Preliminary Data Sheet
Table 15. I/O Specifications—All CPU Speeds (Sheet 1 of 2)
Notes:
1. Ethernet interface meets timing requirements as defined by IEEE 802.3 standard. Timing shown is with EMAC noise filter
selected.
2. For all interfaces, I/O H is specified at 2.4 V and I/O L is specified at 0.4 V.
3. Maximum skew between IIC output signals is 6ns.
4. Maximum skew between all SPI output signals is 3ns. All SPI inputs signals are latched with less than 4ns of skew between
channels.
5. Maximum skew between all PWM output signals is 3.75ns. All PWM input signals are latched with less than 2.5ns of skew
between channels.
