Key Features

• Logic Capacity 640 logic elements suitable for glue logic, protocol bridging, and small control functions.
• On‑chip Memory 65,536 bits of RAM (approximately 64 Kbits) for embedded block RAM needs such as FIFOs, small buffers, or lookup tables.
• I/O Density 100 user I/Os in a single device, enabling multi‑interface and board interconnect tasks.
• Non‑volatile, Multi‑time Programmable Configuration Series‑level capability to retain configuration without external configuration memory and support multiple reprogram cycles.
• Flexible I/O and Clocking MachXO3 family features include source synchronous I/O, flexible on‑chip clocking and PLLs for system timing and interfacing requirements.
• Hardened Peripherals Family datasheet documents embedded hardened IP such as I2C and SPI controllers and a timer/counter block for common system functions.
• Advanced Packaging 121‑VFBGA (6 × 6 mm supplier package) surface‑mount package for compact board layouts.
• Industrial Temperature Range Rated for operation from −40 °C to 100 °C for deployment in industrial environments.
• Low Voltage Core Core supply specified between 1.14 V and 1.26 V for compatibility with low‑voltage system rails.
• System-Level Support MachXO3 family features documented in the datasheet include on‑chip oscillator, user flash memory (UFM), standby and power saving modes, and hot‑socketing behavior.
• Standards and Testing Family documentation includes configuration and testing support such as IEEE 1149.1‑compliant boundary scan testability.
• RoHS Compliant Meets RoHS environmental requirements.

Typical Applications

• Industrial Control Use the device’s industrial temperature rating, compact package and I/O density to implement board‑level control, interface logic and local supervision functions.
• Interface and Protocol Bridging Hardened I2C/SPI IP and flexible I/O/clocking make the device suitable for bridging peripherals and handling interface conversions between subsystems.
• Embedded System Glue Logic Small FPGA fabric and on‑chip RAM are ideal for consolidating discrete logic, implementing state machines, and managing peripheral sequencing.

Unique Advantages

• Compact, production‑ready package: The 121‑VFBGA CSPBGA package delivers 100 I/Os and dense functionality in a 6 × 6 mm footprint for space‑constrained boards.
• Non‑volatile configuration: On‑device multi‑time programmable configuration removes the need for external configuration flash, simplifying BOM and board design.
• Industrial robustness: Rated for −40 °C to 100 °C operation, enabling deployment in harsh industrial environments where extended temperature range is required.
• System integration: Embedded memory, hardened peripheral IP and on‑chip clocking reduce the number of external components required for common embedded tasks.
• Low core voltage operation: Narrow core supply range (1.14 V–1.26 V) supports low‑power system architectures and consistent power sequencing.
