LPC15xx
32-bit ARM Cortex-M3 microcontroller
[1] C
L
= 10 pF; results from measurements on silicon samples over process corners and over the full temperature range T
amb
= -40 C to
+105 C.
[2] Input hysteresis is relative to the reference input channel and is software programmable.

DDA
= 3.0 V. DLY = 0x0 in the analog comparator CTRL register for shortest propagation delay setting. See the LPC15xx
user manual UM10736.
