I'm working on a new "light industrial" product based around an MSP430F436.
The product is a battery / external powered data logger which sleeps waking
every 1/2ms or so to check some sensors. It is used for data logging only -
ie non-critical applications.
Has anyone had any experience EMC testing similar MSP430 based designs?
Other facets of the design include:
*LCD - non muxed updating around 32Hz, always on.
*Serial interface accessed intermittently
*Micro clock xtal = 32768 Hz
*Linear regulator power supply.
*The enclosure is a mix of metal/plastic and is unlikely to be grounded.
*Very little else in the way of clocked logic, no oscillators or high
current switching etc.
My thoughts are that a 2 layer board with plenty of ground plane either side
etc should be sufficient.
Any comments advice welcome!
thanks
