Overview of LCMXO256C-4T100I – MachXO FPGA, 256 Logic Elements, 78 I/O, 100-LQFP
The LCMXO256C-4T100I is a MachXO family Field Programmable Gate Array (FPGA) IC from Lattice Semiconductor Corporation designed for industrial applications. It combines non-volatile, instant-on architecture with a compact 100-pin LQFP package to address glue logic, bus interfacing, power-up control and general control-logic functions.
With 256 logic elements distributed across 32 logic blocks and up to 78 user I/Os, the device targets low-to-moderate density system tasks where single-chip integration, fast startup and flexible I/O are important.
Key Features
- Core Logic 256 logic elements (LUTs) implemented across 32 logic blocks for flexible combinational and control logic.
- I/O Capacity Up to 78 user I/Os in a 100-pin package to support a wide range of peripheral and bus interfaces.
- Memory Distributed on-chip RAM available as part of the MachXO family architecture (family datasheet lists approximately 2.0 Kbits distributed RAM for the 256-device class).
- Non‑volatile, Instant‑on Configuration MachXO family architecture provides single-chip, non-volatile configuration for rapid power-up without external configuration memory.
- In-field Reconfiguration Family-level features include background programming and TransFR™ reconfiguration for updating logic while the system operates.
- Low‑power Modes Sleep-mode capability (family-level) enables significant static current reduction for power-sensitive designs.
- Voltage Range Operation across a broad supply range from 1.71 V to 3.465 V to accommodate multiple I/O and core voltage schemes.
- Package & Mounting 100-LQFP (supplier package: 100-TQFP, 14×14 mm), surface-mount package suitable for compact PCB layouts.
- Industrial Temperature Grade Rated for operation from -40°C to 100°C to meet industrial-environment requirements.
- RoHS Compliant Lead-free, RoHS-compliant device packaging.
Typical Applications
- Glue Logic and System Control Implement board-level control, reset sequencing and power-up sequencing with a single non-volatile device.
- Bus Bridging and Interfacing Bridge or adapt between buses and peripheral interfaces using flexible I/O and programmable logic.
- Power Management and Sequencing Integrate power-up control, sequencing and monitoring functions that require deterministic, instant-on behavior.
- Peripheral and User Interface Control Manage button scanning, LED drivers, and other human‑machine interfaces with modest logic and multiple I/Os.
Unique Advantages
- Single‑chip, non‑volatile configuration: Eliminates the need for external configuration memory and enables fast, deterministic startup.
- Compact package with generous I/O: 78 available I/Os in a 100‑pin LQFP give a strong pin-to-logic ratio for small form-factor designs.
- Industrial temperature support: -40°C to 100°C rating supports robust operation in harsh environments.
- In-field update capability: Family-level TransFR and background programming support allow logic updates without full system downtime.
- Wide supply voltage window: 1.71 V to 3.465 V operation enables compatibility with multiple system voltage domains.
- RoHS-compliant packaging: Meets lead-free manufacturing requirements for modern production flows.
Why Choose LCMXO256C-4T100I?
