XA-G1

The XA-G1 belongs to the philips semiconductor XA(extended architecture) family of 16-bit single-chip microcontroller is powerful enough to easily handle the requirement of high performance embedded applications, yet inexpensive enough to compete in the market for high-volume, low-cost applications.

Features of the XA-G1 are:(1)20-bit address range,1 megabyte each program and data space; (2)2.7 V to 5.5 V operation; (3)32K bytes on-chip EPROM/ROM program memory=XA-G37/XA-G33; (4)16 K bytes on-chip EPROM/ROM program memory=XA-G27/XA-G23; (5)8K bytes on-chip EPROM/ROM program memory=XA-G17; (6)521 bytes of on-chip data RAM; (7)watchdog timer; (8)two enchanced UARTs; (9)for 8-bit I/O ports with 4 programmable output configurations.

The absolute maximum ratings of the XA-G1 can be summarized as:(1): operating temperature under bias is -55 to +125; (2): storage temperature range is -65 to +150; (3): voltage on EA/V pp pin to Vss us 0 V to +13.0 V; (4): voltage on any other pin to Vss is -0.5 V to VDD+0.5 V; (5): maximum IOL per I/O pin is 15 mA; (6): power dissipation(based on package heat transfer limitations, not device power consumption) is 1.5 W.
