XR21B1422

Enhanced 2-Ch Full-Speed USB UART

FEATURES

General Description

• ±±15k ꢀES ꢁo UEBS+/UEBS-

The XR21B1422 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.

• UEB 2.0 Cꢁmpliaot, Full-Epeed (±2Mbps)

• Uoique pre-prꢁgrammed UEB serial oumber

• Ioteroally geoerated 48MHz cꢁre clꢁc5

• ꢀohaoced UART features

• Baud rates up tꢁ ±2 Mbps

• Fractiꢁoal Baud Rate Geoeratꢁr

• 1±2-byte TX aod 1±2-byte RX FIFOs

• Autꢁ Hardware / Eꢁftware Flꢁw Cꢁotrꢁl

• Multidrꢁp aod Half-Suplex Mꢁdes

• Autꢁ RE-481 Half-Suplex Cꢁotrꢁl

• Eelectable GPIO ꢁr Mꢁdem I/O

• Up tꢁ ±0 GPIOs per chaooel

• 1k tꢁleraot GPIO ioputs

• Euspeod state GPIO cꢁofiguratiꢁo

• Cꢁofigurable clꢁc5 ꢁutput

The XR21B1422 includes an internal oscillator and does not require an

external crystal/oscillator. Any UART baud rate up to 12 Mbps may be

generated with this internal clock and the fractional baud rate generator.

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.

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.

• 40-pio QFN pac5age

• Iodustrial -40°C tꢁ +81°C Temperature Raoge

APPLICATIONS

The XR21B1422 uses the native OS CDC-ACM driver or an Exar supplied

custom driver. Exar provides WHQL/HCK-certified software drivers for

Windows 2000, XP, Vista, 7, 8, 8.1 as well as software drivers for Windows

CE, Linux and Mac OS X. Full source code is available.

• Buildiog Autꢁmatiꢁo

• Eecurity Eystems

• Factꢁry aod Prꢁcess Cꢁotrꢁl

• ATM Termioals

The XR21B1422 operates from a single 5V or 3.3V power supply. When

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

• UEB tꢁ Eerial Cꢁotrꢁllers
