Pin Characteristics

Table 3 describes the characteristics for each pin available on the Z8 Encore! XP F082A

Series 20- and 28-pin devices. Data in Table 3 is sorted alphabetically by the pin symbol

mnemonic.

Table 4 on page 14 provides detailed information about the characteristics for each pin

available on the Z8 Encore! XP F082A Series 8-pin devices.

All six I/O pins on the 8-pin packages are 5 V-tolerant (unless the pull-up devices are

enabled). The column in Table 3 below describes 5 V-tolerance for the 20- and 28-pin

packages only.
