Product Summary
The TL16C550CFNRG4 is an asynchronous communications element with autoflow control. The TL16C550CFNRG4 is functional upgrades of the TL16C550B asynchronous communications element (ACE), which in turn is a functional upgrade of the TL16C450. Functionally equivalent to the TL16C450 on power up (character or TL16C450 mode), the TL16C550CFNRG4, like the TL16C550B, can be placed in an alternate FIFO mode. This relieves the CPU of excessive software overhead by buffering received and transmitted characters. The receiver and transmitter FIFOs store up to 16 bytes including three additional bits of error status per byte for the receiver FIFO.
Parametrics
TL16C550CFNRG4 absolute maximum ratings: (1)Supply voltage range, VCC: –0.5 V to 7 V; (2)Input voltage range at any input, VI: –0.5 V to 7 V; (3)Output voltage range, VO:–0.5 V to 7 V; (4)Operating free-air temperature range, TA: 0 to 70℃; (5)Storage temperature range, Tstg : –65 to 150℃; (6)Case temperature for 10 seconds, TC: 260℃; (7)Lead temperature 1,6 mm (1/16 inch) from case for 10 seconds: 260℃.
Features
TL16C550CFNRG4 features: (1)Serial and Modem Control Outputs Drive a RJ11 Cable Directly When Equipment Is on the Same Power Drop; (2)Capable of Running With All Existing TL16C450 Software; (3)After Reset, All Registers Are Identical to the TL16C450 Register Set; (4)Up to 16-MHz Clock Rate for up to 1-Mbaud Operation; (5)In the TL16C450 Mode, Hold and Shift Registers Eliminate the Need for Precise Synchronization Between the CPU and Serial Data; (6)Programmable Baud Rate Generator Allows Division of Any Input Reference Clock by 1 to (216 –1) and Generates an Internal 16× Clock; (7)Standard Asynchronous Communication Bits (Start, Stop, and Parity) Added to or Deleted From the Serial Data Stream.
