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.
