Overview of LCMXO640E-4BN256I – MachXO FPGA, 640 logic elements, 159 I/Os, 256-LFBGA
The LCMXO640E-4BN256I is a MachXO family Field Programmable Gate Array (FPGA) optimized for glue logic, bus interfacing and control functions. It combines non-volatile, instant-on operation with a LUT-based logic fabric suitable for low- to mid-density control and interfacing tasks.
Built for industrial applications, the device offers 640 logic elements, up to 159 user I/Os in a 256-ball LFBGA/CSPBGA package, instant-on single-chip configuration and features for in-field reconfiguration and low-power standby.
Key Features
- Core Logic – 640 logic elements (LUT4s) providing flexible combinational and sequential logic capacity for glue logic and control functions.
- Logic Blocks – 80 logic blocks supporting structured routing and placement of logic networks.
- I/O Density – 159 I/Os available in the 256-ball package to support broad interfacing and bus bridging requirements.
- Non-volatile, Instant-on – Single-chip configuration with no external configuration memory required and instant-on behavior at power-up as described in the MachXO family data.
- In-field Reconfiguration – Supports background programming and TransFR™ reconfiguration for updating SRAM-based logic while the system operates; programming and configuration supported via JTAG.
- Embedded Memory – Family-level distributed RAM support (MachXO640 family documented with approximately 6.1 Kbits of distributed RAM).
- Power Management – Sleep mode capability for significant static current reduction (up to 100× reduction described for the family).
- Package & Mounting – Surface-mount 256-LFBGA (CSPBGA) / supplier device package 256-CABGA (14×14 mm) for high pin-count, compact board layouts.
- Voltage & Temperature – Operates with supply in the range 1.14 V to 1.26 V and an industrial operating temperature range of −40°C to 100°C.
- Standards & Tools – MachXO family supports IEEE 1149.1 boundary-scan and is compatible with Lattice ispLEVER design tools for synthesis, place-and-route and timing verification.
Typical Applications
- Glue Logic & Bus Bridging – Implement address decoding, bus interfacing and protocol translation with compact, single-chip logic and abundant I/O.
- Power-up & System Control – Instant-on, non-volatile configuration and low-power sleep modes make the device suited for power sequencing, reset control and supervisory functions.
- Control & State Machines – Use the LUT-based logic and distributed RAM to implement control logic, finite-state machines and event sequencing.
- Peripheral & Sensor Interfaces – High I/O count and flexible I/O buffer support enable direct interfacing to a variety of peripherals and sensors for embedded applications.
Unique Advantages
- Single-chip, non-volatile solution: Eliminates the need for external configuration memory and enables microsecond-class power-up readiness.
- In-field update capability: TransFR™ reconfiguration and JTAG-based programming allow logic updates while the system remains operational, reducing downtime for field revisions.
- Industrial temperature range: Rated for −40°C to 100°C operation, supporting deployment in industrial environments.
- High I/O in a compact package: 159 I/Os in a 256-ball LFBGA footprint provide a high pin-to-area ratio for complex interfacing without large board area.
- Low-power standby: Sleep mode yields major static current reductions for energy-conscious designs.
- Design and debug support: Boundary-scan (IEEE 1149.1) and compatibility with ispLEVER tools streamline development and verification.
