[1] Typical ratings are not guaranteed. The values listed are for room temperature (25 C), nominal supply voltages.
[2] Attempting to program below 2.7 V will result in unpredictable results and the part might enter an unrecoverable state.
[3] The LPC5460x/61x operates at CPU frequencies of up to 180 MHz. The LPC54628 operates at CPU frequencies of up to 220 MHz.
