ISPLSI 2032VE-180LT44I

Complex Programmable Logic Devices Overview

The ispLSI 2032VE-180LT44I is a discontinued high-density programmable logic device from Lattice Semiconductor. It features 1000 PLD gates, 32 I/O pins, and 32 registers within a single Megablock architecture. Operating at a maximum frequency of 180 MHz with a propagation delay of 5.0 ns, it utilizes E2CMOS technology for non-volatile reprogrammability. The device supports 3.3V systems while interfacing with 5V TTL levels. It includes three dedicated clock inputs, one global output enable pin, and boundary scan testability via IEEE 1149.1. The 'I' suffix denotes the industrial temperature grade, and 'LT44' indicates the 44-pin TQFP package.

Complex Programmable Logic Devices Feature Summary

• High Density SuperFAST Architecture: 1000 PLD gates, 32 universal I/Os, and 32 registers in a single Megablock.
• E2CMOS Technology: Non-volatile, electrically erasable/reprogrammable with 10,000 erase cycles.
• In-System Programmability: Supports 3.3V ISP via Boundary Scan Test Access Port (TAP).
• Mixed Voltage Interface: Compatible with standard 5V TTL devices despite 3.3V operation.

Complex Programmable Logic Devices Applications

• Complex state machine implementation requiring fast global interconnectivity.
• Address decoding and wide input gating applications.
• Prototyping designs using legacy ispLSI 2032V pinout compatibility.
• Systems requiring non-volatile reconfiguration of logic functions.

Complex Programmable Logic Devices Procurement Notes

This specific part number is officially discontinued per Product Change Notification #09-10. Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory channels. No new production units are manufactured by Lattice Semiconductor. Designers should confirm end-of-life status before finalizing procurement plans.

Complex Programmable Logic Devices Selection Notes

Select this component only if existing designs mandate the ispLSI 2032VE architecture or require pin-compatible replacement for older 2032V parts. For new designs, Lattice recommends the ispLSI 2032VE-300 series due to higher performance capabilities. Ensure the design toolchain supports the specific speed grade (-180) and industrial temperature range associated with the 'I' suffix.

Complex Programmable Logic Devices Part Context

The ispLSI 2032VE belongs to the SuperFAST family of in-system programmable logic devices. This model represents the 180 MHz speed bin within the commercial/industrial lineup. It shares architectural similarities with the ispLSI 2032V but offers enhanced density and lower voltage operation. The device integrates Generic Logic Blocks (GLBs) connected via a Global Routing Pool for optimized signal distribution.

Complex Programmable Logic Devices Replacement Considerations

Direct functional substitutes are limited due to discontinuation. The ispLSI 2032VE-300LT44I offers identical pinout and architecture with improved timing specifications (3.0 ns tpd). Other Lattice MachXO or CrossLink-N families provide modern FPGA alternatives but require schematic and layout redesigns due to differing pinouts and configuration methods.
