ISPLSI 2032VE-110LTN48

Complex Programmable Logic Devices Overview

The ispLSI 2032VE-110LTN48 is a discontinued high-density programmable logic device from Lattice Semiconductor. It features 1000 PLD gates, 32 I/O pins, and 32 registers within an eight Generic Logic Block architecture. Operating at a maximum frequency of 110 MHz with a propagation delay of 10 ns, it utilizes 3.3V E2CMOS technology for non-volatile in-system programming via IEEE 1149.1 boundary scan. The component is housed in a lead-free 48-pin TQFP package.

Complex Programmable Logic Devices Procurement Notes

This specific part number is officially discontinued per Product Change Notification #09-10. Verification of current product status against the manufacturer's discontinuation list is required before procurement attempts. Sourcing should focus on verified surplus channels or qualified alternative components.

Complex Programmable Logic Devices Selection Notes

Select this component only if the design requires the specific 110 MHz speed grade and 48-pin lead-free TQFP form factor. Note that the -110 speed grade offers lower performance than the recommended -300 variant for new designs. Ensure the application supports the 3.3V supply voltage and utilizes the available 32 I/O resources.

Complex Programmable Logic Devices Part Context

The ispLSI 2032VE belongs to the SuperFAST family of Complex Programmable Logic Devices (CPLDs). It is functionally and pinout compatible with the previous ispLSI 2032V series but operates at 3.3V. The device represents Lattice's E2CMOS technology, combining PLD ease of use with FPGA-like density through its reconfigurable interconnect structure.

Complex Programmable Logic Devices Replacement Considerations

Public datasheets recommend the ispLSI 2032VE-300 series for new designs due to higher performance. For direct functional substitution, verify compatibility with other speed grades within the 2032VE family or consider modern low-power FPGA alternatives from Lattice such as the MachXO or CrossLink series.
