LCMXO640E-5TN100C

The LCMXO640E-5TN100C is a MachXO family FPGA optimized for glue logic, bus bridging, power-up control and general control logic. It provides 640 logic elements in a single, non-volatile device with instant-on behavior and in-field reconfiguration capabilities.

Packaged in a 100-pin LQFP (surface-mount) and rated for commercial operation from 0 °C to 85 °C, the device exposes 74 I/Os and is specified for a core supply range of 1.14 V to 1.26 V. It is lead free and RoHS compliant.

Key Features

• Non-volatile, instant-on architecture Single-chip non-volatile configuration enables microsecond power-up and eliminates the need for external configuration memory.
• Reconfigurable while deployed TransFR™ reconfiguration and background programming let you update SRAM-based logic and non-volatile memory in-system.
• Logic capacity 640 logic elements provide flexible resources for glue logic, control paths and interface bridging.
• Memory Approximately 6.1 Kbits of distributed RAM for small FIFOs and state storage; this device does not include embedded block SRAM (EBR).
• I/O and programmable buffers 74 I/Os in the 100-pin LQFP package with sysIO™ programmability supporting a wide range of interfaces including LVCMOS (3.3/2.5/1.8/1.5/1.2 V), LVTTL, PCI, LVDS, Bus‑LVDS and RSDS.
• Power and low-power modes Core supply specified at 1.14–1.26 V and a Sleep Mode that reduces static current for lower power standby operation.
• System integration features JTAG programmability, onboard oscillator, IEEE 1149.1 boundary-scan and IEEE 1532 in-system programming support system-level debug and in-field updates.
• Package and grade Surface-mount 100-LQFP (14 × 14 mm) package; commercial grade (0 °C to 85 °C) and RoHS compliant.

Typical Applications

• Glue Logic and Signal Conditioning Implement custom combinatorial and sequential glue logic to adapt peripheral timing and control without external discrete glue components.
• Bus Bridging and Protocol Conversion Bridge between buses and translate interface standards using the device’s flexible I/O buffer and reconfigurable logic.
• Power-up and Reset Control Manage system power sequencing and reset logic with instant-on behavior and non-volatile configuration.
• Control and Interface Management Replace small CPLD or fixed-function control ICs with a reprogrammable device for UI control, sensor interfacing and small state machines.

Unique Advantages

• Single-chip non-volatile solution: Eliminates external configuration memory and provides immediate functionality at power-up.
• Field reconfigurability: TransFR™ and background programming let you update logic and non-volatile memory without removing the device from the system.
• Flexible I/O support: Programmable sysIO buffers support a wide set of signaling standards, reducing the need for level shifters and interface ICs.
• Compact package with ample I/O: 74 I/Os in a 100-LQFP package supports dense board designs while keeping PCB footprint small.
• Low-power standby: Sleep Mode enables substantial static current reduction for battery-aware or low-power applications.
• Design tool ecosystem: Supported by ispLEVER design tools (synthesis, place-and-route and timing back-annotation) to streamline development and verification.
