LCMXO640E-5T100C

The LCMXO640E-5T100C is a MachXO family FPGA offering 640 logic elements and 74 general-purpose I/Os in a 100-pin LQFP surface-mount package. Optimized for glue logic, bus bridging, power-up control and control-logic functions, this commercial-grade device delivers a single-chip, non-volatile, instantly available programmable fabric for system and board-level control.

As a member of the MachXO family, the device supports fast power-up, in-field reconfiguration and flexible I/O standards to simplify integration in space- and power-constrained designs while enabling background programming and design security.

Key Features

• Non-volatile, instant-on architecture  Single-chip non-volatile configuration that powers up in microseconds and requires no external configuration memory.
• Reconfiguration and programmability  Support for JTAG programming and TransFR™ in-field reconfiguration to update logic while the system operates; background programming of non-volatile memory is supported.
• Logic capacity  640 logic elements suitable for glue logic, control paths and interface bridging.
• I/O and interface flexibility  74 I/Os with programmable sysIO™ buffers that support a broad set of interfaces and voltage standards, including LVCMOS (1.2V–3.3V ranges), LVTTL, PCI, LVDS, Bus-LVDS, LVPECL and RSDS.
• Embedded and distributed memory (family)  MachXO family architecture provides distributed RAM resources (LCMXO640 family entry indicates 6.1 Kbits of distributed RAM) and family-level memory features for control and buffering.
• Low-power modes  Sleep mode can reduce static current by up to 100× for lower-power standby operation.
• Package and mounting  100-pin LQFP (100-TQFP, 14×14 mm) surface-mount package for straightforward PCB assembly and prototyping.
• Power and environmental  Operates from 1.14 V to 1.26 V supply rails and is specified for commercial temperature operation from 0 °C to 85 °C. RoHS-compliant packaging.

Typical Applications

• Glue Logic and System Control  Implement board-level control, reset sequencing and power-up logic with instant-on behavior.
• Bus Bridging and Protocol Interfacing  Use programmable I/O and flexible voltage standards to bridge disparate buses and manage peripheral interfaces.
• Power and Reset Management  Integrate power-up sequencing, watchdog and supervisory functions using non-volatile configuration and reconfigurable logic.
• Board-Level Peripheral Control  Manage sensor interfaces, user I/O and simple state machines where compact, single-chip programmability reduces BOM count.

Unique Advantages

• Single-chip non-volatile solution: Eliminates external configuration memory and enables instant-on operation, simplifying system boot and reducing component count.
• In-field reconfiguration: TransFR™ capability and JTAG programmability enable safe, background and live updates to logic without removing the device from the system.
• Flexible interface support: Programmable sysIO buffers support a wide range of signaling standards, making it easier to interface with modern peripherals and legacy buses.
• Low standby power: Sleep mode offers substantial static current reduction for power-conscious designs.
• Compact, surface-mount package: 100-LQFP footprint provides 74 I/Os and 640 logic elements in a board-friendly form factor for space-constrained applications.
• Design tool support: MachXO family devices are supported by the MachXO design flow and ispLEVER tools to streamline synthesis, placement and routing.
