5 – Module Main Components Description
4.1 Micro-controller LPC1224
The module’s micro-controller is a
LPC1224 from NXP
5
. The LPC1224 version used on the module is the
LPC1224FBD48/101. All LPC1224 have an ARM Cortex-M0 core running at up to 45 MHz.
The module uses the internal 12 MHz RC Oscillator as main clock. Its 1% accuracy is suitable for most applica-
tions.
