[1]
Parameters are valid over operating temperature range unless otherwise specified.
[2]
Typical values valid for EMC pads set to fast slew rate: VDD_EMC = 1.8 V, VDD_CORE = 1.2 V or slower slew rate: VDD_EMC = 3.3 V,
VDD_CORE = 1.2 V (see SDRAMCLK_CTRL register in the
LPC32x0 User manual
).
[3]
All min or max values valid for EMC pads set to fast slew rate: VDD_EMC = 1.8 V, VDD_CORE = 1.2 V or slower slew rate: VDD_EMC
= 3.3 V, VDD_CORE = 1.2 V.
