Key Features

• Logic Capacity  Approximately 1,500 logic elements and 192 logic blocks, suitable for mid-density embedded logic and glue-logic tasks.
• On‑Chip Memory  Total RAM bits: 18,432 (approximately 18 Kbits) of embedded memory for small data buffering and state storage.
• I/O Count & Flexibility  112 I/Os in the 208-BFQFP package; the family supports a wide range of I/O standards including LVCMOS, LVTTL, SSTL, HSTL, PCI, LVDS and others as documented for LatticeECP/EC devices.
• Clocking  Includes on-chip PLLs as provided in the LatticeECP/EC family (device table indicates two PLLs for LFEC1-class devices) for clock multiplication, division and phase control.
• Dedicated Memory Interface  Family-level support for dedicated DDR memory interfaces (up to DDR400 / 200 MHz) is provided in the LatticeECP/EC architecture.
• Power Supply  Operates from a low-voltage core supply range of 1.14 V to 1.26 V, compatible with 1.2 V system rails.
• Package & Mounting  208-BFQFP (supplier device package: 208-PQFP, 28 × 28 mm) surface-mount package for compact PCB implementation.
• Commercial Grade  Rated for commercial temperature range: 0 °C to 85 °C.
• Standards & Tools  Family-level features include IEEE 1149.1 boundary scan and support via Lattice ispLEVER design tools and ispLeverCORE IP modules for streamlined design integration.
• RoHS Compliant  Manufactured to meet RoHS requirements.

Typical Applications

• Embedded Control & Glue Logic  Mid-density logic and I/O consolidation for controller bridges, protocol translation and system glue where compact packaging and moderate logic/RAM are required.
• Memory Interface & Buffering  Implement DDR interface logic and intermediate buffering leveraging the family’s dedicated DDR support and on-chip RAM.
• Consumer & Industrial Electronics  User interface control, peripheral aggregation and custom timing/logic functions in commercial-temperature devices.
• Data Path & Pre‑Processing  Small-scale packet handling, signal conditioning and preprocessing tasks that benefit from programmable logic and flexible I/O.

Unique Advantages

• Right‑Sized Density:  1,500 logic elements and 192 logic blocks provide a balanced mid-range capacity for designs that need more than simple CPLDs but do not require large FPGAs.
• Flexible I/O Support:  112 I/Os and a family-level programmable sysI/O buffer support a broad set of interface standards, reducing the need for external level translators.
• Compact, Surface‑Mount Package:  208-BFQFP (28 × 28 mm) offers a compact footprint for space-constrained PCBs while keeping high I/O count accessible.
• Low‑Voltage Core:  Operates around 1.2 V (1.14–1.26 V range), aligning with modern low-voltage system rails for efficient power integration.
• Design Flow & IP Support:  Backed by Lattice ispLEVER tools and ispLeverCORE IP modules to accelerate implementation and reduce design time.
• Commercial Temperature & RoHS Compliance:  Suitable for commercial applications and manufactured to RoHS standards for regulatory compliance.
