It handles UART polling loops, SPI sensor reads, and simple state machines without breaking a sweat, but it is not the part for heavy DSP or floating-point math — that would push you to a Cortex-M4 or M7 part with a higher clock and hardware FPU. For a Modbus RTU slave node or a basic I/O expander with a local display, 50 MHz is ample headroom. ## Memory sizing — 64 KB Flash, 8 KB RAM 64 KB of Flash and 8 KB of RAM is the typical sweet spot for a single-protocol field device or a sensor hub that runs a small RTOS. The Flash holds the firmware image plus a modest lookup table; the RAM covers stack, heap, and a few hundred bytes of buffered I/O.","metaTitle":"NXP LPC1115FBD48/303,1 ARM Cortex-M0 MCU, 50 MHz, 64 KB Flash","metaDescription":"NXP LPC1115FBD48/303,1 32-bit ARM Cortex-M0 MCU, 50 MHz, 64 KB Flash, 8 KB RAM, 42 I/O, -40 to 85 °C, 48-LQFP.
