General-Purpose I/O. 4 mA drive, TTL compatible I/O, 5 V
tolerant.
Reset (Active-Low). Schmitt trigger, TTL compatible input,
5 V tolerant.
Crystal Input (pclk). This input may be driven by either a
crystal or an external clock. If a crystal is used, connect it
between this pin and xtalout and connect the appropriately
valued capacitor from this pin to V
If an external clock is used, this is a 5 V tolerant CMOS
input with 50 MHz max input frequency.
Crystal Output Feedback. If a crystal is used, connect it
between this pin and xtalin and connect the appropriately
valued capacitor from this pin to V
used to drive xtalin, this pin must be left unconnected.
Buffered Clock Output. If enabled, pclk is output on this
pin. 8 mA drive, TTL compatible output. This pin is high
impedance if not enabled.
CKO Enable. Enable for buffered clock output. If cko is not
used, tie this enable pin low. Active-high, TTL compatible
input, 5 V tolerant.
No Connection. Reserved.
Power. 3.3 V. These pins should be properly
decoupled using 0.01 F or 0.1 F capacitors.
Ground.
Clock Oscillator Power. 3.3 V. This pin should
be properly decoupled using 0.01 F or 0.1 F
capacitors.
