NS16C2552/NS16C2752

Dual UART with 16-byte/64-byte FIFO’s and up to

5 Mbit/s Data Rate

1.0 General Description

2.0 Features

n Dual independent UART

The NS16C2552 and NS16C2752 are dual channel Univer-

sal Asynchronous Receiver/Transmitter (DUART). The foot-

print and the functions are compatible to the PC16552D,

while new features are added to the UART device. These

features include low voltage support, 5V tolerant inputs,

enhanced features, enhanced register set, and higher data

rate.

n Up to 5 Mbits/s data transfer rate

n 2.97 V to 5.50 V operational Vcc

n 5 V tolerant I/Os in the entire supply voltage range

n Industrial Temperature: -40˚C to 85˚C

n Default registers are identical to the PC16552D

n NS16C2552/NS16C2752 is pin-to-pin compatible to

NSC PC16552D, EXAR ST16C2552, XR16C2552, XR

16L2552, and Phillips SC16C2552B

n NS16C2752 is compatible to EXAR XR16L2752, and

n Auto Hardware Flow Control (Auto-CTS, Auto-RTS)

n Auto Software Flow Control (Xon, Xoff, and Xon-any)

n Fully programmable character length (5, 6, 7, or 8) with

even, odd, or no parity, stop bit

n Adds or deletes standard asynchronous communication

bits (start, stop, and parity) to or from the serial data

n Independently controlled and prioritized transmit and

receive interrupts

n Complete line status reporting capabilities

n Line break generation and detection

n Internal diagnostic capabilities

The two serial channels are completely independent of each

other, except for a common CPU interface and crystal input.

On power-up both channels are functionally identical to the

PC16552D. Each channel can operate with on-chip transmit-

ter and receiver FIFO’s (in FIFO mode).

In the FIFO mode each channel is capable of buffering 16

bytes (for NS16C2552) or 64 bytes (for NS16C2752) of data

in both the transmitter and receiver. The receiver FIFO also

has additional 3 bits of error data per location. All FIFO

control logic is on-chip to minimize system software over-

head and maximize system efficiency.

To improve the CPU processing bandwidth, the data trans-

fers between the DUART and the CPU can be done using

DMA controller. Signaling for DMA transfers is done through

two pins per channel (TXRDY and RXRDY). The RXRDY

function is multiplexed on one pin with the OUT2 and BAUD-

OUT functions. The configuration is through Alternate Func-

tion Register.

— Loopback controls for communications link fault

isolation

— Break, parity, overrun, framing error detection

n Programmable baud generators divide any input clock

by 1 to (2¹⁶- 1) and generate the 16 X clock

n IrDA v1.0 wireless Infrared encoder/decoder

n DMA operation (TXRDY/RXRDY)

n Concurrent write to DUART internal register channels 1

and 2

n Multi-function output allows more package functions with

fewer I/O pins

The fundamental function of the UART is converting be-

tween parallel and serial data. Serial-to-parallel conversion

is done on the UART receiver and parallel-to-serial conver-

sion is done on the transmitter. The CPU can read the

complete status of each channel at any time. Status infor-

mation reported includes the type and condition of the trans-

fer operations being performed by the DUART, as well as

any error conditions (parity, overrun, framing, or break inter-

rupt).

The NS16C2552 and NS16C2752 include one program-

mable baud rate generator for each channel. Each baud rate

generator is capable of dividing the clock input by divisors of

1 to (2¹⁶- 1), and producing a 16X clock for driving the

internal transmitter logic and for receiver sampling circuitry.

The NS16C2552 and NS16C2752 have complete MODEM-

control capability, and a processor-interrupt system. The

interrupts can be programmed by the user to minimize the

processing required to handle the communications link.
