TCC76x
Specification Rev. 0.07
February 23, 2005
32-bit RISC Microprocessor for Digital Media Player
TCC76X VS. TCC72X
Preliminary
25-3
25.3 Differences in I/O Cell Characteristics
•
All the digital I/O cells except XIN and XTIN have wide operating voltage range (1.65V ~ 3.6V).
•
Programmable output buffer drive strength and pull-up resistors.
•
Due to I/O characteristics at low voltage levels (< 1.8V), tolerarant I/O cell was not used in the TCC76x.
Input voltage must not exceed VDDIO level.
•
Crystal oscillator input pins (XIN, XTIN) are dedicated 1.8V cells. Do not apply voltage over VDD_OSC
(Max. 1.95V) for these pins.
