ISPLSI 2128VE-135LB208

Complex Programmable Logic Devices Overview

The ispLSI 2128VE-135LB208 is a high-density, in-system programmable logic device manufactured by Lattice Semiconductor. It features 6000 PLD gates, 128 macrocells, and 28 I/O pins within a 208-ball fine-pitch ball grid array (fpBGA) package. Operating at a supply voltage of 3.3V, the device supports a maximum frequency of 135 MHz with a typical propagation delay of 7.5 ns. The architecture includes 32 Generic Logic Blocks (GLBs), three dedicated clock inputs, and eight dedicated input pins. It utilizes non-volatile EEPROM technology for reprogrammability and is fully IEEE 1149.1 boundary scan testable.

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix '135' corresponds to the required 135 MHz performance specification. Confirm the 'LB208' suffix matches the 208-ball fpBGA package requirement. Ensure design tools support the ispLSI 2128VE family for programming and verification.

Complex Programmable Logic Devices Selection Notes

Select this component when 128 macrocells and 28 I/Os are sufficient for the design logic density. The 135 speed grade is appropriate for applications requiring up to 135 MHz operation. Consider the fpBGA package constraints for PCB layout if higher pin counts or different form factors are needed.

Complex Programmable Logic Devices Part Context

This part belongs to the ispLSI 2128VE series, which offers 3.3V low-voltage operation while maintaining compatibility with standard 5V TTL devices. The VE series provides enhanced performance over previous V versions, featuring improved speed and power efficiency through E2CMOS technology.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 2128VE is functionally and pinout compatible with the older ispLSI 2128V series. Designers migrating from the V series can typically use the VE version as a drop-in replacement without schematic changes.
