3. ELECTRICAL SPECIFICATIONS

3.1 Buffer List

• 2.5 V oscillator interface

XIN, XOUT

• 3.3 V input buffer

TEST, SCAN

• 3.3 V schmitt input buffer

• 3.3 V IOL = 3 mA bi-directional buffer with input enable (OR-type)

SDA, SCL, DPC (GPIO5), CMB_STATE (GPIO6), CMB_BSY (GPIO7)

• 5 V schmitt input buffer

VBUS

• 5 V IOL = 6 mA bi-directional buffer with input enable (OR-type)

IDED(15:0), IDEINT, IDEIORDY, IDEDRQ, IDECS(1:0)B, IDEA(2:0), IDEDAKB, IDEIORB, IDEIOWB,

IDERSTB

• USB interface

DP, DM, RSDP, RSDM, RREF, RPU

Remark “5 V” refers to a 3.3 V buffer with 5-V tolerant circuit. Therefore, it is possible to have a 5-V connection for

an external bus, but the output level will be only up to 3.3 V, which is the VDD33 voltage.
