ISPLSI2128VL-150LB100

Overview

The ispLSI2128VL-150LB100 is a Complex Programmable Logic Device (CPLD) from the Lattice ispLSI 2000VE family. It features 128 macrocells, 6000 usable gates, and 32 Logic Array Blocks (LABs). The device provides 48 I/O pins and operates at a maximum frequency of 150 MHz with a typical propagation delay of 4 ns. It utilizes EEPROM technology for non-volatile configuration and supports In-System Programming (ISP). The component is housed in a 100-pin LBGA package and functions within a supply voltage range of 3.0 V to 3.6 V.

Feature Summary

• High-density architecture with 128 macrocells and 6000 gates across 32 LABs
• EEPROM-based non-volatile memory allowing instant-on operation
• Supports In-System Programming (ISP) via JTAG interface
• Maximum operating frequency of 150 MHz with 4 ns propagation delay

Applications

• High-speed data bus bridging and protocol conversion
• Address decoding and memory interface control
• Complex glue logic replacement in industrial systems
• FPGA configuration controllers and boot logic

Procurement Notes

Verify the specific suffix 'VL' against official Lattice documentation to confirm the temperature grade and speed bin. Confirm the 'LB100' designation corresponds to the Leadless Ball Grid Array package type. Check current product lifecycle status as older CPLD families may be discontinued or subject to long lead times.

Selection Notes

Select this model when a high-speed CPLD with 128 macrocells is required. Ensure the design fits within the 48 I/O limit and 6000 gate capacity. Verify that the system requires non-vatile storage to eliminate external configuration flash memory. Compare performance metrics against the standard ispLSI 2128V if lower speed requirements allow for cost reduction.

Part Context

This part belongs to the ispLSI 2000VE series, an evolution of Lattice's popular ispLSI 2000 line. The VE series offers improved performance and density over previous generations while maintaining pin-compatible options. It serves as a bridge between low-end PLDs and high-end FPGAs, offering deterministic timing and ease of use.

Replacement Considerations

Direct replacements include other variants within the ispLSI 2128 family with different speed grades or packages. Cross-family migration to the ispMACH 4000 or ispMACH 5000 series may require schematic and code adjustments due to architectural differences.
