Product Highlight

  • Data Rate: 5 Mbps
  • Supply Voltage-Nom: 2.5 to 5 V

The SC16C752B is a dual Universal Asynchronous Receiver/Transmitter (UART) with 64-byte FIFOs, automatic hardware/software flow control, and data rates up to 5 Mbit/s (3.3 V and 5 V). The SC16C752B offers enhanced features. It has a Transmission Control Register (TCR) that stores receiver FIFO threshold levels to start/stop transmission during hardware and software flow control. With the FIFO Rdy register, the software gets the status of TXRDYn/RXRDYn for all four ports in one access. On-chip status registers provide the user with error indications, operational status, and modem interface control. System interrupts may be tailored to meet user requirements. An internal loopback capability allows on-board diagnostics.

Features and benefits:

  • Pin compatible with SC16C2550 with additional enhancements
  • Up to 5 Mbit/s baud rate (at 3.3 V and 5 V; at 2.5 V maximum baud rate is 3 Mbit/s)
  • 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
  • Optional data flow resume by Xon any character
  • DMA signalling capability for both received and transmitted data
  • Supports 5 V, 3.3 V and 2.5 V operation
  • 5 V tolerant on input only pins1
  • Software selectable baud rate generator
  • Prescaler provides additional divide-by-4 function
  • Industrial temperature range (−40 °C to +85 °C)
  • Pin and software compatible with SC16C752, TL16C752
  • Fast data bus access time
  • Programmable Sleep mode
