Overview of LCMXO3L-4300C-6BG400I – MachXO3 FPGA, 4320 logic elements, 335 I/Os, 400‑LFBGA
The LCMXO3L-4300C-6BG400I is a MachXO3 family Field Programmable Gate Array from Lattice Semiconductor Corporation. It provides a flexible, non-volatile FPGA architecture with 4320 logic elements and 94,208 bits of embedded RAM for glue logic, I/O aggregation, and control functions.
With 335 available I/Os, on-chip hardened peripherals and configurable clocking, this industrial-grade device (‑40 °C to 100 °C) targets designs that need high I/O density, non-volatile configuration and robust system-level integration.
Key Features
- Core Logic 4320 logic elements organized into 540 logic blocks provide capacity for combinational and sequential logic, state machines and glue logic functions.
- Embedded Memory Approximately 94,208 bits of on-chip RAM (sysMEM) supporting single/dual/pseudo-dual port and FIFO modes for data buffering and small on-chip storage.
- I/O and Interface Up to 335 I/Os with pre‑engineered source-synchronous I/O and flexible I/O buffering to support a wide range of parallel and serial interfacing needs.
- Programmability and Configuration Non-volatile, multi-time programmable fabric with TransFR reconfiguration and user flash memory (UFM) for configuration and small data storage.
- Embedded Hardened IP Built-in hardened peripherals including I²C, SPI and timer/counter blocks to offload common functions from fabric logic.
- Clocking and Timing Flexible on-chip clocking with sysCLOCK PLLs and an on-chip oscillator to simplify timing architectures and reduce external components.
- Package and Environmental 400‑LFBGA (17×17) surface-mount package, industrial temperature grade (‑40 °C to 100 °C) and wide supply range (2.375 V to 3.465 V).
- System and Test IEEE‑1149.1 boundary-scan testability and configuration/testing features for easier board bring-up and diagnostics.
Typical Applications
- Industrial Control — Use the industrial temperature rating and 335 I/Os to implement sensor interfacing, motor control logic and I/O aggregation in factory and process-control equipment.
- Interface Bridging — High I/O count and flexible I/O buffering make the device suitable for protocol translation and bus bridging between disparate subsystems.
- Embedded System Glue Logic — 4320 logic elements and on-chip RAM enable consolidation of glue logic, state machines and small data buffers in consumer and industrial embedded designs.
- Peripheral Offload — Hardened I²C, SPI and timer/counter IP reduce fabric usage for common peripheral tasks, simplifying firmware and freeing logic resources.
Unique Advantages
- Non‑volatile, multi‑time programmable fabric: Retains configuration without external flash and supports in-system reprogramming for field updates and iterative development.
- High I/O density: 335 I/Os allow direct connection to numerous peripherals and buses, reducing the need for external I/O expanders.
- Integrated hardened peripherals: On-chip I²C, SPI and timers lower BOM and free programmable fabric for application‑specific logic.
- Flexible on‑chip clocking: sysCLOCK PLLs and an internal oscillator enable adaptable clock architectures with fewer external components.
- Industrial operating range: Rated for ‑40 °C to 100 °C, supporting deployment in harsh or temperature-variable environments.
- Compact, advanced packaging: 400‑LFBGA (17×17) surface-mount package provides high pin density in a compact footprint.
