ISPLSI-3160-100LQI

Overview

The ispLSI-3160-100LQI is a high-density Complex Programmable Logic Device (CPLD) from the Lattice ispLSI 3000 family. It features 256 macrocells and supports up to 48 I/O pins within a 240-pin PQFP package. The device operates at a maximum frequency of 100 MHz with a typical propagation delay of 10 ns. It utilizes non-volatile EEPROM technology for configuration, allowing in-system programmability via JTAG. The component is designed for commercial temperature ranges and requires a 5V supply voltage.

Feature Summary

• 256 Macrocells with 48 I/Os in a 240-pin PQFP package
• 100 MHz operating speed with 10 ns propagation delay
• Non-volatile EEPROM memory for instant-on capability
• In-System Programmability (ISP) support

Applications

• High-speed interface bridging
• Address/data bus buffering
• State machine implementation
• Protocol conversion logic

Procurement Notes

Verify the specific suffix 'LQI' against official Lattice documentation to confirm the exact temperature grade and moisture sensitivity level, as suffixes define environmental ratings. Confirm end-of-life status through authorized distributors, as this series may be discontinued or superseded by newer families like ispMACH 4000V.

Selection Notes

Select this component when a design requires moderate density (256 macrocells) with high pin count in a quad flat package. Ensure the system accommodates the 5V power requirement and that the 10 ns delay meets timing constraints. Compare against the ispLSI 3256 if higher density is needed or the ispLSI 3128 if fewer resources suffice.

Part Context

This part belongs to the ispLSI 3000 family, which introduced non-volatile CPLD technology to the market. It bridges the gap between low-density GALs and high-density FPGAs, offering reprogrammability without the volatility of SRAM-based devices. It succeeded earlier ispLSI 2000 series parts with improved performance and density.

Replacement Considerations

Direct pin-to-pin replacements are limited due to architectural differences. Consider the ispLSI 3256 for increased macrocells or the ispMACH 4000V family for lower power consumption and faster speeds, though package and voltage requirements must be validated.
