ISPLSI-2032VL-110LT44

Overview

The ispLSI-2032VL-110LT44 is a Complex Programmable Logic Device (CPLD) from the Lattice ispLSI 2000VL family. It features 1000 PLD gates, 32 I/O pins, and two dedicated inputs within a 44-pin TQFP package. The device utilizes E2 CMOS technology for in-system programmability and non-volatile configuration. Key electrical specifications include a maximum operating frequency of 110 MHz and a propagation delay of 5.0 ns. It operates with a single 3.3V supply voltage.

Feature Summary

• In-System Programmability via IEEE 1149.1 JTAG interface
• Non-volatile Flash-based architecture retaining configuration without power
• High-density logic with 1000 PLD gates and 32 registers
• Global Routing Pool (GRP) for predictable timing and routing

Applications

• Address decoding and bus bridging in embedded systems
• State machine implementation for industrial control
• Logic replacement for legacy GAL/PLD designs
• Interface adaptation between different voltage domains

Procurement Notes

Verify component authenticity through authorized distributors due to the prevalence of counterfeits in legacy CPLD markets. Confirm manufacturing date codes as this part may be end-of-life or produced under obsolescence notices. Ensure storage conditions comply with moisture sensitivity level requirements prior to reflow soldering.

Selection Notes

Select this model when a non-volatile CPLD with 32 I/Os and 110 MHz performance is required. Compare against the ispLSI 2032VE series if lower cost is prioritized over the enhanced speed grade. Ensure the design fits within the 1000 PLD gate limit and utilizes the available macrocell resources efficiently.

Part Context

This component belongs to the ispLSI 2000VL family, which succeeded the original ispLSI 2000E/V series. It offers improved density and speed grades compared to earlier generations while maintaining pin-to-pin compatibility with many legacy PLD footprints. The VL suffix denotes a specific speed grade variant within the broader 2032 device line.

Replacement Considerations

Direct pin-compatible replacements include other variants in the ispLSI 2032 family such as the -180 or -225 speed grades, provided timing constraints are met. Cross-family migration to ispMACH 4000 devices requires schematic redesign due to architectural differences.
