LCMXO256C-4MN100C

Product Overview

The Lattice Semiconductor Corporation LCMXO256C-4MN100C is a MachXO series field programmable gate array (FPGA) intended for embedded digital logic designs. It provides 256 logic elements/cells, 32 LABs/CLBs, and 78 I/O in a surface-mount 100-LFBGA, CSPBGA package; the device package is 100-CSBGA (8x8). The device operates from a 1.71V to 3.465V supply and is specified for a 0°C to 85°C (TJ) junction temperature range.

Key Features

• MachXO series FPGA architecture with 256 logic elements/cells and 32 LABs/CLBs.
• 78 I/O for embedded logic, control, and interface tasks.
• Supply voltage range of 1.71V to 3.465V.
• Surface-mount 100-LFBGA, CSPBGA package with 100-CSBGA (8x8) device package.
• Operating temperature range of 0°C to 85°C (TJ).

Applications

• Embedded control logic where custom digital functions must be implemented alongside a processor or microcontroller.
• I/O expansion and glue logic between peripheral devices and logic functions.
• Sensor aggregation, timing generation, and state-machine control in compact board designs.

Design & Procurement Notes

Design considerations should include fitting the target logic into 256 logic elements/cells and 32 LABs/CLBs, while reserving enough of the 78 I/O for external connections. The 1.71V to 3.465V supply range requires a compatible regulated power rail and decoupling. Because the package is a surface-mount 100-LFBGA, CSPBGA package with 100-CSBGA (8x8) device package, PCB land patterns, stencil openings, and thermal relief should be prepared for BGA assembly. The 0°C to 85°C (TJ) operating range should be checked against worst-case junction temperature in the final enclosure, not only ambient temperature.
