LFEC1E-5TN100C

The LFEC1E-5TN100C is a commercial-grade Field Programmable Gate Array (FPGA) from Lattice Semiconductor’s LatticeEC family. It provides a compact, low-voltage programmable logic solution targeted at mainstream and cost-sensitive embedded designs that require flexible I/O and on-chip memory.

Built around approximately 1,500 logic elements and roughly 18 Kbits of on-chip RAM, this device is suited for control, interface bridging and memory-interfacing roles where modest logic density, a 67-pin I/O complement and a 100-pin package are required.

Key Features

• Logic Capacity — Approximately 1,500 logic elements for implementing glue logic, protocol bridging and custom control functions.
• On-chip Memory — Total RAM of 18,432 bits (approximately 18 Kbits) to support small buffers, state machines and register storage without external RAM.
• I/O Resources — 67 general-purpose I/Os suitable for interfacing sensors, peripherals and external memory interfaces.
• Power — Low-voltage supply range from 1.14 V to 1.26 V to match modern low-voltage system domains.
• Package Options — 100-pin LQFP package; supplier device package listed as 100-TQFP (14 × 14 mm) for compact board integration.
• Temperature and Grade — Commercial grade with an operating temperature range of 0 °C to 85 °C.
• Standards & Compliance — RoHS compliant for regulatory and environmental requirements.
• Family-level System Support — As part of the LatticeECP/EC family, supports mainstream FPGA features including flexible I/O buffers and clocking resources described in the family datasheet.

Typical Applications

• Embedded Control — Implement control logic, state machines and interface glue in compact consumer and industrial equipment.
• Sensor and Peripheral Interfaces — Aggregate and translate signals between sensors, ADCs/DACs and microcontrollers using available I/Os and on-chip logic.
• Memory Interface / Buffering — Small buffering and protocol handling for external memory or peripheral interfaces leveraging on-chip RAM.
• Low‑Power Portable Devices — Low-voltage operation enables integration in power-conscious designs requiring programmable logic.

Unique Advantages

• Compact, High‑value Package: 100-pin LQFP/TQFP packaging provides a small footprint option for space-constrained PCBs while maintaining a balanced I/O count.
• Low-voltage Operation: Designed for 1.14–1.26 V supply domains to simplify integration with modern low-voltage systems.
• Right-sized Logic and Memory: Approximately 1,500 logic elements and ~18 Kbits of RAM deliver a cost-effective balance of resources for mainstream embedded functions.
• Commercial Temperature Range: Rated for 0 °C to 85 °C, appropriate for a wide range of consumer and commercial applications.
• Regulatory Compliance: RoHS compliance eases environmental and supply-chain requirements.
• Family Ecosystem: Benefit from the LatticeECP/EC family features and design tools referenced in the datasheet for streamlined development and migration within the family.
