LCMXO640E-3B256I

The LCMXO640E-3B256I is a MachXO family field programmable gate array (FPGA) offered in a 256-ball LFBGA/CSPBGA package. It combines non-volatile, instant-on configuration with FPGA-style LUT-based logic to address glue logic, bus interfacing, control and system integration tasks across industrial applications.

With 640 logic elements, up to 159 I/Os, and industrial-grade temperature rating, this device is optimized for compact, reliable control and I/O-centric designs that require single-chip configuration and flexible in-field reprogramming.

Key Features

• Logic Capacity 640 logic elements provide LUT-based implementation for glue logic, bus bridging and control tasks.
• I/O Density 159 I/Os in the 256-LFBGA package support a wide range of peripheral and interface connections for dense I/O applications.
• Non-volatile, Instant-on Configuration Single-chip non-volatile configuration enables instant-on behavior and eliminates the need for external configuration memory.
• In-field Reconfiguration Supports TransFR™ reconfiguration and JTAG-based updates for in-system logic changes and background programming of non-volatile memory.
• Flexible sysIO™ Buffering Family-level I/O support includes LVCMOS (1.2–3.3V variants listed in the family datasheet), LVTTL, PCI and differential options such as LVDS and LVPECL for diverse interface requirements.
• Power and Sleep Modes Sleep mode enables significant static current reduction for low-power states.
• Package and Mounting 256-ball LFBGA (256-CABGA 14×14 mm supplier package) in a surface-mount form factor; RoHS compliant.
• Industrial Temperature Range Rated for operation from −40 °C to 100 °C for deployment in industrial environments.
• Core Supply Operates with a core supply range of 1.14 V to 1.26 V as specified for the part.
• Embedded and Distributed Memory (family) The MachXO640 family supports approximately 6.1 Kbits of distributed RAM (family-level specification).

Typical Applications

• System Glue Logic Replace discrete glue logic with programmable LUTs to simplify BOM and accelerate design changes.
• Bus Bridging and Interfacing Implement bus protocol adaptation and signal conditioning between subsystems using high I/O density and flexible I/O standards.
• Power-up and Control Sequencing Use instant-on non-volatile configuration for deterministic power-up sequencing and board-level control tasks.
• In-field Upgrades Enable firmware and logic updates in the field through JTAG and TransFR™ reconfiguration without removing the device.

Unique Advantages

• Single-chip Non-volatile Solution: Eliminates external configuration memory and enables instant-on operation for faster system bring-up.
• High I/O-to-Logic Ratio: 159 I/Os paired with 640 logic elements suits designs that are I/O-heavy but logic-moderate, reducing the need for larger devices.
• Industrial Reliability: −40 °C to 100 °C operating range and RoHS-compliant packaging support deployment in industrial environments.
• Field Reprogrammability: JTAG and background programming support for non-volatile memory allow updates without disrupting system operation.
• Flexible Interface Support (family-level): Programmable I/O buffers accommodate a variety of single-ended and differential standards for versatile connectivity.
