LIFCL-33U-7CTG104C

The LIFCL-33U-7CTG104C is a field‑programmable gate array (FPGA) from Lattice Semiconductor, belonging to the CrossLink‑NX‑33/33U family. It provides a programmable fabric with 33,000 logic elements, embedded RAM, and a suite of on‑chip IP blocks documented in the CrossLink‑NX data sheet.

Designed for compact, low‑voltage systems, the device targets applications that require flexible programmable I/O, on‑chip DSP and memory resources, integrated peripherals such as USB, and a small BGA footprint. Key value comes from integrated resources in a compact 104‑CABGA (8×8) surface‑mount package.

Key Features

• Core FPGA Fabric — Approximately 33,000 logic elements for implementing custom logic, signal processing, and glue‑logic functions; part of the CrossLink‑NX‑33/33U series.
• Embedded Memory — 65,536 bits of total on‑chip RAM for buffering, LUTs, and small data stores.
• Programmable I/O — 72 I/O pins with programmable I/O cell architecture (PIO/PIC) for flexible interface options as described in the CrossLink‑NX documentation.
• On‑chip IP and Peripherals — Device family documentation includes sysDSP, global PLLs, on‑chip oscillator, USB hardware, and a cryptographic engine for designs that leverage integrated IP blocks.
• Power and Voltage — Core supply operating range of 0.95 V to 1.05 V to match modern low‑voltage power domains.
• Package and Mounting — 104‑CABGA (8×8) surface‑mount package for compact board designs with a higher‑density pinout.
• Commercial Grade — Rated for commercial operating temperatures from 0 °C to 85 °C.
• Test and Reliability — Documentation includes IEEE‑1149.1 boundary scan and SEU handling features referenced in the CrossLink‑NX data sheet.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Interface and protocol bridging — Implement custom protocol converters and interface logic using the programmable I/O and dense logic fabric.
• USB‑enabled embedded peripherals — Leverage the documented USB hardware and on‑chip resources for USB device or host functionality.
• On‑chip signal processing — Use sysDSP and embedded RAM for compact DSP tasks and local buffering in sensor or control systems.
• Space‑constrained systems — The 104‑CABGA (8×8) package and surface‑mount mounting suit compact PCBs that require moderate pin counts (72 I/Os).

Unique Advantages

• High logic capacity: 33,000 logic elements provide substantial implementation space for complex logic and state machines.
• Integrated memory: 65,536 bits of embedded RAM reduce external memory dependence for small buffering and lookup needs.
• Flexible interfacing: 72 programmable I/Os enable diverse peripheral connections and custom signaling.
• Low‑voltage core: 0.95–1.05 V supply range aligns with modern power architectures and allows straightforward integration into low‑power designs.
• Compact BGA footprint: 104‑CABGA (8×8) package balances board space and pin count for dense designs.
• Documented on‑chip IP: Family documentation covers PLLs, sysDSP, USB, cryptographic engine, and additional blocks to accelerate integration.
