LCMXO640E-4T100I

The LCMXO640E-4T100I is a MachXO family FPGA that combines non-volatile, instant-on configuration with a compact 100-pin LQFP package. It delivers 640 logic elements, 74 user I/Os and family-level capabilities such as single-chip configuration, sleep mode, and in-field reconfiguration—making it suitable for glue logic, bus interfacing and control functions in industrial systems.

Key Features

• Logic Capacity 640 logic elements/cells provide flexible LUT-based implementation for glue logic, state machines and control functions.
• I/O and Package 74 user I/Os in a 100-LQFP (14×14 mm) package enable dense pin access in a small surface-mount form factor.
• Non-Volatile Instant-On Single-chip, non-volatile architecture powers up in microseconds and requires no external configuration memory.
• Memory Approximately 6.1 Kbits of distributed RAM for small buffers and distributed data storage; device has no embedded block SRAM.
• Reconfiguration and Programming Supports background programming and in-field reconfiguration of SRAM-based logic via JTAG and TransFR reconfiguration.
• Low-Power Modes Sleep mode provides substantial static current reduction for power-sensitive applications.
• Flexible I/O Buffering Family I/O buffer options support common logic standards (LVCMOS, LVTTL and others) for broad interface compatibility.
• Industrial Grade and Temperature Range Rated industrial grade with an operating temperature range of −40 °C to 100 °C for use in demanding environments.
• Power Core supply specification: 1.14 V to 1.26 V; designed for surface-mount assembly in the 100-LQFP package.

Typical Applications

• Glue Logic and System Integration: Implement glue logic, address decoding and protocol translation without external configuration memory, simplifying BOM and startup behavior.
• Bus Bridging and Interfacing: Use the flexible I/O buffering and 74 I/Os to implement bus bridges, level translation and interface adaptation.
• Control and Power-Up Sequencing: Implement power-up control, reset sequencing and supervisory logic with instant-on behavior.
• Embedded System Glue: Offload board-specific control tasks and small state machines to free microcontroller resources and reduce system complexity.

Unique Advantages

• Instant-on, single-chip solution: Eliminates external configuration memory and accelerates system startup, reducing component count and design complexity.
• Compact, high-pin-count package: 100-LQFP with 74 I/Os gives a small footprint while maintaining ample external connectivity for mid-density designs.
• Industrial temperature support: −40 °C to 100 °C rating addresses extended-temperature deployments and industrial applications.
• In-field reconfiguration: Background and TransFR programming let you update logic while the system operates, enabling post-deployment fixes and feature updates.
• Low-power operation: Sleep mode substantially reduces static current for energy-conscious designs and standby modes.
• Distributed RAM for runtime data: Built-in distributed RAM (≈6.1 Kbits) supports FIFOs, small buffers and local storage without external memory.

Why Choose LCMXO640E-4T100I?
