LCMXO640C-4BN256C

The LCMXO640C-4BN256C is a MachXO family non-volatile FPGA optimized for glue logic, bus bridging, power-up control and general control logic. It combines instant-on non-volatile configuration with a compact logic fabric—640 logic elements and up to 159 I/Os—delivered in a 256-ball LFBGA/CSPBGA package for space-efficient surface-mount designs.

Designed for commercial applications, this device offers field reconfiguration, low-power sleep capability and flexible I/O support across a wide supply voltage range, enabling fast system startup and simplified board-level integration.

Key Features

• Core Logic — 640 logic elements (LUT-based) with 80 logic blocks (CLBs) to implement glue logic, control state machines and interface glue.
• I/O Density — Up to 159 user I/Os in the 256-ball package, enabling high pin-to-logic connectivity for complex interface and bridging tasks.
• Embedded Memory — Approximately 6.1 Kbits of distributed RAM (MachXO family data) and no embedded block SRAM (EBR) for small data buffering and distributed storage.
• Non-volatile, Instant-On — Single-chip non-volatile architecture provides immediate configuration at power-up without external memory (MachXO family behavior).
• In-field Reconfiguration — Supports background and in-field reprogramming capabilities for design updates while systems remain in operation (TransFR reconfiguration).
• Flexible I/O Standards — Programmable I/O buffers supporting a broad set of interfaces (family-level sysIO support), enabling mixed-voltage system interfacing.
• Power and Low-Power Modes — Operates from 1.71 V to 3.465 V and includes a sleep mode for significant static current reduction (family-level feature).
• Package and Mounting — Surface-mount 256-LFBGA/CSPBGA (supplier device package: 256-CABGA, 14×14 mm) for compact PCB footprint.
• Commercial Temperature Grade — Operating range 0 °C to 85 °C; RoHS compliant.

Typical Applications

• Glue Logic and System Control — Replace discrete logic networks and CPLDs with a single-chip solution for power-up sequencing, reset logic and board-level control.
• Bus Bridging and Interface Conversion — Implement protocol adaptation and bus interfacing where high I/O count and flexible I/O standards are required.
• Peripheral and Sensor Interfacing — Aggregate and format signals from sensors and peripherals, leveraging distributed RAM for small buffering tasks.
• Field Upgradeable Logic — In-field reconfiguration capability lets you update control logic or add features without replacing hardware.

Unique Advantages

• Instant-on non-volatile operation — Eliminates the need for external configuration memory and enables fast system startup.
• High I/O-to-logic ratio — 159 I/Os combined with 640 logic elements supports dense interfacing while keeping the logic fabric compact.
• Field reprogrammability — Background and in-field programming reduce maintenance complexity and allow iterative feature updates.
• Wide supply voltage support — 1.71 V to 3.465 V operation allows use in systems with multiple core and I/O voltage domains.
• Compact BGA packaging — 256-ball LFBGA/CSPBGA (14×14 mm) minimizes PCB area while providing abundant I/O.
• Commercial-grade reliability — Rated for 0 °C to 85 °C operation and RoHS compliant for standard commercial deployments.
