LCMXO256C-4TN100C

The LCMXO256C-4TN100C is a MachXO family, non-volatile FPGA optimized for low-capacity glue logic, bus bridging, power-up control and general control logic. It combines LUT-based logic with on-chip reconfiguration and single‑chip configuration memory for instant-on systems without the need for external configuration devices.

Packaged in a 100‑pin surface‑mount LQFP (14 × 14 mm) and rated for commercial operation from 0 °C to 85 °C, the device offers 256 logic elements and up to 78 I/O pins. It supports a wide supply range from 1.71 V to 3.465 V and is RoHS compliant.

Key Features

• Core Logic 256 logic elements (LUTs) suitable for glue logic, control logic and low-capacity FPGA tasks.
• Embedded & Distributed Memory Distributed RAM available as part of the MachXO family architecture to support small on-chip FIFOs and register files.
• I/O Capability Up to 78 programmable I/Os delivered in a 100‑pin package to support moderate pin‑count designs. Family I/O buffer support includes LVCMOS, LVTTL and a range of high-speed and differential interfaces.
• Non‑volatile, Instant‑On Configuration Single‑chip, non‑volatile configuration enables instant-on startup (power-up in microseconds) without external configuration memory and supports JTAG programming and background non‑volatile memory programming.
• Field Reconfiguration & Security TransFR™ in-field reconfiguration and JTAG-based programming permit updates while protecting configuration data by eliminating an external bitstream medium.
• Low‑Power Modes Sleep mode capability providing substantial static current reduction for low‑power applications.
• Package & Temperature 100‑pin LQFP surface‑mount package (supplier package listed as 100‑TQFP, 14 × 14 mm) and commercial operating temperature range of 0 °C to 85 °C.
• Standards & System Support Onboard oscillator, IEEE 1149.1 boundary scan and IEEE 1532 in‑system programming support for system-level test and in-field programmability.

Typical Applications

• Glue Logic and System Control Implement board-level glue logic, power sequencing and general control functions with on-chip non‑volatile configuration and instant‑on behavior.
• Bus Bridging and Interfacing Use the flexible I/O and 78 available pins to bridge buses, translate signaling standards and handle protocol interfacing on mixed-voltage systems.
• Power‑Up and Reset Control Leverage single‑chip configuration and fast startup to manage power sequencing and system initialization tasks.
• Field‑Updatable Logic Apply TransFR™ reconfiguration and JTAG programmability to deploy in-field logic updates without interrupting system operation.

Unique Advantages

• Single‑Chip Non‑Volatile Solution: Reduces BOM and eliminates the need for external configuration memory while enabling secure, instant-on startup.
• Fast Startup: Power-up in microseconds enables quicker system initialization and faster time-to-ready for embedded systems.
• Field Reconfiguration: In-field updates via TransFR™ and JTAG allow iterative firmware and logic changes without replacing hardware.
• Low‑Power Operation: Sleep mode provides significant static current reduction for energy‑sensitive designs.
• Flexible I/O Support: Programmable I/O buffers accommodate a wide range of signaling standards to simplify board-level integration.
• Compact Package with Moderate I/O Count: 100‑pin LQFP package offers up to 78 I/Os for mid‑density designs where board space and connector count matter.
