LPC1110/11/12/13/14/15
32-bit ARM Cortex-M0 microcontroller
[1] Typical ratings are not guaranteed. The values listed are at room temperature (25 C), nominal supply
voltages.
[2] The typical frequency spread over processing and temperature (T
amb
= 40 C to +105 C) is 40 %.
[3] See the LPC111x user manual.
