LFE2-6SE-6T144I

The LFE2-6SE-6T144I is an ECP2 Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor Corporation. It delivers a mid-range logic capacity with 6,000 logic elements, 750 CLBs and 90 general-purpose I/O pins in a compact 144-pin LQFP package.

With a core supply range of 1.14 V to 1.26 V, industrial operating temperature range of –40 °C to 100 °C and RoHS compliance, this device is intended for industrial and embedded designs that require reconfigurable logic, on-chip memory and a small-footprint surface-mount package.

Key Features

• Core Logic 
  6,000 logic elements and 750 CLBs provide reconfigurable fabric for custom digital logic implementations.
• Embedded Memory 
  Approximately 56.3 Kbits (56,320 bits) of on-chip RAM to support buffers, FIFOs and small data storage needs.
• I/O Count 
  90 I/O pins enable connection to peripherals, sensors and external logic in dense designs.
• Power 
  Core voltage supply range from 1.14 V to 1.26 V to match low-voltage system domains.
• Package & Mounting 
  144-LQFP package case; supplier device package listed as 144-TQFP (20×20). Surface-mount mounting supports automated PCB assembly.
• Temperature & Grade 
  Industrial grade device with operating temperature range of –40 °C to 100 °C for extended environmental tolerance.
• Compliance 
  RoHS compliant to support regulatory requirements for lead-free assembly.

Typical Applications

• Industrial Control 
  Used for custom logic, protocol conversion and interface handling in industrial equipment where temperature range and reliability matter.
• Embedded Systems 
  Provides reconfigurable compute and I/O consolidation for compact embedded designs requiring on-chip RAM and multiple I/Os.
• Prototyping and Custom Logic 
  Ideal for development and deployment of application-specific digital functions where a mid-range logic element count is sufficient.

Unique Advantages

• Balanced Logic Capacity 
  6000 logic elements with 750 CLBs deliver a practical trade-off of resources for mid-complexity designs without excessive board area.
• Compact Package 
  144-pin LQFP (surface mount) minimizes PCB footprint while providing substantial I/O density (90 pins).
• Industrial Temperature Range 
  Rated from –40 °C to 100 °C to support deployment in harsher environmental conditions.
• Low-Voltage Core 
  1.14 V to 1.26 V supply range aligns with modern low-voltage system architectures.
• On-Board Memory 
  Approximately 56.3 Kbits of embedded RAM for buffering, small data tables and control-state storage.
• RoHS Compliance 
  Supports lead-free manufacturing and environmental regulatory requirements.
