LCMXO256C-3TN100I

Product Overview

The LCMXO256C-3TN100I is a MachXO field programmable gate array from Lattice Semiconductor Corporation. It is a surface-mount integrated circuit in a 100-LQFP package, with a 100-TQFP (14 mm by 14 mm) device package. The device provides 78 I/O pins, 256 logic elements or cells, and 32 logic array blocks or configurable logic blocks. Its supply voltage range is 1.71 V to 3.465 V, and its junction temperature operating range is -40°C to 100°C. This configuration supports embedded systems that require custom digital logic in a surface-mount package.

Design & Procurement Notes

When selecting the LCMXO256C-3TN100I, verify that the system power supply remains within the 1.71 V to 3.465 V range across all operating conditions. Confirm that the PCB land pattern, clearance, and thermal path are appropriate for the 100-LQFP package, 100-TQFP (14 mm by 14 mm) surface-mount device package and that the junction temperature will not exceed 100°C. Evaluate whether 78 I/O pins provide sufficient external connectivity for the planned signals, and check that 256 logic elements or cells and 32 logic array blocks or configurable logic blocks meet the required logic capacity. Because the device is a field programmable gate array, pin assignment and logic behavior should be validated during design entry and board bring-up.
