ISPLSI-3160-100LB272

Overview

The ispLSI-3160-100LB272 is a Complex Programmable Logic Device (CPLD) from the Lattice ispLSI 3000 family, manufactured by Lattice Semiconductor Corporation. It features a density of 16,000 system gates and utilizes an EEPROM-based non-volatile memory technology for configuration storage. The device operates with a supply voltage range of 4.5 V to 5.5 V and supports a maximum operating frequency of 100 MHz. It provides 272 I/O pins within a 272-pin Low Profile Ball Grid Array (LPGA) package. Key electrical parameters include a typical propagation delay of 10 ns and a maximum power consumption of 190 mA at 5 V.

Feature Summary

• EEPROM-based non-volatile configuration for instant-on operation
• Supports in-system programming via JTAG interface
• Operates at frequencies up to 100 MHz with 10 ns typical delay

Applications

• High-speed data acquisition systems
• Complex bus bridging and protocol conversion
• Industrial control logic and automation
• Test and measurement equipment interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm specific suffix codes match exact speed grades and package variants. Check for RoHS compliance status if required for modern manufacturing standards. Ensure proper ESD handling procedures are followed during procurement and storage.

Selection Notes

Select this model when high pin count and moderate speed are required for complex logic implementation. Compare against ispMACH 4000V series for lower power requirements or higher speeds. Consider the EEPROM technology benefits for non-volatile configurations versus volatile FPGA alternatives. Verify package compatibility with existing PCB footprints for the 272-pin LPGA form factor.

Part Context

This component belongs to the ispLSI 3000 family, representing a generation of high-performance CPLDs designed for applications requiring large logic capacity and flexible I/O configurations. It bridges the gap between smaller CPLDs and larger FPGAs, offering deterministic timing and non-volatile storage without the complexity of SRAM-based devices.

Replacement Considerations

Direct replacements may be limited due to the discontinued nature of the ispLSI 3000 family. Evaluate ispLSI 2000ZE or ispMACH 4000V/Z series for functional equivalents, noting differences in gate density, I/O counts, and power characteristics. Pin-to-pin compatibility should be verified before substitution.
