.

Specialized Selection Notes

Select this component when a dedicated PCMCIA interface solution is required without a local microprocessor. The Z16M17 variant is specifically chosen for its mirror image pin configuration, which may simplify routing compared to standard versions. Evaluate the need for ATA/IDE pass-through capabilities if interfacing with storage devices.

Specialized Part Context

This part belongs to the Z86017/Z16017 series, known as the ZX6017 PCMCIA Interface Solution. The Z16M17 designation indicates a mirror image bond-out option within this family. These chips are general-purpose adapters used to bridge PCMCIA slots with various peripheral buses, including ATA/IDE and generic I/O interfaces.

Specialized Replacement Considerations

The Z86M17 serves as a functional equivalent within the same family, sharing identical specifications but potentially differing in pinout orientation due to the mirror image design. Verify electrical characteristics and timing diagrams to ensure compatibility with existing system constraints.
