Serial Data Input
The EDE1400 Serial to Parallel-Printer (Centronics) converter IC is designed to allow printing on
most parallel-interface printers via microcontrollers and BASIC Stamps
. It allows such devices the
ability to create hard-copy output of data or status without the intervention of a PC and without the
I/O or timing demands of the printer's parallel interface. Typical applications include data logging,
status reports, parameter graphing, etc. Data is written to the EDE1400 over a single serial data wire
at 2400 Baud. The EDE1400 generates the appropriate printer control signals as well as monitors
printer status to cause the incoming serial stream to be printed on the parallel printer, thus allowing
designers the ability to use the less-expensive and more readily available parallel-type printers as
opposed to the more costly serial-input printers. The EDE1400 can also be used with most PC's,
allowing data to be sent to most parallel printers over a single serial wire; hardware handshaking
signals are also generated by the EDE1400 to allow it to communicate properly with the PC.
Connection to most microcontrollers, stamps, or microprocessors can be made using a single data
wire, without any type of voltage level conversion.
Some of the special features of the EDE1400 are as follows:
Directly receives RS-232 data from microcontrollers or Stamps
Single-chip design is ideal for embedded designs
Prints any ASCII character on most Centronics/Parallel type printers
Monitors printer status for reliable operation
Allows printed data to be sent over a single wire
Internal watchdog timer allows for trouble-free operation
Operates from single + 5V supply
2400 Baud serial input data rate (2400 N-8-1)
Available in 18 pin DIP or SOIC packages
