LCMXO640C-3T100C

The LCMXO640C-3T100C is a MachXO family field programmable gate array (FPGA) from Lattice Semiconductor Corporation, offered in a 100‑pin LQFP/TQFP (14×14 mm) package. It combines non‑volatile instant‑on operation and reconfigurable logic to address glue logic, bus bridging/interfacing, power‑up control and general control logic in commercial applications.

Designed for compact systems, the device provides 640 logic elements, 74 I/O pins and a flexible voltage supply range of 1.71 V to 3.465 V, delivering a single‑chip, reconfigurable solution for designs that require fast start‑up and in‑field update capability within a commercial temperature range of 0 °C to 85 °C.

Key Features

• Core Logic  640 logic elements (cells) suitable for glue logic, control-state machines and low‑to‑mid density FPGA tasks.
• Embedded and Distributed Memory  MachXO family devices include embedded and distributed memory options; the LCMXO640 family is specified with approximately 6.1 Kbits of distributed RAM in the family data sheet.
• Programmable I/O  74 I/O pins provided in the 100‑pin LQFP/TQFP package to support a variety of peripheral interfaces and board topologies.
• Non‑volatile, Instant‑on Architecture  MachXO family devices are single‑chip, non‑volatile FPGAs that power up in microseconds without external configuration memory and support in‑field reconfiguration.
• Reconfiguration and Programming  Supports fast SRAM‑based reconfiguration, background programming and JTAG access for device programming and updates while maintaining system operation.
• Power and Low‑Power Modes  Broad supply range (1.71 V to 3.465 V) with family features such as Sleep Mode for significant static current reduction.
• Package and Thermal  100‑pin LQFP (supplier lists 100‑TQFP, 14×14 mm) surface‑mount package; commercial grade operation from 0 °C to 85 °C.
• Compliance  RoHS compliant packaging as specified in the product data.

Typical Applications

• Glue Logic and System Control  Implement address decoding, protocol conversion and board‑level control functions with compact reconfigurable logic.
• Bus Bridging and Interfacing  Serve as a bus interface or bridge to adapt legacy and modern peripherals using flexible I/O and multiple signalling standards supported across the MachXO family.
• Power‑Up and Reset Control  Provide deterministic instant‑on behavior and manage system sequencing and watchdog functions.
• In‑field Logic Updates  Enable on‑the‑fly logic updates and feature upgrades without removing the device, leveraging background programming and TransFR reconfiguration capability in the MachXO family.

Unique Advantages

• Instant‑on, single‑chip solution: Non‑volatile architecture eliminates the need for external configuration memory and delivers rapid power‑up behavior.
• Flexible power support: Operates across a wide supply range (1.71 V to 3.465 V), enabling use with multiple supply rails and system designs.
• Compact packaging: 100‑pin LQFP/TQFP package balances pin count and board space for compact system implementations.
• Field reconfigurability: SRAM reconfiguration and background programming simplify updates and feature additions in the field.
• Low static power options: Sleep Mode capability in the MachXO family reduces static current for power‑sensitive designs.
• RoHS compliant: Environmentally compliant packaging supports regulatory and manufacturing requirements.
