LCMXO256E-4T100C

The LCMXO256E-4T100C is a MachXO family FPGA offered in a 100-pin LQFP package designed for low-to-moderate density glue logic and system control tasks. It integrates non-volatile, instant-on configuration and delivers flexible I/O and logic resources tailored for bus interfacing, control logic, power-up sequencing and other system glue functions.

With 256 logic elements, up to 78 I/O pins, and a compact 100-LQFP (14 × 14 mm) footprint, this surface-mount device targets commercial designs requiring fast startup, field reconfiguration and low component count. The device operates over a supply range of 1.14 V to 1.26 V and a commercial temperature range of 0 °C to 85 °C.

Key Features

• Non-volatile, instant-on configuration  Single-chip, non-volatile architecture for rapid power-up without external configuration memory.
• In-field reconfiguration (TransFR™)  Supports in-system logic updates to modify functionality while the system remains operational.
• Low-power sleep mode  Sleep mode capability enables up to 100× static current reduction for power-sensitive applications.
• Logic resources  Provides 256 logic elements to implement glue logic, finite-state machines and control functions.
• I/O density  Up to 78 general-purpose I/Os in the 100-pin package to interface with buses, sensors and peripherals.
• Flexible packaging  100-LQFP package case with supplier device package listed as 100-TQFP (14×14 mm), optimized for surface-mount assembly.
• Power and temperature  Designed for a supply voltage range of 1.14 V to 1.26 V and commercial operating range of 0 °C to 85 °C.
• Design and system support  MachXO family features include single-chip configuration, background programming of non-volatile memory and JTAG programmability for in-system updates and testing.

Typical Applications

• Glue Logic and Bus Bridging  Implement address decoding, bus multiplexing and simple protocol bridging with compact logic resources and abundant I/O.
• System Control and Power Sequencing  Use instantaneous configuration and sleep mode to manage power-up sequences and low-power states in commercial products.
• User Interface and Peripheral Control  Drive displays, buttons and peripheral interfaces while consolidating discrete glue components into a single device.
• In-field Field Upgrades  Leverage TransFR reconfiguration to update control logic or add features without removing the device from the system.

Unique Advantages

• Single-chip, secure configuration: Eliminates external configuration memory and reduces system BOM while avoiding exposed bitstreams.
• Instant-on responsiveness: Powers up in microseconds to enable faster system availability and simplify startup sequencing.
• Field reprogrammability: In-field TransFR updates allow iterative feature enhancements and bug fixes without hardware changes.
• Power-efficient operation: Sleep mode provides substantial static current reduction for battery-assisted or low-power commercial designs.
• Compact surface-mount package: 100-LQFP (14×14 mm) footprint balances I/O count and board space for space-constrained designs.
