The ST16C2552IJ44 from Exar is a dual universal asynchronous receiver and transmitter (UART) designed for enhanced communication functions. It features 16-byte transmit and receive FIFOs, which help reduce 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 also includes a full modem control interface and DMA operation monitoring. The device is pin-to-pin compatible with National PC16552 and other Exar UARTs.
Key features include 5-volt tolerant inputs, register set compatibility with the 16C550 standard, and 4 selectable RX FIFO trigger levels. The ST16C2552IJ44 is available in a 44-PLCC package, suitable for applications in portable appliances, telecommunication network routers, and factory automation.
It operates over a voltage range of 2.97V to 5.5V and supports programmable character lengths (5, 6, 7, or 8 bits) with even, odd, or no parity. The baud rate generator can be configured for either crystal or external clock input.
