General description

The SC16C652B is a 2 channel Universal Asynchronous Receiver and Transmitter (UART) used for serial data communications. Its principal function is to convert parallel data into serial data and vice versa. The UART can handle serial data rates up to 5 Mbit/s. The SC16C652B is pin compatible with the SC16C2550. It will power-up to be functionally equivalent to the 16C2450. The SC16C652B provides enhanced UART functions with 32-byte FIFOs, modem control interface, DMA mode data transfer, and IrDA encoder/decoder. The DMA mode data transfer is controlled by the FIFO trigger levels and the TXRDY and RXRDY signals. On-board status registers provide the user with error indications and operational status. System interrupts and modem control features may be tailored by software to meet specific user requirements. An internal loop-back capability allows on-board diagnostics. Independent programmable baud rate generators are provided to select transmit and receive baud rates.

The SC16C652B operates at 5 V, 3.3 V and 2.5 V and the industrial temperature range, and is available in plastic LQFP48 and very small (Micro-UART) HVQFN32 packages.

Features

  • 2 channel UART
  • 5 V, 3.3 V and 2.5 V operation
  • 5 V tolerant inputs
  • Industrial temperature range (-40 Cel. to +85 Cel.)

  • Transmit, Receive, Line Status, and Data Set interrupts independently controlled
  • Fully programmable character formatting:
    • 5-bit, 6-bit, 7-bit, or 8-bit characters
    • Even, odd, or no-parity formats
    • 1, 1 1/2, or 2-stop bit
    • Baud generation (DC to 5 Mbit/s)
  • False start-bit detection
  • Complete status reporting capabilities
  • 3-state output TTL drive capabilities for bi-directional data bus and control bus
