ISPLSI 1032E-70LTI

Complex Programmable Logic Devices Overview

The ispLSI 1032E-70LTI is an industrial-grade, high-density Complex Programmable Logic Device (CPLD) from Lattice Semiconductor. It features 6000 PLD gates, 64 universal I/O pins, eight dedicated inputs, and four dedicated clock inputs within a 100-pin TQFP package. Built on E2CMOS technology, it supports in-system programming via ISP with a maximum operating frequency of 70 MHz and a typical propagation delay of 15 ns. The device includes 192 registers, a Global Routing Pool for interconnectivity, and operates at 5V with non-volatile EEPROM storage.

Complex Programmable Logic Devices Feature Summary

• High Density Logic: Contains 6000 PLD gates, 32 Generic Logic Blocks (GLBs), and 192 registers.
• In-System Programmability: Supports 5V-only ISP via JTAG or serial interface for reprogramming soldered devices.
• Global Interconnect: Features a Global Routing Pool (GRP) and Output Routing Pool (ORP) for flexible signal routing.
• Clock Management: Includes four dedicated clock input pins (Y0-Y3) and a Clock Distribution Network.

Complex Programmable Logic Devices Applications

• Glue logic replacement in digital systems
• Address decoding and bus bridging
• State machine implementation
• Fast counter applications

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'LT' confirms the 100-pin TQFP package and industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status as lead-free options exist with different suffixes (e.g., LTNI). Check current product lifecycle status as older CPLD families may be discontinued or subject to PCNs.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 64 I/Os and 6000 system gates with 5V tolerance. Ensure timing requirements align with the 15 ns max propagation delay. For new designs, consider the functional superset ispLSI 1032EA series which offers enhanced features.

Complex Programmable Logic Devices Part Context

This component belongs to the ispLSI 1032E family, a high-density PLD line using E2CMOS technology. It serves as a functional superset to the earlier ispLSI 1032 architecture, adding global output enable pins while maintaining upward compatibility with JEDEC files.

Complex Programmable Logic Devices Replacement Considerations

For direct pin-to-pin and functional replacements within the same speed grade, consider the commercial grade variant ispLSI 1032E-70LJ. For newer designs, the ispLSI 1032EA series is recommended as a functional superset.
