VDD (3.3V) The I/O power pins (VDD) should
AB17 D11 be connected to a well-decoupled +3.3 V DC
D16 D4
supply. These pins include the VDDO pins for
E1 F20 L1 the switching, as well as the VDDQ for the
L19 R21
R4 V2
quiet power pins.

Notes on Pin Description:
• All S/UNI-IMA-8 I/O present minimum capacitive loading and operate at TTL
logic levels and can tolerate 5.0V levels.
• Inputs RSTB, ALE, TCK, TMS, TDI , TRSTB, TSCLK, CTSCLK, RSCLK,
RSDATA, an OE have internal pull-up resistors.
• Power to the VDD (3.3V) pins should be applied before power to the VDDI
(1.8V) pins is applied. Similarly, power to the VDDI (1.8V) pins should be
removed before power to the VDD (3.3V) pins is removed.
