LCMXO640C-4M100C

The LCMXO640C-4M100C is a member of the Lattice MachXO family of non-volatile, instant-on FPGAs. It provides 640 logic elements and 74 user I/Os in a 100‑ball LFBGA/CSPBGA package, targeting glue logic, bus interfacing, power-up control and general control logic where single-chip reconfigurability and compact packaging matter.

Engineered for commercial-grade applications, the device supports flexible supply voltages and in-field reconfiguration capabilities while offering a compact surface-mount package and a 0 °C to 85 °C operating range.

Key Features

• Core Logic 640 logic elements (LUT4-based) for implementing glue logic, state machines and interface control functions.
• On-chip Memory (family) Family-level support includes approximately 6.1 Kbits of distributed RAM for small buffers and register files (MachXO family specification).
• Instant-On, Non‑volatile Architecture MachXO family features single-chip, non-volatile configuration with instant-on behavior and no external configuration memory required.
• Reconfiguration and Programming Supports fast reconfiguration of SRAM-based logic and background programming of non‑volatile memory; family supports in-field TransFR™ reconfiguration for updates while the system operates.
• Low-Power Modes Family-level sleep mode capability provides up to 100× static current reduction for lower standby power.
• Flexible I/O and Voltage Support 74 I/Os with programmable I/O buffer support across common standards (family-level sysIO support for LVCMOS, LVTTL, LVDS, Bus-LVDS, LVPECL, RSDS and others) and device supply range of 1.71 V to 3.465 V.
• Package and Mounting 100‑LFBGA / CSPBGA (100‑CSBGA, 8×8 mm) surface-mount package suitable for space-constrained PCBs.
• Commercial Grade Temperature Rated for 0 °C to 85 °C operation (commercial grade).

Typical Applications

• Glue Logic and System Control Implement glue logic, power sequencing and board-level control functions where compact, reconfigurable logic is required.
• Bus Bridging and Interfacing Bridge or adapt between bus standards and manage protocol translation using the device’s flexible I/O and logic resources.
• Power-Up and Reset Control Implement power-up sequencing, reset supervision and supervisory control leveraging the single-chip, instant-on configuration.
• User Interface and Peripheral Control Manage buttons, LEDs, and peripheral interfaces with low pin-count logic and reconfigurable state machines.

Unique Advantages

• Instant-on, Single-Chip Configuration: Non‑volatile device architecture eliminates external configuration memory and provides rapid power-up behavior.
• Field Reconfiguration: TransFR™ and background programming enable in-field logic updates and non‑disruptive memory programming.
• Low Standby Power: Sleep mode capability (family-level) can reduce static current by up to 100× for energy‑sensitive systems.
• Compact Package with Ample I/O: 74 I/Os in a 100‑ball CSPBGA package deliver a high I/O-to-logic density ratio for space-constrained designs.
• Wide Supply Flexibility: Supports operation across a broad supply range (1.71 V to 3.465 V), easing integration with mixed-voltage systems.
• Design Ecosystem Support: MachXO family devices are supported by Lattice design tools and synthesis flows (family documentation references ispLEVER tools), facilitating design entry, place-and-route and timing verification.
