ISPLSI2032-150LT44

Overview

The ISPLSI2032-150LT44 is an in-system programmable high-density PLD from the ispLSI 2000 family. It features 1000 PLD gates, 32 I/O pins with two dedicated inputs, and 32 registers. Built on E2 CMOS technology, it supports a maximum clock frequency of 100 MHz with a propagation delay of 10 ns. The device operates at a rated supply voltage of 5 V (range 4.75 V to 5.25 V) and is housed in a 44-terminal TQFP package.

Feature Summary

• High Density: 1000 PLD gates with 32 I/O pins and 32 registers.
• In-System Programmability: Supports programming via JTAG without removing from the board.
• E2 CMOS Technology: Non-volatile configuration memory allows instant-on operation.
• Global Interconnect: High-speed routing pool for fast counters and state machines.

Applications

• SDRAM controller implementation
• Address decoding logic
• State machine design
• Bus bridging applications

Procurement Notes

Verify the specific suffix 'LT44' corresponds to the commercial temperature range and TQFP-44 package. Confirm the manufacturer source, as some listings attribute this part to All Sensors while Lattice Semiconductor is the original designer. Ensure the document date aligns with current availability status.

Selection Notes

Select this model for designs requiring 1000 PLD gates and 32 I/Os. The -150 speed grade indicates a 10 ns propagation delay. Compare against the ispLSI2032A variant if advanced 0.35 micron technology or form/function compatibility updates are required for new designs.

Part Context

This component belongs to the Lattice ispLSI 2000 series of high-density PLDs. It utilizes E2 CMOS technology for non-vatile storage. The device is functionally compatible with the ispLSI2032 but may differ in manufacturing process node compared to the 'A' suffix variants.

Replacement Considerations

The ispLSI2032A-150LT44 is fully form and function compatible with identical timing specifications. Verify pinout and electrical parameters match before substitution.
