Description
The 82C50A Asynchronous Communication Element (ACE)
is a high performance programmable Universal Asynchro-
nous Receiver/Transmitter (UART) and Baud Rate Genera-
tor (BRG) on a single chip. Using Intersil’s advanced Scaled
SAJI IV CMOS Process, the ACE will support data rates
from DC to 625K baud (0-10MHz clock).
The ACE’s receiver circuitry converts start, data, stop, and
parity bits into a parallel data word. The transmitter circuitry
converts a parallel data word into serial form and appends
the start, parity, and stop bits. The word length is program-
mable to 5, 6, 7, or 8 data bits. Stop bit selection provides a
choice of 1,1.5, or 2 stop bits.
The Baud Rate Generator divides the clock by a divisor
programmable from 1 to 216-1 to provide standard RS-232C
baud rates when using any one of three industry standard
baud rate crystals (1.8432MHz, 2.4576MHz, or 3.072MHz).
A programmable buffered clock output (BAUDOUT) provides
either a buffered oscillator or 16X (16 times the data rate)
baud rate clock for general purpose system use.
To meet the system requirements of a CPU interfacing to an
asynchronous channel, the modem control signals RTS,
CTS, DSR, DTR, RI, DCD are provided. Inputs and outputs
have been designed with full TTL/CMOS compatibility in
order to facilitate mixed TTL/NMOS/CMOS system design.
