156 / 193 page  ST72325 156/193 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.
