Frequently asked questions
What is the closest pin-compatible alternative to LPC1115FET48/303Y?
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.
What is the LPC1115FET48/303Y's core speed?
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.
