Description

The ICM7218AIJI is a 8-digit LED microprocessor-compatible Multiplexed Display Decoder Driver. The ICM7218 series of universal LED driver systems provide, all the circuitry necessary to interface most common microprocessors or digital systems to an LED display. Included on chip are an 8-byte static display memory, two types of 7-segment decoders, multiplex scan circuitry and high current digit and segment drivers for either common-cathode or common-anode displays. The lCM7218A feature two control lines (WRITE and MODE) which write either 4 bits of control information (DATA COMING, SHUTDOWN, DECODE and HEXA/CODE B) or 8 bits of display input data. Display data is automatically sequenced into the 8-byte internal memory on successive positive going WRITE pulses. Data may be displayed either directly or decoded in hexadecimal or code B formats.
Microprocessor compatible
Output drive suitable for LED displays directly
Common anode and common cathode versions
Single 5V supply required
Data retention to 2V supply
Shutdown feature - Turns off display and puts chip into low power dissipation mode
Sequential and random access versions
Decimal point drive on each digit
ESD sensitive device, take proper precaution while handling the device.
