ISPLSI 5384VE-125LB272

Complex Programmable Logic Devices Overview

The ispLSI 5384VE is a second-generation SuperWIDE high-density in-system programmable logic device manufactured by Lattice Semiconductor. It utilizes E2CMOS technology to provide 18,000 PLD gates and 384 macrocells within a single chip. The device operates on a 3.3V power supply with user-selectable 3.3V or 2.5V I/O levels. Key electrical specifications include a maximum operating frequency (fmax) of 165 MHz and a propagation delay (tpd) as low as 6.0 ns. It features up to 192 I/O pins, 384 registers, and four dedicated clock input pins.

Complex Programmable Logic Devices Feature Summary

• SuperWIDE Architecture: Utilizes Generic Logic Blocks (GLBs) containing 32 registered macrocells each, interconnected via a Global Routing Pool for high-speed signal distribution.
• High Performance: Achieves fmax of 165 MHz and tpd of 6.0 ns using E2CMOS technology with programmable speed/power logic path optimization.
• Flexible I/O Configuration: Supports user-selectable 3.3V/2.5V I/O levels, allowing interfaces with standard 5V TTL devices while powered by 3.3V.
• In-System Programmability: Features non-volatile, electrically erasable/reprogrammable logic and interconnect structures accessible via IEEE 1149.1 Boundary Scan.

Complex Programmable Logic Devices Applications

• High-speed binary counters
• Complex state machines
• Address decoders

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix (e.g., -125LB272) against the manufacturer's current product status, as the ispLSI 5000VE family has undergone discontinuation notices. Confirm package availability, as BGA options may be limited. Ensure design tools support the specific architectural differences between the VE and VA families, as they are not JEDEC compatible.

Complex Programmable Logic Devices Selection Notes

Select this component when high density (384 macrocells) and fast global routing are required for complex logic designs. The VE architecture simplifies product term reset logic compared to the VA family but removes T-type flip-flop options and programmable output-delay skew. Verify that the 192 I/O pin count fits the board layout constraints of the 272-ball BGA package.

Complex Programmable Logic Devices Part Context

The ispLSI 5384VE belongs to the ispLSI 5000VE family, which ranges from 128 to 512 macrocells. It shares the same programming and power/ground pin locations as the earlier ispLSI 5000VA family but differs in internal architecture and pinouts for I/O signals. It is designed for applications requiring reconfigurable systems with high manufacturing yields and reduced time-to-market.

Complex Programmable Logic Devices Replacement Considerations

The ispLSI 5384VE is not JEDEC compatible with the ispLSI 5384VA due to architectural changes. Direct pin-for-pin replacement with other CPLD families requires careful verification of I/O mapping, voltage levels, and timing characteristics. Consult the manufacturer's Product Change Notification (PCN) for current lifecycle status.
