SER7 IC

Serial to Seven Segment Controller

Expandable to 32 digits

General Description

The SER7 IC is a bridge between serial interfaces and one or two non multiplexed seven

segment displays. Data is received in a 32 byte buffer, and translated from ASCII to seven

segment codes when a carriage return (Hex 0D) is received. More than one SER7 chip may be

connected together to achieve up to 32 digits of display. The SER7 has internal pull resistors on

most inputs to minimize additional parts.

The SER7 may connect to RS-232, USB, RS-485, Ethernet or directly to your UART. The serial

format to the SER7 is standard ASCII asynchronous format, using 8 bits, 1 stop and no parity at

9600 BPS. Other formats and encoding are available, contact the factory. A .1 uF bypass

capacitor is suggested across the VDD and VSS pins. The part uses the standard 28 pin .3 inch

width SOIC and DIP package.
