ISPLSI 2032E-225LJ44

Complex Programmable Logic Devices Overview

The ispLSI 2032E-225LJ44 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, two dedicated inputs, and three dedicated clock inputs within a 44-pin PLCC package. Built on E2CMOS technology, the device supports a maximum operating frequency of 225 MHz with a propagation delay of 3.5 ns. It operates at 5V for the logic core and offers user-selectable 3.3V or 5V I/O levels only in 48-pin packages; the 44-pin variant is strictly 5V compatible.

Complex Programmable Logic Devices Feature Summary

• High-performance E2CMOS technology enabling 225 MHz operation and 3.5 ns propagation delay
• In-system programmability via IEEE 1149.1 JTAG interface for non-volatile reconfiguration
• Architecture includes eight Generic Logic Blocks (GLBs), 32 registers, and a Global Routing Pool
• Programmable output slew rate control to minimize switching noise

Complex Programmable Logic Devices Applications

• Glue logic replacement in digital systems
• Address decoding and state machine implementation
• Fast counter designs utilizing wide input gating
• Prototyping and field-upgradable logic circuits

Complex Programmable Logic Devices Procurement Notes

Verify that the specific application environment maintains a supply voltage between 4.75V and 5.25V, as the 44-pin PLCC package does not support 3.3V I/O operation. Confirm that the design toolchain supports the legacy ispLSI family for programming and configuration. Ensure compliance with the specified commercial temperature range of 0°C to +70°C for reliable operation.

Complex Programmable Logic Devices Selection Notes

Select this component when a 225 MHz speed grade is required for 1000-gate density logic. The 44-pin PLCC package is suitable for applications where 5V TTL compatibility is mandatory. For designs requiring mixed 3.3V/5V I/O environments, consider the 48-pin TQFP variant instead. Verify that the available 32 I/O pins and three dedicated clock inputs meet the system connectivity requirements.

Complex Programmable Logic Devices Part Context

This device belongs to the ispLSI 2032E series, which serves as an enhanced version of the earlier ispLSI 2032 family. It maintains 100% functional and JEDEC upward compatibility with previous generations while offering improved performance metrics. The -225 suffix specifically denotes the highest speed bin within this product line, optimized for high-frequency synchronous logic applications.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements include other speed grades within the same package, such as the ispLSI 2032E-200LJ44 or ispLSI 2032E-180LJ44. Cross-family upgrades may require schematic modifications due to architectural differences in newer Lattice CPLD families.
