The NXP LPC11U66JBD48551 is a 32-bit ARM Cortex-M0+ microcontroller from the LPC11Uxx series, clocked at 50 MHz.
At 50 MHz the Cortex-M0+ executes most single-cycle instructions. The 12 KB of RAM limits buffer-heavy applications.
Yes, the LPC11U66JBD48551 includes a USB 2.0 full-speed device controller as part of its connectivity block, alongside I²C, SPI, SSP, and UART interfaces.
The supply range is 2.4 V to 3.6 V on VDD/VDDIO, with a separate 3.3 V supply for the USB transceiver.
64 KB of Flash program memory, organized as 64K x 8 bits.
The 48-LQFP package provides 34 general-purpose I/O pins, with dedicated pins for USB D+/D-, the 8-channel 12-bit ADC inputs, and serial interface signals. The full pin assignment is documented in the NXP LPC11U6x user manual.
