ISPLSI 5512VE-100LF256

Complex Programmable Logic Devices Overview

The ispLSI 5512VE-100LF256 is a high-density, in-system programmable logic device (PLD) from Lattice Semiconductor. It features 24,000 PLD gates and 512 macrocells organized into sixteen Generic Logic Blocks (GLBs). 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 155 MHz and a propagation delay as low as 6.5 ns. It utilizes E2CMOS technology for non-volatile configuration and supports IEEE 1149.1 boundary scan testing.

Complex Programmable Logic Devices Feature Summary

• High Density: Contains 512 macrocells and up to 256 I/O pins within a single package.
• In-System Programmability: Supports reprogramming via the IEEE 1149.1 JTAG interface without removing the device from the PCB.
• Flexible I/O: Features independent VCCIO control allowing mixed 3.3V and 2.5V voltage standards.
• Advanced Architecture: Utilizes SuperWIDE GLBs with a Global Routing Pool for optimized pin locking and fast interconnect.

Complex Programmable Logic Devices Applications

• Complex state machine implementations requiring high-speed global clocks.
• Address decoding and bus bridging in industrial control systems.
• Prototyping and development boards utilizing in-system reconfigurability.
• Interface adapters between legacy TTL devices and modern 3.3V/2.5V logic families.

Complex Programmable Logic Devices Procurement Notes

Verify that the specific suffix LF indicates lead-free compliance and RoHS adherence. Confirm the -100 speed grade matches the required timing constraints for your design. Ensure the 256-pin fpBGA package footprint aligns with your PCB layout specifications before ordering.

Complex Programmable Logic Devices Selection Notes

Select this model when designs require more than 256 macrocells but do not necessitate FPGA-level density. Consider the 5512VE over lower-density variants like the 5384VE if the design exceeds 384 macrocells. Verify that the 155 MHz performance meets the system clock requirements.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 5000VE family, which succeeded the ispLSI 5000VA series. While it shares similar programming interfaces, the 5000VE architecture features simplified product term reset logic and removed skew options, making it distinct from previous generations despite physical pin compatibility.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements are limited due to the proprietary nature of the E2CMOS technology. For equivalent gate counts, consider the ispLSI 5384VE or higher-density members of the same family. Cross-family migration to MachXO or ICE40 requires significant architectural redesign.
