120 MHz clock on this Cortex-M3 core. Runs a lightweight RTOS, a TCP/IP stack, and a display update loop without external memory.
The 96 KB SRAM is the tighter resource: if you plan to buffer multiple Ethernet frames or run a full frame buffer for a QVGA display, you will want to allocate an external SDRAM or SRAM on the EBI/EMI bus.
Listed as Active in production.
The LPC1788FBD144,551 runs at 120 MHz on its ARM Cortex-M3 core.
The LPC1788 family includes multiple Flash and SRAM density options in the same 144-LQFP footprint. A higher-density sibling (e.g., LPC1789 with 512 KB Flash and 96 KB SRAM) is pin-compatible and can be substituted without a PCB change, provided the application fits within the same supply and temperature ratings.
