Product details

The NXP LPC11U66JBD48E is a 32-bit ARM Cortex-M0+ MCU clocked at 50 MHz, with 64 KB Flash, 12 KB SRAM, and 4 KB EEPROM on-chip. It integrates a USB full-speed device controller alongside I²C, SPI, UART, and SSP serial interfaces, making it a single-chip solution for USB-enabled control and sensor-interface applications in industrial and consumer equipment. The 34 general-purpose I/O lines and 8-channel 12-bit ADC cover typical mixed-signal monitoring and actuator-drive needs without external glue logic.

Supply range is 2.4 V to 3.6 V.

No end-of-life notice or successor part is cited in the record.
