LCMXO640C-4T100I

The LCMXO640C-4T100I is a MachXO family Field Programmable Gate Array (FPGA) in a 100-pin LQFP/TQFP package optimized for glue logic, interfacing and system control roles. It combines a non-volatile, instant-on architecture with reconfigurable logic to address bus bridging, power-up control and general-purpose control logic in industrial applications.

Key device characteristics include 640 logic elements, up to 74 I/Os in the 100-pin package, a wide supply range (1.71 V to 3.465 V), and an industrial operating temperature range of −40 °C to 100 °C—making it suitable for robust embedded designs requiring fast startup and flexible I/O.

Key Features

• Core Logic — 640 logic elements (LUT-based) provide flexible combinational and sequential logic resources for glue logic, protocol translation and control functions.
• Non‑volatile, Instant‑On — MachXO family architecture offers single-chip non-volatile configuration with instant-on power-up behavior and no external configuration memory required.
• Reconfiguration & Programming — Supports in-system programming and background programming; SRAM-based logic can be reconfigured in milliseconds and the family supports TransFR™ in-field updates.
• I/O Flexibility — 74 device I/Os (100-pin LQFP) with programmable I/O buffer options across a range of interface standards supported by the MachXO family.
• Power & Low‑Power Modes — Operates across a broad supply window (1.71 V to 3.465 V) and supports sleep mode for significant static current reduction.
• Memory (Family) — MachXO family devices provide distributed RAM options; the LCMXO640 family entry in the datasheet indicates support for distributed RAM resources.
• Package & Mounting — Available in a 100‑pin LQFP/TQFP (14 × 14 mm) surface-mount package for standard PCB assembly and prototyping workflows.
• Industrial Temperature Grade — Rated for operation from −40 °C to 100 °C for industrial applications.
• Standards & Compliance — RoHS compliant packaging as indicated in product data.

Typical Applications

• Glue Logic & System Control — Replaces discrete logic networks for control sequencing, reset distribution and state machines with a single reprogrammable device.
• Bus Bridging & Interface Translation — Implements protocol bridging and bus interfacing between different voltage domains and logic families using flexible I/O.
• Power‑Up and Reset Management — Handles power sequencing, supervision and deterministic startup behavior using non‑volatile instant-on configuration.
• Embedded Control & Peripheral Glue — Manage sensor interfaces, decode signals, and orchestrate peripheral control tasks in industrial embedded systems.

Unique Advantages

• Instant system readiness: Non-volatile configuration provides rapid power-up without external memory, simplifying BOM and board layout.
• Flexible I/O support: A high pin‑to‑logic ratio and programmable I/O buffer options enable multiple interface standards from a single device.
• Industrial robustness: Extended operating temperature range and surface-mount 100‑pin package support deployment in industrial environments.
• In‑field adaptability: Background programming and TransFR reconfiguration let you update logic while the system is running or in the field.
• Compact integration: Consolidates control and interfacing functions into one FPGA, reducing board area and component count.
