ISPLSI 5384VE-165LB272

Complex Programmable Logic Devices Overview

The ispLSI 5384VE-165LB272 is a high-density, in-system programmable logic device from the Lattice ispLSI 5000VE family. It features 384 macrocells and approximately 18,000 PLD gates within an enhanced SuperWIDE architecture. The device operates on a 3.3V supply with user-selectable 3.3V or 2.5V I/O levels. Key electrical specifications include a maximum operating frequency of 165 MHz and a propagation delay as low as 6.0 ns. It supports up to 192 I/O pins and includes 384 registers with multiple control options. The component utilizes E2CMOS technology for non-volatile, electrically erasable reprogramming via IEEE 1149.1 Boundary Scan.

Complex Programmable Logic Devices Procurement Notes

Verify the specific speed grade suffix (-165) matches the required timing constraints of 165 MHz max frequency. Confirm the LB272 package designation corresponds to the 272-ball BGA footprint. Ensure design tools support the ispLSI 5000VE family, noting potential compatibility differences with the older 5000VA series.

Complex Programmable Logic Devices Selection Notes

Select this model when 384 macrocells and 192 I/Os are required in a compact BGA package. Compare against ispLSI 5384VA if JEDEC compatibility or specific preset functions are needed, as the VE family simplifies product term reset logic. Verify power consumption estimates based on the number of active product terms and clock frequency using the provided ICC equations.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 5000VE family, which enhances the previous 5000VA generation by optimizing macrocells and removing T-type flip-flop options. It shares pinouts with other family members like the ispLSI 5256VE and ispLSI 5512VE but offers distinct resource counts. The VE series focuses on efficient pin-locking and reduced complexity in control logic.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 5384VA is a related part but is not JEDEC compatible due to architectural differences in the macrocell and reset logic. Direct pin-for-pin replacement requires verification of timing and functionality, as pinouts may differ slightly between VA and VE versions in the same package.
