Description
- description
- The TL16C450 is a CMOS version of an asynchronous communications element (ACE). It typically functions in a microcomputer system as a serial input/output interface. The TL16C450 performs serial-to-parallel conversion on data received from a peripheral device or modem and parallel-to-serial conversion on data received from its CPU. The CPU can read and report on the status of the ACE at any point in the ACE’s operation. Reported status information includes the type of transfer operation in progress, the status of the operation, and any error conditions encountered.
- Programmable Baud Rate Generator Allows Division of Any Input Reference Clock by 1 to (216 –1) and Generates an Internal 16× Clock
- Full Double Buffering Eliminates the Need for Precise Synchronization
- Standard Asynchronous Communication Bits (Start, Stop, and Parity) Added or Deleted to or From the Serial Data Stream
- 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
- – Even-, Odd-, or No-Parity Bit Generation and Detection
- – 1-, 1 1/2-, or 2-Stop Bit Generation
- – Baud Generation (dc to 256 Kbit/s)
- False Start Bit Detection
- Complete Status Reporting Capabilities
- 3-State 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
- – Break, Parity, Overrun, Framing Error Simulation
- Fully Prioritized Interrupt System Controls
- Modem Control Functions (CTS, RTS, DSR, DTR, RI, and DCD)
- Easily Interfaces to Most Popular Microprocessors
- Faster Plug-In Replacement for National Semiconductor NS16C450
