• Embedded Memory  Approximately 442,368 bits of embedded memory (~0.44 Mbits) in sysMEM blocks, supporting single/dual-port and FIFO modes for buffering and local storage.
• I/O and Interfaces  206 general-purpose I/O pins with programmable I/O cells and pre‑engineered source-synchronous I/O capabilities for flexible interface implementation.
• Configuration and Non‑Volatility  Non-volatile, multi-time programmable configuration with TransFR reconfiguration and on-chip user flash memory (UFM) described in the MachXO3 family datasheet.
• Clocking and Timing  Flexible on-chip clocking including sysCLOCK Phase Locked Loops (PLLs) and clock distribution network for system timing management.
• Embedded Hardened IP  Hardened peripherals such as I²C and SPI IP cores, timers/counters, and other system level IP documented in the family datasheet to accelerate common design tasks.
• On-Chip Utilities  On-chip oscillator, programmable I/O buffers, and support for hot-socketing and boundary-scan testability as outlined in the MachXO3 datasheet.
• Power and Packaging  Operates from a 2.375 V to 3.465 V supply range, supplied in a 256‑LFBGA (256‑CABGA, 14×14) surface-mount package for compact board-level integration.
• Industrial Grade  Qualified for an operating temperature range of −40 °C to 100 °C and RoHS compliant for industrial deployments.

Typical Applications

• Industrial Control  Use the device’s industrial temperature rating, abundant I/O and embedded logic to implement sensor aggregation, motor control interfaces, and machine control glue logic.
• Interface Bridging  Leverage the hardened I²C/SPI cores and flexible I/O cells to bridge disparate peripheral buses and implement protocol converters.
• System Glue and Management  Deploy the MachXO3 device as board-level glue: manage reset sequencing, power monitoring, and custom control functions using on-chip timers and UFM.
• User Interface and Peripheral Control  Implement display drivers, GPIO expansion and human‑machine interface logic making use of plentiful I/O and embedded memory for buffering.

Unique Advantages

• Highly integrated programmable fabric: Combines ~9,400 logic elements with embedded RAM and hardened IP to reduce external components and simplify BOM.
