The EDE702 Serial LCD Interface IC has been designed to provide a cost-effective LCD control

solution for a wide variety of embedded designs. Offering the most frequently used features of the

popular EDE700 IC (plus an added digital output line & lower crystal frequency), the EDE702

provides a tremendous price/ performance ratio. It allows nearly any text-based LCD module to be

controlled via a simple one-wire data link, freeing an additional 6 to 10 I/O lines on your

microcontroller/ microprocessor system - which frequently allows a smaller, less costly

microcontroller to be utilized in your design.

The EDE702 allows full LCD control, including the creation of custom characters. Also, in addition

to complete screen control, the EDE702 provides a convenient serial-controlled digital output pin

for lighting an indicator LED, driving a sounder, etc. With a 2400 or 9600 Baud rate and selectable

serial data polarity, the EDE702 can easily communicate with any device capable of sending

asynchronous serial data. Connection to most microcontrollers, stamps, or microprocessors can be

made using a single data wire without any type of voltage level conversion. Connection to a PC

requires only a 33KW resistor.

Some of the special features of the EDE702 are as follows:

· RS232 and TTL-level compatible

· Single-chip design allows for easy system integration

· Compatible with most 1x8 to 2x40 character HD44780 controlled LCDs

· Useable with LCDs having either 1x14 or 2x7 connector configuration

· Allows direct control of all LCD module functions

· Offers serial-controlled digital output line

· Selectable data polarity eliminates necessity of RS-232 voltage converter

· 2400/9600 Baud data rates

· Available in 18 pin DIP or SOIC packages

· Cost-effective in OEM applications
