LCMXO3LF-4300E-5UWG81ITR50

The LCMXO3LF-4300E-5UWG81ITR50 is a MachXO3 family FPGA IC from Lattice Semiconductor, offered in a compact 81-WLCSP package for surface-mount assembly. It delivers a non-volatile, reprogrammable logic solution with 4,320 logic elements, 63 I/Os and 94,208 bits of embedded RAM for control and glue-logic tasks in industrial designs.

Designed for industrial-grade operation, the device supports a 1.14 V to 1.26 V supply range and an operating temperature range of -40 °C to 100 °C, making it suitable for embedded systems that require small form-factor programmable logic with on-chip memory and hardened system IP from the MachXO3 family.

Key Features

• Core Logic  4,320 logic elements providing programmable logic capacity for control, interfacing and system glue functions.
• Embedded Memory  94,208 total RAM bits of on-chip memory for buffering, FIFOs and small data storage needs.
• I/O and Interfaces  63 user I/Os enabling flexible connectivity to external devices and buses.
• Configuration and Hardened IP  MachXO3 family features include non-volatile, multi-time programmable configuration and embedded hardened IP blocks (family-level functions listed in the MachXO3 data sheet).
• Clocking and Timing  Family architecture includes flexible on-chip clocking and PLL support as documented in the MachXO3 data sheet.
• Power  Low-voltage operation with a specified supply range of 1.14 V to 1.26 V.
• Package and Mounting  81-WLCSP (3.80 × 3.69 mm) ultra-compact package, surface-mount mounting for space-constrained designs.
• Temperature and Grade  Industrial grade device rated for operation from -40 °C to 100 °C.
• Compliance  RoHS compliant.

Typical Applications

• Industrial Control  Programmable logic and interface functions in industrial equipment where the -40 °C to 100 °C operating range and industrial grading are required.
• Embedded System Integration  On-chip RAM and 63 I/Os allow implementation of glue logic, protocol adaptation and small bus controllers in compact embedded platforms.
• Interface Bridging  Use as a configurable bridge or I/O expander in systems that need reprogrammable I/O mapping and logic without external non-volatile configuration memory.

Unique Advantages

• Compact, surface-mount package: The 81-WLCSP (3.80 × 3.69 mm) package minimizes board area for space-constrained designs.
• Industrial temperature capability: Rated from -40 °C to 100 °C to support deployments in demanding environments.
• Integrated on-chip memory: 94,208 bits of embedded RAM reduce the need for external memory for buffering and small data storage.
• Low-voltage operation: Narrow supply window (1.14 V to 1.26 V) that supports low-power system designs and predictable power planning.
• Reprogrammable, non-volatile family features: MachXO3 family capabilities such as multi-time programmable configuration and embedded hardened IP enable flexible in-field updates and system integration.
• Good I/O density for its size: 63 I/Os provide broad interfacing options relative to the package footprint.
