LCMXO640C-4T144I

Field Programmable Gate Array Overview

The LCMXO640C-4T144I is a non-volatile Field Programmable Gate Array from the MachXO family, featuring 640 Look-Up Tables (LUTs) and up to 159 I/O pins. It operates on a single chip without external configuration memory, utilizing internal Flash for instant-on capabilities in microseconds. The device supports multiple voltage supplies including 3.3V, 2.5V, 1.8V, and 1.2V. It includes 6.1 Kbits of distributed RAM and lacks embedded block RAM. The unit is housed in a 144-pin TQFP package with a -40°C to +100°C operating temperature range.

Field Programmable Gate Array Feature Summary

• Non-volatile architecture enabling instant power-up and infinite reconfigurability via TransFR technology.
• Flexible sysIO buffers supporting diverse interface standards such as LVCMOS, LVTTL, PCI, and LVDS.
• Integrated JTAG port for programming, configuration, and background non-volatile memory updates.

Field Programmable Gate Array Applications

• Bus bridging and interfacing between disparate system components.
• Glue logic implementation for complex digital systems.
• Power-up control and initialization management circuits.
• General-purpose I/O expansion for embedded applications.

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'C' against the manufacturer's current documentation to confirm the commercial temperature grade (-40°C to +85°C). Ensure the design tool version supports the MachXO family syntax. Confirm RoHS compliance status through official datasheets prior to final procurement decisions.

Field Programmable Gate Array Selection Notes

Select this model when non-vatility and instant-on functionality are required without external configuration chips. Compare resource requirements against the LCMXO256C or LCMXO1200C if density needs differ. Verify that the 144-pin TQFP package dimensions fit the target PCB layout constraints.

Field Programmable Gate Array Part Context

This component belongs to the original MachXO family, distinct from the later MachXO2 series which features different memory architectures and lower power profiles. It serves as a bridge between traditional CPLDs and low-capacity FPGAs, offering FPGA flexibility with CPLD-like security and boot times.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible replacements within the same family include LCMXO640C-5TG144I for higher speed grades. For migration to newer technologies, consult Lattice documentation regarding the transition from MachXO to MachXO2 or MachXO3LF families, noting architectural differences in memory and I/O banks.
