Manufacturer Description

The Cypress Semiconductor PALC16R8 is a high-performance, electrically programmable CMOS Programmable Logic Device (PLD). Utilizing a proprietary N-well CMOS EPROM process, the PALC16R8 offers a superior alternative to traditional bipolar PALs by providing lower power consumption and significantly higher reliability. This device features a sum-of-products (AND-OR) structure that allows users to implement custom logic functions. Unlike one-time-programmable alternatives, the CMOS EPROM technology enables full functional testing and AC/DC characterization by the manufacturer, ensuring extremely high programming yields and field stability.

Technical Specifications

  • Device Type: Registered PLD (Programmable Logic Device)
  • Macrocells: 8 Registered Outputs (Inverting)
  • Technology: Reprogrammable CMOS EPROM
  • Propagation Delay (tPD): 20ns / 25ns / 35ns (Depending on specific suffix)
  • Supply Current (Icc): 45mA (Commercial) / 70mA (Military)
  • Package Options: 20-pin Plastic/Ceramic DIP, SOJ, or LCC
  • Input Protection: >1500V electrostatic discharge (ESD) protection
  • Value-Add: Features "Security Footprint" capability to prevent unauthorized pattern duplication and register preload for simplified system testing.

System Compatibility

The PALC16R8 is a pin-for-pin functional replacement for standard 16R8 bipolar PALs and is compatible with most universal PLD programmers, including:

  • Data I/O 2900 / Unisite
  • BP Microsystems Universal Programmers
  • Vintage Logical Devices / Stag Programmers
  • Standard TTL-level logic environments (5V Vcc)

Applications

Ideal for legacy system maintenance and specialized logic design:

  • Legacy Industrial Control: Replacing obsolete logic in CNC controllers and PLC modules.
  • Medical Computing: Maintenance of late-80s and 90s era diagnostic imaging backplanes.
  • State Machine Implementation: Efficient handling of complex sequential logic and timing control.
  • Glue Logic: Interfacing modern components with legacy 8-bit or 16-bit bus architectures.
