ISPLSI-3160-125LB272

Overview

The ISPLSI-3160-125LB272 is a high-density Complex Programmable Logic Device (CPLD) from the ispLSI 3000 family by Lattice Semiconductor. It features 16,384 usable macrocells and supports system-level programmability via In-System Programming (ISP). The device operates with a typical propagation delay of 12.5 ns and utilizes a 5V supply voltage for I/Os while maintaining low power consumption characteristics. It is housed in a 272-pin Low Profile Quad Flat Package (LQFP), providing extensive I/O capabilities suitable for complex digital logic applications requiring high density and flexibility.

Feature Summary

• High Density: Contains 16,384 usable macrocells for complex logic implementation.
• In-System Programmability: Supports ISP technology for field updates without removal from the board.
• Performance: Typical propagation delay of 12.5 ns ensures fast signal processing.
• Package: Available in a 272-pin LQFP package for high pin-count requirements.

Applications

• Complex glue logic replacement in industrial control systems.
• Address decoding and bus bridging in embedded computing architectures.
• State machine implementation for automated manufacturing equipment.
• Protocol conversion interfaces in telecommunications infrastructure.

Procurement Notes

Verify the specific suffix codes against official Lattice documentation to confirm temperature grade and package variant. Ensure compatibility with legacy programming tools if updating existing designs. Check for end-of-life status or obsolescence notices prior to procurement planning.

Selection Notes

Select this model when designs require over 10,000 macrocells and support for 5V I/O standards. Compare against the ispMACH 4000 series for lower density needs or newer FPGA families for higher performance requirements. Confirm that the 272-pin footprint fits the target PCB layout constraints.

Part Context

This component belongs to the ispLSI 3000 family, which was designed to bridge the gap between standard PLDs and FPGAs. It offers non-volatile configuration and high reliability, making it suitable for applications where code security and instant-on functionality are critical compared to volatile FPGA solutions.

Replacement Considerations

Direct pin-to-pin replacements may be limited due to the age of the product line. Consider migrating to the ispMACH 4000V/Z series for similar CPLD functionality with updated features. Verify logical equivalence and timing constraints when substituting with modern high-density PLDs.
