Overview of LCMXO256C-3T100C – MachXO Field Programmable Gate Array (FPGA) IC, 256 logic elements, 78 I/Os, 100-LQFP
The LCMXO256C-3T100C is a MachXO family field programmable gate array (FPGA) in a 100-pin LQFP surface-mount package. It combines non-volatile configuration, a compact logic fabric and flexible I/O to address glue logic, bus bridging, power-up control and general system control applications.
Designed for commercial-grade applications, this device provides instant-on non-volatile operation with flexible I/O options and a compact 14×14 mm 100-pin package, making it suitable for space- and cost-constrained embedded designs.
Key Features
- Core Logic — 256 logic elements (LUT4-based architecture) providing a compact programmable fabric for glue logic, control paths and interface adaptation.
- I/O Density & Flexibility — 78 user I/Os in the 100-pin package; programmable I/O buffers support a broad range of signaling standards as described in the MachXO family documentation.
- Non-volatile, Instant-On Operation — MachXO family features include single-chip non-volatile configuration and instant-on behavior, eliminating the need for external configuration memory.
- Memory — Family-level architecture provides distributed RAM resources; LCMXO256 is specified with distributed RAM (family table shows 2.0 Kbits) and no embedded EBR SRAM blocks for this density point.
- Power and Voltage — Single-device operation across the specified voltage supply range of 1.71 V to 3.465 V; supports low-power modes described in the MachXO family documentation, including a sleep mode for reduced static current.
- Package & Mounting — 100-LQFP (14×14 mm) surface-mount package, ideal for PCB designs requiring a compact TQFP footprint.
- Commercial Temperature Grade — Rated for 0 °C to 85 °C operation for standard commercial applications.
- Standards & Tooling — MachXO family devices are supported by Lattice design flows (ispLEVER and related tools) and system-level features such as IEEE 1149.1 boundary scan and IEEE 1532 in-system programming (family documentation).
Typical Applications
- Glue Logic & System Control — Implement glue logic, power sequencing and control state machines with compact, non-volatile programmable logic.
- Bus Bridging & Interface Adaptation — Bridge or adapt between legacy and modern buses, leveraging flexible programmable I/O and a concentrated logic array.
- Power-Up and Reset Management — Centralize power-up sequencing and reset distribution on a single non-volatile device to simplify system initialization.
- User Interface Control — Handle button scanning, LED control and simple HMI tasks with low-pin-count, instant-on programmable logic.
Unique Advantages
- Single-Chip Non-Volatile Configuration: Eliminates external configuration memory and enables instant-on operation for faster system availability.
- Compact, High Pin-to-Logic Ratio: 256 logic elements with 78 I/Os in a 100-pin LQFP footprint simplifies PCB layout for space-constrained systems.
- Flexible I/O Signaling: Programmable I/O buffers documented for a wide range of standard interfaces, reducing the need for external level shifters and interface components.
- Sleep Mode for Low Static Current: Family-level sleep mode support enables significant static current reduction for lower power standby states.
- Commercial Temperature and RoHS Compliance: Rated 0 °C to 85 °C and RoHS compliant for mainstream embedded and consumer electronics designs.
- Design Ecosystem Support: Supported by the MachXO family design tools and flows for synthesis, place-and-route and in-system programming.
