XR21B1424

Enhanced 4-Ch Full-Speed USB UART

FEATURES

General Description

• 15kV ESD on USBD+/USBD-

The XR21B1424 is an enhanced Universal Asynchronous Receiver and

Transmitter (UART) bridge to USB interface. The USB interface is fully

compliant to the USB 2.0 (Full-Speed) specification with 12 Mbps USB

data transfer rate. The USB interface also supports USB suspend,

resume and remote wakeup operations. The USB Vendor ID, Product ID,

power mode, remote wakeup support, maximum power, and numerous

other settings may be programmed in the on-chip OTP memory via the

USB interface.

• USB 2.0 Compliant, Full-Speed (12Mbps)

• Unique pre-programmed USB serial number

• Internally generated 48MHz core clock

• Enhanced UART features

• Baud rates from 300 bps to 12 Mbps

• Fractional Baud Rate Generator

• 512-byte TX and 512-byte RX FIFOs

• Auto Hardware / Software Flow Control

• Multidrop and Half-Duplex Modes

• Auto RS-485 Half-Duplex Control

• Selectable GPIO or Modem I/O

• Up to 10 GPIOs per channel

The XR21B1424 includes an internal oscillator and does not require an

external crystal/oscillator. Any UART baud rate from 300 bps to 12 Mbps

may be generated with this internal clock and the fractional baud rate gen-

erator.

The UART pins for each port may also be configured as GPIO; direction,

state, output driver type and input pull-up or pull-down resistors are pro-

grammed either through on chip OTP, or on the fly via memory mapped

registers.

• 5V tolerant GPIO inputs

• Suspend state GPIO configuration

• Configurable clock output

• 64-pin LQFP package

Large 512-byte TX and RX FIFOs prevent buffer overflow errors and opti-

mize data throughput. Automatic half-duplex direction control and optional

multi drop (9-bit) mode simplify both hardware and software in half-duplex

RS-485 applications. Wide mode allows for each individual received char-

acter to be monitored for errors.

• Industrial -40°C to +85°C Temperature

Range

APPLICATIONS

• Building Automation

• Security Systems

The XR21B1424 uses the native OS CDC-ACM driver or a MaxLinear

supplied custom driver. MaxLinear provides WHQL/HCK-certified soft-

ware drivers for Windows 2000, XP, Vista, 7, 8, 8.1 and 10 as well as soft-

ware drivers for Windows CE, Linux and Mac OS X. Full source code is

available.

• Factory and Process Control

• ATM Terminals

• USB to Serial Controllers

The XR21B1424 operates from a single 5V or 3.3V power supply. When

powered with 5V input, a regulated 3.3V output is supplied.
