The 50 MHz core delivers enough throughput for 8-channel 10-bit ADC sampling and UART/I²C/SPI peripheral handling without stalling the main loop. The internal oscillator keeps the BOM count low, though an external crystal can be added for tighter timing on the serial buses.
Rated for -40 to 85 °C ambient. Supply range 1.8 to 3.6 V.
Within the LPC1100XL series, other 48-TFBGA variants with the same pinout but different Flash/RAM densities (e.g., LPC1114 with 32 KB Flash) are footprint-compatible. Verify the exact memory sizing and peripheral set against the application before substituting.
The listed core speed is 50 MHz, driven by the ARM Cortex-M0 processor. This is the maximum clock rate; the internal oscillator or an external crystal can be used to reach it.
