XR20V2170 - I2C/SPI UART

General Description

The XR20V21701 (V2170) is a high performance universal asynchronous receiver and transmitter (UART) with 64 byte TX and RX FIFOs, a selectable I2C/SPI slave interface and RS232 transceiver.

The V2170 operates from 2.97 to 3.63 volts.

Key Features

  • in the V2170 include a programmable fractional baud rate generator, an 8X and 4X sampling rate that allows for a maximum baud rate of 250 Kbps at 3.3V. The standard features include 16 selectable TX and RX FIFO trigger levels, automatic hardware (RTS/CTS) and software (Xon/ Xoff) flow control, and a complete modem interface. Onboard registers provide the user with operational status and data error flags. An internal loopback capability allows system diagnostics. The V2170 is available in the 40-.
