The Exar ST16C2552CJ44 is a dual universal asynchronous receiver and transmitter (UART) designed for enhanced communication functions. It features 16-byte FIFOs for both transmit and receive operations, significantly reducing the bandwidth requirements of the external CPU.
This UART supports independent programmable baud rate generators, allowing for transmit and receive clock rates from 50 bps to 4 Mbps. It offers flexible character lengths (5, 6, 7, or 8 bits) with programmable parity options (even, odd, or none). The device includes a full modem interface and supports DMA operation with monitoring via TXRDY# and RXRDY# pins.
With a wide operating voltage range of 2.97V to 5.5V and 5-volt tolerant inputs, the ST16C2552CJ44 is suitable for various applications. It is pin-to-pin compatible with National PC16552 and Exar's XR16L2752 and XR16C2852. The device is available in a 44-PLCC surface mount package.
Applications include portable appliances, telecommunication network routers, Ethernet network routers, cellular data devices, and factory automation and process controls.
