LCMXO640C-3TN144C

The LCMXO640C-3TN144C is a MachXO family Field Programmable Gate Array (FPGA) in a 144-pin surface-mount package. It combines LUT-based logic with flexible programmable I/O to address glue logic, bus bridging, bus interfacing, power-up control and general control logic functions.

Designed for single-chip, non-volatile operation and rapid reconfiguration, this device delivers instant-on behavior and in-system update capabilities, making it suitable for embedded control and system glue applications in commercial-grade designs.

Key Features

• Core Logic  640 logic elements (LUTs) for implementing combinational and sequential logic functions; architecture uses LUT-based routing and logic resources.
• Memory  Approximately 6.1 Kbits of distributed RAM available in the LCMXO640 device (MachXO family memory architecture and allocation are shown in the datasheet).
• I/O and Interface Flexibility  113 programmable I/Os with sysIO™-style flexible buffers supporting a wide range of interfaces and I/O standards documented for the MachXO family.
• Non-volatile Configuration & In-system Updates  Single-chip non-volatile configuration for instant-on operation (no external configuration memory required). Supports JTAG programming, background programming of non-volatile memory, and in-field logic updates via TransFR™ reconfiguration.
• Low-power Modes  Sleep mode capability enables significant static current reduction (datasheet notes up to 100× reduction in static current).
• System Support  Family-level features include support for boundary-scan (IEEE 1149.1), onboard oscillator, and documented support from Lattice design tools for synthesis and place-and-route.
• Package, Supply and Temperature  Surface-mount 144-pin LQFP package, commercial grade (0 °C to 85 °C), voltage supply range 1.71 V to 3.465 V. RoHS compliant.

Typical Applications

• Glue Logic and Bus Bridging  Implement address decoding, signal multiplexing, bus width conversion and protocol adaptation without external configuration memory.
• Power-Up and System Control  Manage power sequencing, reset control and startup logic with instant-on non-volatile configuration.
• Control Logic and Peripheral Interfaces  Consolidate discrete control functions, peripheral interfacing and I/O conditioning in a single programmable device.
• Field-Upgradeable Logic  In-system reconfiguration enables rapid updates and bug fixes using background programming and TransFR reconfiguration while the system is running.

Unique Advantages

• Instant-on, single-chip configuration: Eliminates the need for external configuration memory and delivers rapid power-up behavior.
• High I/O density in a compact package: 113 I/Os in a 144-pin surface-mount package supports dense interfacing without larger packages.
• On-board, field-friendly updates: Reconfigure SRAM-based logic in milliseconds and program non-volatile memory via JTAG or background programming to enable in-field changes.
• Low-power operation options: Sleep mode capability provides substantial static current reduction for power-sensitive designs.
• Flexible supply and I/O support: Operates across a wide supply range (1.71 V–3.465 V) and uses the MachXO family’s programmable I/O buffer options to support multiple interface standards.
• Commercial-grade, compliant packaging: Rated for 0 °C to 85 °C operation and RoHS compliant for mainstream embedded applications.
