Programmable spread spectrum signaling over a pin of an integrated circuit device

An apparatus, comprising:

• a sensor;
• a printed circuit board having a plurality of traces;
• a first integrated circuit chip connected to the traces;
• and
• a second integrated circuit chip mounted on the printed circuit board and having a plurality of pins connected to the traces, the second integrated circuit chip having a first driver programmable to adjust a frequency spread spectrum signal driven onto a first pin, among the plurality of pins, wherein the apparatus is configured to program the first driver based at least in part on a measurement from the sensor.

A method, comprising:

• writing, in a register of an integrated circuit memory chip having a plurality of pins, a parameter representative of a spread spectrum sequence;
• receiving a read command in the integrated circuit memory chip;
• retrieving, responsive to the read command, data from one or more memory cells of the integrated circuit memory chip;
• and
• driving, by a driver connected to a pin, a spread spectrum signal representative of the data on the pin according to the parameter representative of the spread spectrum sequence.
