The device provides up to 286 user I\/O pins with support for LVCMOS, LVTTL, and LVDS I\/O standards. Hardened I2C and SPI interfaces allow in-system configuration access without logic resources. The dual-boot feature enables fail-safe firmware updates by maintaining two configuration images. The device operates from a 1.2V core supply with 3.3V I\/O, and is configured from external SPI flash. The MachXO3 family targets glue logic, bus bridging, and control applications where low power and instant-on capability are required.","working_principle":"The LCMXO3LF-4300C-5BG400C uses Lattice's low-power FPGA architecture. (1) LUT4: Each logic element contains a 4-input look-up table (LUT4) and a flip-flop, implementing any 4-input combinational function plus sequential storage. (2) Distributed RAM: LUT4 elements can be configured as 16x1 distributed RAM for small memory requirements. (3) EBR: Embedded Block RAM provides 18kb per block of dual-port synchronous RAM for larger data buffers. (4) PLL: Two phase-locked loops multiply, divide, and phase-shift the input clock for system clock generation. (5) Configuration: The device loads its configuration from an external SPI flash on power-up. Dual-boot maintains two images and falls back to the previous image if the new image is corrupted. (6) Hardened Interfaces: Dedicated I2C and SPI controllers are accessible during configuration for system management without consuming LUT resources.","pin_description":"
