ARM Cortex-M0 at 50 MHz — what it means for the BOM
The 28 general-purpose I/O lines and the 8-channel 10-bit ADC give it enough pinout for a handful of digital inputs, a few analog channels, and one or two serial buses — typical for a small control board or a human-machine interface panel that talks Modbus over UART.
On-chip resources and peripheral set
The internal oscillator eliminates the need for an external crystal in many applications, saving two pins and a couple of passive components. Brown-out detect, POR, and a watchdog timer are built in — no external supervisor IC required for basic reset and voltage monitoring. The UART/USART, SPI, and I²C interfaces cover the common serial protocols for sensor readout, display communication, or programming through a bootloader.
Lifecycle and sourcing
The LPC1113FHN33/302551 carries an Active product status. No end-of-life notice or last-time-buy window is on record. For volume production, the part is sourced and quoted to order through independent distribution; availability and current pricing are confirmed at quote time. The base number LPC1113 covers multiple Flash and RAM density options in the same package, so if a future BOM revision needs more memory, a pin-compatible sibling in the LPC111x family can be swapped without a PCB change.
