LCMXO640E-5T144C

The LCMXO640E-5T144C is a MachXO family FPGA from Lattice Semiconductor designed for low-capacity FPGA and CPLD-style use cases. It combines a non-volatile, instant-on architecture with a dense logic fabric—providing 640 logic elements and 80 logic blocks in a compact 144-pin LQFP/TQFP package.

Targeted at glue logic, bus bridging/interfacing, control and power-up sequencing, the device delivers flexible I/O and in-field reconfiguration capabilities that simplify system design and integration for commercial applications.

Key Features

• Logic Capacity — 640 logic elements across 80 logic blocks, suitable for glue logic, control, and interface tasks.
• I/O Density — 113 user I/Os in the 144-pin LQFP package, enabling broad connectivity for peripherals and buses.
• Non-Volatile, Instant-On — Single-chip, non-volatile configuration with instant-on behavior and no external configuration memory required.
• In-Field Reconfiguration (TransFR) — Supports background and in-field updates to reconfigure SRAM-based logic while the system operates.
• Embedded and Distributed Memory — MachXO family design provides distributed RAM; the LCMXO640 family entry supports approximately 6.1 Kbits of distributed RAM.
• Flexible I/O Buffering — sysIO buffer capabilities in the MachXO family support a wide range of interfaces (LVCMOS, LVTTL, PCI, LVDS, Bus-LVDS, LVPECL, RSDS) for system-level interoperability.
• Low-Power Modes — Sleep mode enables substantial static current reduction for power-sensitive designs.
• Core Supply Range — Core voltage supply specified at 1.14 V to 1.26 V for this device.
• Package and Temperature — 144-pin LQFP (supplier package listed as 144-TQFP 20×20) and commercial operating temperature range of 0 °C to 85 °C.

Typical Applications

• Glue Logic and Bus Bridging — Implement address decoding, protocol bridging, or bus interfacing where compact logic and flexible I/O are required.
• Power-Up and Control Sequencing — Instant-on configuration makes the device well-suited for power sequencing and system bring-up control tasks.
• Peripheral and Sensor Interfaces — 113 I/Os enable direct interfacing to sensors, displays, and external controllers without large external glue logic.
• In-Field Feature Updates — Use TransFR reconfiguration to update control logic or add features in deployed systems without taking the system offline.

Unique Advantages

• Single-Chip, Non-Volatile Configuration: Eliminates the need for external configuration memory and enables fast, deterministic power-up behavior.
• High Pin-to-Logic Efficiency: 113 I/Os paired with 640 logic elements provide strong I/O-to-logic density for interface-centric designs.
• Field Reconfiguration: TransFR and background programming support allow in-system updates and rapid feature iteration.
• Flexible Interface Support: Family-level sysIO buffer options accommodate a broad set of signaling standards to simplify board-level integration.
• Compact, Commercial Package: 144-LQFP / 144-TQFP (20×20) offers a standard, manufacturable footprint for cost-conscious commercial designs.
