LCMXO640C-5BN256C

The LCMXO640C-5BN256C is a MachXO family FPGA from Lattice Semiconductor Corporation that combines non-volatile instant-on behavior with FPGA-style LUT-based logic. The device provides approximately 640 logic elements and up to 159 I/Os in a 256-ball LFBGA/CSPBGA package (14 × 14 mm), making it suitable for glue logic, bus bridging and general control functions in commercial applications.

Designed for single-chip configuration with no external configuration memory required, this MachXO device targets applications that need fast power-up, reconfigurability, and flexible I/O support across a broad supply range (1.71 V to 3.465 V).

Key Features

• Core Logic  Approximately 640 LUT-based logic elements provide the programmable fabric for implementing glue logic, interface glue, and control functions.
• I/O Density  Up to 159 I/Os in a 256-ball LFBGA/CSPBGA package, enabling high pin-to-pin connectivity for bus and peripheral interfacing.
• Non-volatile, Instant-on  Single-chip non-volatile configuration (no external configuration memory required) enables fast power-up and secure device configuration.
• Reconfiguration  Supports in-field reconfiguration capabilities including background programming and TransFR™ reconfiguration for updates while the system operates.
• Memory  Distributed on-chip memory available as part of the MachXO640 family architecture to support small FIFOs and local state storage.
• Flexible sysIO™ Buffer  Programmable I/O buffer support for multiple standards (family supports LVCMOS at common core voltages and differential interfaces listed in the MachXO family data sheet).
• Power and Temperature  Commercial-grade device with operating temperature range 0 °C to 85 °C and supply range of 1.71 V to 3.465 V.
• Package  256-ball LFBGA / CSPBGA (14 × 14 mm) package offering a compact, surface-mount footprint for space-constrained board designs.
• Low-Power Mode  Sleep mode support that can significantly reduce static current draw for power-sensitive applications.
• Standards & Test  Supports JTAG-based programming and in-system programming standards as described for the MachXO family.

Typical Applications

• Glue Logic  Implement bus adapters, address decoding and interconnect glue in systems where compact, instant-on logic is required.
• Bus Bridging & Interfacing  Serve as a protocol adapter or level shifter between disparate buses and peripherals using the device’s flexible I/O and high pin count.
• Power-up Control  Manage power sequencing and supervisory control with fast power-up behavior and onboard configuration.
• Control Logic  Implement board-level control, state machines, and peripheral control functions in commercial electronic products.
• Field-updatable Logic  Enable in-field logic updates and background non-volatile programming for deployed systems that require periodic feature updates.

Unique Advantages

• Single-chip, non-volatile configuration: Eliminates the need for external configuration memory and simplifies BOM and board routing.
• Instant-on operation: Powers up in microseconds (as described for the MachXO family), reducing system startup delays and simplifying system-level power sequencing.
• High I/O-to-logic ratio: Up to 159 I/Os paired with approximately 640 logic elements provides dense interfacing capability relative to the logic capacity.
• Flexible in-field updates: Background programming and TransFR reconfiguration support allow safe updates to non-volatile logic while systems remain operational.
• Compact BGA footprint: 256-ball LFBGA/CSPBGA (14 × 14 mm) package delivers high pin count in a small surface-mount form factor for space-constrained designs.
• Commercial temperature and supply flexibility: Operates from 1.71 V to 3.465 V across a 0 °C to 85 °C commercial temperature range, fitting many standard embedded applications.
