SC16C750
Universal Asynchronous Receiver/Transmitter (UART)
with 64-byte FIFO
Rev. 04 鈥?20 June 2003
Product data
1. General description
The SC16C750 is a Universal Asynchronous Receiver and Transmitter (UART) used
for serial data communications. Its principal function is to convert parallel data into
serial data, and vice versa. The UART can handle serial data rates up to 3 Mbits/s.
The SC16C750 is pin compatible with the TL16C750 and it will power-up to be
functionally equivalent to the 16C450. Programming of control registers enables the
added features of the SC16C750. Some of these added features are the 64-byte
receive and transmit FIFOs, automatic hardware 鏗俹w control. The selectable
auto-鏗俹w control feature signi鏗乧antly reduces software overload and increases
system ef鏗乧iency while in FIFO mode by automatically controlling serial data 鏗俹w
using RTS output and CTS input signals. The SC16C750 also provides DMA mode
data transfers through FIFO trigger levels and the TXRDY and RXRDY signals.
On-board status registers provide the user with error indications, operational status,
and modem interface control. System interrupts may be tailored to meet user
requirements. An internal loop-back capability allows on-board diagnostics.
The SC16C750 operates at 5 V, 3.3 V and 2.5 V, the industrial temperature range and
is available in plastic PLCC44 and LQFP64 packages.
