LCMXO3L-4300E-5UWG81ITR1K

Product Overview

The Lattice Semiconductor Corporation LCMXO3L-4300E-5UWG81ITR1K is an active MachXO3 field programmable gate array supplied in an 81-UFBGA, WLCSP package. The device provides 4320 logic elements/cells, 540 LABs/CLBs, 94208 total RAM bits, and 63 I/O pins. Its specified supply voltage range is 1.14V ~ 1.26V, and its operating temperature range is -40°C ~ 100°C (TJ). The package is a surface-mount 81-WLCSP (3.80x3.69) footprint, making it suitable for compact embedded logic and interface-bridging functions where programmable resource capacity and a small board area must be balanced.

Key Features

• 4320 logic elements/cells and 540 LABs/CLBs provide programmable logic capacity for embedded control and custom digital functions.
• 94208 total RAM bits are available as on-chip storage resources for temporary data storage and buffering.
• 63 I/O pins support external signal routing, peripheral interfacing, and board-level control paths.
• The specified supply voltage range is 1.14V ~ 1.26V, and the operating temperature range is -40°C ~ 100°C (TJ).
• The 81-UFBGA, WLCSP surface-mount package uses an 81-WLCSP (3.80x3.69) device footprint for compact PCB layouts.
• The part belongs to the MachXO3 series.

Applications

• Embedded control logic that replaces discrete combinational and sequential logic circuits.
• Interface bridging between digital subsystems such as microcontrollers, memories, and peripheral devices.
• On-chip data buffering for temporary storage of data blocks.
• Custom I/O expansion where 63 programmable pins are mapped to board signals.
• Compact programmable logic functions in space-constrained surface-mount assemblies.

Design & Procurement Notes

For board design, account for the 81-WLCSP (3.80x3.69) surface-mount package and the 63 I/O routing requirements. Confirm that the system power supply can meet the 1.14V ~ 1.26V supply range and that the junction temperature remains within -40°C ~ 100°C.
