Application Scenarios & Design Considerations

Low cost field programmable microcontroller peripherals, 150ns

Alternative Part Number

  • MACH211SP-15VC --: Pin-compatible CPLD with comparable 15 ns speed grade and similar logic capacity, suitable drop-in replacement for the PSD3xx configurable system device.
  • ATF1502AS-15JC --: 15 ns CPLD in PLCC package offering equivalent programmable logic and I/O resources, commonly used as a substitute for WSI PSD devices.
  • EPM7032LC44-15 --: Classic 15 ns MAX 7000 CPLD in 44-pin PLCC with similar macrocell count and timing, widely available alternative for legacy WSI PSD designs.
  • PSD313-B-15J --: Same PSD3xx family from ST/WSI with comparable configuration and 15 ns speed grade; pin-compatible in most designs.
  • PSD312-B-15L --: Equivalent PSD312 device in a different package option, same 15 ns timing and programmable logic/memory architecture.
  • PSD311-B-15J --: Lower-density member of the same PSD3xx series with identical interface and 15 ns speed, usable where reduced logic/memory resources are acceptable.
