LCMXO3LF-4300E-5UWG81CTR1K

The LCMXO3LF-4300E-5UWG81CTR1K is a MachXO3 family field programmable gate array (FPGA) device designed for compact, low-voltage system integration. Built on the MachXO3 architecture, this device combines programmable logic, embedded memory, and hardened system IP to support control, glue-logic, and peripheral interfacing in cost- and space-constrained commercial designs.

With 4,320 logic elements, approximately 94,208 bits of embedded RAM, and 63 user I/Os in an 81‑WLCSP package (3.80 × 3.69 mm), this part targets applications requiring a small footprint, non-volatile configuration, and flexible I/O and clocking options.

Key Features

• Logic Capacity  4,320 logic elements with 540 logic clusters provide the programmable fabric required for control, protocol bridging, and simple processing functions.
• Embedded Memory  Approximately 0.094 Mbits (94,208 bits) of on-chip RAM for FIFOs, buffers, and small data storage.
• I/O and Interfaces  63 user I/Os with support for MachXO3 family I/O features including pre‑engineered source synchronous I/O and flexible on‑chip buffer options as described in the MachXO3 family documentation.
• Non‑volatile Configuration  MachXO3 family features include non-volatile, multi-time programmable configuration and TransFR reconfiguration capabilities for in-system updates.
• Embedded Hardened IP  Family-level documentation lists hardened I2C and SPI IP cores, timer/counter functions, and other system IP to accelerate development of common peripheral interfaces.
• Clocking and Timing  Flexible on-chip clocking with system PLLs and internal oscillators (per MachXO3 family data sheet) to support a range of timing and synchronization schemes.
• Package and Mounting  Compact 81‑WLCSP package (3.80 × 3.69 mm) for minimal PCB area and surface-mount assembly.
• Power and Thermal  Operates from a core supply range of 1.14 V to 1.26 V and is specified for commercial temperature operation from 0 °C to 85 °C.
• Regulatory  RoHS‑compliant material status for environmental compliance in commercial electronics.

Typical Applications

• Embedded Controller and Glue Logic  Use the programmable fabric and embedded IP to implement control sequencing, protocol bridging, and board-level glue logic in compact systems.
• User Interfaces and Peripheral Aggregation  Combine the I/O count and hardened SPI/I2C IP to manage displays, keypads, sensors, and peripheral buses.
• Compact Consumer Electronics  The small 81‑WLCSP footprint and commercial temperature rating make the device suitable for space‑constrained consumer products requiring non‑volatile FPGA functionality.
• Low‑power, Space‑constrained Designs  Low-voltage core operation and a miniature package enable integration into designs where PCB area and power are limited.

Unique Advantages

• Compact, board‑level integration: The 81‑WLCSP (3.80 × 3.69 mm) package minimizes PCB area while preserving 63 I/Os for flexible connectivity.
• Non‑volatile, reprogrammable logic: Multi-time programmable configuration eliminates the need for an external configuration flash in many designs and supports in-system updates.
• Embedded system IP: Hardened I2C and SPI cores and on‑chip timer/counter functions reduce development time and external component count.
• Flexible clocking: On‑chip PLLs and oscillators (MachXO3 family features) simplify timing architectures without additional clock chips.
• Commercial temperature and RoHS compliance: Specified for 0 °C to 85 °C operation with RoHS‑compliant materials for mainstream commercial applications.
• Low‑voltage core operation: 1.14 V to 1.26 V supply range supports designs targeting modern low‑voltage domains.
