GENERAL DESCRIPTION
The MX10EXA is a member of Philips’ 80C51 XA
(eXtended Architecture) family of high performance 16-
bit single-chip microcontrollers.
The MX10EXA contains 64k bytes of Flash program
memory, and provides three general purpose timers/
counters, a watchdog timer, dual UARTs, and four gen-
eral purpose I/O ports with programmable output con-
figurations.

PIN CONFIGURATIONS
44 PLCC
A default serial loader program in the Boot ROM allows
In-System Programming (ISP) of the Flash memory with-
out the need for a loader in the Flash code. User pro-
grams may erase and reprogram the Flash memory at
will through the use of standard routines contained in
the Boot ROM (In-Application Programming).
