FAMILY DESCRIPTION
The Philips Semiconductors XA (eXtended Architecture) family of
16-bit single-chip microcontrollers is powerful enough to easily
handle the requirements of high performance embedded
applications, yet inexpensive enough to compete in the market for
high-volume, low-cost applications.
The XA family provides an upward compatibility path for 80C51
users who need higher performance and 64k or more of program
memory. Existing 80C51 code can also easily be translated to run
on XA microcontrollers.
The performance of the XA architecture supports the
comprehensive bit-oriented operations of the 80C51 while
incorporating support for multi-tasking operating systems and
high-level languages such as C. The speed of the XA architecture,
at 10 to 100 times that of the 80C51, gives designers an easy path
to truly high performance embedded control.
The XA architecture supports:
•
Instruction set tailored for high level language support
•
Multi-tasking and real-time executives that include up to 32
vectored interrupts, 16 software traps, segmented data memory,
and banked registers to support context switching
•
Low power operation, which is intrinsic to the XA architecture,
includes power-down and idle modes.
More detailed information on the core is available in the XA User
Guide.

Ground:

Power Supply:
This is the power supply voltage for normal, idle, and power down operation.
Port 0:
Port 0 is an 8-bit I/O port with a user-configurable output type. Port 0 latches have 1s
written to them and are configured in the quasi-bidirectional mode during reset. The operation of
port 0 pins as inputs and outputs depends upon the port configuration selected. Each port pin is
configured independently. Refer to the section on I/O port configuration and the DC Electrical
Characteristics for details.
When the external program/data bus is used, Port 0 becomes the multiplexed low data/instruction
byte and address lines 4 through 11.
Port 0 also outputs the code bytes during program verification and receives code bytes during
EPROM programming.

Port 1:
Port 1 is an 8-bit I/O port with a user-configurable output type. Port 1 latches have 1s

port 1 pins as inputs and outputs depends upon the port configuration selected. Each port pin is
configured independently. Refer to the section on I/O port configuration and the DC Electrical
Characteristics for details.
Port 1 also provides special functions as described below.
A0/WRH:
Address bit 0 of the external address bus when the external data bus is
configured for an 8 bit width. When the external data bus is configured for a 16

When the external program/data bus is used in 16-bit mode, Port 2 becomes the multiplexed high
data/instruction byte and address lines 12 through 19. When the external program/data bus is used in
8-bit mode, the number of address lines that appear on port 2 is user programmable.
Port 2 also receives the low-order address byte during program memory verification.
