XR16C850CJ

The XR16C850CJ is designed as a universal asynchronous receiver and transmitter (UART). This device supports intel and PC mode data bus interface and is software compatible to industry standard 16C450, 16C550, ST16C580 and ST16C650A UARTs. Typical applications include battery operated electronics, internet appliances, handheld terminal, personal digital assistants, cellular phones dataPort and wireless infrared data communications systems.

XR16C850CJ has ten features. (1)2.97 to 5.5volt operation. (2)Pin to pin compatible to ST16C550, ST16C580, ST16C650A and TL16C750. (3)128byte transmit and receive FIFOs. (4)Transmit /receive FIFO counters. (5)Programmable TX/RX FIFO trigger levels. (6)Automatic hardware /software flow control. (7)Auto RS-485 half duplex direction support. (8)Programmable Xon /Xoff characters. (9)Infrared (IrDA) TX and RX encoder /decoder. (10)Sleep mode (100uA stand-by). That are all the main features.

Some absolute maximum ratings of XR16C850CJ have been concluded into several points as follow. (1)Its power supply range would be 7volts. (2)Its voltage at any pin would be from GND-0.3V to 7V. (3)Its operating temperature range would be from -40°C to +85°C. (4)Its storage temperature range would be from -65°C to +150°C. (5)Its package dissipation would be 500mW. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of XR16C850CJ at limits 3.3V are concluded as follow. (1)Its clock input low level would be min -0.3V and max 0.6V. (2)Its clock input high level would be min 2.4V and max Vcc. (3)Its input low voltage would be min -0.3V and max 0.8V. (4)Its input high voltage (top mark date code of "EC YYWW" and older) would be min 2.0V and max Vcc. (5)Its input high voltage (top mark date code of "F2 YYWW" and newer) would be min 2.0V and max 5.5V. And so on.
