LCMXO640C-5FN256C

The LCMXO640C-5FN256C is a MachXO family FPGA device optimized for glue logic, bus bridging, power-up control and general control logic. This non-volatile, instant-on FPGA integrates 640 logic elements and up to 159 I/O in a compact 256‑ball BGA (17×17 mm) package for commercial embedded applications.

Designed for single‑chip system control and interface tasks, the device offers flexible I/O options, background reconfiguration capability, and low-power modes to help reduce board-level complexity and accelerate system startup.

Key Features

• Core Logic — 640 logic elements provide the equivalent of moderate-density programmable logic suitable for glue logic, bus interfacing and control tasks.
• I/O Density — Up to 159 programmable I/O pins in a 256‑BGA footprint enable high pin‑to‑logic connectivity for bus bridging and multi‑interface designs.
• Non‑volatile, Instant‑on — Single‑chip non‑volatile configuration enables microsecond power‑up behavior with no external configuration memory required.
• In‑field Reconfiguration — Supports in-system reconfiguration and background programming for field updates without removing the device.
• Flexible sysIO Buffer — Family I/O buffer support includes a wide range of interfaces (LVCMOS at multiple voltages, LVTTL, PCI, LVDS and others) for flexible board-level interfacing.
• Distributed Memory — MachXO family support includes distributed RAM (LCMXO640 family entry is specified with approximately 6.1 Kbits of distributed RAM in family documentation).
• Power and Sleep — Low-power sleep mode can significantly reduce static current during idle periods to extend system efficiency.
• Voltage Range — Operates across a wide supply range from 1.71 V to 3.465 V to accommodate mixed-voltage systems.
• Package and Mounting — 256‑ball FPBGA (17×17 mm) surface‑mount package for compact, high‑density board designs.
• Commercial Grade & RoHS — Commercial temperature grade (0 °C to 85 °C) and RoHS‑compliant packaging.

Typical Applications

• Glue Logic & System Control — Implement board-level orchestration, power sequencing and control state machines with fast, non‑volatile startup.
• Bus Bridging & Interface Translation — Use the device’s high I/O count and flexible I/O buffers to bridge disparate bus standards and perform protocol adaptation.
• Peripheral & Sensor Interfacing — Consolidate multiple sensor and peripheral interfaces into a single programmable device to reduce BOM and PCB area.
• Field‑Upgradeable Control Logic — Leverage in‑system reconfiguration and background programming to deploy updates without hardware changes.

Unique Advantages

• Instant‑on Non‑Volatile Configuration — Single‑chip configuration eliminates the need for external boot memory and enables immediate device availability after power‑up.
• High Pin‑to‑Logic Ratio — 159 I/Os with 640 logic elements provide a strong balance for designs that require many external signals relative to logic density.
• Flexible Voltage Support — Wide supply range (1.71 V–3.465 V) supports integration into mixed‑voltage systems without complex level‑shifting.
• Compact, Surface‑Mount BGA — 256‑ball (17×17 mm) FPBGA delivers high I/O density in a compact footprint for space‑constrained designs.
• Field Maintenance and Security — Background programming and non‑volatile configuration simplify field updates while avoiding external bitstream exposure.
