LCMXO640C-4TN100I

The LCMXO640C-4TN100I is a MachXO family field programmable gate array (FPGA) in a 100-pin surface-mount LQFP/TQFP package. It combines non-volatile configuration, a compact logic fabric and flexible I/O to address glue-logic, control and interfacing tasks in industrial designs.

With 640 logic elements and up to 74 user I/Os in the 100-pin package, this device targets applications requiring instant-on operation, in-field reprogramming and flexible voltage interfacing across a 1.71 V to 3.465 V supply range while operating from −40 °C to 100 °C.

Key Features

• Core Logic 640 logic elements implemented in a grid of programmable logic blocks suitable for glue logic, control and interfacing tasks.
• Non-Volatile, Instant-On Configuration Single-chip non-volatile architecture enables instant-on behavior and removes the need for external configuration memory.
• In-Field Reconfiguration TransFR™ reconfiguration and JTAG-programmable non-volatile and SRAM regions allow background programming and in-field logic updates while the system operates.
• Sleep Mode Low-power sleep capability to reduce static current by up to 100× for power-sensitive applications.
• Memory Distributed on-chip memory available for user designs; the MachXO640 family offers distributed RAM (family data indicates ~6.1 Kbits) and does not include embedded block SRAM.
• Flexible I/O Up to 74 I/Os in the 100-pin package with programmable I/O buffers supporting multiple voltage standards including LVCMOS (3.3/2.5/1.8/1.5/1.2), LVTTL, PCI and a range of differential interfaces listed for the family.
• Voltage and Power Operates across a broad supply range of 1.71 V to 3.465 V to match common system rails.
• Package & Mounting Surface-mount 100-pin package (100-LQFP / supplier device package 100-TQFP, 14×14 mm) for compact board designs.
• Industrial Temperature Grade Specified for operation from −40 °C to 100 °C.
• Environmental Compliance RoHS compliant packaging.

Typical Applications

• Glue Logic and Orchestration Replace discrete glue logic with a single programmable device to consolidate control signals and state machines.
• Bus Bridging and Interface Conversion Implement protocol translation and level shifting between system domains using flexible I/O and programmable logic.
• Power-Up and System Control Instant-on configuration and sleep mode support power sequencing, reset management and low-power control functions.
• Field Updatable Control Logic In-field reconfiguration enables firmware updates and feature additions without hardware changes.

Unique Advantages

• Single-Chip Non-Volatile FPGA: Eliminates external configuration memory and simplifies BOM and board layout.
• Instant-On Operation: Powers up in microseconds, enabling faster system availability and simpler power sequencing.
• Field Reconfiguration and Background Programming: Update logic in-system via JTAG or TransFR while the device remains in operation, reducing maintenance downtime.
• Wide I/O Voltage Support: Programmable I/O buffers accommodate multiple signalling standards and supply voltages, reducing the need for external level translators.
• Industrial Temperature Range: Qualified for −40 °C to 100 °C operation for reliable performance in demanding environments.
• Compact, Surface-Mount Packaging: 100-pin LQFP/TQFP package provides a small footprint solution with up to 74 I/Os for space-constrained designs.
