LCMXO640C-5M100C

The LCMXO640C-5M100C is a MachXO family Field Programmable Gate Array (FPGA) from Lattice Semiconductor designed for single-chip, non-volatile logic implementations. It combines 640 logic elements with up to 74 I/Os in a compact 100-ball LFBGA/CSPBGA package for space‑efficient board designs.

Optimized for glue logic, bus bridging, bus interfacing, power‑up control and general control logic, the device delivers instant-on non‑volatile operation, flexible I/O buffering and in-field reconfiguration options while operating over a wide supply range and commercial temperature grade.

Key Features

• Core Logic  640 logic elements (LUT4 architecture) suitable for glue logic and control functions; family architecture supports density migration across MachXO devices.
• Memory  Approximately 6.1 Kbits of distributed RAM (family data); no embedded block SRAM (EBR) in this density point.
• I/O  74 user I/Os with a programmable sysIO buffer supporting a wide range of interfaces, including LVCMOS (3.3/2.5/1.8/1.5/1.2), LVTTL, PCI, LVDS, Bus‑LVDS, LVPECL and RSDS.
• Non‑volatile, Instant‑on  Single‑chip non‑volatile architecture provides instant-on operation without external configuration memory and supports background programming and in-field updates.
• Reconfiguration  TransFR™ reconfiguration enables in-field logic updates while the system is operating; SRAM-based logic can be reconfigured in milliseconds and non‑volatile memory can be programmed via JTAG.
• Low‑power Modes  Sleep mode available for up to 100× static current reduction to minimize standby power consumption.
• Power and Clocking  Operates across a wide VCC range (1.71 V to 3.465 V); family devices include onboard oscillator and system clock support (family-level PLL options vary by density).
• Packaging and Grade  Available in a 100‑LFBGA / 100‑ball csBGA (8×8 mm) package; commercial grade with an operating temperature range of 0 °C to 85 °C.
• System Support  Supports IEEE 1149.1 boundary scan and IEEE 1532 in-system programming for board-level testability and field programming.

Typical Applications

• Glue Logic and Control  Implement glue logic to integrate ASICs, microcontrollers and peripherals with compact, reprogrammable logic in a single chip.
• Bus Bridging and Interfacing  Bridge or adapt between bus standards and manage signal conditioning with flexible I/O options and programmable buffers.
• Power‑up and Reset Control  Centralize power sequencing, reset distribution and system supervision using instant‑on, non‑volatile logic that initializes in microseconds.
• Peripheral and UI Control  Manage user interfaces, LEDs, buttons and local peripherals where compact footprint and reconfigurability speed product updates.

Unique Advantages

• Single‑chip non‑volatile design: Eliminates the need for external configuration memory for simpler BOM and faster start-up.
• Instant‑on capability: Powers up in microseconds to meet fast initialization requirements in embedded systems.
• Field reconfiguration: TransFR™ and JTAG programming enable in‑field updates and background programming without taking the system offline.
• Flexible I/O support: Broad interface support (LVCMOS/LVTTL/PCI/LVDS and more) simplifies integration across mixed‑signal and mixed‑voltage environments.
• Low standby power: Sleep mode reduces static current by up to 100×, aiding power-sensitive applications.
• Compact packaging: 100‑ball LFBGA/CSPBGA option provides high I/O density in an 8×8 mm footprint for space-constrained boards.
