ISPLSI 2032A-180LT48

Complex Programmable Logic Devices Overview

The ispLSI 2032A-180LT48 is a high-density complex programmable logic device (CPLD) manufactured by Lattice Semiconductor. It utilizes advanced 0.35 micron E2CMOS technology to deliver a maximum operating frequency of 180 MHz and a propagation delay of 5.0 ns. The device features 1000 PLD gates, 32 macrocells, and 32 universal I/O pins within a 48-pin TQFP package. It supports non-volatile in-system programming via ISP at 5V, allowing for reprogramming of soldered devices. Key architectural elements include eight Generic Logic Blocks (GLBs), a Global Routing Pool (GRP), and three dedicated clock input pins.

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required package and temperature grade. Check for Product Change Notifications (PCN) regarding discontinuation status, as select devices in this family have been discontinued. Ensure design files are compatible with current programming tools.

Complex Programmable Logic Devices Selection Notes

Select the ispLSI 2032A-180LT48 when 1000 PLD gates and 32 I/Os are sufficient for the design. The -180 speed grade provides 180 MHz performance. Compare against the ispLSI 2032E series for new designs, as recommended by the manufacturer. Consider power consumption estimates based on product term usage and toggle frequency. Verify voltage compatibility with the 5V core requirement.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 2032/A family of high-density PLDs. It is functionally and form-compatible with the original ispLSI 2032 but built on an advanced 0.35 micron process. The LT48 suffix denotes a 48-pin Thin Quad Flat Package (TQFP). This family bridges the gap between simple PLDs and FPGAs, offering structured design flexibility.

Complex Programmable Logic Devices Replacement Considerations

The datasheet explicitly recommends using the ispLSI 2032E series for new designs. Direct pin-to-pin replacements within the same package may include other speed grades like ispLSI 2032A-150LT48, provided timing constraints allow.
