1. Data in Typical column was characterized at 5.0 V, 25 °C or is typical recommended value.
2. The current varies with TSI configuration and capacity of touch electrode. Please refer toTSI electrical specifications.
3. LVD is periodically woken up from stop3 by 5% duty cycle. The period is equal to or less than 2 ms.
5.1.3 EMC performance
Electromagnetic compatibility (EMC) performance is highly dependant on the
environment in which the MCU resides. Board design and layout, circuit topology
choices, location and characteristics of external components as well as MCU software
operation all play a significant role in EMC performance. The system designer should
consult Freescale applications notes such as AN2321, AN1050, AN1263, AN2764, and
AN1259 for advice and guidance specifically targeted at optimizing EMC performance.
