EMC CHARACTERISTICS (Cont’d)
12.7.2 Electro Magnetic Interference (EMI)
Based on a simple application running on the
product (toggling 2 LEDs through the I/O ports),
the product is monitored in terms of emission. This
emission test is in line with the norm SAE J 1752/
3 which specifies the board and the loading of
each pin.
Notes:
1. Data based on characterization results, not tested in production.
2. Refer to Application Note AN1709 for data on other package types.
