LCMXO3L-6900C-5BG256C

The LCMXO3L-6900C-5BG256C is a MachXO3 family FPGA from Lattice Semiconductor Corporation. It provides a non-volatile, multi-time programmable logic fabric with on-chip embedded memory and a broad set of system-level functions aimed at board-level control, interface bridging and glue-logic applications in commercial electronic products.

This device balances integration and flexibility with 6,864 logic elements, approximately 245,760 bits (≈0.246 Mbits) of embedded RAM, and 206 user I/O in a 256-lead LFBGA package. It is designed for surface-mount assembly and operates from a 2.375 V to 3.465 V supply over a commercial temperature range of 0 °C to 85 °C.

Key Features

• Logic Capacity — Approximately 6,864 logic elements suitable for glue logic, interface control and moderate-density processing tasks.
• Embedded Memory — Approximately 245,760 bits (≈0.246 Mbits) of on-chip RAM for buffering, FIFOs and small data stores; documented sysMEM support in the MachXO3 family.
• I/O and Interface — 206 user I/O pins with flexible, programmable I/O cells and pre-engineered source-synchronous I/O blocks to simplify interface implementation.
• Non-volatile Configuration — Multi-time programmable, non-volatile configuration for persistent system logic without requiring external configuration flash.
• Clocking and Timing — Flexible on-chip clocking including PLL support as described in the MachXO3 family documentation for system timing and clock-domain management.
• Embedded IP and Peripherals — Hardened IP functions referenced in the family datasheet, including I²C, SPI, timers/counters and on-chip oscillator for common peripheral needs.
• Package & Mounting — 256‑lead LFBGA package (supplier device package: 256‑CABGA 14×14), surface-mount for compact board-level integration.
• Power & Environmental — Supply range 2.375 V to 3.465 V and commercial operating temperature range of 0 °C to 85 °C; RoHS compliant.

Typical Applications

• Interface Bridging and Glue Logic — Use the 206 I/O and flexible I/O cells to implement level translation, protocol adaptation and board-level interface consolidation.
• Peripheral and Sensor Aggregation — Combine embedded I/O, timers and hardened serial IP (I²C/SPI) to collect, pre-process and forward sensor or peripheral data.
• Control and System Management — Implement system control, configuration management and small state machines using non-volatile configuration and built-in timers.
• Display and User Interface Control — Drive and manage user interfaces or small displays where moderate logic density and multiple I/O are required.

Unique Advantages

• Non-volatile, Multi-time Programmable Configuration: Preserve system logic without external configuration memory and allow field updates when needed.
• Integrated Peripheral IP: Hardened I²C, SPI and timer/counter IP reduce design effort and decrease bill-of-materials compared to discrete implementations.
• Compact, High-I/O Package: 256‑lead LFBGA with 206 I/O provides a high pin-count solution in a compact 14×14 form factor for space-constrained boards.
• Flexible On-chip Clocking: Built-in PLLs and clocking resources support multiple clock domains and timing topologies documented for the MachXO3 family.
• Commercial-grade Fit: Commercial temperature rating (0 °C to 85 °C) and RoHS compliance align with standard commercial electronics manufacturing and environmental requirements.
