Product details

The LPC11U35FHI33/501Y: 32-bit ARM Cortex-M0 MCU runs at 50 MHz with 64 KB Flash and 12 KB RAM. 4 KB EEPROM stores calibration data without external serial EEPROM. 50 MHz core clock handles control loops and capacitive touch polling. 8-channel 10-bit ADC covers basic analog sensing.

The 64 KB Flash and 12 KB RAM place this MCU in the mid-range of the LPC11Uxx family. It has enough code space for a USB CDC or HID stack plus a modest application loop, but not for a full TCP/IP stack with a web server. The 4 KB EEPROM is a genuine differentiator — it lets you store calibration or serial-number data that survives a firmware update without wearing the Flash.

Integration note — USB and power

The Brown-out Detect and POR circuits mean no external supervisor IC is needed for a basic reset. The WDT can be configured in software to guard against firmware hangs. These peripherals reduce the BOM count for a simple controller board.

Frequently asked questions

What is LPC11U35FHI33/501Y's core speed?

The LPC11U35FHI33/501Y runs at 50 MHz on a 32-bit ARM Cortex-M0 core. That clock rate is suitable for control loops, USB polling, and serial protocol handling, but not for heavy DSP or video processing.
