ISPLSI 2128VE-180LB208

Complex Programmable Logic Devices Overview

The ispLSI 2128VE-180LB208 is a high-density, in-system programmable logic device from Lattice Semiconductor. It features 6000 PLD gates, 128 registers, and 128 I/O pins housed in a 208-ball fpBGA package. The device utilizes E2CMOS technology with a maximum operating frequency of 250 MHz and a propagation delay of 4.0 ns. It operates at 3.3V, supports IEEE 1149.1 boundary scan testing, and offers non-volatile reprogrammability via the Boundary Scan TAP.

Complex Programmable Logic Devices Feature Summary

• High-performance SuperFAST architecture with 250 MHz fmax and 4.0 ns tpd
• In-system programmability (ISP) using IEEE 1149.1 Boundary Scan Test Access Port
• 3.3V low voltage operation compatible with standard 5V TTL devices
• Programmable open-drain outputs for flexible bus interface and wired-OR arbitration

Complex Programmable Logic Devices Applications

• Complex digital logic replacement
• Address decoding and state machine implementation
• System interconnect and protocol bridging
• Industrial control systems requiring in-field reconfiguration

Complex Programmable Logic Devices Procurement Notes

Verify that the specific ordering suffix LB208 corresponds to the 208-ball fpBGA package variant. Confirm the -180 speed grade matches the required timing constraints for the target design. Ensure compatibility with Lattice Diamond or Radiant software tools for programming and configuration.

Complex Programmable Logic Devices Selection Notes

Select this device when designs require high pin counts (128 I/Os) and moderate logic density (6000 gates). The -180 speed grade provides a balance between performance and power consumption. Consider the fpBGA package for space-constrained applications requiring robust solder joint reliability.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 2128VE family, which is electrically and pinout compatible with the older ispLSI 2128V series. It serves as a drop-in replacement for legacy designs while offering enhanced in-system programmability and lower voltage operation capabilities.

Complex Programmable Logic Devices Replacement Considerations

Direct functional replacements include other variants within the ispLSI 2128VE family, such as the -250 speed grade for higher performance requirements. Legacy equivalents like the ispLSI 2128V are compatible but lack ISP features.
