PXAS37KBA

The PXAS37KBA is a member of Philips Semiconductors' XA family of high performance 16-bit single-chip microcontrollers. The features of PXAS37KBA are: (1)2.7 V to 5.5 V operation.; (2)32 K bytes of on-chip EPROM/ROM program memory.; (3)1024 bytes of on-chip data RAM.; (4)Supports off-chip addressing up to 16 megabytes (24 address lines). A clock output reference is added to simplify external bus interfacing. .

The following is about the absolute maximum ratings of PXAS37KBA: (1)Operating temperature under bias: 55 to +125 °C; (2)Storage temperature range: 65 to +150 °C; (3)Voltage on EA/VPP pin to VSS: 0 to +13.0 V; (4)Voltage on any other pin to VSS: 0.5 to VDD+0.5 V V; (5)Maximum IOL per I/O pin: 15 mA; (6)Power dissipation (based on package heat transfer, not device power consumption): 1.5 W.

The electrical characteristics of the PXAS37KBA are: (1)Power supply current, operating: 80mA max at 5.0 V, 30 MHz; (2)Power supply current, Idle mode: 35mA max at 5.0 V, 30 MHz; (3)Power supply current, Power Down mode: 5A typical and 100A max at 5.0 V, 3.0 V or 150A max at 5.0 V, 3.0 V, 40 to +85°C; (4)RAM keep-alive voltage: 1.5 V; (5)Input low voltage: -0.5V min and 0.22 VDD V max ; (6)Input high voltage, except XTAL1, RST: 2.2 V min at VDD = 5.0 V or 2.0V at VDD = 3.0 V; (7)Input high voltage to XTAL1, RST: 0.7 VDD V For both 3.0 V and 5.0 V.
