ISPLSI81080V-90LB272

Overview

The ISPLSI81080V-90LB272 is a Complex Programmable Logic Device (CPLD) belonging to the ispLSI 8000 family, manufactured by Lattice Semiconductor. It features 8 macrocells and supports up to 80 I/O pins within a 272-ball Ball Grid Array (BGA) package. The device utilizes E² CMOS technology, offering non-volatile configuration with propagation delays of 9.0 ns. It operates on a single 3.3V supply voltage and supports in-system programming via JTAG.

Feature Summary

• ispLSI 8000 series CPLD architecture with 8 macrocells
• Up to 80 user I/O pins available
• Non-volatile E² CMOS technology for instant-on operation
• In-system programmability via IEEE 1149.1 JTAG interface

Applications

• Address decoding and bus bridging
• Glue logic replacement
• State machine implementation
• Interface translation between different voltage domains

Procurement Notes

Verify the specific suffix 'LB272' against the manufacturer's official datasheet to confirm the exact pinout and package dimensions. Confirm that the 'V' speed grade corresponds to the required 9.0 ns timing specifications for your design constraints before procurement.

Selection Notes

Select this component when a small number of macrocells is sufficient but a high pin count is required. Ensure the PCB layout accommodates the 272-ball BGA footprint. Verify that the system power budget aligns with the static and dynamic current consumption characteristics of the E² CMOS core at 3.3V.

Part Context

This part is part of the ispLSI 8000 family, which succeeded the ispLSI 5000 series. It provides higher density and performance while maintaining upward compatibility with earlier JEDEC standards. The family is designed for applications requiring non-volatile logic with flexible I/O capabilities.

Replacement Considerations

Check for direct functional equivalents within the ispLSI 8000 family with compatible pinouts. Consider newer Lattice FPGA families if additional logic resources or advanced interfaces are needed, though pin-to-pin replacements may not be available for all legacy packages.
