LCMXO640C-4FT256C

The LCMXO640C-4FT256C is a MachXO family non-volatile FPGA delivering 640 logic elements and up to 159 user I/Os in a compact 256-ball BGA package. It is designed for glue logic, bus bridging, interface control and general system control tasks where instant-on operation and single-chip integration are important.

Built on the MachXO family architecture, the device provides single-chip instant-on behavior with background configuration and in-field reconfiguration capabilities, enabling reduced system BOM and fast system startup for commercial-temperature embedded designs.

Key Features

• Core Logic — 640 logic elements implemented across 80 logic blocks, enabling mid-density logic integration for control and interface functions.
• Non-volatile, Instant-On Architecture — MachXO family single-chip non-volatile architecture provides instant-on power-up in microseconds without external configuration memory.
• In-field Reconfiguration and Programming — Supports TransFR reconfiguration and reconfiguration of SRAM-based logic in milliseconds; non-volatile memory and SRAM are programmable through JTAG and support background programming (family-level capability).
• Memory — Approximately 6.1 Kbits of distributed RAM (family data for LCMXO640 devices) and no embedded block SRAM blocks specified for this density level.
• I/O Capacity and Flexibility — Up to 159 I/Os in the 256-ball package, suitable for multi-interface glue logic and bus interfacing roles.
• Power and Supply Range — Operates across a broad supply range from 1.71 V to 3.465 V to accommodate mixed-voltage designs.
• Low-Power Modes — Family supports a Sleep Mode to reduce static current consumption significantly (family-level capability).
• Package and Mounting — 256-LBGA surface-mount package; supplier device package specified as 256-FTBGA (17×17 mm) for compact board integration.
• Commercial Temperature Grade — Rated for 0 °C to 85 °C operation for commercial applications.
• RoHS Compliant — Environmental compliance for lead-free assembly.

Typical Applications

• Glue Logic and System Control — Replace discrete logic and simplify board-level control with compact, single-chip programmable logic.
• Bus Bridging and Interface Conversion — Implement bus interfacing and protocol translation functions leveraging the device's I/O count and programmable logic.
• Power-Up and Reset Control — Use instant-on capabilities and non-volatile configuration to manage system power sequencing and deterministic startup behavior.
• Peripheral and Sensor Interfacing — Aggregate and condition multiple signals for microcontrollers or SoCs using available I/Os and distributed memory.

Unique Advantages

• Single-Chip Non-Volatile Solution: Eliminates external configuration memory and enables instant-on operation, simplifying system design and improving boot determinism.
• Balanced I/O-to-Logic Density: 159 I/Os with 640 logic elements supports complex interfacing tasks without excessive device overhead.
• Compact, Surface-Mount Package: 256-ball ftBGA (17×17 mm) package enables high pin-count routing in a small PCB footprint for space-constrained designs.
• Flexible Supply Range: 1.71 V–3.465 V operation supports mixed-voltage systems and eases integration into existing power architectures.
• Design Tool Support: MachXO devices are supported by the vendor’s design tools (ispLEVER noted in family documentation), enabling synthesis, place-and-route, and timing verification workflows.
• Commercial Temperature Suitability: Rated 0 °C to 85 °C for a wide range of commercial embedded applications.
