Pin Characteristics
Table 4 provides detailed information about the characteristics for each pin available on
Z8 Encore! XP F0823 Series 20- and 28-pin devices. Data in Table 4 is sorted alphabeti-
cally by the pin symbol mnemonic.
Note: All six I/O pins on the 8-pin packages are 5V-tolerant (unless the pull-up devices are
enabled). The right-most column in Table 4 describes 5V tolerance for the 20- and 28-pin
packages only.
