LCMXO640C-4TN144C

The LCMXO640C-4TN144C is a MachXO family field programmable gate array supplied in a 144-pin LQFP surface-mount package. It offers 640 logic elements and 113 I/O pins in a compact, commercial-grade footprint, supporting core supply voltages from 1.71 V to 3.465 V and operation from 0 °C to 85 °C.

Designed for glue logic, bus bridging, interface control and power-up/control logic, this MachXO device combines non-volatile, reconfigurable logic with instant-on behavior and features that support in-field updates and reduced static power modes.

Key Features

• Logic Capacity 640 logic elements (LUT-based) for implementing glue logic, control paths and interface functions.
• Non-volatile, Instant-on Architecture MachXO family capability: non-volatile configuration provides instant-on operation and eliminates the need for external configuration memory.
• In-field Reconfiguration (TransFR) Family-level TransFR reconfiguration support enables logic updates while the system remains operational.
• Sleep Mode Family-level sleep mode support enables significant static current reduction for lower-power standby operation.
• I/O Density 113 programmable I/O pins available in the 144-LQFP package, suitable for rich peripheral and bus interfacing.
• On-chip Memory Total on-chip RAM reported as 0 bits for this device; logic implementation is provided via LUT-based elements.
• Power and Temperature Supply voltage range 1.71 V to 3.465 V; commercial operating temperature range 0 °C to 85 °C.
• Package and Mounting 144-pin LQFP surface-mount package (supplier package listed as 144-TQFP 20×20 mm) for straightforward PCB integration.
• Regulatory RoHS compliant.

Typical Applications

• Glue Logic and System Control Implement combinational and sequential glue logic, reset and power sequencing control with instant-on behavior.
• Bus Bridging and Interfacing Route, translate and buffer signals between system buses and peripherals using the device’s 113 I/Os.
• Power-Up and Reset Management Centralize power-up sequencing and supervisory control functions in a single non-volatile device.
• User Interface and Control Logic Drive and manage button inputs, status indicators and simple state machines for commercial embedded products.

Unique Advantages

• Single-chip, instant-on configuration: Eliminates external configuration memory and delivers usable logic immediately after power-up.
• Secure configuration storage: Non-volatile configuration avoids an external bitstream that could be intercepted.
• Field-update capable: TransFR reconfiguration enables in-system logic updates without full system downtime.
• Compact, high I/O density: 113 I/Os in a 144-LQFP package reduce PCB area while supporting diverse peripheral connections.
• Low-power standby: Sleep mode capability allows substantial static current reduction for energy-sensitive designs.
• Toolchain support: MachXO family devices are supported by vendor design tools for synthesis, placement and routing.
