Quick Detail:
DUAL ASYNCHRONOUS RECEIVER/TRANSMITTER WITH FIFOs
Description:
The ST16C2552 is a dual asynchronous receiver and transmitter with 16 byte transmit and receive FIFOs.
Independent programmable baud rate generators are provided to select transmit and receive clock rates from 50Hz to 1.5 MHz for each UART.
The on board status registers of the ST16C2552 provide the error conditions, type and status of the transfer operation being performed. Complete MODEM control capability and a processor interrupt system that may be software tailored to the user’s requirements are included. The ST16C2552 provides internal loop-back capability for on board diagnostic testing.
Signalling for DMA transfers is done through two pins per channel ( TXRDY*, RXRDY* ). The RXRDY* function is multiplexed on one pin with the OP2* and
BAUDOUT functions. CPU can select these functions through the Alternate Function Register.
The ST16C2552 is fabricated in an advanced 0.6m CMOS process to achieve low power and high speed requirements.
Applications:
·Pin to pin and functional compatible to National NS16C552

·Programmable character lengths (5, 6, 7, 8) bits
·Even, odd, or no parity bit generation and detection
·Status report register
·TTL compatible inputs, outputs
· Independent transmit and receive control
·Software compatible with INS8250, NS16C550
· 460.8 kHz transmit/receive operation with 7.372 MHz crystal or external clock source
