Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ICE40LP640-CM36 is determined by the following criteria:

Mandatory Compatibility Parameters:

• Manufacturer: Lattice Semiconductor Corporation
• Series: iCE40™ LP
• Package Type: 36-VFBGA
• Number of I/O: 25
• Voltage Supply Range: 1.14V ~ 1.26V
• Operating Temperature: -40°C ~ 100°C (TJ)
• Mounting Type: Surface Mount

Allowable Variation Parameters:

• Logic Elements/Cells: May increase (upward compatible)
• Total RAM Bits: May increase (upward compatible)
• Number of LABs/CLBs: May increase (upward compatible)
