ISPLSI2096-100LT

Overview

The ISPLSI2096-100LT is a Complex Programmable Logic Device (CPLD) from the Lattice ispLSI 2000A family, manufactured by Lattice Semiconductor. It features 96 macrocells and 4000 usable gates within a 128-pin Thin Quad Flat Package (TQFP). The device supports in-system programmability via JTAG and operates on a single 5V supply voltage with a range of 4.75 V to 5.25 V. It provides a maximum clock frequency of 77 MHz and offers a typical propagation delay of 10 ns. The component includes three dedicated inputs and 96 I/O lines, supporting both 3.3V and 5V I/O configurations.

Feature Summary

• Contains 96 macrocells and 24 logic blocks for complex logic implementation.
• Supports In-System Programming (ISP) using IEEE 1149.1 JTAG interface.
• Operates at a maximum frequency of 77 MHz with 10 ns typical delay.
• Features configurable I/O compatible with 3.3V and 5V logic levels.

Applications

• Protocol conversion between different voltage domains or standards.
• Address decoding and bus bridging in embedded systems.
• State machine implementation for industrial control applications.
• Replacement for legacy GAL devices in existing hardware designs.

Procurement Notes

Verify the specific suffix 'LT' against the manufacturer's current datasheet to confirm package type and lead-free status. Ensure the ordering code matches the required speed grade (-100) and that the component is sourced from authorized distributors to avoid counterfeit parts. Check for RoHS compliance if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a design requires moderate logic density with high pin count in a surface-mount package. Compare against the ISPLSI2096A series for updated manufacturing processes and lead-free options. Consider the ISPLSI2096E series if enhanced I/O flexibility or different packaging is required. Verify power consumption requirements against the 5V operation profile.

Part Context

This part belongs to the Lattice ispLSI 2000A family, which succeeded the original ispLSI 2000 series. The family is characterized by high-density PLDs utilizing fast EEPROM technology. The -100 suffix denotes a 10 ns speed grade, while the LT suffix typically indicates a TQFP package variant. This generation allows for reprogramming without removing the chip from the circuit board.

Replacement Considerations

Direct replacements include the ISPLSI2096A-100LTN128 for lead-free versions or the ISPLSI2096E-135LQ128 for QFP packages. Verify pin compatibility and electrical characteristics before substitution. Cross-reference with the manufacturer's obsolescence notices to ensure long-term availability.
