32 KB Flash and 10 KB SRAM support a single-protocol stack. The 4 KB EEPROM stores calibration constants without an external part.
40 I/O lines in a 48-LQFP support a parallel LCD interface and keypad matrix. Connectivity includes I²C, SPI, UART/USART, Microwire, and SSI.
The LPC11Exx family includes pin-compatible density variants; the 64 KB Flash version (LPC11E14FBD64/401) shares the same 48-LQFP footprint and peripheral set, offering a direct upgrade path without board changes.
The listed core speed is 50 MHz, which is the maximum clock for the ARM Cortex-M0 core on this device.
The part is ROHS3 compliant. For REACH, UL, or IEC declarations, the manufacturer's compliance documentation is available through the standard product-change-notification process; request the specific certificate at quote time.
