Z1601720ASC1868

Specialized Overview

The Z16017 is a PCMCIA interface adapter chip designed for the card side of the interface. It operates from a 3.0V to 5.5V power supply and supports speeds up to 20MHz. The device includes 256 bytes of on-chip RAM for attribute memory and configuration registers. It is housed in a 100-Pin VQFP package.

Specialized Feature Summary

• Supports PCMCIA Configuration Registers and internal EEPROM sequencer for master mode programming.
• Features Serial Peripheral Interface (SPI) circuitry allowing control through a local microprocessor in slave mode.
• Provides translation between PCMCIA and I/O peripherals, as well as ATA/IDE mapping and pass-through modes.

Specialized Applications

• Ethernet controllers
• Universal Asynchronous Receiver/Transmitters (UART)
• Modems
• Rotating disk memory

Specialized Procurement Notes

Verify the specific suffix against the manufacturer's datasheet PS012002-1201 to confirm pinout variations or environmental ratings. Confirm that the required EEPROM content matches the device's initialization requirements if using Master mode. Ensure the host system provides the necessary clock signals if operating in Slave mode.

Specialized Selection Notes

Select the Z16017 when a dedicated PCMCIA adapter solution is required for peripheral integration. Consider the Z86017 variant if the specific electrical characteristics or pin assignments differ for the target application. Verify compatibility with the intended peripheral bus protocols before finalizing the component choice.

Specialized Part Context

The Z16017 belongs to the ZX6017 family, which also includes the Z86017 and mirror image variants Z86M17 and Z16M17. These chips are general-purpose adapters used to connect various memory and I/O peripherals to PCMCIA slots. The Z16017 specifically offers on-chip generation of IOIS16 in I/O mode.
