LCMXO256E-4TN100C

The LCMXO256E-4TN100C is a MachXO family FPGA optimized for glue logic, bus bridging, bus interfacing, power‑up control and general control logic. It combines non‑volatile configuration with FPGA-style LUT-based logic to provide an instant‑on, single‑chip programmable solution for commercial applications.

Key attributes for this device include 256 logic elements, up to 78 I/O pins in a 100‑pin package, a core supply range of 1.14 V to 1.26 V, and a commercial operating temperature range of 0 °C to 85 °C—making it suitable for compact, low-latency control and interface functions where board‑level integration and fast power‑up are important.

Key Features

• Core Logic  Approximately 256 logic elements (LUT4-based architecture) arranged for efficient implementation of glue logic and control functions.
• Logic Blocks  32 logic blocks to support combinational and sequential logic implementation.
• I/O Density  Up to 78 programmable I/O pins in the 100‑pin package, enabling high pin‑to‑logic connectivity for bus interfacing and signal routing.
• Non‑volatile Configuration  MachXO family features include non‑volatile, instant‑on configuration with no external configuration memory required, enabling microsecond‑scale power‑up behavior and on‑chip design security.
• In‑field Reconfiguration  Family-level TransFR™ reconfiguration allows in‑field logic updates while systems remain operational; the MachXO architecture supports background programming of non‑volatile memory.
• Memory  No dedicated embedded block RAM (EBR) in this device; datasheet family information indicates distributed RAM is available at the family level for the LCMXO256 device.
• Power and Low‑Power Modes  Core supply range: 1.14 V to 1.26 V. Family features include a Sleep Mode that can reduce static current by up to 100×, supporting low‑power system states.
• I/O Standards (family‑level)  Family programmable sysIO buffers support a wide range of interfaces (LVCMOS, LVTTL, PCI, LVDS, Bus‑LVDS, LVPECL, RSDS) as described in the MachXO family documentation.
• Package and Grade  100‑pin package (listed as 100‑LQFP; supplier package noted as 100‑TQFP, 14×14 mm). Commercial grade device rated for 0 °C to 85 °C operation.
• Environmental Compliance  RoHS compliant.

Typical Applications

• Glue Logic and Signal Integration  Implement board-level glue logic and pin multiplexing where compact, reconfigurable logic is required.
• Bus Bridging and Interfacing  Bridge or interface between different bus standards and I/O voltages using abundant I/O and programmable buffers.
• Power‑Up and System Control  Manage power sequencing, reset logic and startup behaviors benefiting from non‑volatile instant‑on configuration.
• Control Logic  Implement state machines, protocol handling and peripheral control in a single-chip programmable device.

Unique Advantages

• Instant‑on, single‑chip configuration: Eliminates external configuration memory and enables microsecond power‑up behavior for faster system availability.
• High I/O to logic ratio: Up to 78 I/Os paired with 256 logic elements simplifies board routing and reduces the need for additional interface components.
• Field update capability: Family TransFR reconfiguration and background non‑volatile programming support in‑field updates and iterative development.
• Low‑power standby: Sleep Mode (family feature) supports substantial static current reduction for energy‑sensitive designs.
• Commercial temperature and RoHS compliance: Rated for 0 °C to 85 °C operation and RoHS compliant for standard commercial product deployments.
• Compact 100‑pin package: 100‑pin LQFP/TQFP (14×14 mm) provides a compact footprint for space‑constrained designs.
