1.8-V to 5-V DUAL UART WITH 64-BYTE FIFOS
SLWS188 – JUNE 2006
FEATURES
• Larger FIFOs Reduce CPU Overhead
• Programmable Auto-RTS and Auto-CTS
• In Auto-CTS Mode, CTS Controls the
Transmitter
• 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
• Capable of Running With All Existing
TL16C450 Software
• After Reset, All Registers Are Identical to the
TL16C450 Register Set
• 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 V_CC = 5 V Nominal
• 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 V_CC = 3.3 V Nominal
• 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 V_CC = 2.5 V Nominal
• 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 V_CC = 1.8 V Nominal
• 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
• Fully Programmable Serial Interface
Characteristics:
– 5-, 6-, 7-, or 8-Bit Characters

• False-Start Bit Detection
• Complete Status Reporting Capabilities
• 3-State Output TTL Drive Capabilities for
Bidirectional Data Bus and Control Bus
• Line Break Generation and Detection
• Internal Diagnostic Capabilities:
– Loopback Controls for Communications
Link Fault Isolation

Simulation
• Fully Prioritized Interrupt System Controls
• Modem Control Functions (CTS, RTS, DSR,
DTR, RI, and DCD)
• Available in 44-Pin PLCC (FN) or 32-Pin QFN
(RHB) Packages
• 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
