ISPLSI1048E-70LQNI

The ISPLSI1048E-70LQNI from Lattice Semiconductor is a high-performance, non-volatile Complex Programmable Logic Device (CPLD) belonging to the ispLSI 1000E family. Fabricated in E²CMOS technology, it integrates 48 macrocells and offers in-system programmability via a standard IEEE 1149.1 JTAG interface, eliminating the need for external programming hardware. The “-70” speed grade designates a 7.5 ns pin-to-pin logic delay, providing deterministic timing characteristics for critical paths. Housed in a low-profile quad flat pack (LQFP), the device operates from a single 5 V supply and supports industrial temperature ranges (-40°C to +85°C) as confirmed by the “I” suffix, ensuring reliable functionality in thermally stressed environments.

Typical deployment scenarios include industrial automation equipment, military and aerospace subsystems, and communications infrastructure where a proven, moderate-density programmable logic solution is needed for glue logic consolidation, state machine control, address decoding, and I/O expansion. Procurement specialists should note that the ispLSI 1000E series has matured and may face obsolescence risks, making authorized distribution sourcing essential for obtaining factory-original devices and long-term supply continuity. The industrial-grade rating reinforces its suitability for high-reliability applications, though designs requiring extended temperature or stringent qualification standards should verify whether additional screening beyond the commercial/industrial baseline is required.
