Down.Wake-Up from power-down via an external inter-
rupt is supported.
鈥?44-pin PLCC (MX10EXAQC) and 44-pin LQFP
(MX10EXAUC) packages
GENERAL DESCRIPTION
The MX10EXA is a member of Philips鈥?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.
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).
