ISPLSI 1032E-70LJN

Complex Programmable Logic Devices Overview

The ispLSI 1032E-70LJN is a high-density, in-system programmable logic device (PLD) manufactured by Lattice Semiconductor. It utilizes E2CMOS technology to provide non-volatile configuration with 6000 PLD gates, 192 registers, and 64 universal I/O pins. The -70 speed grade supports a maximum operating frequency of 70 MHz with a typical propagation delay of 15 ns. Designed for 5V operation, it features four dedicated clock inputs and a global routing pool for flexible interconnectivity. The component is housed in an 84-pin lead-free PLCC package.

Complex Programmable Logic Devices Procurement Notes

Verify that the specific ordering suffix 'LJN' corresponds to the lead-free 84-pin PLCC package variant as defined in the official Lattice Semiconductor datasheet. Confirm industrial temperature range availability if required, noting that 'LJI' denotes the industrial version while 'LJN' typically indicates commercial grade lead-free packaging. Ensure design compatibility with the recommended ispLSI 1032EA series for new developments.

Complex Programmable Logic Devices Selection Notes

Select the ispLSI 1032E-70LJN when a non-volatile CPLD solution with approximately 6000 gates is required. This model is suitable for applications needing 64 I/Os and 192 registers. Compare against the -100 or -125 speed grades if higher frequencies are necessary, or consider the ispLSI 1032EA family for updated design recommendations. Ensure power supply constraints align with the 5V nominal requirement.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 1032E family of high-density PLDs. It serves as a functional superset of the earlier ispLSI 1032 architecture, adding two global output enable pins. The device bridges the gap between traditional PLDs and FPGAs, offering the ease of use of PLDs with the density of FPGA-like structures. It is designed for systems requiring reconfigurable logic with retained state after power loss.

Complex Programmable Logic Devices Replacement Considerations

For new designs, Lattice recommends using the ispLSI 1032EA series. Direct pin-compatible replacements within the same speed grade include the standard plastic packaged versions (e.g., ispLSI 1032E-70LJ). Verify package dimensions and moisture sensitivity levels when substituting lead-free variants for standard packages.
