LCMXO640C-4B256I

The LCMXO640C-4B256I is a MachXO family non-volatile FPGA optimized for control, glue-logic and interface tasks. The device combines instant-on, single-chip configurability with a compact 256-ball BGA package and a broad I/O count for flexible board-level integration.

With 640 logic elements and up to 159 I/Os in a 256-ball package, this surface-mount, industrial-grade device supports designs that require fast power-up, reconfigurability in the field, and operation across a wide supply and temperature range.

Key Features

• Non-volatile, instant-on architecture  Single-chip non-volatile configuration enables power-up in microseconds without external configuration memory.
• Logic density  640 logic elements provide capacity for glue logic, bus interfacing and control functions.
• Rich I/O  159 programmable I/Os in a 256-ball package enable high pin-to-pin connectivity for complex board interfaces.
• Embedded memory  MachXO family architecture provides distributed on-chip RAM (LCMXO640 family level: approximately 6.1 Kbits of distributed RAM).
• Wide supply range  Operates across a 1.71 V to 3.465 V supply range to support multiple I/O standards and mixed-voltage systems.
• Industrial temperature range  Rated for operation from −40 °C to 100 °C for robust performance in harsher environments.
• In-field reconfiguration  TransFR™ Reconfiguration (TFR) and background programming support allow updates to non-volatile logic while the system operates.
• Low-power modes  Sleep mode capability can reduce static current consumption by up to 100× for power-sensitive applications.
• Compact package  Available in 256-LFBGA / 256-CABGA (14×14 mm) surface-mount packages for space-constrained designs.
• Standards and tooling  MachXO family devices support IEEE 1149.1 boundary scan and are supported by the ispLEVER design tools for synthesis, placement and routing.
• RoHS compliant  Device meets RoHS requirements for environmental compliance.

Typical Applications

• Glue Logic and Board-Level Control  Implement control-state machines, reset sequencing and handshaking without external configuration components.
• Bus Bridging and Protocol Translation  Use the device’s I/O density and programmable buffers to implement bus interfacing and signal translation between subsystems.
• Power-Up and System Sequencing  Instant-on capability and non-volatile configuration simplify power sequencing and system bring-up tasks.
• Peripheral and Sensor Interfaces  High I/O count supports connecting multiple sensors, displays and peripherals in embedded control applications.

Unique Advantages

• Instant, single-chip configuration: Eliminates external configuration memory and delivers microsecond-level power-up for faster system readiness.
• Field reprogrammability: TransFR™ reconfiguration and background programming let you update logic in deployed systems without full shutdown.
• Versatile I/O and voltage support: Wide supply range and 159 I/Os enable mixed-voltage interfacing and flexible board-level integration.
• Industrial robustness: Rated −40 °C to 100 °C for reliable operation in demanding environments.
• Compact footprint with high pin count: 256-ball BGA packages provide a balance of I/O density and PCB area efficiency.
• Toolchain support: Supported by ispLEVER design tools for synthesis, placement and timing-aware routing to speed development.

Why Choose LCMXO640C-4B256I?
