Pin Descriptions
Table 1-2 describes the SX device pins. For each pin, the table shows the pin type (input, output, or
power), the input voltage levels (TTL, CMOS, or Schmitt trigger), and the pin function. Note that not
all of these pins are available on all the devices. For example, some devices have fewer I/O pins. Also
note that only the core functions of the pins are shown in the table. Some pins have additional functions
in certain SX devices.
The following abbreviations are used in the table:
I = device input
O = device output
I/O = bidirectional I/O pin
P = power supply pin
NA = not applicable
TTL = TTL input levels
CMOS = CMOS input levels
ST = Schmitt trigger input
MIWU = Multi-Input Wakeup
