LCMXO2-640UHC-4TG144C

The LCMXO2-640UHC-4TG144C is a MachXO2 family field programmable gate array (FPGA) IC from Lattice Semiconductor. It delivers a compact, low-power programmable logic solution with flexible I/O and on-chip memory suitable for commercial embedded designs.

Built on the MachXO2 architecture, this device targets applications that require instant-on non-volatile configuration, extensive I/O connectivity and integrated memory for glue logic, interface adaptation, and peripheral control in commercial products.

Key Features

• Core capacity — 640 logic elements providing programmable logic resources for glue logic, protocol adaptation, and small to medium complexity logic functions.
• On-chip memory — 65,536 total RAM bits (approximately 64 kbits) of embedded memory for state, buffering and small data storage needs.
• I/O density and flexibility — 107 I/Os in a 144‑pin LQFP package to support multiple external interfaces and dense system connections.
• Package and mounting — Surface mount 144‑LQFP (supplier device package listed as 144‑TQFP 20×20) for easy PCB integration in compact commercial products.
• Power and supply range — Operates from 2.375 V to 3.465 V, enabling compatibility with common commercial voltage rails.
• Commercial temperature grade — Specified operating temperature range of 0 °C to 85 °C for standard commercial environments.
• Family-level low-power features — MachXO2 family includes ultra low power options, standby modes and other power-saving capabilities for energy-sensitive designs.
• Non-volatile, reconfigurable operation — MachXO2 family supports instant-on, single-chip non-volatile configuration, in-field reconfiguration and background programming for flexible system updates.
• Enhanced system support (family features) — On-chip peripherals such as SPI, I²C and timers, plus programmable I/O buffer options and pre‑engineered source‑synchronous I/O support available across the MachXO2 family.
• Compliance — RoHS compliant.

Typical Applications

• Consumer electronics — Interface and peripheral control where compact packaging, flexible I/O and low-power standby are important.
• Communications equipment — Protocol bridging and signal conditioning using the device’s ample I/O and embedded memory for buffering and translation.
• Embedded control and glue logic — Replace discrete logic and simplify BOM with programmable logic and onboard memory tailored to commercial embedded systems.
• Prototyping and system bring-up — Instant-on non-volatile configuration and in-field reprogramming accelerate development cycles and iterative design changes.

Unique Advantages

• Compact, high-density I/O in a standard package: 107 I/Os in a 144‑LQFP package simplify routing and connector integration for dense commercial PCBs.
• On-chip embedded memory: Approximately 64 kbits of RAM reduces external memory needs for buffering and small data storage.
• Wide supply range: 2.375 V to 3.465 V support simplifies integration with common commercial power rails.
• Instant-on, non-volatile configuration: MachXO2 family instant-on capability and reconfiguration support speed system boot and enable in-field updates.
• Commercial temperature suitability: Specified 0 °C to 85 °C operating range aligns with typical commercial product requirements.
• RoHS compliant: Meets standard environmental requirements for commercial manufacturing.
