ISPLSI 2032A-135LJ44

Complex Programmable Logic Devices Overview

The ispLSI2032A-135LJ44 is a high-density, in-system programmable logic device (PLD) manufactured by Lattice Semiconductor. It features 1000 PLD gates, 32 universal I/O pins, two dedicated inputs, and three dedicated clock inputs within a 44-pin Plastic Leaded Chip Carrier (PLCC) package. Built on advanced 0.35-micron E2CMOS technology, the device supports a maximum operating frequency of 137 MHz with a typical propagation delay of 8.0 ns. It offers non-volatile reprogrammability, TTL-compatible I/O levels, and programmable output slew rate control to minimize switching noise.

• Advanced Technology: Fabricated using 0.35 Micron E2CMOS technology for high performance and low power.
• Flexible Clocking: Features three dedicated clock input pins (Y0, Y1, Y2) and asynchronous clock options.

Complex Programmable Logic Devices Applications

• Address decoding and bus bridging in embedded systems.
• State machine implementation for industrial control logic.
• Fast counter applications utilizing wide input gating capabilities.
• Glue logic replacement in legacy digital circuit designs.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or Lattice Semiconductor directly. Confirm the specific speed grade (-135) and package type (LJ44 indicates 44-pin PLCC) match design requirements. Check for lead-free variants if environmental compliance is mandatory. Ensure programming tools support the ispLSI architecture for successful configuration.

Complex Programmable Logic Devices Selection Notes

Select the -135 speed grade when a maximum toggle frequency of 137 MHz is required. The LJ44 suffix denotes a standard plastic PLCC package; use LT44 for TQFP alternatives. Consider the ispLSI2032E for new designs as recommended by the manufacturer. Evaluate power consumption estimates based on product term usage and operating frequency before finalizing the selection.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 2032/A family of high-density PLDs. It is functionally compatible with the original ispLSI 2032 but utilizes an advanced 0.35-micron process. The device serves as a bridge between simple discrete logic and complex FPGAs, offering reconfigurability with PLD-like ease of use. It is part of Lattice's legacy programmable logic portfolio.

Complex Programmable Logic Devices Replacement Considerations

The datasheet explicitly recommends using the ispLSI2032E for new designs. Direct pin-to-pin replacements within the same family include the ispLSI2032A-110LJ44 (slower) or ispLSI2032A-150LJ44 (faster), provided timing constraints allow. Verify that any substitute maintains the 44-pin PLCC footprint and 5V ISP compatibility.
