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.

SPECIFIC FEATURES OF THE XA-G37

• 20-bit address range, 1 megabyte each program and data space. (Note that the XA architecture supports up to 24 bit addresses.)

• 2.7 V to 5.5 V operation

• 32K bytes on-chip EPROM program memory

• 512 bytes of on-chip data RAM

• Three counter/timers with enhanced features (equivalent to 80C51 T0, T1, and T2)

• Watchdog timer

• Two enhanced UARTs

• Four 8-bit I/O ports with 4 programmable output configurations

• 44-pin PLCC and 44-pin LQFP packages
