The LPC11E11FHN33/101,: 32-bit ARM Cortex-M0 MCU running at 50 MHz, with 8 KB Flash, 4 KB RAM, and 512 B EEPROM on-chip. 28 I/O lines and an 8-channel 10-bit ADC cover sensor-read and switch-debounce tasks.
Connectivity covers I²C, SPI, SSP, and UART, plus Microwire and SSI compatibility. The 8×10-bit ADC samples at moderate rates for voltage/current monitoring or potentiometer feedback.
Listed as Active. No last-time-buy or phase-out notice.
The ARM Cortex-M0 core runs at 50 MHz. That throughput handles typical control-loop and protocol-processing tasks for a small embedded node.
Yes, it has 512 bytes of on-chip EEPROM. This eliminates the need for an external serial EEPROM for calibration data or small parameter tables.
