1.8-V to 5-V DUAL UART WITH 64-BYTE FIFOS  
FEATURES  
Fully Programmable Serial Interface  
Characteristics:  
Larger FIFOs Reduce CPU Overhead  
– 5-, 6-, 7-, or 8-Bit Characters  
Programmable Auto-RTS and Auto-CTS  
– Even-, Odd-, or No-Parity Bit Generation  
and Detection  
In Auto-CTS Mode, CTS Controls the  
Transmitter  
– 1-, 1 ½-, or 2-Stop Bit Generation  
– Baud Generation (dc to 1 Mbit/s)  
False-Start Bit Detection  
In Auto-RTS Mode, RCV FIFO Contents, and  
Threshold Control RTS  
Serial and Modem Control Outputs Drive a  
RJ11 Cable Directly When Equipment is on  
the Same Power Drop  
Complete Status Reporting Capabilities  
3-State Output TTL Drive Capabilities for  
Bidirectional Data Bus and Control Bus  
Capable of Running With All Existing  
TL16C450 Software  
Line Break Generation and Detection  
Internal Diagnostic Capabilities:  
After Reset, All Registers Are Identical to the  
TL16C450 Register Set  
– Loopback Controls for Communications  
Link Fault Isolation  
Up to 48 MHz Clock Rate for up to 3-Mbps  
(standard 16X sampling) Operation, or up to  
6-Mbps (optional 8X sampling) Operation  
With VCC = 5 V Nominal  
– Break, Parity, Overrun, and Framing Error  
Simulation  
Fully Prioritized Interrupt System Controls  
Up to 32 MHz Clock Rate for up to 2-Mbps  
(standard 16X sampling) Operation, or up to  
4-Mbps (optional 8X sampling) Operation  
With VCC = 3.3 V Nominal  
Modem Control Functions (CTS, RTS, DSR,  
DTR, RI, and DCD)  
Available in 44-Pin PLCC (FN) or 32-Pin QFN  
(RHB) Packages  
Up to 24 MHz Clock Rate for up to 1.5-Mbps  
(standard 16X sampling) Operation, or up to  
3-Mbps (optional 8X sampling) Operation  
With VCC = 2.5 V Nominal  
Each UART's Internal Register Set May Be  
Written Concurrently to Save Setup Time  
Multi-Function Output (MF) Allows Users to  
Select Among Several Functions, Saving  
Package Pins  
Up to 16 MHz Clock Rate for up to 1-Mbps  
(standard 16X sampling) Operation, or up to  
2-Mbps (optional 8X sampling) Operation  
With VCC = 1.8 V Nominal  
APPLICATIONS  
Point-of-Sale Terminals  
Gaming Terminals  
Portable Applications  
Router Control  
Cellular Data  
Factory Automation  
In the TL16C450 Mode, Hold and Shift  
Registers Eliminate the Need for Precise  
Synchronization Between the CPU and Serial  
Data  
Programmable Baud Rate Generator Allows  
Division of Any Input Reference Clock by 1 to  
(216 - 1) and Generates an Internal 16 × Clock  
Standard Asynchronous Communication Bits  
(Start, Stop, and Parity) Added to or Deleted  
From the Serial Data Stream  
5-V, 3.3-V, 2.5-V, and 1.8 V Operation  
Independent Receiver Clock Input  
Transmit, Receive, Line Status, and Data Set  
Interrupts Independently Controlled
