ISPLSI 2032E-110LJ44

Complex Programmable Logic Devices Overview

The ispLSI 2032E-110LJ44 is a high-density, in-system programmable complex programmable logic device (CPLD) manufactured by Lattice Semiconductor. It features 1000 PLD gates, 32 universal I/O pins, and two dedicated inputs within a 44-pin PLCC package. Built on E2CMOS technology, the device supports a maximum operating frequency of 110 MHz with a typical propagation delay of 10.0 ns. It includes 32 registers, three dedicated clock input pins, and a Global Routing Pool for complete interconnectivity. The core operates at 5V, while I/O levels are TTL compatible.

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix '110' corresponds to the required 110 MHz performance. Confirm the 'J44' suffix indicates the 44-pin PLCC package. Check current product status as older ispLSI families may have discontinuation notices from the manufacturer.

Complex Programmable Logic Devices Selection Notes

Select this part for designs requiring moderate density with low pin counts. Ensure the design fits within the 1000 gate limit and 32 register capacity. Verify that the 5V logic core voltage aligns with the system power supply requirements.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 2000E family, which offers upward compatibility with the earlier ispLSI 2000 series. The -110 variant provides a balance between speed and power consumption compared to the faster -225 models. It utilizes EEPROM technology for non-volatile storage of configuration data.

Complex Programmable Logic Devices Replacement Considerations

For new designs, Lattice recommends using the ispLSI 2032E-225 series. Functionally equivalent parts include other variants in the ispLSI 2032E family with different speed grades or packages, provided the timing constraints are met.
