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 general purpose I/O ports with programmable output configurations.

A default serial loader program in the Boot ROM allows In-System Programming (ISP) of the Flash memory without the need for a loader in the Flash code. User programs may erase and reprogram the Flash memory at will through the use of standard routines contained in the Boot ROM (In-Application Programming).
