XR16C2850

DUAL UART WITH 128-byte FIFOs AND

RS-485 HALF DUPLEX CONTROL

DESCRIPTION

The XR16C2850 (2850) is a dual universal asynchronous receiver and transmitter (UART). The 2850 provides

enhanced UART functions with 128 byte FIFO, automatic RS-485 half duplex control, a modem control interface,

and data rates up to 1.5 Mbps. Onboard status registers provide the user with error indications and operational

status. System interrupts and modem control features may be tailored by external software to meet specific user

requirements. An internal loopback capability allows onboard diagnostics. Independent programmable baud rate

generators are provided to select transmit and receive clock rates up to 1.5 Mbps. The baud rate generator can

be configured for either crystal or external clock input. The 2850 is available in a 40-pin PDIP, 44-pin PLCC, and

48-pin TQFP packages. The 40 pin package does not offer TXRDY and RXRDY pins (DMA Signal monitoring).

Otherwise the three package versions are the same. The 2850 is functionally compatible with the ST16C2550.

The 2850 is fabricated in an advanced CMOS process to achieve low drain power and high speed requirements.

FEATURES

• Pin and functionally compatible to ST16C2550,

software compatible with INS8250, NS16C550

• 1.5 Mbps transmit/receive operation (24 MHz

Max.).

PLCC Package

• 128 byte transmit FIFO to reduce bandwidth re-

quirement of the external CPU.

• 128 byte receive FIFO with error flags to reduce

bandwidth requirement of the external CPU.

• Independent transmit and receive UART control.

• RS-485 half duplex control.

• Programmable transmit/receive FIFO trigger lev-

els.

• Hardware / software flow control.

• Selectable RTS flow control hysterisis.

• Modem control signals (-CTS, -RTS, -DSR, -DTR,

-RI, -CD, and software controllable line break).

• Programmable character lengths (5, 6, 7, 8) with

even, odd, or no parity.

• Infrared receive and transmit encoder/decoder.

• Device identification.

• Crystal or external clock input.
