Preliminary
8.3 Memory Maps
The width of the GPIO port defines how many bits are implemented in each of the GPIO registers.
Based on this and the default function of each of the GPIO pins, the reset values of the GPIOx_PUR
and GPIOx_PER registers will change from port to port. Tables 4-29 through 4-34 define the actual
reset values of these registers for the 56F8355.

Part 10 Specifications
10.1 General Characteristics
The 56F8355 is fabricated in high-density CMOS with 5V-tolerant TTL-compatible digital inputs.
The term “5V-tolerant” refers to the capability of an I/O pin, built on a 3.3V-compatible process
technology, to withstand a voltage up to 5.5V without damaging the device. Many systems have a
mixture of devices designed for 3.3V and 5V power supplies. In such sytems, a bus may carry both
3.3V- and 5V-compatible I/O voltage levels (a standard 3.3V I/O is designed to receive a
maximum voltage of 3.3V
± 10% during normal operation without causing damage). This
5V-tolerant capability therefore offers the power savings of 3.3V I/O levels combined with the
ability to receive 5V levels without damage.
Absolute maximum ratings in Table 10-1 are stress ratings only, and functional operation at the
maximum is not guaranteed. Stress beyond these ratings may affect device reliability or cause
permanent damage to the device.
Note:
All specifications meet both Automotive and Industrial requirements unless individual
specifications are listed.
CAUTION
This device contains protective circuitry to guard
against damage due to high static voltage or electrical
fields. However, normal precautions are advised to
avoid
application
of
any
voltages
higher
than
maximum-rated voltages to this high-impedance circuit.
Reliability of operation is enhanced if unused inputs are
tied to an appropriate voltage level.
