description
●The TL16C752 is a dual universal asynchronous receiver/transmitter (UART) with 64-byte FIFOs, automatic
●hardware/software flow control, and data rates up to 3.125 Mbps. The ’752 offers enhanced features. It has a transmission control register (TCR) that stores received FIFO threshold level to start/stop transmission during hardware and sofware flow control. With the FIFO RDY register, the software gets the status of TXRDY/RXRDY for all four ports in one access.
●Pin Compatible With ST16C2550 With Additional Enhancements
●Supports Up to 3.125 Mbps Baud Rate
●– Up to 2.1875 Mbps Baud Rate When Using Crystal (35 MHz Input Clock)
●– Up to 3.125 Mbps Baud Rate When Using Oscillator or Clock Source (50 MHz Input Clock)
●64-Byte Transmit FIFO
●64-Byte Receive FIFO With Error Flags
●Programmable and Selectable Transmit and Receive FIFO Trigger Levels for DMA and Interrupt Generation
●Programmable Receive FIFO Trigger Levels for Software/Hardware Flow Control
●Software/Hardware Flow Control
● – Programmable Xon/Xoff Characters
● – Programmable Auto-RTSand Auto-CTS
●Software Flow Control Turned Off Optionally by Any Xon Rx Character
●DMA Signalling Capability for Both Received and Transmitted Data
●Supports 3.3-V Operation
●Software Selectable Baud Rate Generator Prescaleable Clock Rates of 1X and 4X
●Fast Access Time 2 Clock Cycle IOR/IOW Pulse Width
