The EDE1400 Serial to Parallel-Printer (Centronics) converter IC is designed to allow printing on

most parallel-interface printers via microcontrollers and BASIC Stampsâ¢. 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:

â¢ Directly receives RS-232 data from microcontrollers or Stamps

â¢ Single-chip design is ideal for embedded designs

â¢ Prints any ASCII character on most Centronics/Parallel type printers

â¢ Monitors printer status for reliable operation

â¢ Allows printed data to be sent over a single wire

â¢ Internal watchdog timer allows for trouble-free operation

â¢ Operates from single +5V supply

â¢ 2400 Baud serial input data rate (2400 N-8-1)

â¢ Available in 18 pin DIP or SOIC packages
