• Manufacturer Part Number: saf-xc888cm-8ffi5v
• Description: 8-bit Single-chip Microcontroller
• Manufacturer: Infineon Technologies Corporation

3.5
The XC886 has 34 port pins organized into five parallel ports, Port 0 (P0) to Port 4 (P4),
while the XC888 has 48 port pins organized into six parallel ports, Port 0 (P0) to Port 5
(P5). Each pin has a pair of internal pull-up and pull-down devices that can be individually
enabled or disabled. Ports P0, P1, P3, P4 and P5 are bidirectional and can be used as
general purpose input/output (GPIO) or to perform alternate input/output functions for the
on-chip peripherals. When configured as an output, the open drain mode can be
selected. Port P2 is an input-only port, providing general purpose input functions,
alternate input functions for the on-chip peripherals, and also analog inputs for the
Analog-to-Digital Converter (ADC).
