ST16C2552 Datasheet 2.97v To 5.5v Dual Uart With 16-byte Fifo

Manufacturer: Exar (now MaxLinear)

Overview: áç SEPTEMBER 2003 ST16C2552 2.97V TO 5.5V DUAL UART WITH 16-BYTE FIFO REV. 4.

Datasheet Details

The ST16C2552 (2552) is a dual universal asynchronous receiver and transmitter (UART).

The ST16C2552 is an improved version of the PC16552 UART.

The 2552 provides enhanced UART functions with 16 byte FIFOs, a modem control interface, and data rates up to 4 Mbps.

may be tailored by external software to meet specific user requirements. Indepedendent programmable baud rate generators are privded to select transmit and receive clock rates from 50 Bps to 4 Mbps. The baud rate generator can be configured for either crystal or external clock input. An internal loop-back capability allows onboard diagnostics. The 2552 provides block mode data transfers (DMA) through FIFO controls. DMA transfer monitoring is provided through the signals TXRDY# and RXRDY#. An Alt.
