100 MHz Cortex-M3 with Ethernet, CAN, and USB OTG
The NXP LPC1758FBD80K is a 32-bit ARM Cortex-M3 microcontroller running at 100 MHz, with 512 KB of Flash program memory and 64 KB of RAM. It packs Ethernet, CAN, and USB OTG connectivity alongside I²C, SPI, UART, and IrDA interfaces — enough peripheral set to serve as the main controller in an industrial gateway, a motor-drive node, or a networked sensor hub. The 80-LQFP package (12x12 mm) keeps board area manageable while still offering 52 general-purpose I/O lines.
What the 100 MHz core and 512 KB Flash mean for your BOM
The 100 MHz clock on a Cortex-M3 is enough to run a lightweight TCP/IP stack, handle CAN message filtering, and service USB OTG transfers without a separate protocol chip. The 512 KB Flash gives room for a bootloader, application firmware, and a small file system for configuration logs — no external SPI Flash needed for many designs. The 64 KB RAM handles a couple of moderate-sized packet buffers and the usual stack/heap; if your application needs large frame buffers or heavy data logging, plan for external SRAM or SDRAM.
Supply range is 2.4 V to 3.6 V.
