LFE2-12E-5T144C

Field Programmable Gate Array Overview

The LFE2-12E-5T144C is a Field Programmable Gate Array (FPGA) belonging to the LatticeECP2/M family manufactured by Lattice Semiconductor. This device features 12,000 Logic Update Modules (LUMs), which equate to approximately 12k Look-Up Tables (LUTs). It supports a maximum operating speed grade of -5 and utilizes a 1.2V core voltage supply. The component is housed in a 144-pin Thin Quad Flat Package (TQFP) with a 0.5mm pitch. It includes 93 general-purpose I/O pins and integrates embedded DSP blocks for signal processing applications.

Field Programmable Gate Array Feature Summary

• Low-power architecture optimized for energy efficiency in portable and battery-operated systems
• Embedded Digital Signal Processing (DSP) blocks for high-performance arithmetic operations
• Non-volatile configuration memory enabling instant-on functionality without external boot devices
• Support for multiple I/O standards and voltage levels through configurable banks

Field Programmable Gate Array Applications

• Industrial automation and control systems requiring low power consumption
• Consumer electronics and IoT devices needing compact form factors
• Signal processing interfaces and protocol conversion bridges
• Test and measurement equipment requiring flexible logic implementation

Field Programmable Gate Array Procurement Notes

Verify the specific suffix codes against the official LatticeECP2/M datasheet DS1006 to confirm temperature range and package type. Ensure design compatibility with the 1.2V core voltage requirement. Confirm that the TQFP-144 package dimensions meet PCB layout constraints. Cross-reference the -5 speed grade with system timing requirements before finalizing procurement.

Field Programmable Gate Array Selection Notes

Select this model when a balance of moderate logic density and ultra-low power consumption is required. The ECP2/M family is suitable for designs needing embedded DSP capabilities without the complexity of higher-density FPGAs. Consider the non-volatile configuration feature if board space for external flash memory is limited. Evaluate the -5 speed grade against clock frequency requirements to ensure adequate timing margins.

Field Programmable Gate Array Part Context

This component is part of the LatticeECP2/M family, designed as a low-power FPGA solution. It sits between the smaller MachXO series and the larger ECP3/ECP5 families in terms of logic capacity. The family is known for its robust security features and support for mixed-signal applications. It targets markets where power efficiency and small physical footprint are critical design drivers.

Field Programmable Gate Array Replacement Considerations

Direct replacements within the same family include other LFE2 variants with different speed grades or package options, such as LFE2-12E-6T144C. For pin-compatible upgrades, consider LFE2-12E-5FN256C if a BGA package is acceptable. Verify that any substitute maintains the 1.2V core voltage and compatible I/O configurations.
