LCMXO640C-4FT256I

The LCMXO640C-4FT256I is a MachXO family Field Programmable Gate Array (FPGA) in a 256-ball ftBGA (17×17) package, offering approximately 640 logic elements and up to 159 I/Os in a single, non-volatile device. It targets applications that require glue logic, bus interfacing, power-up control and other system control functions where instant-on behavior and reconfigurability are valuable.

Designed for industrial use, the device supports a wide supply range and extended temperature operation, delivering board-level integration and design flexibility for control, bridging and interface tasks in embedded systems.

Key Features

• Core Logic  Approximately 640 logic elements (LUT-based architecture) suitable for implementing glue logic, bus bridging and control tasks.
• I/O Density  Up to 159 I/Os in the 256-ball ftBGA package, enabling high pin-to-pin connectivity for complex interfacing.
• Non-volatile, Instant-on  MachXO family characteristics include single-chip non-volatile configuration and instant-on operation without external configuration memory.
• In-field Reconfiguration  Supports background programming and TransFR reconfiguration for in-field logic updates while the system operates.
• Memory  Family data indicates distributed RAM capability (LCMXO640: approximately 6.1 Kbits distributed RAM) for small embedded storage and FIFO control logic; this part provides the MachXO family memory architecture.
• Flexible I/O Standards  MachXO family sysIO buffering supports multiple interface standards (examples listed in family datasheet include LVCMOS, LVTTL, PCI, LVDS, Bus-LVDS, LVPECL, RSDS), enabling a wide range of signaling options.
• Voltage Supply  Specifies operation across a broad supply range from 1.71 V to 3.465 V for flexible system integration.
• Packaging & Mounting  256-ball ftBGA (17×17 mm) package, surface-mount mounting type for compact board designs.
• Industrial Temperature Grade  Rated for operation from −40 °C to 100 °C for use in industrial environments.
• Low-Power Modes  MachXO family features include a sleep mode that allows substantial static current reduction for low-power standby operation.

Typical Applications

• Glue Logic and System Control  Implement glue logic, power-up sequencing and control-state machines without external configuration devices thanks to the device’s non-volatile architecture.
• Bus Bridging and Interfacing  High I/O count and flexible I/O buffer options make the device suitable for bridging between different bus standards and signal domains.
• Embedded Control  Use in control logic for industrial equipment, managing peripheral interfaces and board-level sequencing within extended temperature ranges.
• In-field Upgrades  Background programming and TransFR reconfiguration enable field updates to control logic while the system remains operational.

Unique Advantages

• Single-chip, non-volatile configuration: Eliminates the need for external configuration memory and provides instant-on system behavior.
• High pin-to-function ratio: 159 I/Os combined with ~640 logic elements delivers strong connectivity for dense interfacing tasks without large FPGA overhead.
• Wide supply and temperature range: 1.71 V–3.465 V operation and −40 °C to 100 °C rating support robust integration into industrial systems.
• Field reprogrammability: Supports background programming and in-field TransFR updates to enable incremental feature upgrades and bug fixes.
• Compact BGA package: 256-ball ftBGA (17×17) allows a high I/O count in a small footprint for space-constrained boards.
• Toolchain and ecosystem support: The MachXO family is supported by ispLEVER design tools for synthesis, place-and-route and timing analysis to streamline development.
