LCMXO640C-4M100I

The LCMXO640C-4M100I is a MachXO family Field Programmable Gate Array (FPGA) IC offering 640 logic elements in a 100-ball LFBGA (csBGA) package. Optimized for glue logic, bus bridging and control functions, it provides a single-chip, non-volatile FPGA architecture with instant-on capability and flexible I/O for industrial embedded applications.

Key hardware attributes include 74 I/O pins, support for broad core supply voltages (1.71 V to 3.465 V), surface-mount 100-CSBGA (8×8 mm) packaging, and an industrial operating temperature range of -40 °C to 100 °C.

Key Features

• Core Logic — 640 logic elements to implement glue logic, state machines and control logic with efficient LUT-based architecture.
• Non-Volatile Instant-On — Single-chip non-volatile configuration enables rapid power-up (microsecond-class) without external configuration memory.
• In-Field Reconfiguration — Supports Reconfigure-on-the-fly and background programming through standard JTAG for in-system updates and maintenance.
• I/O Flexibility — 74 I/Os with programmable sysIO buffers supporting a wide range of interface standards for board-level interoperability.
• Embedded and Distributed Memory — Family data indicates support for distributed RAM; the LCMXO640 family provides approximately 6.1 Kbits of distributed RAM and no embedded block SRAM.
• Power and Temperature — Operates from 1.71 V to 3.465 V and specified for industrial temperatures from -40 °C to 100 °C.
• Package and Mounting — Surface-mount 100-LFBGA/csBGA (8×8 mm) package for compact board integration and reliable soldered mounting.
• System-Level Support — Family-level features include JTAG programming, IEEE 1149.1 boundary scan and support from ispLEVER design tools for synthesis, place-and-route and timing verification.

Typical Applications

• Glue Logic — Implement bus glue, address decoding and timing control with a compact, single-chip FPGA.
• Bus Bridging and Interfacing — Bridge disparate bus standards and handle protocol translation using flexible I/O and programmable logic.
• Power-Up and System Control — Manage power sequencing, reset logic and supervisory functions with fast, non-volatile configuration.
• Peripheral and User-Interface Control — Drive sensors, LEDs, switches and simple HMI logic while minimizing external components.

Unique Advantages

• Instant-on Non-Volatile Architecture: Single-chip configuration eliminates external memory and enables very fast system bring-up.
• Reduced BOM and Board Complexity: Integrated non-volatile config and flexible I/O reduce the need for separate configuration devices and interface glue components.
• Field Upgradeability: Background programming and JTAG-based updates allow in-field logic changes with minimal downtime.
• Industrial-Grade Operation: Specified for -40 °C to 100 °C and designed for surface-mount deployment in demanding environments.
• Design Ecosystem Support: ispLEVER tool compatibility and standard boundary-scan support streamline development and validation.
