LFE2-12E-5TN144C

The LFE2-12E-5TN144C is an ECP2 family Field Programmable Gate Array from Lattice Semiconductor Corporation, offered in a 144-LQFP package for surface-mount applications. It provides up to 12,000 logic elements and approximately 226,304 bits of on-chip RAM, along with 93 general-purpose I/Os, making it suitable for commercial designs that require moderate programmable logic capacity and flexible I/O connectivity.

Designed for operation within a 1.14 V to 1.26 V core supply range and a 0 °C to 85 °C temperature window, this device is presented in a compact 144-pin package for board-level integration where space and pin count are considerations.

Key Features

• Programmable Logic: Up to 12,000 logic elements to implement custom digital functions and control logic within a single device.
• Embedded Memory: Approximately 0.226 Mbits (226,304 bits) of on-chip RAM for buffering, state storage, and small data structures.
• I/O Capability: 93 user I/O pins suitable for interfacing with peripherals, sensors, and external logic.
• Power Supply Range: Core voltage specified from 1.14 V to 1.26 V to match system power architectures that support this supply window.
• Package & Mounting: 144-LQFP package (supplier device package listed as 144-TQFP, 20×20) designed for surface-mount assembly on standard PCBs.
• Commercial Grade Temperature: Rated for operation from 0 °C to 85 °C, appropriate for general commercial electronics environments.
• Regulatory Compliance: RoHS compliant for reduced hazardous substance content in manufactured assemblies.

Typical Applications

• Embedded Control and Logic: Implement glue logic, state machines, and custom control functions using the device’s 12,000 logic elements and on-chip RAM.
• Interface Bridging: Use the 93 I/Os to bridge or translate between multiple peripheral interfaces in compact, board-level systems.
• Prototyping and Development: Deploy in commercial product development where a reprogrammable logic element with moderate memory and I/O is required for iterative design.

Unique Advantages

• Balanced Logic and Memory: The combination of 12,000 logic elements and 226,304 bits of RAM supports a wide range of mid-complexity designs without external memory for many control and buffering tasks.
• Compact, Board-Ready Package: 144-LQFP footprint enables high-density PCB integration while maintaining accessible I/O counts for system connections.
• Commercial Temperature Rating: Specified 0 °C to 85 °C operation aligns with common commercial product requirements and deployment scenarios.
• Narrow Core Voltage Window: Defined 1.14 V to 1.26 V supply simplifies power rail planning for designs targeting this core voltage range.
• RoHS Compliant: Meets common environmental requirements for consumer and commercial electronics assemblies.
