ISPLSI 1032E-70LTN

Complex Programmable Logic Devices Overview

The ispLSI 1032E-70LTN is a high-density, in-system programmable complex programmable logic device (CPLD) manufactured by Lattice Semiconductor. It utilizes E2CMOS technology to provide non-volatile configuration with 6000 PLD gates and 192 registers. The device features 64 universal I/O pins and eight dedicated inputs within a 100-pin Thin Quad Flat Package (TQFP). Designed for industrial applications, it operates over a temperature range of -40°C to +85°C. Key electrical specifications include a maximum operating frequency of 70 MHz and a typical propagation delay of 15 ns.

Complex Programmable Logic Devices Feature Summary

• High-density architecture with 6000 PLD gates, 32 Generic Logic Blocks (GLBs), and 192 registers.
• In-System Programmability (ISP) allowing reconfiguration of soldered devices using only 5V power.
• Industrial temperature rating (-40°C to +85°C) with TTL-compatible I/O levels.
• Flexible clocking via four dedicated clock pins (Y0-Y3) and a programmable Clock GLB.

Complex Programmable Logic Devices Applications

• Complex glue logic replacement in industrial control systems
• Address decoding and state machine implementation
• Protocol conversion and interface bridging
• Fast counters and sequential logic design

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'TN' confirms the lead-free 100-pin TQFP package variant. Confirm that the 'I' suffix for industrial grade is present if operation below 0°C is required, as the base model may be commercial grade. Check moisture sensitivity level (MSL) requirements for the lead-free package during assembly handling.

Complex Programmable Logic Devices Selection Notes

Select this component when non-volatile reprogrammability and moderate density are required. The -70 speed grade offers a balance between performance (70 MHz fmax) and power consumption. Ensure the 100-pin TQFP footprint fits the board layout constraints compared to the 84-pin PLCC alternative.

Complex Programmable Logic Devices Part Context

This part belongs to the ispLSI 1032E family, which serves as an enhanced version of the original ispLSI 1032. The 'E' designation indicates added features such as two global output enable pins. The datasheet explicitly recommends using the ispLSI 1032EA series for new designs, positioning this part as a legacy or existing design component.
