LCMXO640C-3T144C

The LCMXO640C-3T144C is a MachXO series FPGA from Lattice Semiconductor designed for glue logic, bus bridging, control and interface tasks where non-volatile, instant-on logic is required. The device integrates 640 logic elements and 113 I/Os in a 144-pin LQFP package for compact, surface-mount designs in commercial-temperature systems.

Built on the MachXO family architecture, the device provides single-chip, non-volatile reconfigurable logic with features such as instant-on operation, background programming and low-power sleep mode that simplify system design and reduce external components.

Key Features

• Logic Density — 640 logic elements for implementing glue logic, state machines and interface functions.
• I/O Count & Package — 113 I/Os in a 144-LQFP package; supplier device package listed as 144-TQFP (20×20).
• Non-Volatile, Instant-On — Single-chip non-volatile architecture that powers up in microseconds and requires no external configuration memory.
• Reconfiguration & Programming — Supports in-field reconfiguration and reprogramming through JTAG, including background programming of non-volatile memory and TransFR™ reconfiguration for updates while the system operates.
• Low-Power Modes — Sleep mode enables significant static current reduction for power-sensitive applications.
• Flexible I/O Buffering — Family sysIO™ buffer support for a wide range of interfaces as described in the MachXO family data (LVCMOS, LVTTL, LVDS and others).
• System Support — Onboard oscillator and IEEE 1149.1 boundary-scan support; devices operate across multiple supply levels per family guidelines.
• Electrical & Mechanical — Surface-mount device; voltage supply range 1.71 V to 3.465 V; operating temperature range 0 °C to 85 °C; RoHS compliant.

Typical Applications

• Board-Level Glue Logic — Replace discrete glue components with reconfigurable logic for bus interfacing, control sequencing and address decoding.
• Interface Bridge — Implement protocol translation and signal conditioning using the device’s flexible I/O and abundant I/O count.
• Power-Up & Control Logic — Use instant-on, non-volatile configuration to implement startup sequences, reset control and system state machines.
• Field-Updatable Logic — In-system reconfiguration and background programming enable firmware-style updates to control logic without external configuration memory.

Unique Advantages

• Single-Chip Non-Volatile Design: Eliminates the need for external configuration memory and delivers instant-on capability for faster system readiness.
• Compact, High I/O Count: 113 I/Os in a 144-pin surface-mount package reduces board count and simplifies routing in constrained designs.
• Reconfigurable In-Field: TransFR™ and JTAG-programmable non-volatile memory let you update logic in deployed systems without full shutdown.
• Power Efficiency: Sleep mode provides substantial static current reduction for low-power standby states.
• Commercial Temperature Compatibility: Rated for 0 °C to 85 °C operation to match typical commercial embedded applications.
• RoHS Compliant: Meets RoHS requirements for lead-free manufacturing and assembly.
