The EDE300 Parallel/ Serial Transceiver IC is a 5 volt, 18 pin package designed to
conveniently convert 8-bit parallel data into serial format and vice-versa. The EDE300 is ideal for
logging data to a PC, controlling hardware via the PC serial port, communicating 8-bit data via a
serial connection, and expanding I/O capabilities on microcontrollers and Stamps. The EDE300 is
BAUD-selectable, offering both 2400 and 9600 BAUD communication. PC connection requires the
use of a voltage level shifter such as the MAX233. The EDE300 can be configured as either a half-
duplex transmitter, a half-duplex receiver, or a half-duplex bi-directional transceiver.
PIN DEFINITIONS
Flow Control Pins:
Data Direction, /Latch (PIN 1):
In
Local Control Mode
pin is an INPUT:
Input of 0 = Parallel to Serial, 1 = Serial to Parallel.
In
Host Control Mode
, pin is an OUTPUT:
EDE300 drives this pin low on receive, high on transmit
0 = 2400 BAUD, (N 8 1); 1 = 9600 BAUD, (N 8 1)
0 =
Local Control Mode
, 1 =
Host Control Mode
Baud Rate (PIN 2):
Mode (PIN 3):
Data Pins:
Serial Transmit (PIN 18) :
Serial Receive (PIN 17):
D0..D7 (PIN 6..PIN 13):
Serial data is output from the EDE300 via this pin
Serial data is input to the EDE300 via this pin
Data I/O Pins (DO is least significant bit)
